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.
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
Must-haves
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
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)
What we look for beyond the CV
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
