Company Description

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. By combining open source innovation with deep expertise in Kubernetes orchestration, Mirantis empowers platform engineering teams to deliver composable, production-ready developer platforms across any environment—on-premises, in the cloud, at the edge, or in sovereign data centers. As enterprises navigate the growing complexity of AI-driven workloads, Mirantis delivers the automation, GPU orchestration, and policy-driven control needed to manage infrastructure with confidence and agility. Committed to open standards and freedom from lock-in, Mirantis ensures that customers retain full control of their infrastructure strategy. https://www.mirantis.com/

Job Description

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. You will make our development, test, and pre-production clusters fast and reproducible, harden the Helm and CI/CD path from commit to release, and carry operational ownership — including on-call — for one of our smaller customer-facing production regions, under real availability commitments. That production experience makes you the internal expert on how k0rdent AI is deployed and operated — the person other teams consult, including the teams running our larger regions. Working within an agile framework, you will directly shape how quickly and safely changes reach production, and be accountable for how they behave once there.

Main 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.
Build and maintain Helm charts and umbrella releases for the platform's services and dependencies, including versioning, values hygiene, and upgrade paths.
Own the CI/CD pipelines end to end — build, test, image publishing, chart packaging, release cutting, and hotfix/backport flows.
Automate environment bootstrap and seeding so any engineer can bring up a full stack — control plane, identity, gateway, database, workflow engine — with one command.
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, log and audit access — that serve both engineering environments and production operations.
Consult with product teams and with the teams operating our larger regions on deployment topology, GPU and resource scheduling, RBAC, networking, and failure modes; validate upgrade and migration procedures and hand over runbooks.
Enforce security and tenant isolation in production: least-privilege access, secret handling, certificate and TLS lifecycle, image and dependency scanning, and audit evidence for compliance reviews.
Drive infrastructure as code and repeatability — no snowflake environments, no undocumented manual steps.
Mentor engineers on Kubernetes and operational practice, and raise the team's bar through review and documentation.

Qualifications

Required Skills/Abilities:

10+ years in DevOps, SRE, platform, or infrastructure engineering, including production ownership of customer-facing Kubernetes environments.
Expert-level Kubernetes: workloads, networking, storage, RBAC, resource management, CRDs and operators, and cluster upgrades — able to debug from kubectl and cluster internals rather than dashboards alone.
Proven incident response under SLA pressure — on-call rotations, escalation paths, postmortems, and follow-through on corrective action.
Strong CI/CD engineering — pipelines as code, reproducible builds, artifact and release management (GitHub Actions or equivalent).
Solid scripting and automation ability, and enough Go familiarity to read service code, trace a failure into it, and file a precise bug.
Experience running the stateful supporting stack — relational databases, identity providers, gateways, and message brokers — in Kubernetes, including backup, restore, and upgrade.
Track record as a technical consultant to other engineering teams: clear runbooks, design feedback, and incident write-ups across global time zones (strong written English).

Must Have

We expect deep production experience in several of these, and the engineering fundamentals to learn the rest rapidly.

Kubernetes Native: Kubernetes at scale, Cluster API, controllers/operators, Docker, and Helm chart authoring and lifecycle management.
Delivery: GitHub Actions or equivalent CI/CD, container registries, versioned release and backport workflows.
Infrastructure as Code: Terraform, Ansible, or equivalent, plus GitOps tooling (Argo CD, Flux).
Identity & API Management: Keycloak and API gateway operation — routing, plugins, TLS, rate limiting.
Data & Messaging: PostgreSQL operations and migrations, plus streaming/message-broker platforms (Kafka or equivalent).
Observability: Prometheus, Grafana, centralized logging, and alerting tied to SLOs.
Cloud: AWS— networking, IAM, load balancing, and managed Kubernetes

Nice to Have

k0s or k0rdent ecosystem experience.
GPU infrastructure on Kubernetes — device plugins, node feature discovery, scheduling and sharing of accelerators.
Temporal operations — namespaces, workers, schema upgrades.
Bare-metal provisioning (Metal³ / BareMetalHost) or on-prem/OpenStack environments.
Multi-region topologies, service mesh, or cross-cluster networking.
Python for test harnesses and automation; experience with pytest-based E2E suites.
Load and performance testing of API platforms.
Policy enforcement (OPA/Kyverno), secret management, and pen-test remediation.
OpenTelemetry, distributed tracing, or formal SLO/error-budget practice.
Compliance exposure — SOC 2, ISO 27001, or similar audit support.
CNCF open-source contributions.

Education and Experience:

Bachelor’s degree in Computer Science & Engineering or related field or 10 years related experience.
