About the role

Role focused on building and owning Blockit's production-ready infrastructure for a stateful, multiplayer AI agent. You’ll improve user-facing performance and reliability through core data systems, observability, and developer experience, shaping the platform that coordinates millions of calendars.

Responsibilities

  • Own, operate, and evolve our core data infrastructure: PostgreSQL, ClickHouse, and async processing pipelines — measuring success in user-facing terms (p95 scheduling latency, agent action success rate, message delivery reliability)
  • Own observability end-to-end: metrics, logs, traces, alerting, dashboards, and the on-call / pager rotation — including what we alert on and what we don't
  • Design, manage, and optimize our LLM infrastructure (gateway, evaluation pipelines, agent observability) for reliability, performance, and cost
  • Lead infrastructure migration decisions and execute them: e.g. evaluating pg-boss vs. managed queue alternatives, weighing whether to move off Postmark, introducing Redis / Kafka / similar when the time is right
  • Partner directly with product engineers to ship features — the line between "infra work" and "product work" should be invisible here
  • Own DevX: shape how engineers leverage AI in their day-to-day workflow — local environments, Claude Code conventions, agent tooling, eval harnesses, anything that compounds team velocity
  • Own DevOps: deploy pipelines, environment management, capacity planning, infra cost

Qualifications

  • 4+ years of software engineering experience, with significant time on backend or infrastructure
  • Product sensibility — you reach for user-facing metrics first, and you can tell the difference between an infra problem that matters and one that doesn't
  • Deep with databases — you can read query plans, find the bottleneck, and know when to fix the query vs. fix the schema vs. fix the architecture
  • Have run production services and owned the pager — comfortable in an incident, methodical in the postmortem
  • Familiar with job queues, async processing, or event-driven systems, and have opinions on when each is the right tool
  • Interest in developer tooling and how AI changes the way engineers should work
  • Pragmatic about build vs. buy — you don't reinvent infrastructure for fun, and you don't outsource what should be core
