Description

About the company Our client is a Web3 development studio focused on decentralized trading products and tools for the DeFi community. Already generating 7-figure ARR, the company continues to grow rapidly — expanding into new features and market opportunities. The team works with fast iteration, hackathon-level energy, and full ownership of the products they build — a small, high-impact group where every engineer has a visible impact. Location & work mode Hybrid: we spend ~6–7 months per year in Dubai and the rest in Europe. Travel and lodging during on-site periods are covered by the company. Remote from Europe is possible for exceptional engineers able to join us in Dubai for a few months per year. Compensation Competitive package (crypto preferred) + stock options / equity with planned reviews. We focus on long-term partnerships, not short-term gigs. What you’ll do Build and scale decentralized trading products — from web trading interfaces to Telegram trading bots and backend systems. Design and implement backend services & APIs for on-chain execution, routing, pricing, and risk logic. Work with smart contracts (Solidity) and on-chain data (indexing, explorers, mempool/tx decoding). Own the entire lifecycle: specification → implementation → deployment → monitoring → iteration. Touch the frontend (React/Next.js) enough to ship end-to-end. Handle pragmatic infrastructure work: deployments, debugging, performance tuning, reliability. Contribute to product thinking — shaping features and prioritizing impact. You are A Swiss-knife engineer — comfortable switching between backend, frontend, infra, and on-chain work. Deep on fundamentals: data structures, scalability, performance, reliability, security mindset. Autonomous and fast-moving — no need for micro-management. Startup-ready: prefer shipping over bureaucracy, communicate clearly, and take ownership. Our client values exceptional ability over years of experience - they welcome both Strong-Middle and Senior engineers, as long as the technical depth is genuine. Must-have Solid backend experience with TypeScript/Node.js, Python, Go, or Rust. Strong API design, data modeling, testing, and production debugging skills. Experience delivering in high-load or fast-paced environments (crypto, trading, or startups). Confident with databases (PostgreSQL or similar) handling large, fast-growing datasets. Hands-on DevOps mindset - containers, CI/CD, observability, deployments. Fluent English; French is a major plus. Nice to have DeFi/Web3 background - Solidity, Ethers.js/Web3.js, DEXs, perps, launchpads, or on-chain analytics. Experience in trading systems (pricing, execution, routing, risk). React / Next.js front-end experience. Knowledge of AWS (ECS/EKS, S3, IAM), Grafana / Prometheus / Datadog / Sentry. Work with data pipelines for large blockchain datasets. Security awareness - keys, permissions, anti-MEV, safe deployments. Why this role Impact & ownership: small senior team, direct collaboration with CEO & CTO. Strong upside: competitive pay + equity. Innovation space: decentralized trading, multi-chain indexing, real user scale. Lifestyle: mix of Europe & Dubai, travel and lodging fully covered during on-site months. Hiring process Pre-screen call (30 min) with recruiter - discussing your background, motivation, and technical breadth. Profile review by CTO. Intro call with CEO (5–10 min). Technical interview with CTO - live discussion based on your real work (no take-home tests unless you prefer one).
