Jobs at Djinni

I'm looking for an experienced developer for Gymlads.nl, a fitness coaching app built in Adalo. We're close to going live and I need someone who can set up the remaining technical pieces properly and thinks ahead.
 

I'm not just looking for someone to fix a few things. I'm looking for someone who wants to grow with the product long-term. After the launch I'm looking for an ongoing collaboration on an hourly basis.
 

Phase 1 — Tasks before go-live:

Task 1: Set up subscription management (RevenueCat + Adalo + Supbase)

Currently the app has a payment page via RevenueCat, but there's no working connection between who pays and the user in Adalo. This needs to be fully set up. Specifically:

• When a user clicks "buy subscription", their user ID must automatically be passed to RevenueCat
• After a successful payment, the subscription must automatically be activated for that specific user in Adalo, without any manual step
• This must work for both purchases via the website and via the app store (iOS/Android)

The end result is that a user pays and immediately has access in the app, fully automatically.

Task 2: Forward onboarding data to Supabase

When a user completes the web onboarding flow, the relevant data must automatically be saved in Supabase. Think user ID, email address and subscription status. This will be set up via n8n or a direct API connection.

Task 3: Add a paywall in Adalo

A paywall needs to be added to the app. Users without an active subscription cannot access the premium content and are automatically redirected to the payment page.

Task 4: Distinguish between website and app store users

The app needs to recognize whether someone is coming from the website or from the app store. Users coming from the website are sent directly to a specific loading screen where the app generates everything automatically. Users coming from the app store go through the normal flow. This must work reliably every session.

Phase 2 — Ongoing collaboration:

After go-live I'm looking for someone for structural further development on an hourly basis. Think new features, improvements and AI integrations. I want someone who thinks ahead, builds things in a way that scales, and stays involved as the product grows.
 

What I'm looking for:

• You've built apps or backends before — show me something you've made, doesn't have to be for a big company
• You understand how API connections, webhooks and databases work and can set them up properly
• You know how to work with AI tools and can set up a proper integration when needed
• You build things with the future in mind, not just to get it done
• You communicate proactively and think along
• Experience with Adalo, Supabase, n8n or RevenueCat is a plus, but not required
   

How to apply:

Send a short explanation of how you would approach Task 1, and share something you've built before. Also include your hourly rate.

About the role

We're building a performance marketing team from scratch, and email is a core channel for retention, reactivation, and lifecycle communication. This role owns all email communication across the company — transactional, marketing, and campaign-based — and works at the intersection of marketing and product to create a seamless user experience across web and mobile.

Responsibilities

• Full ownership of the email channel: strategy, execution, and performance across all communication types (transactional, broadcast, campaign, lifecycle flows).
• Design, build, and optimize automated flows and trigger-based sequences across the full user lifecycle — from onboarding and activation through engagement, re-engagement, and win-back.
• Develop segmentation strategies based on user behavior, product usage signals, and audience attributes to increase relevance and channel efficiency.
• Run systematic A/B tests on subject lines, content, timing, frequency, and flow logic. Formulate hypotheses, execute tests, and implement learnings.
• Work with users that enter the funnel (e.g., blog subscribers, quiz completions) but don't convert — build nurture sequences to move them toward action without aggressive frequency, respecting the sensitive nature of the product.
• Collaborate closely with the product team to ensure email communication is aligned with what's happening in the product (web + app), reflects the brand's tone of voice, and functions as part of a unified system rather than a siloed channel.
• Collaborate with the communications team, designers, and copywriters on email content. This role is the owner and final decision-maker on what gets sent, when, and to whom.
• Own email content creation and ideation — propose new campaigns, communication angles, and lifecycle touchpoints.
• Manage deliverability: domain health, sender reputation, spam rate monitoring, list hygiene.
• Build and maintain regular reporting on channel performance — open rates, CTR, conversion, unsubscribe rates, revenue attribution per flow.

For discussion: Participate in designing churn prevention flows triggered by product usage signals (e.g., no session booked in X days). Email is a secondary channel here — the logic and triggers will be defined jointly with the product team, but execution in email sits with this role.

Requirements

• 3+ years of experience in email marketing in a product company (SaaS, marketplace, or subscription-based product/edtech).
• Hands-on experience building automated flows and trigger-based campaigns in a marketing automation platform (experience with Customer.io is a strong plus).
• Strong understanding of user lifecycle stages and how email fits into the broader marketing and product funnel.
• Understanding of event-based triggers and audience parameters — ability to think in terms of "if user did X and didn't do Y within Z days, then…"
• Experience with segmentation, personalization, and A/B testing at scale.
• Solid grasp of email deliverability fundamentals (domain authentication, warm-up, list hygiene, spam triggers).
• Analytical mindset — comfortable working with data, interpreting metrics, and making decisions based on test results.
• Attention to detail, ownership mentality, and ability to work autonomously.

Nice to have

• Experience in health, wellness, or mental health products.
• Understanding of sensitive product communication — where intensity ≠ quality and user trust is paramount.
• Experience working with cross-functional teams (product, design, content).
• Familiarity with analytics tools (Mixpanel, GA4, or similar).
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work - no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;
• Competitive compensation, based on your qualifications and experience;
• Paid time off 33 days per year (including public holidays);
• Paid sick leave 10 working days per year;
• Budget for learning and development;
• Paid mental health leave (5 working days per year).

About the role

We're building a performance marketing team, and this role is central to how we grow — owning conversion rates across all marketing touchpoints and the full user journey from first page view to first paid session. You'll work at the intersection of marketing, product, and engineering to generate, test, and scale ideas that move our core metrics: conversion rate, new clients, and CAC.

Responsibilities

• Own conversion performance across all marketing surfaces: main website, blog, landing pages, campaign funnels, and any new acquisition flows.
• Generate, prioritize, and execute CRO hypotheses — from ideation through briefing, prototyping, A/B testing, analysis, and implementation of winning variants.
• Design new funnels for paid channels (Meta, TikTok, and others as we scale), including concept, user flow, messaging framework, and success criteria. Coordinate execution with design, content, and engineering teams.
• Own the post-click experience for all paid traffic — ensure that what happens after a user clicks an ad is optimized for conversion, not just for traffic volume.
• Create and optimize landing pages for campaigns, audiences, and channels — working with designers and developers or using no-code/AI tools where appropriate.
• Monitor and analyze funnel performance at every stage (page view → authorization → first therapy created → first purchase). Identify drop-off points, diagnose root causes, and act on them.
• Run a continuous experimentation process: maintain a hypothesis backlog, manage test calendars, ensure statistical rigor, document results and learnings.
• Write clear briefs and technical specs for product and engineering teams. Communicate the goal, the hypothesis, the expected impact, and the success criteria for every initiative.
• Collaborate with the product team on the authorization-to-purchase flow. Currently owned by product — this role progressively takes over the marketing lens on this funnel, working jointly to improve it.
• Collaborate with the UA/paid channels manager on campaign-to-conversion alignment: ensuring ad creative messaging matches landing page experience, and that conversion signals are properly tracked.
• Participate in tracking and attribution setup alongside analytics — flag data gaps, validate conversion events, ensure the team can trust the numbers.
• Report regularly on conversion metrics, experiment results, and impact on new clients and CAC.

Requirements

• 3+ years in growth marketing, CRO, or a similar experimentation-driven role in a product company (marketplace, SaaS, subscription, or similar).
• Proven track record of improving conversion rates through systematic testing — not just ideas, but shipped experiments with measurable results.
• Strong understanding of user funnels, landing page best practices, and conversion psychology.
• Ability to write clear briefs, create wireframes or prototypes (even rough ones), and articulate what needs to be built and why.
• Hands-on experience with A/B testing tools (Google Optimize, VWO, Optimizely, or built-in product experimentation).
• Comfortable with analytics tools (GA4, Mixpanel, or similar) — able to pull data, interpret funnel reports, and make decisions based on evidence.
• Understanding of event-based tracking: how user events and parameters work, how they trigger flows, and what breaks when tracking is misconfigured.
• Strong cross-functional communication skills — this role lives between marketing, product and engineering daily.
• Structured thinking and ability to prioritize based on expected impact vs. effort.

Nice to have

• Experience with mental health, wellness, or other sensitive/high-trust products where aggressive conversion tactics don't work.
• Experience creating funnels for Meta Ads or other paid social channels specifically.
• Familiarity with no-code tools for landing pages
• Understanding of paid acquisition economics (CAC, LTV, ROAS) and how CRO improvements cascade into unit economics.
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work- no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;

• Paid time off 33 days per year (including public holidays);

You’ll be working on complex, real-time challenges at the core of our platform - improving latency, ensuring high availability, and making systems more efficient at scale. This is not a coordination-heavy role; it’s for someone who enjoys writing production code, solving tough engineering problems, and seeing the direct impact of their work.

If you’re product-driven, take ownership, and prefer a “build first, improve fast” approach while working on systems where every millisecond matters - this role will feel like home.

Key Responsibilities

• Work as part of a cross-functional team owning a core product within the platform
• Design, build, and deliver new backend features end-to-end in a distributed environment
• Write high-quality, production-level code daily, contributing directly to a high-load, scalable system

• Skilled in developing and maintaining end-to-end and unit tests
• Proven track record of developing production-ready solutions
• Degree in Computer Science or related field

• Understanding of application security and industry best practices
• Understanding of enterprise development patterns
• Active performance observation
• Gambling domain experience

What We Offer

• Competitive Salary: We offer a competitive salary, subject to annual performance reviews

4. Final Interview with C-level (60 mins)

PaperLink (paperlink.online) is a document sharing platform with view analytics. You send a client a document and see who opened it, which pages they read, and how long they spent on each. Plus invoicing, financial tracking, and AI integration with Claude via MCP. No competitor has MCP-based AI integration.

The product is live. We need someone who can sell it and build the revenue foundation for what comes next.

What you'll do

• Bring first paying clients from your existing network or outreach
• Build and own the sales process from scratch
• Define ICP, messaging, and channels that work
• Lay the foundation for a future sales team

Who we're looking for

Someone who has done this before. You've built revenue at an early-stage B2B SaaS. You know how to close, and you know how to build the system around closing.

Ideally you have existing contacts in the target market: freelancers, consultants, law firms, agencies, or SMBs that regularly share documents with clients.

Part-time is fine. You likely work with several projects simultaneously. That's expected.

Compensation

Commission-based with equity participation tied to MRR milestones.

Commission-based on clients you bring. Equity participation as the product grows. Salary kicks in once MRR hits a defined threshold. All terms agreed upfront.

Payments: monthly, method by agreement.

Why this might interest you

The product exists and works. Competitors charge $45-150/month. We have a free plan and a real technical advantage.

The market is large. Every freelancer, lawyer, and consultant sends documents to clients.

Early stage means real influence. You define how revenue is built here, not inherit someone else's playbook.

What not to expect

Fixed salary from day one. If you need immediate stability, this isn't the right position.

A team to manage yet. That comes later. Right now it's you and the founder.

Format

Remote. Part-time. Flexible schedule. Any time zone.
