What is space science?

Space science is the study of everything in outer space, including planets, stars, galaxies, and the physics that governs them. It encompasses disciplines such as astronomy, astrophysics, planetary science, and space exploration. Professionals in this field use telescopes, satellites, and spacecraft to observe and analyze celestial phenomena. Space science helps us understand the origins of the universe, the possibility of life elsewhere, and the future of space exploration.

What are space science careers?

There are a wide variety of space science careers to choose from that involve all aspects of studying the earth, atmosphere, other planets, and the exploration of the universe. NASA provides many employment opportunities aside from becoming an astronaut. As a space scientist, you conduct research and studies in a specialty field such as biology, chemistry, meteorology, physics, geology, or even pharmacology, in which you use substances from space to develop new medications. Engineers have responsibilities including developing advanced technology such as satellites and the spacecraft that make space exploration possible. Specialties as an engineer include robotics, telecommunication, computers, avionics, instrumentation, and more. There are also technologists and technicians whose duties revolve around working with the engineer to test this technology.

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

To thrive as a Space Scientist, you need a strong background in physics, mathematics, astronomy, and often a Ph.D. in a related field. Familiarity with data analysis software, satellite instrumentation, programming languages like Python or MATLAB, and experience with telescopic and spacecraft systems are typically required. Analytical thinking, problem-solving, teamwork, and effective scientific communication are vital soft skills. These competencies enable Space Scientists to conduct meaningful research, interpret complex data, and collaborate on missions that advance our understanding of the universe.

What are some common challenges faced by space scientists when working on research projects?

Space scientists often encounter challenges such as limited access to specialized equipment, strict project timelines, and the need to collaborate with multidisciplinary teams across different organizations or countries. Additionally, securing funding for research and navigating the complexities of data analysis from space missions can be demanding. Adaptability, strong communication skills, and perseverance are important for overcoming these obstacles and successfully contributing to scientific advancements in the field.

Is space science a good career?

Space science is a specialized field that involves studying celestial bodies, astrophysics, and space technology, often requiring advanced degrees such as a master's or Ph.D. Skills in mathematics, programming, and data analysis are important, and employment can be found in research institutions, government agencies, and aerospace companies. The career can be competitive but offers opportunities for contributing to scientific discovery and technological innovation.

What jobs are there in space science?

Space science offers a variety of careers including astrophysicist, planetary scientist, aerospace engineer, mission analyst, and space technician. These roles often require strong backgrounds in physics, engineering, or astronomy, and may involve working with telescopes, spacecraft, or data analysis tools in research institutions, government agencies, or private companies.

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 Interplanetary Sciences Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster, more affordable, and more capable than ever before by rethinking how science missions are designed, built, and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration, we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge, broadens participation, and inspires the next generation of explorers.

About the Role:

As a Senior Flight Software Engineer within the Interplanetary Sciences Program at Relativity Space, you will take ownership of the design, development, and deployment of flight-critical software that governs how our spacecraft behaves and operates from concept through flight.

You will be responsible for building robust, reliable embedded software that enables autonomous deep-space missions and real-time spacecraft control. This role requires an engineer who thrives on full-system ownership, moves fluidly between architecture and implementation, and brings rigorous engineering discipline to every phase of development from requirements capture to operational flight support.

Essential Duties and Responsibilities:

  • Design, implement, and test flight software for spacecraft command, control, and autonomy across all mission phases
  • Own full lifecycle software development: requirements capture, architecture, design, implementation, integration, test, and flight operations support
  • Collaborate with avionics, GNC, propulsion, and mission operations teams to ensure seamless integration between software and spacecraft hardware
  • Develop and execute verification and validation (V&V) processes to ensure flight safety, reliability, and mission success
  • Support on-vehicle and hardware-in-the-loop (HIL) testing, debugging, and mission simulations

About You:

  • Bachelor's or Master's degree in Computer Science, Aerospace Engineering, Electrical Engineering, or a related technical field
  • 5+ years of experience developing, testing, and delivering embedded or real-time flight software
  • Strong proficiency in C++ and solid understanding of memory management, concurrency, and embedded systems design
  • Experience with RTOS or Linux-based embedded development, software integration, and system-level testing
  • Proven ability to scope open-ended problems, execute autonomously, and deliver high-quality, flight-ready software
  • Ability to work effectively in a collaborative, fast-paced team environment, demonstrating adaptability and problem-solving skills

Nice to haves but not required:

  • Experience developing software for spaceflight, launch vehicles, or planetary spacecraft
  • Familiarity with deep-space communication protocols and autonomy frameworks
  • Experience with Python or Rust for tooling, testing, or simulation support
  • Background in hardware-in-the-loop testing, embedded networking, or fault-tolerant system design
  • Knowledge of NASA or other aerospace software development and verification standards, applied in a modern new-space context

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.
