About Mangrove

Mangrove is a next-generation order book DEX where liquidity providers can post programmable offers. By linking arbitrary smart contracts to liquidity, Mangrove opens up a novel design space for DeFi infrastructure and composability. We’re backed by top investors in the space and value expertise, creativity, autonomy, and deep technical curiosity.

We are looking for a Fullstack Blockchain Developer to join our core engineering team. The role is full-time, ideally based in Paris, but remote-friendly for the right candidate.

• Design and maintain backend services (Node.js/TypeScript) supporting complex trading logic
• Collaborate with smart contract engineers to bridge protocol mechanics with user-facing tools
• Develop and implement new strategies based on research insights
• Contribute to Mangrove’s technical and product direction
• Scale, monitor, test, and optimize production systems in a fast-paced DeFi environment

Requirements

• Solid full-stack Web3 dev (frontend + backend)
• DeFi and crypto power user, eager to learn
• Expert in React, TypeScript, and modern frameworks
• Skilled with EVM contracts using ethers.js, wagmi, or viem
• Experience with Hono, Ponder, and on-chain data indexing
• Built and shipped live DeFi products with real users
• Clean, tested code; autonomous and fast-paced mindset
• Fluent in English and partially available during CET hours

Nice to have

• Experience with smart contract development (Solidity)
• Passion for DeFi, trading, or low-level protocol design

What does Mangrove offer?

• Competitive salary + equity/tokens
• High-impact, full-ownership role
• Full autonomy to build and ship
• Work with a top-tier team, including PhDs and DeFi veterans
• Team retreats and conferences
• Shape the future of on-chain trading
