Senior Production Engineer

The SRE team owns reliability and infrastructure for Anduril's cloud deployments. We operate Kubernetes clusters, Terraform infrastructure, and observability platforms across 10+ production environments supporting active defense contracts. When platform services break under real operational load, we're the team that fixes them - often at the code level, not just the config level.

We are looking for a Senior Production Engineer to join our team in Costa Mesa, CA (or DC) . In this role, you will be responsible for diagnosing and fixing stability vulnerabilities in core platform services that cause cascading failures in multi-tenant cloud deployments. You will write production Go to implement resilience patterns - leader election, circuit breakers, failure domain isolation - directly in service code.

This will require deep experience with distributed systems, debugging complex failure modes across service boundaries, and writing production-quality Go. If you are someone who thrives on fixing hard reliability problems in live systems rather than building greenfield, this role is for you.

- Diagnose and fix stability vulnerabilities in core platform services that cause cascading failures under multi-replica, multi-tenant operation

- Implement resilience patterns (leader election, circuit breakers, failure domain isolation) directly in service code

- Design multi-replica support for services that currently assume single-instance operation

- Collaborate with service owners on contract testing and upgrade validation

- Trace cascading failures across service boundaries and drive them to root-cause fixes

- Contribute to observability platform improvements to support service stability

- Light infrastructure work: Terraform/Kubernetes changes to support service fixes (~20% of time)

- Production-quality Go - you'll be modifying core platform services, not writing scripts

- Practical experience with distributed systems: leader election, consensus, replication, failure modes

- Kubernetes - enough to understand how services run (not necessarily cluster administration)

- Debugging complex systems - tracing cascading failures across service boundaries

- 4+ years in SRE, platform engineering, or backend development roles

- Must be a U.S. Person due to required access to U.S. export controlled information or facilities

- Eligible to obtain and maintain an active U.S. Secret security clearance

- Experience fixing reliability problems in production services (not just building greenfield)
