Senior Software Release Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll collaborate across teams shape decisions and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand and your voice will help define the stories were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

Relativity Space is on a mission to better connect humanity to space and the universe beyond our decades of experience scaling world-class technology organizations like Google CEO Eric Schmidt is guiding Relativity into itsnext phase: advancing Terran R toward launch and building the foundation for long-term impact.

The Vehicle Software team develops the safety-critical software that runs on Terran R. The work spans a distributed real-time control system operating under extreme conditions like Mach 5 atmospheric flight with a deployment pace that allows you to see your code run on rocket engines daily. The team is building new system architecture from the ground up and just as importantly testing releasing and deploying it. You dont need an aerospace background: what matters is experience with high-reliability software for complex systems. This is a rare opportunity to shape the foundation of Terran Rs software stack while directly influencing performance reliability and flight success.

About the Role:

As a Senior Release Engineer on the TRADE team youll own the release lifecycle of integrated vehicle software. Youll lead the coordination packaging validation and deployment of software across diverse environments ensuring that each release is stable tested and ready for use by partner teams across production integration and launch.

This role is deeply cross-functional and highly execution-focused. Youll need strong technical judgment attention to detail and a proactive mindset to manage software releases under evolving requirements and aggressive timelines.

You will:

• Own the end-to-end vehicle software release process including packaging versioning traceability and readiness reviews.
• Develop automation and scripting (primarily in Python) to streamline release workflows validation steps and artifact management.
• Build and maintain tools to validate and publish integrated release candidates from multiple software teams (FSW ESW Proxy tools etc).
• Coordinate closely with software developers systems engineers test operators and integration teams to align releases with testing and operational needs.
• Lead and execute Run-for-Record campaignsensuring environments are prepared results are captured and test artifacts are properly reviewed and stored.
• Support post-release deployment to production and test environments; validate successful integration and assist with troubleshooting where needed.
• Improve CI/CD integration and pre-release testing to catch issues earlier and ensure continuous delivery readiness.
• Organize and facilitate data reviews provide release documentation and support software audits and anomaly investigations.

About You:

• 4 years of professional experience with 2 years in software release engineering systems integration test engineering or a related field.
• Strong Python scripting experience focused on automation tooling or test infrastructure.
• Demonstrated ownership of complex software release processes involving multiple teams or components.
• Familiarity with CI/CD workflows artifact packaging versioning strategies and testing pipelines.
• Experience coordinating across disciplines (e.g. software hardware operations) to align on software delivery goals.

Nice to haves but not required:

• Experience with software release processes for aerospace systems launch vehicles or other high-reliability domains.
• Familiarity with Conda GitLab CI/CD version control practices and artifact repositories.
• Experience working with hardware-in-the-loop (HITL) simulation environments or large-scale system integration.
• Strong analytical skills and experience supporting data reviews root cause investigations or release audits.
