Job description

We’re building high-performance on-chain infrastructure on Solana — and we’re looking for a top-tier Rust engineer who has already shipped production smart contracts.

What You’ll Do

• Design, build, and deploy production-grade Solana programs (SVM)
• Optimize for performance, compute efficiency, and security
• Write clean, auditable Rust with long-term maintainability in mind
• Lead contract design decisions from first principles
• Work closely with backend + frontend engineers to ship fully integrated systems
• Review, refactor, and harden existing contracts
• Prepare codebases for external audits

You Must Have

• Deep expertise in Rust
• Strong experience with Solana (Anchor + native programs)
• Shipped at least one production protocol or smart contract system
• Experience handling:
• PDAs
• CPI calls
• Account serialization
• Compute optimization
• Security patterns
• Solid understanding of:
• DeFi mechanics
• Experience debugging mainnet issues under pressure

Bonus Points

• Built or contributed to:
• DEXs
• Perps protocols
• MEV-aware systems
• High-frequency trading infra
• Experience with security audits
• Knowledge of validator architecture / RPC optimization
• Performance tuning at the byte level

What We Care About

• You think from first principles
• You optimize for speed + security
• You’ve seen what fails in production
• You move fast without breaking core logic
• You want to build category-defining infrastructure
• High-performance startup
• Remote, async, execution-driven
• Small team, high ownership
• Direct impact on core protocol architecture
