Propulsion Mechanical Design Engineer

K2 Space is building large, high-powered spacecraft for the next generation of space development. Backed by Lightspeed Venture Partners, Altimeter Capital, and many others ($200M raised to date), we intend to mass produce the highest-powered satellite platforms ever built for missions across LEO to Deep Space. The rise of launch vehicles like Falcon 9 and Starship enables the move from an era of mass constraint to one of mass abundance. We believe this new era requires spacecraft with a fundamentally different design in order to fully utilize the massive rockets coming to market. We’re a team that believes the future lies in building large, high-powered satellites that can handle multiple orbits. This is a necessity if we ever want to develop the solar system, and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series B space startup, we’d love for you to apply. The Role You will be critical to designing the hardware for a propulsion system that will unlock new achievable mission concepts and increase our access to deep space. You will own the success of propulsion hardware that will be key to the development of the highest-powered electric propulsion system ever flown. As part of a multidisciplinary team, your role will involve mechanical design, development, build, test, and analysis of the satellite’s plasma propulsion system. In your first year, you will validate your designs through prototype iterations and build and qualify flight hardware. Responsibilities Own the mechanical design of propulsion system subassemblies including critical thruster components, the propellant management system, ground support equipment, and other structural components Validate your designs through the entire lifecycle from concept to production, and successful flight demonstrations Generate 3D models, fully dimensioned drawings, and interface control documents Perform analysis on data from testing hardware, iterating designs, and critical go/no-go calls on hardware performance Develop and execute component and system-level test plans Manage key propulsion vendors and suppliers through hardware delivery Continually own and refine sub-system deliverable schedules throughout development and production Qualifications Bachelor’s degree in mechanical, aerospace, or other relevant engineering discipline 3+ years of experience with mechanical and/or electromechanical design and analysis Experience with CAD or FEA software packages Experience with the practical application of GD&T Demonstrated proficiency in the principles of mechanical design, materials, thermodynamics, and fluids Demonstrated ability to personally design, build, and test hardware from a blank canvas, including troubleshooting and iterating designs based on downstream feedback Nice to Have Demonstrated ability to own mechanical hardware or systems within an integrated engineering team outside a classroom setting (High Power Rocketry, Robotics Clubs, Formula/Baja SAE, NASA student launch etc.) Experience in advanced propulsion technologies, including high-performance engines, in-space propulsion, and propulsion system integration Familiarity with cutting-edge testing and validation techniques Deep experience in the development and qualification of high-pressure and low-pressure fluidic components, this may include flight feed system or pressurized tanks Experience with designing and qualifying avionics enclosures Knowledgeable on the thrust stands for Hall thrusters and feed system components Experience with production tooling or product design in either prototype or high-volume environments Compensation and Benefits Base salary range for this role is $100,000 - $175,000 + equity in the company Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged! If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know. Export Compliance As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult a knowledgeable advisor if you are unsure whether you are a “U.S. Person.” The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
