Who we are

We've built dozens of tools for creators and sold three of those businesses for seven figures or more. Now we're building our own platform where creators can sell subscriptions and PPV content, chat with fans, livestream and receive payouts. We have $10m in funding.

Who we're looking for

You'll own the iOS and Android app, which we're building from scratch with React Native, Expo and TypeScript. You'll work with our designers and the engineers building the backend and web app.

What you'll do

• Build the iOS and Android app in Expo and TypeScript.
• Ship to both stores and maintain the app after release. You'll handle builds, signing, app review, updates, crash reporting and push notifications.
• Add camera and media capture, secure storage and identity checks using Expo and React Native libraries. Handle background uploads and recover from interrupted transfers.
• Build payments, subscriptions and paywalls. Make sure restored purchases and failed payments leave users with the right access.
• Make chat work when people lose connection and come back. Keep long conversations fast to load and smooth to scroll, and handle messages sent while offline.
• Work in our monorepo. Share API types, client code and design tokens with web, and share UI components where they work on both platforms.

We expect you to look at the Laravel code when an API doesn't give the app what it needs, and work with the backend team to fix it.

What we need from you

• You know TypeScript well and have shipped and maintained React Native and Expo apps with real users. If you've sold an app you built, we'd like to hear about it.
• You've shipped mobile payments, subscriptions and paywalls. You know how to restore purchases and keep paid access in sync with the backend.
• You've taken iOS and Android apps through App Store and Google Play review.
• You understand the stores' billing rules and when you can use external payments.
• You can integrate native libraries in Expo development builds and debug problems on iOS and Android, including build and configuration issues.
• You can track down crashes, slow screens and connection problems on real phones. You understand how backgrounding, force-quit or force-stop, and reopening affect the app's work and recovery.
• You have a good eye for UI and UX. You build beautiful interfaces that feel good to use, with thoughtful transitions, animations and small interactions. When a design leaves out a state or interaction, you can work out what fits.

It's a plus if you've worked on a creator or UGC platform and dealt with its moderation rules. Experience with KYC or age checks, WebRTC, livestreaming, shared design systems or monorepos also helps. Writing Swift or Kotlin modules is a bonus.

Why join us

We already have an audience we can launch this app to. You'll work directly with us in a small team and make decisions about how we build it. The backend uses Laravel, PostgreSQL, Reverb and R2.

How we hire

One paid technical task, then a 30-minute walkthrough. No panel interviews. You have six-seven 🤷‍♂️ hours, including setup. You can use AI; we'll ask you to explain your code and decisions.

Engagement: Freelance / contract only 

Workload: Depends on the project — typically 4–12 weeks per project, with repeat work

About the role

We design product interfaces and marketing sites for SaaS, fintech, e-commerce and Web3 clients. A growing share of them can't be built in Webflow — headless storefronts, design-system implementations, high-motion sites, component libraries handed over to in-house engineering teams. That's where you come in.

You'll work from Figma files our team produces, with direct access to the designers.

What you'll do

• Build production frontends in React / Next.js / TypeScript from Figma designs
• Implement design systems in code: design tokens, component libraries with full variant and state matrices, dark and light themes, Storybook
• Work with and extend shadcn/ui + Tailwind setups — several clients run this stack and expect designs to map onto it without custom CSS
• Build headless frontends against client-provided APIs and CMSs (Sanity, Storyblok, Contentful), including e-commerce storefronts with search and faceting (Algolia) and payment integrations (Stripe and similar)
• Implement complex motion: scroll-driven transitions, parallax, GSAP ScrollTrigger, Framer Motion, Lottie — at 60 FPS with GPU-accelerated transforms
• Build data-dense UI: dashboards, tables, filters, charts (Recharts, D3)
• Deliver responsive down to 320px with accessibility basics covered
• Hand off documented, prop-typed components the client's engineers can pick up
• Produce hours-based estimates for incoming leads within 24–48 hours

Must-have

• 4+ years commercial frontend; strong React + TypeScript
• Next.js in production: App Router, SSR/SSG, routing, data fetching
• Tailwind CSS, and experience mapping design tokens from Figma into a Tailwind config
• Component library work: variants, states, sizes, composition, documented props
• Real animation experience, not just CSS transitions — GSAP or Framer Motion in production
• REST/GraphQL integration with proper loading, empty and error states
• Git, code review, clean commit hygiene
• AI-assisted development. Claude Code (or equivalent) is part of how you work day to day — scaffolding components, refactoring, writing tests, exploring unfamiliar APIs. You can go from a Figma screen or a brief to a working clickable prototype fast, using AI to compress the first 80%, then take it to production quality yourself. You review AI output critically and don't ship it unread.
• English B2 or higher — you'll join client technical calls

• Security judgement: we regularly receive leads asking us to clone and run their repository. You must be able to recognise suspicious code and refuse to run it — this came up four separate times in 2026.

   

Nice to have

• shadcn/ui and Storybook
• Headless CMS: Sanity, Storyblok, Contentful, Strapi
• E-commerce at scale: Algolia, faceted search, large catalogues (1M+ SKUs), Stripe and regional payment providers
• Three.js, WebGL or React Three Fiber for 3D web experiences
• Vercel deployment and Core Web Vitals optimisation
• Web3: wallet connect, contract reads

• Ability to also work in Webflow for hybrid projects

   

Soft requirements

• Product thinking: you challenge a design if it will be slow, inaccessible or unmaintainable
• Comfortable working directly with designers, not just tickets

• Clear async written communication

   

Application

Send 2–3 live projects with your role described, a link to a component library or Storybook you built, an example of a prototype you assembled with AI tooling, your rate and availability.

About the Role

We’re a lean product team developing a consumer commerce platform that combines real-time 3D interactions with the purchase of physical products. The product also includes a real-money wallet and operational workflows for order processing and fulfillment.

Our technology stack is built entirely around TypeScript. The engineering team is small and experienced, with engineers working closely with and reporting directly to the CTO, allowing for fast communication and decision-making.

We’re looking for a Senior Mobile Engineer to lead the development of a native mobile application for an existing consumer product with rich, real-time 3D interactions.

You’ll take ownership of the React Native application from initial architecture through production release on both iOS and Android. A major part of the role will be translating an existing interactive web experience into a smooth native product, including animations, gestures, and platform-specific functionality.

This is not a mobile-only position. Engineers are encouraged to own features end to end, including the supporting APIs, asynchronous processing, and database changes. The backend is built with Node.js and TypeScript, so experience working beyond the mobile layer is highly valued.

What You'll Do

• Design and develop the mobile application using React Native, Expo, and TypeScript, from initial setup through App Store and Google Play releases.
• Build high-quality animations and gesture-based interactions using tools such as Reanimated, Gesture Handler, and Skia, with a strong focus on smooth performance.
• Implement payment functionality, wallet-related experiences, and reliable synchronization between client-side state and backend financial records.
• Work with native functionality when required, including push notifications, secure storage, media playback, deep linking, and platform-specific payment integrations.
• Own features across the stack when needed: define API contracts, develop Fastify endpoints and background processes, implement the mobile experience, and add appropriate monitoring and instrumentation.
• Establish and maintain the mobile delivery process, including builds, signing, store submissions, OTA updates, and crash reporting using EAS, fastlane, or similar tooling.

What We're Looking For

• 5+ years of professional mobile development experience, including at least 3 years working with React Native applications released to production.
• Strong TypeScript skills and practical familiarity with Swift and/or Kotlin for debugging, understanding native issues, and implementing platform-specific functionality when necessary.
• Hands-on experience building complex mobile animations and gesture-driven interfaces.
• Understanding of mobile performance and the ability to create responsive, smooth user experiences.
• Practical backend knowledge, ideally including Node.js APIs, relational databases, and asynchronous processing or message queues.
• Ability to take ownership of features beyond the mobile interface and contribute to their server-side implementation is strongly preferred.
• Experience with payments, digital wallets, or other transaction-heavy consumer applications is a significant advantage.

Nice to Have

• Experience with mobile 3D technologies such as Three.js, react-three-fiber, SceneKit, or GPU-accelerated Skia.
• Experience handling complex video and media playback scenarios on mobile.
• Previous experience transforming an established web product into native iOS and Android applications while maintaining a consistent product experience.

About 4goo

We're building a social network for web and mobile — think rich user profiles, real-time messaging,
media feeds, and the scale that comes with it. Our backend is Go microservices on Kubernetes, and
every contract between backend and clients is formalised: OpenAPI for HTTP, AsyncAPI for the
realtime layer.

We're building our entire client layer from scratch — web, iOS and Android — as one monorepo owned
by one team. The first commit hasn't been written yet. We haven't launched publicly, the design
system is finished in Figma and being exported to code, and whoever joins now shapes how this gets
built rather than inheriting someone else's decisions.

The Role

You own product surfaces end to end — one person, one feature, three platforms. Not "the web
version" or "the iOS version." The feature.

Next.js on web, Expo on iOS and Android, one monorepo, with most UI written once through a universal
component layer. That means what you build has to be genuinely good in a browser and genuinely good
on a phone — which are not the same problem, even from the same code.

You're one of the first two hires on this team, so the patterns are partly yours. You're not working
a ticket queue — you're deciding what needs building, saying what needs changing, and making it
happen.

What You'll Work On

- Feed, reels and stories. Virtualized lists that stay smooth under real data, and a vertical
 video pager with preloading and a memory budget that actually holds. This is where most
 cross-platform apps fall over. If you've solved it before, we want to talk.
- Real-time chat and in-app notifications. WebSockets against an AsyncAPI-defined contract:
 message ordering, optimistic updates, reconnection, and a chat window that stays correct while
 five things happen at once.
- Media. Capture, chunked and resumable upload, playback, in-app editing — across three
 platforms with genuinely different capabilities.
- Building on the generated design system. The Figma is finished and exported to code. You'll
 compose product surfaces from those primitives in Storybook — and push back when a primitive is
 wrong rather than working around it.
- Performance as an owned metric, on native and web both — measured, budgeted, and defended in
 review.

What We're Looking For

Must have:

- 5+ years building with React, with strong TypeScript
- React Native shipped to production, ideally to both app stores
- Comfortable on web and native both — you're not looking to specialise in one and tolerate the other
- You've built something at this complexity before — real-time, media, infinite feeds, optimistic
 updates. You know why the second one is harder than the first
- Performance is something you measure, not something you assert: frame rates, memory, bundle size,
 re-render cost
- You own things. You pick up the problem, decide what needs doing, and say what you're doing.
 Nobody here will be assigning you tickets
- You think about the product. You'll notice when something in the design won't work before you
 build it, and say so — we'd rather have that conversation than ship the wrong thing on time

Strong plus:

- Storybook as part of how you actually work, not an afterthought
- Building against a design system rather than one-off screens
- Universal / cross-platform UI layers — Tamagui, react-strict-dom, Unistyles or similar
- Next.js in production
- Expo and EAS, including OTA updates
- Video-heavy or feed-heavy consumer products
- Media capture, upload and playback pipelines
- Real-time — reconnection, ordering, presence
- Generated clients from OpenAPI or AsyncAPI specs
- Working in a monorepo

Working With AI Agents

We build with AI agents deliberately, and we're looking for people who are genuinely good at it —
not "I've tried Copilot."

The reason is specific. The design system is finished. The backend contracts are fixed and
machine-readable. The team is small on purpose. Our constraint isn't deciding what to build — it's
implementation throughput at a quality bar, which is exactly where agents earn their keep and
exactly where sloppy use costs you.

We mean the practical skill: giving an agent the right context, scoping work so the output can
actually be verified, knowing when to hand off and when to write it yourself, and reviewing
generated code properly.

If you have opinions about how this should work, we want to hear them.

What Good Looks Like in This Role

In your first month you're shipping real screens to web and native from the shared design system —
and already arguing about the patterns rather than just following them.

Six months in, you own a surface. Feed, chat, media — whichever fits you. It works on every
platform, the people around you route questions about it to you, and its performance story is
something you can defend with numbers.

Stack

Decided: React · Next.js · React Native · Expo (EAS) · TypeScript · monorepo · Storybook ·
OpenAPI + AsyncAPI generated clients · WebSockets · GitLab CI

Still open: the universal UI approach · data and caching layer · testing strategy. You'll have a
say.

Backend is Go microservices on AWS — you won't write it, but you'll design against it.

Interview Process

1. Intro call — what you've built, what you want to own.
2. Technical conversation about the real problems in front of this team. No whiteboard algorithms.
3. Offer.

What We Offer

- A codebase you start rather than inherit
- Real influence on architecture, before launch, while the decisions are still open
- Ownership of whole features across three platforms, not slices of one
- A small team by design, not by circumstance
- Direct access to decision-makers — no layers between you and the people setting direction
- Remote-friendly, async-first culture
- Competitive compensation based on experience

*Please include something you've built — ideally something with a real feed, real video, or real
users — and, if you can, a sentence on how you actually use AI agents day to day.*

Привіт, майбутній дев нашої команди! Ми — молода, енергійна команда, яка створює крутий мобільний додаток, і нам потрібен React Native розробник, щоб разом перевернути цифровий світ! Ми працюємо по-сучасному й активно використовуємо AI-асистентів (Claude Code, Codex та подібних) у щоденній розробці — тож якщо ти з ними на "ти", тобі точно сюди. Готовий/готова до творчої свободи, сміливих ідей та смішних мемів у чаті? Тоді це твоя вакансія!

🌈 Як ми працюємо?

Формат: Повна зайнятість + віддаленка (можна працювати навіть у піжамі з їжачками 🦔). Твоя свобода: Автономія на максимум! Ми віримо в тебе — ти сам/сама обираєш, як виконувати задачі. Ніякої рутини: Мікроменеджмент — це не про нас. Твої ідеї впливатимуть на продукт одразу ж! AI-first: AI-інструменти — частина нашого щоденного флоу, і ми заохочуємо використовувати їх на повну.

🛠️ Що робитимемо разом?

Твій магічний посох (aka клавіатура) допоможе: Створити онбординг, календар, ленту та нотатки — усе, щоб користувачі сказали «Вау!». Інтегрувати API від бекенду (вони класні, обіцяємо!). Анімувати інтерфейс так, щоб він «жив» (навіть кнопки будуть посміхатися 😉). Випускати додаток в App Store та Google Play — хоч раз на місяць, як новий трек у Spotify! Брейнштормити з командою (наша фішка: кава + печиво + геніальні ідеї).

🧙‍♂️ Твої суперсили:

Досвід: 3+ роки в мобільній розробці, з них 1.5−2 — з React Native. Технічні чари: TypeScript, Redux, Formik — знаєш, як з ними дружити. Архітектурне бачення: Розумієш, чому iOS і Android іноді сперечаються, як діти. Продуктове мислення: Пропонуєш ідеї, навіть коли п'єш сік. Самодостатність: Вмієш приймати рішення, як капітан корабля. AI-магія: Активно використовуєш AI-асистентів у розробці — генеруєш код, рефакториш, ловиш баги і пишеш тести вдвічі швидше.

🎉 Бонусні очки, якщо ти:

Знаєш React.js (дві технології — дві суперсили!). Розумієш, як працює бекенд (ми частуємо цукерками за це 🍬). Говориш англійською на рівні «I can explain this meme».

🎁 Чому з нами круто?

Ти — архітектор: Впливай на продукт і технічні рішення прямо зараз. Команда мрії: Ми як піцца — різні, але разом ідеальні. 🍕 ЗП: Конкурентна, без затримок (бо ми знаємо, що Netflix сам не оплатиться). Ріст: Вчимось, помиляємось, сміємось і ростемо разом з продуктом!

📩 Як приєднатися?

Надсилай резюме, додай пару рядків про себе і покажи нам, чому саме ти — наш/наша ідеальний React Native маг!

About 4goo

We're building a social network for web and mobile — think rich user profiles, real-time messaging,
media feeds, and the scale that comes with it. Our backend is Go microservices on Kubernetes, and
every contract between backend and clients is formalised: OpenAPI for HTTP, AsyncAPI for the
realtime layer.

We're building our entire client layer from scratch — web, iOS and Android — as one monorepo owned
by one team. The first commit hasn't been written yet. We haven't launched publicly, the design
system is finished in Figma and being exported to code, and the architecture is completely open.

You'd be the person who decides it.

The Role

You own the client architecture across all three platforms, and you still write code every day —
this is not a role where programming stops.

Next.js on web, Expo on iOS and Android, one monorepo. Most of the UI is written once through a
universal component layer and rendered on both — which is the interesting part and the risky part.
Choosing that layer, deciding where the platform escape hatches go, and keeping the shared path from
degrading into lowest-common-denominator UI is your call and your problem.

The design system isn't something you'll invent. It's finished in Figma, with composition rules, and
it's exported to code — tokens and components generated rather than hand-copied, surfaced in
Storybook. Owning and extending that pipeline is central to the role.

You're the first hire on this team. The patterns you set are what everything else gets built on, and
you'll grow the team from here with real input on who joins.

You'll work with the architect and the backend teams as a peer. The contracts are the boundary
between us — you'll design against them, push back on them, and negotiate changes rather than accept
them passively.

What You'll Work On

- The universal UI layer. Write once, render on Next.js and Expo. Picking the approach, defining
 the escape hatches, and making sure "shared" doesn't quietly become "worse on both" is the
 highest-stakes work on this list.
- The Figma-to-code pipeline. The design system is complete in Figma with composition rules, and
 it's generated into code rather than hand-copied. Keeping generation, Storybook and the running
 apps in sync is ongoing engineering, not a one-off script.
- Contract-first on both surfaces. OpenAPI for HTTP, AsyncAPI for realtime messaging and in-app
 notifications — both generating typed clients that the whole monorepo consumes.
- The session model. Next.js can hold httpOnly cookies; native can't. Secure storage on device,
 token rotation, OAuth through deep links — one coherent model across three platforms, designed
 once and designed correctly.
- The release pipeline. EAS build and submit for native, web deploys, an OTA policy that's
 deliberate rather than accidental, and three platforms on one cadence.
- The decisions still open — see the Stack section. Those are yours.
- The quality bar that keeps "fast" from costing "right." We want to move quickly. That only
 works if the guardrails are real.
- Growing the team — hiring, review culture, and owning how this team works with AI.

What We're Looking For

Must have:

- 7+ years building client applications, including owning the architecture of a product that reached
 real users
- Both sides of the stack, not just one: React Native shipped to the app stores, *and* React on the
 web in production
- Deep TypeScript, and deep React
- You've built or owned a design system that more than one application consumed — and know why the
 second consumer is what breaks it
- You've reasoned about cross-platform code sharing before and can defend a position on it
- You take responsibility by default. You see the gap, you name it, you close it or find who can.
 There's no queue of tickets waiting for you and there won't be one
- You think in products. Architecture serves shipping; "correct" and "shippable now" are sometimes
 different answers, and knowing which one the moment calls for is most of the job

Strong plus:

- Universal / cross-platform UI layers — Tamagui, react-strict-dom, Unistyles or similar
- Storybook used as a real workbench, not a screenshot gallery
- Figma token pipelines, Code Connect, or generated component systems
- Next.js in production — rendering strategy, routing, and where its abstractions cost you
- Expo and EAS in production, including OTA updates
- AsyncAPI or other schema-first event contracts
- Monorepo tooling at a scale where it starts to hurt
- Real-time at scale — reconnection, ordering, backpressure, presence
- Video-heavy or feed-heavy consumer products
- Native modules and Expo config plugins — knowing where the managed workflow ends
- You've hired and grown a team before

Working With AI Agents

We build with AI agents deliberately, and at this level we expect fluency rather than familiarity.

The reason is specific rather than fashionable. The design system is finished. The backend contracts
are fixed and machine-readable. The team is small on purpose. So our constraint isn't figuring out
what to build — it's implementation throughput at a quality bar, which is exactly where agents pay
off and exactly where careless use gets expensive.

So: you know how to structure a repository so agents work well in it, how to scope work so the
output can actually be verified, how to review generated code seriously, and where the leverage
stops. Not "I've tried Copilot."

You'd also own how the rest of the team works this way — the conventions, the guardrails, the review
standards. If you have strong opinions here, lead with them. We're building this way on purpose, and
we'd rather argue about the details with someone who has thought about it.

What Good Looks Like in This Role

In your first month the foundations exist and they're demonstrated rather than described: the shape
of the monorepo, the universal UI approach proven on real screens on both platforms, and the
generated design system landing in Storybook.

Six months in, three platforms ship from one repository on one cadence. The standards are real
rather than aspirational, and delivery didn't stall while you made them so. Decisions are written
down and can be pointed at. And the people joining the team are people you chose.

 

Stack

Decided: React · Next.js · React Native · Expo (EAS) · TypeScript · monorepo · Storybook ·
OpenAPI + AsyncAPI generated clients · WebSockets · GitLab CI

Yours to choose: the universal UI approach · data and caching layer · monorepo tooling ·
testing strategy

Backend is Go microservices on AWS — you won't write it, but you'll negotiate contracts with the
people who do.

 

Interview Process

1. Intro call — what you've owned, and what you'd want to own here.
2. Architecture conversation on the real decisions in front of this team, including the ones we've
  already made. We're interested in how you reason, not whether you agree with us.
3. Offer.

 

What We Offer

- A codebase you start rather than inherit — the first commit is yours
- Architectural authority, given early, and expected to be used
- Real input on who joins the team next
- A small team by design, not by circumstance
- Direct access to decision-makers — no layers between you and the people setting direction
- Remote-friendly, async-first culture
- Competitive compensation based on experience

*In your application, tell us about a technical decision you got wrong and what you did about it.
That's the answer we read first.*
