Staff Backend Engineer, Gatekeeper

We're looking for a Staff Backend Engineer to own and evolve Gatekeeper, Helius’s high-performance edge gateway and middleware layer. Gatekeeper is the single entry point for JSON-RPC, WebSockets, and Helius APIs, and it exists to make latency and reliability feel comparable to running a dedicated node, globally.

Requirements

• Significant experience building and operating high-throughput backend systems in production (proxies, gateways, distributed services, or infra-heavy platforms).
• Deep understanding of networking fundamentals and HTTP behavior (TLS, TCP, connection reuse, proxies, load balancers, timeouts).
• Strong performance engineering skillset: profiling, benchmarking, and making latency/throughput tradeoffs with rigor.

Benefits

• Market-leading salary
• Meaningful equity
• Generous vacation
• Wellness budgets
• Support for learning and travel
