Senior Solar Process Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M 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. The Role The materials that go into K2's solar arrays — from module interconnects and adhesive systems to cover glass coatings and substrate composites — directly determine how much power they produce, how long they last, and how fast we can build them. Collaborating across the engineering and production teams, you will own the success of the materials selections and their implementations that will be key to our successful satellite operation. You will define how K2 selects, qualifies, and scales materials and processes for its solar array systems and other subsystems. The operating environments, mission lifetimes, and production rates we are pursuing demand meaningful impact in how our materials are characterized, qualified, and manufactured. You will own the success of implementation of material systems in the development while scaling of K2’s solar array design. Responsibilities Serve as a Responsible MP engineer for our satellite bus structures, mechanisms, thermal, electrical, and solar array systems, including adhesives, sealants, cover glass and coatings Partner with experienced MP engineers to help define the strategy and qualification philosophy for satellite materials spanning LEO to deep space mission environments Research, trade, and select conventional and novel materials and processes for various novel applications Define qualification criteria, test envelopes, and characterization campaigns that establish material performance margins across radiation, thermal cycling, mechanical, and plasma environments Lead design reviews, continually own system-level MP deliverables, and drive development schedules with accurate projections looking 12+ months ahead Collaborate with solar, structures/mechanisms, thermal, avionics, and production teams to define material-driven requirements, integrated qualification/acceptance testing, and on-orbit data review Lead failure analysis and root cause investigations for material-related anomalies, establishing corrective action processes that feed back into design and production Evaluate, qualify, and manage material suppliers, including incoming inspection criteria, lot acceptance requirements, and supply chain risk mitigation Auth or, implement, and maintain MP requirements, material and process specifications, technic al specifications, and engineering work standards related to solar array materials and others used on throughout the spacecraft Qualifications Bachelor's degree in materials science, chemical engineering, mechanical engineering, physics, aerospace engineering, or a related technical discipline 2+ years of experience in materials and process engineering, with demonstrated depth ...
