Jobs at Djinni

We're Gypsy Collective. The digital world is evolving faster than ever. New opportunities, new challenges, new ambitious goals. That’s why strong businesses need strong people. 

Gypsy Collective is an exclusive talent partner for selected brands. We help our partners attract exceptional talent by building long-term relationships and becoming deeply integrated into their business, culture, and growth ambitions.

Now we're looking for someone to lead our affiliate channel into its next frontier.

If you've built affiliate pipelines from scratch, know how to close a CPA deal in your sleep, and can smell low-quality traffic before it hits the dashboard — keep reading.

Your expedition

As Head of Affiliates, you own the entire affiliate channel — strategy, team, deals, traffic quality, and results. You're not here to manage a spreadsheet. You're here to build a machine.

📅 Your adventures include:

• tier-1 GEO experience: hands-on experience with Tier-1 markets, traffic quality, partner expectations, competition, and scaling logic;
• deal-making: ability to negotiate, close, test, and scale CPA / RevShare / Hybrid deals;
• affiliate acquisition: ability to find and onboard strong affiliates through networks, events, tools, forums, social media, CRM, and direct outreach;
• traffic & profitability analysis: strong understanding of FTD, profit, conversion, retention quality, ROI, caps, reconciliations, and traffic scaling;
• team management: experience leading affiliate managers, setting KPIs, reviewing pipelines, tracking performance, and holding the team accountable;
• deal funnel ownership: ability to manage partner flow from lead → negotiation → approval → test cap → scale / reject;
• risk & fraud control: ability to detect low-quality traffic, fraud signals, suspicious patterns, and compliance risks;
• reporting discipline: ability to provide clear updates on FTD, profit, partner pipeline, traffic quality, risks, and next steps;
• strong negotiation skills: payout deductions, price adjustments, cap / deal terms renegotiation.

🧭 What makes you a great match:

• 3+ years of hands-on experience in affiliate marketing or campaign management (iGaming preferred);
• 2+ years in a team lead or head-of role — managing people, pipelines, and performance;
• lead and develop a team of affiliate managers: set KPIs, review pipelines, track performance, and keep everyone moving in the right direction;
• own the full deal funnel — from lead to negotiation to approval to test cap to scale or cut;
• find and onboard strong affiliates through networks, events, forums, social media, and direct outreach;
• negotiate, close, and renegotiate CPA / RevShare / Hybrid deals — including payouts, caps, and terms;
• dive deep into FTD, profit, conversion, retention quality, ROI, and reconciliations to make fast, confident calls;
• detect fraud signals, suspicious traffic patterns, and compliance risks before they become problems;
• deliver clear, structured reporting on partner pipeline, traffic quality, risks, and next steps — no fluff.

First design hire at NewArc. Own how every screen looks and feels — fluent in both Figma (or similar) and the web platform we ship.

1. Requirements and nice-to-haves

Hard requirements

• Senior product / UI / UX design skill. 5+ years of experience. You can take a feature from a kick-off discussion to a complete, ready-to-build design — every screen, every transition, every empty / loading / error state — and make the calls on what it looks like, how it feels, where everything goes.
• Web-platform fluency. You read and compose HTML and CSS (we use Tailwind) without help. You are comfortable in a real codebase — opening files, editing JSX or templates, running a dev server, seeing your change in the browser. You do not need to be an engineer; you need to be a designer who lives in the div-and-tag layer rather than in Figma alone.
• Evidence of prior shipped product work. We want to see features that real users use, with you describing your role in shipping them — not Figma case-study mock-ups, not concept reels.
• Strong written and spoken English. The team works in English end-to-end.
• Time zone overlap. At least four hours of daily working-time overlap with London.

Nice-to-haves

• Fluency with AI-assisted coding tools. Cursor, Claude Code, Codex, Lovable, v0, Bolt, or similar.
• A public footprint in the design-engineer orbit. Public contributions, a browsable interactive portfolio, etc. We notice this.
• Experience shipping inside a small team where everyone wears multiple hats.
• Background in, or genuine interest in, the fashion industry. Apparel, footwear, accessories, eyewear — the brand, e-commerce, or marketplace side. Most of the customers we ship for live in this world.
• Some marketing-adjacent skill. Landing pages, brand surfaces, conversion writing. We are small enough that wearing a marketing hat occasionally is a real plus, but a great product designer who is mostly incompetent at marketing is fine too.
• Product management. Thinking about the backlog systematically based on strategic direction, customer feedback, and continuously calibrated gut feeling.

2. About the company

Founded in 2022, NewArc empowers thousands of product/apparel/footwear/accessories designers across industries with cutting-edge AI so they can ship fantastic products faster and cheaper. We work with individual designers as well as the largest companies in the fashion industry.

Internally, we are just a small group of folks enjoying their craft. We are all professional and hands-on. We also play vibe-coded Bomberman at daily stand-ups.

We enjoy deep work, lean processes, and having fun.

We don't live at work. We do our very best within work hours and move on to living the rest of our lives.

3. What we offer

• Competitive salary. Full-time employment. Remote.
• Direct work with the two co-founders and the product team. The team is small and high-trust. We try to keep process out of our way as much as possible. Discuss, ship, iterate, repeat. No middle management — everybody is hands-on.
• Role evolution. We are AI-first in ways that are actually productive. AI has already been reshaping every role on the team. A year from now, the Product Designer role will mean something different from what it means today. We will help you stay on the edge of that transition.
• Growth. You are our first hire in Design. As we grow, you will naturally have opportunities to broaden your area of responsibility towards leadership or product ownership.
• Immediate connection. What you design in the morning might be used by thousands of people in the evening. There's no one standing between you and the product.

Selection process

1. Screening call — 30 minutes.
2. Technical call — around two hours.
3. Founder call — up to an hour.
4. Paid work trial — multi-day, on a real upcoming feature, against the live repo. Simulating the real work as much as possible.
5. Final decision

How to apply

Send:

• CV
• (optional) Cover letter
• Anything that would serve as the best evidence of your product / UI / UX design skill
• Anything that would serve as the best evidence of your Web / HTML / CSS experience

We are building a talent pool of Web3 Frontend Developers for upcoming outstaff projects with international clients 🚀.
 

This is part of our candidate pipeline — there is no specific project at the moment, but once a suitable opportunity becomes available, you'll be matched based on your skills and experience.
 

We're looking for frontend developers who can build dApp interfaces for EVM and Solana products — from wallet connections and transaction flows to DeFi dashboards and protocol UIs.

 

🛠️ Key Responsibilities
 

🔹 Build dApp interfaces using React / Next.js

🔹 Integrate wallets using wagmi, WalletConnect, and wallet adapter libraries

🔹 Work with viem / ethers.js for on-chain reads and writes (EVM)

🔹 Handle async blockchain state with React Query / TanStack Query

🔹 Manage application state using Redux or Zustand

🔹 Build intuitive, reliable UIs for DeFi, NFT, and protocol products

🔹 Collaborate closely with smart contract and backend developers

🔹 Communicate directly with international clients in English

 

📋 Requirements
 

🔹 2+ years of commercial experience with React / Next.js

🔹 Hands-on experience building dApp interfaces (wallet connect, on-chain data, transactions)

🔹 Solid knowledge of wagmi and WalletConnect integration

🔹 Proficiency with React Query / TanStack Query

🔹 Experience with Redux or Zustand

🔹 Understanding of EVM basics (transactions, gas, contract reads/writes)

🔹 Experience with real-time UI reactivity — seamless UI updates after on-chain actions (optimistic updates, event subscriptions, polling)

🔹 Basic understanding of the Solana ecosystem (accounts, transactions, wallet model)

🔹 English: B2+

🔹 Ability to work independently

✨ Nice-to-Haves

🔹 Experience building Solana dApp interfaces (wallet adapter, on-chain reads, transaction flows)

🔹 Understanding of DeFi UX patterns (slippage, gas estimation, token approval flows)

🔹 Experience with TypeScript in large-scale production React codebases

🔹 Exposure to NFT marketplace or on-chain gaming UI

🌱 Why Join Our Talent Pool?

🔹 Real dApp Engineering — interfaces for real users and real protocols

🔹 International Clients — teams across Europe and North America

🔹 Remote & Flexible — outstaff format, async-friendly

🔹 Blockchain-First Team — we speak the same language

🔹 Fast Matching — when the right project appears, we move quickly

✨ Why This Is a Great Opportunity

🔹 Real-world exposure — every project is different: different chains, different protocols, different challenges

🔹 Outstaff done right — we stay involved, support you throughout the engagement, and match you only where your stack truly fits

🔹 Keep growing — instead of running out of things to do at one company, you move to the next challenge

📬 What Happens After You Apply

🔹 Our team reviews your profile within a few business days

🔹 If there's a good fit, we'll schedule a brief intro call — to learn about your background, stack, and what you're looking for

🔹 After the call, you'll join our talent pool and we'll reach out proactively once a matching project comes up

⚠️ Important

🔹 This is a talent pool position (pipeline)

🔹 No specific project at this moment

🔹 You'll be contacted once a suitable opportunity becomes available
