Design, build, secure, and optimize Rust-based Solana programs for perpetual futures markets, including trading, margin, liquidations, settlement, oracle integrations, and cross-program interactions. Develop tests, support audits, manage upgrades and migrations, investigate production incidents, and contribute to multi-chain protocol architecture while collaborating with trading, risk, product, and protocol teams.
We are building high-performance perpetual swap markets on Solana and need a senior smart-contract engineer to help bring them on-chain. You will design, build, and harden Rust-based Solana programs for trading, margin, liquidations, and cross-program integrations—where correctness, security, and compute efficiency are core product requirements.
You will work closely with protocol, trading, risk, and product teams to shape the architecture of a multi-chain derivatives protocol. This is a hands-on role for an engineer who has shipped production Solana programs and enjoys working at the intersection of markets, systems performance, and protocol security.
What you’ll do
- Design and implement Solana programs for perpetual futures markets, including positions, collateral, margining, funding, liquidations, and settlement.
- Build secure and efficient on-chain logic for order handling, position updates, risk checks, and liquidation flows.
- Optimize account layouts, instruction design, and compute-unit consumption for high-throughput trading.
- Integrate price oracles and design safe cross-program invocation (CPI) boundaries, account validation, and privilege controls.
- Write comprehensive unit, integration, and fork tests; support third-party security audits and remediate findings.
- Contribute to protocol architecture across Solana and other chains, including upgradeability, migrations, and cross-chain design considerations.
- Collaborate with product and trading teams to translate market mechanics into precise, testable on-chain specifications.
- Monitor production programs, investigate incidents, and continuously improve operational safety and performance.
What we’re looking for
- 4+ years of software engineering experience, with 2+ years building and shipping Solana programs.
- Strong Rust skills and hands-on experience with Anchor.
- Deep understanding of the Solana account model, PDAs, rent, account ownership, transaction atomicity, and compute limits.
- Experience shipping Solana programs to mainnet, including upgrades, migrations, and production incident response.
- A security-first mindset: threat modeling, least privilege, invariant testing, and careful handling of external inputs and CPIs.
- Experience with testing frameworks, local validators, program simulations, and audit workflows.
- Strong communication skills and comfort operating in a remote, fast-moving team.
Nice to have
- Experience building on-chain order books, AMMs, or perpetual futures protocols on Solana.
- Experience writing native, non-Anchor Solana programs.
- Familiarity with oracle integrations, margin/liquidation systems, or decentralized exchange architecture.
- Contributions to Solana open-source projects or prior security-audit experience.
- Experience with multi-chain protocol design, cross-chain messaging, or interoperability.
