Blockchain Data Engineer - Real-time DeFi Infrastructure - CDI/Freelancer

Location: Paris 13th (Station F)
Start: Flexible (From September 2025)
Duration: Full-time (CDI) or project-based (Freelance)

Introduction to the Ecosystem

Are you ready to tackle one of the most fundamental problems in decentralized finance? The rise of concentrated liquidity pools like Uniswap v3 has brought unprecedented efficiency to DeFi, but it has also introduced significant complexity and risks for liquidity providers—impermanent loss being a major challenge.

At Lobster, we are on a mission to revolutionize liquidity management in decentralized exchanges. Our groundbreaking strategy neutralizes exposure to one of the assets in a liquidity pool, enabling delta-neutral liquidity provision that protects capital while maintaining efficiency.

We're not just building another DeFi protocol; we're solving a core challenge in the ecosystem with innovative solutions that redefine on-chain liquidity standards. After three years of intensive research and development, our strategies and models have been tested and proven to reduce risk, improve capital efficiency, and scale in collaboration with top decentralized exchanges (DEXs).

This is your opportunity to join a founding team with a strong reputation in the Web3 ecosystem. With trusted partners and cutting-edge solutions, we're building the next evolution of DeFi. Let's redefine decentralized finance—together. 🦞

Why Lobster?

Decentralized finance has grown exponentially in recent years, but the complexity it introduces for investors and liquidity providers remains a significant barrier. At Lobster, we've developed mathematical models and autonomous strategies that eliminate impermanent loss and enable delta-neutral liquidity provision.

Our protocol addresses real pain points in the DeFi space, empowering liquidity providers with tools to minimize risk and maximize efficiency. Joining Lobster means working alongside a team that is shaping the future of decentralized finance with solutions built to scale globally.
