SeniorSiteReliabilityEngineer

ABOUT TRIGGER.DEV Trigger.dev http://Trigger.dev is a developer platform for building and running AI agents and workflows. We provide everything needed to create production-grade agents: an SDK, deploying, scaling, monitoring, and debugging them without needing to manage any infrastructure. Our Cloud product is a managed service where we deploy our users' code and auto-scale from zero to millions of executions. Today, we serve thousands of teams building AI apps and agents, handling hundreds of millions of executions per month. ABOUT THE POSITION We're hiring a Senior Site Reliability Engineer to keep Trigger.dev http://Trigger.dev fast, observable and hard to break as we scale. You'll work across our open source codebase and the Cloud product that runs it in production. We're handling hundreds of millions of executions a month on infrastructure we run ourselves, and the next order of magnitude needs someone who thinks in distributed systems and treats observability and security as part of the product, not bolted on later. Day to day you'll be chasing bottlenecks, hardening services like the sandbox runtime that executes untrusted user code, and making the platform legible to the engineers running it at 3am. WHAT YOU'LL BE DOING You'll do a variety of things including: - Owning observability across the platform. Extending our OpenTelemetry instrumentation, sanding down noisy signals, and making metrics, logs and traces something engineers actually reach for during incidents. - Designing and operating the distributed systems primitives we lean on (queues, schedulers, checkpoints, idempotency, backpressure) under real production load. - Architecting and tuning the auto-scaling infrastructure that runs untrusted customer code at high throughput. - Hunting bottlenecks across the stack, from Postgres query plans and Redis hot keys down to kernel, cgroup and network behaviour. - Hardening the security posture of our multi-tenant runtime: sandbox isolation, secrets handlin
