About The Position

Mirantis is seeking a Senior DevOps Engineer to join the MOSK (Mirantis OpenStack for Kubernetes) product team. The role works at the intersection of OpenStack, Kubernetes, and product engineering to design, validate, and evolve a cloud-native OpenStack platform for enterprise private clouds. The engineer will serve as a technical authority on OpenStack and MOSK behavior, contribute to architectural decisions, support complex customer scenarios, and help deliver stable, high-quality product releases.

The position includes shaping the product roadmap, evaluating customer feature requests against upstream OpenStack code and specifications, and designing lifecycle management for OpenStack on Kubernetes, including upgrades, patching, scaling, rollbacks, and compatibility. It also involves validating features, reviewing technical designs and implementations, leading engineering discussions, and developing frameworks, tools, automation, and CI/CD workflows.

The engineer will provide Tier-3 support for complex customer production issues, investigate and troubleshoot OpenStack services, analyze performance and scalability, maintain development and validation environments, and provide accurate technical guidance to documentation, field, and enablement teams. Mirantis describes its culture as global, collaborative, and remote-first, focused on open-source innovation and enterprise cloud and AI infrastructure.
