Job description

We build robotic spacecraft that enable dynamic space operations, creating a future where maneuvering, upgrading, refueling, and exploration are as routine as they are on Earth. Getting to space and overcoming the gravity well is only half the story. What you do there is the future. We are not building the trains. We are building the machines that lay down the tracks. By developing the foundational capabilities that make sustained, responsive operations possible, we enable a new era of space activity that strengthens national security and ensures freedom of action in an increasingly contested domain.

Katalyst Culture

Working at Katalyst is intense, hands-on, and deeply rewarding. You’ll take real ownership and see your work move from concept to operations in an environment where the problems are hard and the impact is real. We value humility, craftsmanship, and doing things the right way, even when it’s harder. You’ll work closely with thoughtful, driven teammates who push each other to do their best.

What You’ll Do

• Supporting GNC algorithm trade studies
• Building simulation environments and prototype algorithms
• Collaborating on system-level integration
• Developing and validating 6-DoF simulation tools
• Assisting with datasets and algorithm evaluation
• Supporting implementation, testing, and debugging

Your Ideal Background

Required

• Bachelor’s degree in relevant engineering field
• 3+ years of experience working in guidance, navigation, and control in one or more areas:
• Modeling and simulation
• Trajectory or path planning
• Classical or modern control of dynamical systems
• Software development experience in Python for modeling and simulation applications
• Experience with GNC systems, sensors, or control algorithms
• Ability to work in fast-paced startup environment
• Strong problem-solving skills
• Experience with space system development, especially around guidance, navigation and control, or rendezvous proximity operations.
• Orbital mechanics / Astrodynamics knowledge
• Git, Linux, Basilisk familiarity C/C++ experience
• Real-time embedded systems experience
• Spacecraft hardware knowledge (RWAs, thrusters, etc)
• Mission operations experience

Additional Requirements: Must be willing to work extended hours and weekends as needed.

Compensation and Benefits: Your base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. The anticipated salary range for this role is $140,000 - $240,000 annually.

Base salary is just one part of your total rewards package at Katalyst. You will also be eligible for long-term incentives, in the form of the Employee Stock Option and Equity Plan, as well as a relocation bonus and other discretionary bonuses.

At Katalyst our work on projects involving the U.S. Department of Defense requires adherence to International Traffic in Arms Regulations (ITAR), 22 C.F.R. Parts 120-130, which requires compliance with U.S. export laws before allowing employees to perform certain positions. Currently, our available roles necessitate access to ITAR-controlled information, and as a result, Katalyst would have to ensure any non-US person is authorized access to ITAR information before the commencement of employment. We are committed to equal employment opportunities and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, or national origin.
