Job description

Katalyst Description: Katalyst is an American technology company focused on dynamic space operations. We are building a fleet of dual-use multipurpose robotic space vehicles to create the future where maneuvering, upgrading, refueling, resupply 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 exploration 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 • Help create models and sims for cross domain uses • Learn how to convert data sheets into code • Aid the team in creating AI&T testing tool suite to aid in SITL testing • Maintain and create coding environment • Verify model and sims against hardware What We’re Looking For Required • 1-3 Years of experience in modeling and simulation for complex aerospace missions • 2-3 years working in C++ and Python • Strong understanding of object-oriented software development practices • Ability to understand new challenges quickly, formulate a plan, get buy-in, and execute • Understanding complex distributed systems, and how the components you design and deliver will fit into those larger systems • Excellent problem-solving skills and attention to detail • BS in Aerospace Engineering, Physics, Computer Science or closely related STEM field Your Ideal Background Preferred • Experience simulating in 6-DOF relative motion and RPOC • Contributed to previous digital twin efforts • Working knowledge in multiple at least one subsystems such as GNC, Flight Dynamics, EPS, Propulsion, etc • Previous experience in simulations frameworks such as Basalisk, STK, GMAT • Working knowledge of distributed compute frameworks 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 $90,000 - $125,000 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. You will also receive access to comprehensive medical, vision, and dental coverage, and unlimited Paid Time Off. 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.
