About the Role

<div class="content-intro">K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by <a href="https://www.forbes.com/sites/aliciapark/2025/12/11/this-startup-is-building-huge-satellites-for-an-underused-interstellar-sweet-spot/?ctpv=searchpage">$450M</a> from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.  The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.  With multiple launches planned through 2026 and 2027, we're Building Bigger 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 C space startup, we’d love for you to apply. </div>The Role You will own the success of mechanical structures and mechanisms used for a propulsion system that will be the highest-powered electric propulsion system ever flown and unlock new mission concepts and increase our access to deep space. As part of a small multidisciplinary team, your role will involve mechanical design, development, build, test, and analysis of the satellite’s plasma propulsion system and all related hardware. In your first 6 months, you will define product requirements, create initial concepts and trades, perform preliminary and detailed analysis, define development test campaigns, and produce development hardware. In your first year, you will validate your designs through prototype iterations and build and qualify flight hardware. In your first two years you will fly your hardware in space while directly supporting production and integration.   Responsibilities  <ul> <li>Own the mechanical design of propulsion system hardware including propulsion modules, critical thruster components, the propellant management system, avionics box design, propulsion secondary structures, and potentially tank development </li> <li>Validate your designs through the entire lifecycle from concept to production, and successful flight demonstrations </li> <li>Generate 3D models, fully dimensioned drawings, and interface control documents </li> <li>Perform analysis on data from testing hardware, iterating designs, and critical go/no-go calls on hardware performance </li> <li>Develop and execute component and system-level test plans </li> <li>Manage key propulsion vendors and suppliers through hardware delivery </li> <li>Continually own and refine sub-system deliverable schedules throughout development and production </li> </ul> Qualifications  <ul> <li>Bachelor’s degree in mechanical, aerospace, or other relevant engineering discipline </li> <li>3+ years of experience with mechanical and/or electromechanical design and analysis</li> <li>Experience with CAD or FEA software packages  </li> <li>Experience with the practical application of GD&T </li> <li>Demonstrated proficiency in the principles of mechanical design, materials, thermodynamics, and fluids </li> <li>Demonstrated ability to personally design, build, and test hardware from a blank canvas, including troubleshooting and iterating designs based on downstream feedback </li> </ul> Nice to Have  <ul> <li>Demonstrated ability to own mechanical hardware or systems within an integrated engineering team outside a classroom setting </li> <li>Experience in advanced propulsion technologies, including high-performance engines, in-space propulsion, and propulsion system integration </li> <li>Experience designing, building, and testing mechanical assemblies for aerospace applications (satellite mechanical systems, payloads, launch vehicles, propulsion systems, and/or aircraft structures and mechanisms) </li> <li>Deep experience in the development and qualification of high-pressure and low-pressure fluidic components, this may include flight feed system or pressurized tanks </li> <li>Demonstrated understanding of structural analysis and failure modes of complex mechanical systems in space environments and operations </li> <li>Experience with production tooling or product design in either prototype or high-volume environments </li> </ul> Compensation and Benefits:  <ul> <li>Base salary range for this role is $100,000 - $140,000 + equity in the company </li> <li>Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level </li> <li>Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks </li> </ul><div class="content-conclusion">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 with 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 <a class="c-link" href="https://www.law.cornell.edu/cfr/text/22/120.15" target="_blank">22 C.F.R. § 120.15</a> or otherwise eligible for a federally issued export control license.
