Read our **Helius Manifesto** to see how we work and what we value. --- ## About the Role 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. In this role, you will lead architectural decisions across routing, connection management, backpressure, and observability. You will work closely with internal service teams to improve end-to-end performance and failure handling, and to make Gatekeeper safer to operate at high scale. --- ## About the Team The Gatekeeper team builds and operates the edge layer that sits in front of Helius's backend infrastructure. The team is performance obsessed and deeply operational: we ship systems that run globally, handle high request volumes, and must remain reliable under load and during incidents. We collaborate tightly with infrastructure and service owners to ensure Gatekeeper is a force multiplier for the whole platform, not just a proxy. --- ## What You'll Do - 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. --- ## What We're Looking For - 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. - Track record of leading ambiguous, cross-team projects and shipping durable systems. - Operational excellence: you have owned services with real on-call responsibility, and you make them easier to run over time. - Excellent communication: you can write clear design docs, align stakeholders, and make decisions legible. --- ## Nice to Have - Rust experience (or strong interest in working close to the metal for performance-critical systems). - Experience with anycast, multi-region traffic management, or edge deployments. - Familiarity with WebSockets at scale and the operational challenges that come with long-lived connections. - Experience building internal platforms that standardize observability, incident response, and service reliability. - Interest in Solana / crypto infrastructure, market data, or latency-sensitive trading systems. --- ## Why Helius? - **High-impact work:** Your code will power applications used by millions across the Solana ecosystem, including Coinbase, Jupiter, and Phantom. - **Serious engineering:** Build fast, reliable systems and user experiences across distributed infra, high-throughput backends, and modern frontend stacks. - **Ownership & growth:** Lead critical initiatives, influence architecture and product direction, and take on more responsibility as the company scales. - **Remote-first flexibility:** Work where you're most effective with a flexible, fully distributed team. - **Competitive comp & perks:** Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel. - **Mission-driven team:** Join ambitious builders who move fast, take ownership, and are shaping the future of decentralized apps. --- *When applying, mention the word **CANDYSHOP** to show you read the job post completely.*
