Staff Solana Program Engineer

Who We Are Our client is a software development company that builds and operates the entire technology stack behind one of the largest consumer crypto platforms in production today. The systems are low latency, high throughput, live under constant load, and break if you get them wrong. What You Will Do You will design, build and maintain on chain programs that operate under heavy real world load. This is a hands on role with real ownership and immediate impact. Design and implement high performance Solana programs in Rust that handle significant transaction volume Reason carefully about program correctness, security and upgradeability in a production environment Optimise compute usage, account layouts and transaction flows for latency and throughput Work closely with backend and frontend engineers to design clean on chain and off chain boundaries Debug, test and ship changes that go live quickly and are used by hundreds of thousands of users Participate in design discussions around protocol changes, economic mechanics and system constraints Own programs end to end, from design and implementation through deployment, monitoring and iteration Who You Are Highly experienced engineer who has deployed production smart contracts or on chain programs that operate at meaningful scale, with real users, sustained volume and operational constraints Understands that building at scale is different from deploying isolated contracts, having dealt with performance bottlenecks, edge cases and real world failure modes Thoughtful about security, adversarial environments and long term maintainability Able to work independently, take ownership and make sound technical decisions with incomplete information Motivated by operating real systems at scale What It Is Like to Work Here The team works in person Hours can be long and unconventional The pace is intense Expectations are high, and impact is immediate This environment is not for everyone Why Join Unmatched ownership and autonomy Exposure to systems operating at the edge of crypto scale The ability to ship fast and see real world impact immediately
