Materials & 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 M&P engineer for our satellite bus structures, mechanisms, thermal, electrical, and solar array systems, including adhesives, sealants, cover glass and coatings   Partner with experienced M&P 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 M&P 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 M&P 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 in material selection, characterization, qualification, and production-scale process development   Demonstrated track record of material and process decisions that have been validated through flight or equivalent high-reliability hardware programs   Nice to Have   Master's degree or PhD in materials science, chemical engineering, or a related field   Experience architecting M&P programs for solar array systems across the full development lifecycle — requirements definition, trade studies, development testing, qualification, production, and on-orbit data analysis   Background working across multiple solar array material systems with variations in  cell  technology, interconnect metallurgy, encapsulant chemistry, and substrate architecture   Deep understanding of adhesive systems, composites, thin films, thermal interface materials, and coatings as applied to high-power, long-life solar arrays   Familiarity with AIAA S111/S112, SMC-S-016, NASA-STD-4005, NASA-STD-5017, and NASA-STD-6016 for the qualification of solar modules, materials usage, and spacecraft charging effects   Experience with radiation effects on  solar materials , including displacement damage dose modeling, ionization effects, UV degradation, and atomic oxygen erosion   Expertise in key M&P disciplines including fracture mechanics, corrosion control, fluid/outgassing compatibility, descriptive and inferential statistics, and failure analysis   Proficiency with material characterization techniques and tools (SEM, EDS, FTIR, DSC, TGA, XRD, or equivalent)   Experience scaling material processes from prototype to high-rate production, including SPC implementation and manufacturing equipment qualification   Familiarity with manufacturing processes including soldering, wire bonding, welding, lamination, heat treatment, plating, conversion coatings, and surface modification   Python or MATLAB proficiency
