Overview

Company Description

Responsibilities

• About Mirantis
• 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.
• Multi-Environment Kubernetes Operations: Deploy, upgrade, and operate k0s / k0rdent-managed Kubernetes clusters on AWS and on bare-metal hardware, across a global control plane and multiple regions — cluster lifecycle, node maintenance, capacity planning, and version upgrades.
• Helm & Service Delivery: Author and maintain Helm charts and k0rdent ServiceTemplates and MultiClusterServices for core services (Keycloak, Kong, Temporal, CloudNativePG, and in-house Go APIs), including dependency ordering, health gating, versioning, and zero-downtime upgrade paths.
• Storage & Snapshot Engineering: Design and run Kubernetes storage for each environment — AWS EBS CSI in the cloud; OpenEBS LocalPV, Longhorn, or Ceph on bare metal — including StorageClasses, reclaim policies, the CSI snapshot controller, and VolumeSnapshotClasses, so stateful services can be snapshotted and restored reliably.
• Database Backup & Recovery: Operate CloudNativePG backup and recovery end to end — scheduled volume snapshots, continuous WAL archiving to object storage, point-in-time recovery, and replica clusters — with defined RPO/RTO targets and regular restore drills.
• CI/CD & End-to-End Testing: Build and maintain GitHub Actions pipelines for linting, chart unit tests, artifact packaging and publishing to OCI registries, and on-demand bare-metal end-to-end environments; keep them fast, reliable, and easy to debug.
• GitOps & Infrastructure as Code: Maintain a strictly declarative infrastructure-as-code (IaC) culture using Terraform and Argo CD (or Flux), keeping every environment — from developer labs to production — reproducible and reviewable through code.
• Observability & Incident Response: Build monitoring and alerting (Prometheus, Grafana, OpenTelemetry) for service health, database replication and backup status, and capacity; join the on-call rotation, lead troubleshooting, and drive post-incident improvements.
• Security & Air-Gapped Delivery: Manage TLS and certificate lifecycle (cert-manager), secrets, network policies, and least-privilege RBAC, and support private-registry and air-gapped installations for sovereign customers.

Qualifications

• Platform Experience: 8+ years in DevOps, SRE, or platform engineering, including 3+ years operating production Kubernetes for business-critical services.
• Kubernetes Depth: Strong grasp of Kubernetes primitives — workloads and StatefulSets, operators and CRDs, persistent volumes and CSI storage, RBAC, and network policies — with hands-on experience upgrading and troubleshooting clusters in production.
• Helm & Release Engineering: Hands-on authoring of non-trivial Helm charts — templating, values design, chart dependencies, and testing with helm-unittest or chart-testing. Experience with k0rdent, Cluster API, or a multi-cluster delivery tool (Argo CD ApplicationSets, Fleet, Sveltos) is preferred, but what matters is depth with Helm, not the specific delivery tool.
• Kubernetes Storage: Practical experience with CSI drivers, StorageClasses, and volume snapshots — AWS EBS CSI preferred, but equivalent experience with Longhorn, Ceph (Rook), OpenEBS, or another cloud CSI driver is acceptable. What matters is understanding how storage behaves when pods, nodes, and clusters fail.
• PostgreSQL on Kubernetes: Hands-on experience running PostgreSQL through a Kubernetes operator — CloudNativePG (CNPG) preferred, but Zalando’s postgres-operator, Crunchy PGO, or a comparable operator is acceptable — including backups, restores, and point-in-time recovery.
• Cloud Infrastructure: Production experience in AWS (EC2, EBS, VPC, IAM, S3; EKS a plus); equivalent GCP or Azure experience also counts.
• CI/CD & Automation: Designing and maintaining GitHub Actions (or GitLab CI) pipelines, with solid scripting in Bash plus Python or Go (Golang).
• Collaboration: Clear written and spoken English and comfort working across time zones, with regular overlap with US and European teams.

Nice to have

• Experience with bare-metal provisioning (Metal3, Ironic, PXE) and GPU or AI infrastructure.
• Familiarity with Kong Gateway or the Kubernetes Gateway API, and Keycloak / OIDC identity integration.
• Experience operating Temporal or other workflow engines in production.
• Experience delivering software into air-gapped or sovereign environments using private registries and mirrored artifacts.
• Experience designing cross-region disaster recovery for stateful services, including RPO/RTO trade-off decisions.
• Certifications such as CKA / CKS or AWS Certified DevOps Engineer – Professional — a plus.
• Contributions to open-source infrastructure projects (Helm charts, Kubernetes operators, CNCF projects) — a huge plus.

Education

• Operate some of the most advanced AI infrastructure environments in production today.
• Work with the latest NVIDIA GPU technologies, Kubernetes platforms, and high-performance networking environments.
• Help define operational standards and reliability practices for next-generation AI infrastructure services.
• Influence the adoption of AI-powered operational capabilities through k0rdent AI.
• Work alongside highly skilled engineers solving complex infrastructure and platform challenges at scale.
• Join a growing organisation investing heavily in AI infrastructure, platform services, and operational innovation.
• Bachelor’s degree in Computer Science & Engineering (or a related field), or 8+ years of equivalent related experience.
