Senior/Lead Smart Contract Engineer - Decentralized Perpetuals Exchange

Location: Remote - US or EU if willing to overlap 6+ hours with ET

Compensation: $250K - $500K

We are building the backbone of global decentralized finance (DeFi), operating the largest perpetual exchange on Arbitrum and processing over $20 billion in cumulative trading volume. Our platform enables leveraged trading of real-world assets (RWAs)—commodities, forex, indices, and stocks—alongside crypto, bringing global markets on-chain with full self-custody. Backed by General Catalyst and Susquehanna International Group, we are a small team providing institutional-grade reliability for a protocol handling billions in volume.

We are seeking an exceptional Senior or Lead Smart Contract Engineer to help scale our protocol as we expand to hundreds of markets and billions in daily volume. You will work directly with our founding team (backgrounds from Harvard, Bridgewater, and BlackRock) to architect and implement critical protocol upgrades and new market mechanisms for the next generation of on-chain derivatives.

This is not a junior role. We need an expert who has built and maintained perpetual Decentralized Exchange (DEX) smart contracts in production at scale.
