Senior DevOps Engineer - Platform

As a Senior DevOps Engineer on our Platform Engineering team, you own critical components of our CI/CD systems, embedded Linux workflows, release infrastructure, and developer platform serving robotics and defense-grade software engineers. You are a hands-on technical expert: you design and implement solutions end-to-end, mentor engineers on your team and across the organization, and maintain the deep technical knowledge required to make sound architectural decisions. You own specific infrastructure subsystems as a product-the internal customers are our robotics, embedded, and systems engineers-and you are accountable for their reliability, security, and evolution. This is a technical individual-contributor role. You are expected to work comfortably in our application and platform code, understand native build systems, and be literate in the middleware and runtime components (e.g., ROS 2/DDS) that run on top of the platform, so the systems you design reflect what we actually compile, test, and ship.

The day-to-day

• Design, implement, and maintain CI/CD pipelines, release infrastructure, and developer tooling end-to-end; own the quality and reliability of systems you build
• Develop and evolve embedded Linux build workflows, including Yocto-based image pipelines and related tooling; drive improvements in reproducibility and build performance
• Collaborate closely with robotics, embedded, and systems engineers on build systems, testing infrastructure, and release workflows for drone and defense-grade software
• Drive reliability, observability, reproducibility, and security across build and deployment systems; identify and resolve infrastructure bottlenecks
• Define and enforce best practices for automated testing, artifact management, branching strategies, and deployment workflows
• Step into complex issues across infrastructure, build systems, pipelines, and codebases; unblock the team and mentor colleagues to resolve similar issues independently
• Contribute to and shape the broader engineering platform strategy spanning CI/CD, developer infrastructure, operating systems, and engineering security practices
• Mentor junior engineers and external stakeholders on DevOps best practices, build systems, and platform architecture

• Proven track record as a DevOps, build-and-release, or platform engineer-typically 5+ years-after a degree in computer science or comparable qualification
• Proficiency in at least one systems programming language (e.g., C/C++ or Rust) and the ability to read and reason about native-code application codebases with confidence
• Deep, practical understanding of modern GNU/Linux systems (preferably Ubuntu/Debian-based) and how native applications are built, packaged, tested, and shipped
• Professional experience implementing and maintaining CI/CD tooling such as GitLab CI or GitHub Actions; you can design and build pipelines from scratch
• Strong experience with native-code build systems and tooling (e.g., CMake and/or Bazel; build caching such as sccache or equivalent)
• Working understanding of robotics middleware/runtime concepts (e.g., ROS 2, DDS, serialization formats) sufficient to reason about what runs on top of the CI/CD and release platform
• Familiarity with Yocto concepts (layers, recipes, image assembly) as they relate to CI/CD pipelines and release engineering
• Python and Shell as daily drivers: you write production-grade automation, not quick scripts
• Proven ability to analyze complex infrastructure and code issues independently and communicate findings clearly
• Demonstrated ability to mentor engineers and raise the technical bar in teams you join

Nice to haves

• Professional expertise with Infrastructure-as-Code tools (Terraform, Pulumi, Ansible)
• Hands-on experience with Docker and Kubernetes in production environments
• Experience in embedded or hardware-adjacent software environments (firmware pipelines, cross-compilation toolchains)
• Deeper Yocto experience (custom layers/recipes, build-graph troubleshooting) or familiarity with embedded Linux update frameworks (e.g., Mender)
• Familiarity with modern engineering security practices such as SBOMs, artifact signing, vulnerability scanning, secrets management, or supply-chain security
• Experience with observability and monitoring tooling such as Prometheus, Grafana, ELK/OpenSearch, or similar
• Familiarity with identity/access systems, VPNs, device management, or internal engineering infrastructure
• Familiarity with security frameworks relevant to defense or regulated software environments (ISO 27001, BSI Grundschutz), * You raise the bar: you care deeply about quality, ownership, and sustainable engineering practices
• You think in systems: pipelines, infrastructure, operating systems, security, and engineering workflows are interconnected systems to be designed and continuously improved
• You are comfortable with ambiguity and energized by solving infrastructure problems that don’t have obvious solutions
• You balance strategic thinking with hands-on execution-equally credible in a code review and in an architecture discussion
• You are generous with knowledge: you mentor teammates, document decisions clearly, and help the broader organization benefit from what you build
