Backend Software Engineer

• Deep fluency in at least one backend language (TypeScript/Node.js, Go, Python, or Java) — we use TypeScript heavily but value polyglot thinkers • Hands-on experience with PostgreSQL (query optimization, indexing strategies, schema migrations) and Redis (caching patterns, pub/sub, rate limiting) • Familiarity with message broker patterns — RabbitMQ preferred, but Kafka or NATS experience translates well • Solid understanding of distributed systems fundamentals: consistency models, failure modes, backpressure, idempotency • Experience with Kubernetes in production — not just deploying, but debugging networking issues, resource contention, and pod lifecycle surprises • Strong debugging instincts: you're the kind of engineer who reaches for tcpdump or strace before restarting the service • Experience with event-driven architectures or CQRS patterns • Familiarity with Temporal.io or similar workflow orchestration frameworks • Background in transit, logistics, or any domain where latency directly impacts a physical-world experience • Experience operating multi-tenant or multi-site deployments • You've written a runbook that actually saved someone at 2am
