About the role

Shipping infrastructure software is only half the job.
The difference between a good product and a trusted one is how quickly you can diagnose issues and how effectively you prevent them from happening again.
WHY THIS ROLE EXISTS We need someone who can operate in both worlds: diving deep on gnarly customer escalations while systematically eliminating entire classes of problems.

Drive issues to resolution by reproducing problems locally, isolating root causes, and coordinating fixes with engineering-then documenting learnings in crisp RCAs that become actionable improvements
Establish and maintain performance baselines and regression tests that serve as actionable gates, helping teams catch scale and latency issues early
When something breaks in the field, it's not just a support ticket-it's a signal about what we need to fix, test, or instrument better.
Own the test automation infrastructure roadmap, improving CI stability, reducing flaky tests, and creating reproducible integration/e2e environments that catch issues before customers do
Strong software engineering fundamentals including design, debugging, testing, code review, and a focus on maintainable, production-quality code

4-7 years of experience in production engineering, SRE, platform engineering, or similar roles where you've owned reliability and customer escalations
Practical Kubernetes expertise sufficient to debug real deployments: troubleshooting resources, networking, storage, RBAC, and platform-specific quirks across different distributions
Deep troubleshooting instincts and observability experience using logs, metrics, and traces to diagnose issues quickly in complex, distributed systems
Experience with at least one of: Python, Go, or Rust for building tooling and contributing to product code (you don't need to be expert in all three)
Excellent problem decomposition and communication skills-you can break down messy, ambiguous issues and clearly explain your findings and recommendations
Experience with packaging and distribution systems (containers, Helm charts, installers) and managing upgrade/migration flows
Familiarity with performance tooling such as profiling, load generation, and benchmark harnesses

Build and maintain diagnostics tooling including support bundles, health checks, environment validators, and "what changed?" helpers that make future troubleshooting 10x faster

Partner directly with customers and with our Solution Architecture/Customer Success teams on L2/L3 escalations-communicating findings, driving root-cause analysis, and resolving complex packaging, deployment, upgrade, and runtime issues across heterogeneous Kubernetes environments.
At OpsMill, we're building Infrahub, a schema-driven infrastructure source of truth that helps teams unify data and scale automation reliably.
Our customers deploy Infrahub on-prem, which means reliability is a product feature, not just an operational concern.
