Senior Site Reliability Engineer
Senior Site Reliability Engineer
> ROLE OVERVIEW
Mirantis, an IREN company, is the Kubernetes-native AI infrastructure company, enabling organizations to build and operate scalable, secure, and sovereign infrastructure for modern AI, machine learning, and data-intensive applications. We are looking for a senior Kubernetes-focused DevOps/SRE engineer to own both the developer platform and a customer-facing production region of a multi-tenant control plane for enterprise GPU infrastructure. You will build and run the environments, pipelines, and infrastructure tooling that our engineering teams across the US, Europe, and APAC depend on to ship daily. This role spans both sides of the line, making our development, test, and pre-production clusters fast and reproducible, hardening the Helm and CI/CD path from commit to release, and carrying operational ownership — including on-call — for one of our smaller customer-facing production regions, under real availability commitments.
> CORE RESPONSIBILITIES
- Own the Kubernetes footprint across development, CI, pre-production, and one customer-facing production region — local kind clusters, shared dev and QA environments, and multi-cluster/multi-region topologies.
- Operate your production region against defined SLOs: capacity and upgrade planning, patching, backup and restore, disaster recovery drills, and participation in an on-call rotation.
- Lead incident response for your region — detection, mitigation, customer-impact assessment, root-cause analysis, and blameless postmortems that feed fixes back into the platform.
> HARD REQUIREMENTS & SPECS
- Operate and troubleshoot the supporting stack across test and production: PostgreSQL, Temporal, Keycloak, API gateway, message broker, and observability components.
- Build observability and diagnostics — metrics, dashboards, alerting, and logging.
- Automate environment bootstrap and seeding so any engineer can bring up a full stack — control plane, identity, gateway, database, workflow engine — with one command.
