Responsibilities
Lead design, implementation, and scaling of backend infrastructure and services, primarily in Go
Ensure backend systems are resilient, observable, and performant under high customer load
Drive architectural decisions for long-term scalability and maintainability
Contribute significant code to core backend systems, focusing on efficiency, robustness, and developer velocity
Establish and promote engineering best practices across the backend team
Collaborate closely with product, ML, and frontend teams to deliver high-quality features
Mentor and support other engineers, fostering growth and knowledge sharing
Qualification
Required
Proven track record turning ambiguous problem statements into shipped, reliable backend systems, owning work end-to-end from design through production
Significant expertise in Go, with deep knowledge of performance optimization, concurrency, and distributed systems
Experience running services at scale (thousands to millions of requests per second), anticipating scalability, reliability and downstream system impact
Strong background in service-oriented architecture, microservices, and API design, with a systems-level view of lifecycle costs and long-term maintainability
Proficiency with containerization and orchestration (Docker, Kubernetes)
Hands-on experience designing observable and operable systems, using metrics, logs, traces, testing, and alerts to detect and diagnose issues early. (Datadog, Prometheus, OpenTelemetry, etc.)
Experience with databases (SQL and NoSQL) and designing data-intensive systems
Hands-on experience stepping outside core backend ownership into one or more of infrastructure (cloud, IaC), ML systems (Python), or frontend (React) to solve integration problems, unblock teams, and directly implement features end-to-end when that is the fastest path to impact
Team first, low ego. Optimizes for team and company outcomes over individual wins; challenges ideas with data and reasoning, shares context early, and commits fully once decisions are made
Strong sense of ownership; takes responsibility for outcomes, not just tasks, acts with urgency without waiting to be asked, and leaves systems better than they found them
Bias to action and learning; ships frequently, tests high-impact assumptions early, and uses small, safe-to-fail experiments to learn from real feedback
Customer-impact focused; cares deeply about how reliability, latency, and correctness shape real-world user outcomes and trust
Intrinsically motivated; maintains momentum without external pressure and pushes work through ambiguity to real outcomes
Curious and continuously learning; seeks deep understanding of the product, systems, and users, and challenges assumptions in pursuit of better results
