Senior Software Release Engineer

Long Beach, California

At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team: 

TRADE (Test, Release, and Deployment Engineering) is a core engineering team within Vehicle Software at Relativity Space. As we scale from development to full-scale vehicle integration and launch operations, TRADE ensures our software is rigorously tested, confidently released, and successfully deployed across all environments—from simulation to the launch pad.

TRADE is internally focused, enabling software teams to move fast while maintaining high standards of reliability, traceability, and performance. We own the workflows, tools, and processes that make integrated software delivery possible at the vehicle level.

About the Role:

As a Senior Release Engineer on the TRADE team, you’ll own the release lifecycle of integrated vehicle software. You’ll 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. You’ll 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 campaigns—ensuring 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.

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
