Software Engineer - Founder Accelerator Infrastructure

Compensation: $180K - $260K

We are the leading accelerator for crypto founders, having backed over 300 startups that are now collectively valued at over $10 billion. We are a small, high-trust, high-performance team of builders (ex-Meta, YC, Coinbase, and founders) backed by S-tier investors. We are hiring a Software Engineer to join our in-house engineering team and own features from requirements definition through production launch.

Reporting directly to the CTO, you will be a product-minded, hands-on Individual Contributor who owns the delivery of core products end-to-end. This means turning ambiguous problems into high-quality, shipped software that directly accelerates the next generation of top crypto and AI founders.

What you’ll do:

Senior/Lead Smart Contract Engineer - Decentralized Perpetuals Exchange

Compensation: $250K - $500K

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.
