Senior DevOps Engineer, OpenStack Team

We are looking for a Senior DevOps Engineer to join the MOSK (Mirantis OpenStack for Kubernetes) product team, working at the intersection of OpenStack, Kubernetes, and product engineering. In this role, you will help design, validate, and evolve a cloud-native OpenStack platform that enables customers to build and operate enterprise-grade private clouds at scale.

As a senior engineer, you will act as a technical authority on OpenStack and MOSK behavior, contribute to architectural decisions, support complex customer scenarios, and help ensure stable, high-quality product releases.

Key Responsibilities

Feature Design & Development

• Contribute to Product Roadmap: Actively influence the MOSK roadmap and backlog by providing technical input on feature feasibility, architectural scalability, and long-term maintainability. Evaluate incoming customer requests for specific features by analyzing upstream OpenStack code, specifications, blueprints, and community documentation to assess feature maturity, stability, limitations, and operational caveats.

• Lifecycle Management Engineering: Design, implement, and document lifecycle management for OpenStack on Kubernetes — a core MOSK capability — with emphasis on non-disruptive upgrades, patching, scaling, rollback strategies, and feature compatibility across upgrades.

• Feature Validation & Integration: Drive validation of enabled features by defining test scenarios, validating upstream code behavior in simulated or production-like deployments, and then integrating feature support into MOSK’s lifecycle management.

• Technical Design Reviews: Review and refine product designs, APIs, and implementations to ensure robustness, security, and a high-quality developer experience.

• Engineering Leadership: Lead design discussions, planning sessions, and retrospectives; help the team to uphold high standards for software quality, architectural rigor, and operational readiness.

Product Engineering & Automation

• Frameworks & Tooling Development: Design, implement, and maintain core frameworks, libraries, and internal tools that underpin MOSK development, testing, and lifecycle operations.

• Advanced Automation: Build and evolve automation for deploying and managing complex OpenStack-on-Kubernetes environments used in development, testing, and validation.

• CI/CD Architecture: Design, build, and maintain CI/CD pipelines and integrations with external systems to streamline build, test, validation, upgrade, and release workflows.

Operational Reliability

• Tier-3 Escalation Support: Debug and resolve complex issues in customer production environments involving Kubernetes, OpenStack, networking, storage, and distributed systems.

• Upstream Troubleshooting & Contributions: Investigate issues in OpenStack services, analyze root causes at the code level, and propose or contribute minor fixes upstream to improve product stability and supportability.

• Performance & Scalability Analysis: Identify and analyze performance bottlenecks across hardware and software layers; provide fixes, optimizations, and tuning recommendations.

• Operational Readiness: Manage and improve development, staging, and validation environments that closely mirror customer deployments to ensure release stability.

• Product Knowledge Authority: Act as an authoritative technical source for MOSK and OpenStack behavior, providing accurate, engineering-level input to documentation, field, and enablement teams to ensure correctness and consistency of product documentation and guidance. Participate in technical reviews, demos, and knowledge-sharing sessions to support engineering and other customer-facing teams.
