Job 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.
