What does an entry level simulation software engineer do?

An Entry Level Simulation Software Engineer develops and tests software that models real-world systems, such as physical processes, engineering designs, or virtual environments. They typically work under the guidance of senior engineers to write code, run simulations, analyze results, and troubleshoot issues. Their work helps organizations predict system behavior, optimize designs, and reduce the need for costly physical prototypes. This role often involves programming, understanding mathematical models, and collaborating with other engineering teams.

What are the key skills and qualifications needed to thrive as an entry level simulation software engineer?

To thrive as an Entry Level Simulation Software Engineer, you need a solid background in computer science, mathematics, and programming languages such as C++, Python, or Java, typically supported by a relevant degree. Familiarity with simulation frameworks, modeling tools (like MATLAB or Simulink), and version control systems (such as Git) is often required. Strong problem-solving skills, attention to detail, and effective teamwork are essential soft skills for this role. These abilities enable engineers to develop accurate, efficient simulations and collaborate effectively in multidisciplinary teams, ensuring successful project outcomes.

What are some common challenges faced by entry level simulation software engineers, and how can they be overcome?

Entry level simulation software engineers often encounter challenges such as understanding complex simulation models, learning industry-specific tools, and collaborating with multidisciplinary teams. To overcome these hurdles, it's helpful to actively seek mentorship from senior engineers, participate in team meetings to gain context, and dedicate time to hands-on practice with simulation tools. Regular communication with team members and taking advantage of available documentation can also accelerate learning and integration into the workflow.

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 Guidance, Navigation, and Control (GNC) and Performance teams are responsible for defining and analyzing how Terran R flies, from liftoff to landing. The work combines a variety of disciplines such as advanced modeling, orbital mechanics, software development, and dynamic systems to optimize every phase of flight. You'll develop flight algorithms, simulate trajectories, and model Terran R's dynamic behavior across mission profiles. Whether you're early in your career or a seasoned expert, you'll have the opportunity to own critical pieces of the system, influence design, and see your work fly. The department is part of the Integrated Performance team, uniting key disciplines to drive performance at every stage of the mission.
About the Role:
  • You will be a key contributor to the 6DOF simulation used for GNC algorithm development, Monte Carlo analysis, and hardware-in-the-loop (HITL) testing
  • Work with analysis and hardware teams to develop and integrate subsystem models into the 6DOF simulation
  • Implement numerical solvers and physics models
  • Develop simulation configuration, scheduling, logging, and Monte Carlo capabilities
  • Develop simulation interfaces with GNC algorithms
  • Maintain and improve the development environment for simulation users
  • Contribute to other cross-functional software packages at Relativity

About You:
  • An undergraduate or graduate degree (BS/MS/PhD) in engineering, physics, mathematics or related disciplines
  • 2+ years of relevant full-time work experience
  • Proficiency with compiled (e.g. C++, Rust) and scripted (e.g. Python) languages
  • Experience developing physics-based simulations of aerospace vehicles
  • Ability to work in a fast paced and intense startup environment
  • Ability to complete projects with ownership of end-to-end solutions with a high degree of independence

Nice to haves but not required:
  • Familiarity with the design and analysis of launch vehicles or space systems
  • Experience developing aerospace vehicle simulations that interface with GNC algorithms and/or hardware-in-the-loop (HITL) testing
  • Experience implementing high-performance computing (HPC) solutions
  • Experience implementing software development practices and workflows such as Docker, continuous integration (CI), and continuous deployment (CD)

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.
Hiring Range:
$126,000-$188,000 USD
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
If you need a reasonable accommodation, please contact us at
Please note: Relativity Space does not accept unsolicited resumes, candidate profiles, or referrals from recruitment agencies or search firms. Any unsolicited submission - via email, our website, social media, or directly to an employee - will be deemed the property of Relativity Space, and no fee will be owed absent a current, fully executed agreement with Talent Acquisition that specifically authorizes submissions for the applicable role.
