Backend Engineer

• Lead the technical direction for Gatekeeper as the unified entry point for Helius traffic, with an emphasis on p50/p99 latency and tail reliability.
• Design and implement routing and load balancing strategies across regions and backend pools, including failover behavior and graceful degradation.
• Improve connection handling end-to-end: TLS termination, keepalives, pooling, timeouts, backpressure, and request/response streaming behavior.
• Build robust, operator-friendly observability: SLOs, dashboards, alerts, and “is it healthy?” views that make issues diagnosable fast.
• Partner with internal service teams to define and enforce contracts (timeouts, retries, error mapping, capacity signals), and reduce systemic failure modes.
• Drive hardening work across security and abuse controls (auth failure behavior, rate limiting / caps enforcement, request validation).
• Own production operations for Gatekeeper: incident response, on-call improvements, runbooks, and post-incident follow-through.
• Mentor engineers and raise the bar on performance engineering, operational rigor, and code quality.
