About the role

Posted Oct 16, 2026

As a Site Reliability Engineer at Material Security, you'll own the reliability of the infrastructure every product team builds on, including GCP, Kubernetes, and Postgres across hundreds of GCP projects. This is a software engineering role, where you’ll be building systems and the culture that removes manual on-call work, fixes the underlying causes of alerts, and gives engineers a clear view of system health. You'll work with every team and work with leadership to decide where things go..

Responsibilities

  • Design and build software that removes manual on-call intervention and recurring sources of toil.

  • Lead infrastructure projects end to end.

  • Find where cost-driven limits create latency or reliability problems, and fix the trade-off.

  • Build tooling that shows system health across our GCP projects at a glance.

  • Define SLOs with product teams and raise the bar on reliability practice across engineering.

  • Pioneer reliability engineering for agent-first production systems.

What We’re Looking For

  • Technical Ability: Solid software engineering fundamentals and raw coding ability. Production code is your default way of solving a problem.

  • Infrastructure Depth: Hands-on experience running GCP (or a comparable cloud) and Kubernetes at production scale, including autoscaling and capacity management.

  • Automation First: You have built tools and automation that other engineers depended on, not just runbooks that describe a manual fix.

  • Ownership: Comfortable driving ambiguous, cross-team reliability work on your own, from diagnosis to a shipped fix.
