Voyager Technologies is an innovative space, defense, and national security technology company building transformative, mission-critical solutions for spacecraft, lunar systems, and national security applications.
As Senior Software Build & Release Engineer for Voyager Lunar Systems, you will own the end-to-end automation of software builds, versioning, deployment, and delivery for the lunar lander program. You report to the Software & Controls Manager and are based in Pittsburgh, PA (onsite).
Key responsibilities:
• Own release engineering end-to-end for flight and ground software, from pipeline architecture through final software package generation.
• Design and evolve branching and release strategy, including GitFlow-based models with release branches, automated semantic versioning, and promotion gates that define alpha builds, release candidates, and releases.
• Build and maintain GitLab CI/CD pipelines that compile, test, version, publish, and deploy software. Triage and resolve infrastructure-related failures and regressions.
• Integrate automated and manual test campaigns into the release process, ensuring every build has a clear, auditable test record.
• Deploy and operate on-premises infrastructure for critical engineering services, including GitLab and GitLab Runners, Slurm HPC clusters, Jira, Confluence, Harbor, and MinIO.
• Own Linux-based spacecraft flat-sat platforms. Work with test engineers to build Python tooling and custom Docker containers for automated deployment and testing.
• Set engineering standards for build, test, and release practices across software teams.
This is a hands-on technical role requiring deep expertise in DevOps, build systems, and release engineering for mission-critical systems. You will be the primary owner of infrastructure, responsible for both architecture and implementation.
REQUIREMENTS:
Minimum Qualifications:
• 5+ years of DevOps, build, or release engineering experience supporting robotics, spacecraft, embedded, or other mission-critical systems.
• Hands-on ownership of GitLab CI/CD, including pipelines, runners, package registry, and releases.
• Strong Python skills for pipeline automation, release tooling, scripting, and pytest-based test frameworks.
• Experience with Bazel, particularly for multi-language (C++/Python) builds, remote caching, or migrating existing projects from Make/CMake.
• Experience with Docker and with Make/CMake build systems.
• Track record of designing or significantly shaping branching and release strategies, such as GitFlow, release branches, semantic versioning, and promotion gates.
• Solid Linux administration experience, including deploying and maintaining self-hosted engineering services.
• Comfort as the primary or sole owner of infrastructure, responsible for both architecture and hands-on implementation.
• Must be a U.S. person as defined by ITAR.
Preferred Qualifications:
• Working proficiency in C++, particularly around build, test, and packaging.
• Experience running simulation or compute workloads on HPC clusters (Slurm).
• Experience with container registries and object storage (Harbor, MinIO).
• Prior work in ITAR/CUI-controlled environments.
• Informal technical leadership experience, such as mentoring engineers or driving cross-team adoption of tooling and process.
