Relativity Space Jobs Information

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

To thrive as a Test Engineer, you need a solid background in software development, quality assurance principles, and test case design, often supported by a degree in computer science or a related field. Familiarity with automated testing tools like Selenium, JUnit, or TestNG, as well as experience with bug tracking systems and scripting languages, is typically required. Attention to detail, problem-solving ability, and effective communication are crucial soft skills for identifying issues and collaborating with development teams. These skills ensure the delivery of reliable, high-quality products by efficiently detecting and resolving software defects.

How do Test Engineers typically collaborate with development and product teams during a project?

Test Engineers play a crucial role in cross-functional teams by working closely with developers and product managers throughout the software development lifecycle. They participate in requirement reviews, design discussions, and sprint planning meetings to ensure testability and clarity of features. Regular communication helps identify potential issues early, align on acceptance criteria, and prioritize testing efforts. This collaborative approach helps deliver higher-quality products and fosters a culture of continuous improvement.

What are Test Engineers?

Test Engineers are professionals responsible for evaluating and ensuring the quality of products, typically software or hardware, by designing and executing tests. They identify bugs, glitches, or any issues that might affect the user experience or product performance. Test Engineers also document test results, collaborate with developers to resolve issues, and help improve processes to prevent future problems. Their work is critical in delivering reliable and high-quality products to customers.

What is the difference between Test Engineer vs QA Analyst?

AspectTest EngineerQA Analyst
Required CredentialsBachelor's in Engineering, Computer Science, or related field; certifications like ISTQBBachelor's in related fields; ISTQB certification common
Work EnvironmentSoftware development teams, testing labs, automation toolsQuality assurance teams, process documentation, testing environments
Employer & Industry UsageTech companies, software firms, manufacturingIT services, software development, healthcare

Test Engineers focus on designing, executing, and automating tests to ensure software quality, often working closely with developers. QA Analysts primarily analyze quality processes, develop testing plans, and ensure compliance with standards. While both roles aim to improve product quality, Test Engineers are more technical and automation-oriented, whereas QA Analysts emphasize process and manual testing. Understanding these differences helps in choosing the right career path or job role.

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:
