Relativity Space Jobs Information

What are the key skills and qualifications needed to thrive as a Senior Test Engineer, and why are they important?

To thrive as a Senior Test Engineer, you need advanced knowledge of software testing methodologies, test automation, and quality assurance principles, typically supported by a degree in computer science or a related field. Expertise with automation tools such as Selenium, JUnit, or TestNG, and familiarity with CI/CD systems like Jenkins are often required, as well as certifications like ISTQB. Strong analytical thinking, problem-solving abilities, and effective communication skills distinguish top performers in this role. These skills are crucial for ensuring software reliability, optimizing testing processes, and collaborating effectively with development teams.

How does a Senior Test Engineer typically collaborate with development and product teams during the software release cycle?

As a Senior Test Engineer, you will work closely with software developers and product managers throughout the software release cycle. You'll participate in design and requirement reviews to identify potential quality issues early, help define testing strategies, and provide feedback on testability. Regular communication and collaboration are essential, as you'll often coordinate test plans, report on defects, and ensure that issues are resolved before release. This cross-functional teamwork not only helps deliver high-quality software but also broadens your understanding of the product and enhances your problem-solving skills.

What are Senior Test Engineers?

Senior Test Engineers are experienced professionals responsible for designing, implementing, and overseeing testing processes to ensure the quality and reliability of software products or systems. They develop test plans, create automated and manual test cases, and collaborate with developers and other stakeholders to identify and resolve issues. Their role often includes mentoring junior team members, improving testing strategies, and ensuring that products meet industry standards and customer requirements.

What is the difference between Senior Test Engineer vs QA Analyst?

AspectSenior Test EngineerQA Analyst
CredentialsBachelor's in Computer Science or related field; experience in testing; certifications like ISTQBBachelor's in IT, Computer Science, or related; testing experience; ISTQB certification often preferred
Work EnvironmentSoftware development teams; involved in test planning, automation, and executionQuality assurance teams; focuses on manual testing, documentation, and process improvement
Industry UsageUsed across software, tech, and IT industries for testing rolesCommon in software development, IT, and tech sectors for quality assurance

While both roles focus on software quality, Senior Test Engineers typically handle more complex testing tasks, automation, and test strategy, whereas QA Analysts often focus on manual testing, documentation, and process adherence. The Senior Test Engineer role usually requires more technical expertise and experience in automation tools.

Job description

At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll 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 we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Stennis Test team designs, builds, and operates Relativity's propulsion and stage test stands. Team members are hands-on with large-scale, complex systems including fully integrated engines and stage assemblies, pushing hardware to the limits and directly contributing to flight readiness. The work is fast-paced and highly operational, ideal for those with backgrounds in aviation, automotive, manufacturing, offshore operations, industrial systems, construction, or adjacent industries. You'll work in a close-knit, dynamic environment where collaboration between technicians, operators, and engineers is not only encouraged, but expected. As the company scales, the Stennis Test team becomes even more critical to unlocking our next phase of growth: proving out full-stage systems and paving the way for routine, reliable flights of Terran R.

About the Role:

As a Senior Propulsion Test Engineer at Relativity, you will be responsible for design, fabrication, and modification of test stands for our Terran 1 and Terran R engines and stages. Engineers at our Stennis facility are engaged directly with construction and maintenance activities in the field, across a variety of hours to years-long project scales. This position will be titled Senior Propulsion Test Engineer within the organization.

  • Design advanced propulsion test stands, including 3D modeling, fluids and structural analysis, fabrication drawings, fluids P&IDs, component lists, and detailed work instructions
  • Supervise the construction, commissioning, and initial operations of these facilities
  • Solve a variety of technical problems, across broad ranges of timeframe, complexity, cost, and long-term impact
  • Support operations on and perform related improvements to existing test stands
  • Ability to work occasional night shifts

About You:

  • Bachelor's degree in mechanical engineering, aerospace engineering, or a related field and 5+ years of combined engineering experience is required
    • Prior experience in aerospace is not required
    • Varied perspectives & backgrounds strengthen our team
  • Ownership of propulsion or structural test related projects including design, analysis, construction, and commissioning from beginning to end as well as proficiency in 3D modeling and drafting, including GD&T
  • Demonstrated engineering fundamentals in thermal, structural, and fluids analysis as well as a demonstrated drive to deliver on tight schedules, especially when unconventional & creative solutions are necessary
  • Hands-on fabrication experience using common power tools for projects at work/home/school
  • Knowledge of fluid components such as valves, regulators, and instrumentation as well as experience designing, fabricating, and operating complex fluid systems
  • This position requires a valid driver's license in order to operate vehicles on the test site

Nice to have but not required:

  • Experience with FEA or CFD
  • Hands-on experience with metalworking, welding, hydraulics, manufacturing, etc.
  • In depth knowledge of manufacturing processes, material selection, inspection, precision measurement, and non-destructive testing

Successful candidates must clear a background check administered by the US government to obtain clearance for on-site work at our government partner location in Stennis, Mississippi.
