Hardware Infrastructure & CI/CD Engineer

CI/CD Ownership

• Pipeline Design & Maintenance: Own and maintain GitHub Actions CI/CD pipelines across three development teams, ensuring consistent, reliable, and performant builds, tests, deployments, and health checks
• Shared CI/CD Platform: Develop reusable workflows, composite actions, and shared libraries to standardize CI/CD patterns across teams while accommodating team-specific needs
• Developer Experience: Act as the primary point of contact for CI/CD-related issues across teams; triage failures, unblock developers, and reduce mean-time-to-green for pull requests
• Build & Test Optimization: Continuously improve pipeline speed, caching strategies, runner utilization, and test parallelization to reduce CI/CD cycle times and infrastructure costs
• Cloud-Based CI/CD Infrastructure: Operate and optimize cloud-based CI/CD resources, including hosted and ephemeral runners, distributed build/test caching, and artifact/object storage backends
• Self-Hosted Runners: Manage self-hosted GitHub Actions runners, including those with hardware attachments, ensuring capacity, security, and reliability across teams
• Package & Artifact Management: Operate and maintain PyPI services (e.g., private package indexes, mirrors, and proxies) and other artifact repositories used by development and CI/CD workflows
• Release Engineering: Support release workflows, artifact management, versioning, and deployment automation for services and embedded firmware across teams
• Standards & Best Practices: Define and evangelize CI/CD best practices, branch protection policies, testing standards, and security/secret-management practices across the organization
• Cross-Team Coordination: Partner with leads from each development team to align CI/CD roadmaps, plan migrations, prioritize improvements, and communicate changes that affect developer workflows
• Documentation & Enablement: Produce clear technical documentation, onboarding guides, and runbooks; provide training and office hours to help teams adopt and contribute to shared CI/CD infrastructure

Required Qualifications & Experience

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field — or equivalent practical experience
• 5+ years of professional experience in a related infrastructure, DevOps, test engineering, or full-stack systems role
• Hands-on embedded hardware and software development experience, including working with embedded toolchains and bring-up of new hardware platforms
• Demonstrated experience owning CI/CD systems that serve multiple development teams or a large engineering organization
• Go: Strong proficiency, including experience building production services with HTTP APIs and WebSockets
• C/C++: Demonstrated ability to write, debug, and maintain systems-level or test code.
• Python: Solid experience using Python for tooling, automation, and scripting
• Kubernetes: Hands-on experience operating and maintaining multi-cluster environments, including queueing and load balancing patterns
• Docker: Proficient at writing Dockerfiles, building/pushing images, and managing complex toolchain containers
• Databases: Practical experience with PostgreSQL (operations workloads) and Redis (caching)
• CI/CD: Deep experience designing and maintaining GitHub Actions pipelines, including reusable workflows, composite actions, matrix builds, caching, and self-hosted runners
• Cloud-Based CI/CD: Hands-on experience with cloud-based CI/CD infrastructure, including managed/ephemeral runners, distributed caching strategies, and artifact/object storage
• Package Services: Experience operating or integrating with PyPI services (private indexes, mirrors, or proxies) and managing Python package distribution in CI/CD environments
• Cross-Team Collaboration: Proven ability to support and influence multiple engineering teams, balancing competing priorities and driving shared standards
• Communication: Excellent written, verbal, and technical communication skills, with the ability to clearly document systems, lead discussions across teams, and produce developer-facing materials

Desired Qualifications & Experience

• Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field
• Experience with JTAG/SWD debugging tools and workflows
• Familiarity with energy and power measurement tools (e.g., power monitors, current probes, instrumented test fixtures)
• Experience designing hardware-in-the-loop (HIL) test systems or large-scale automated benchmarking infrastructure
• Background in performance profiling, benchmark design, or comparative hardware analysis.
• Experience operating developer productivity / build engineering functions at scale, including metrics-driven improvements (e.g., DORA metrics, CI/CD cycle time, flaky test reduction)
• Familiarity with release engineering practices for both cloud services and embedded firmware.
• Experience with secrets management and CI/CD security best practices
• Experience administering artifact/package ecosystems
