Job Description 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 processes that go into developing 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. Getting the process engineering right is not a support function here; it is on the critical path. You will define how K2 selects, qualifies, and scales manufacturing processes for its solar array systems. 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 and novel manufacturing processes in the development and scaling of K2's solar array design and production. Responsibilities • Responsible for the development, qualification, and production-scale optimization of K2's solar array processes — including solar module interconnects, bonding, sintering, lamination, deposition, coating, bonding, mechanism joints, and surface treatment, • Research, evaluate, and select conventional and novel processes for solar array applications, driving trades that balance performance, manufacturability, cost, reliability, and schedule, • Design and execution of structured DOE and statistical analyses to diagnose manufacturing problems and validate corrective actions, • Use a first-principle, physics-based characterization across production processes to identify sources of variation and opportunities for yield improvement, • Lead failure analysis, defect characterization, and root causes investigations for process related anomalies, • Establish and drive corrective action plans back into design requirements and production, • Own the evaluation, cost/benefit analysis, and selection of manufacturing equipment for all in-house process development, • Collaborate with the production team to develop process specifications, work instructions, in-process checkouts, and end-of-line tests, • Define qualification criteria, test envelopes, and characterization campaigns to establish resultant performance across radiation, thermal cycling, mechanical, and plasma environments, • Partner with solar structures/mechanisms, thermal, avionics, and production teams to define manufacturing process-driven requirements, integrated qualification/acceptance testing, and on-orbit data review, • Collaborate with leadership on staffing plans, role definitions, and recruiting efforts to ensure the solar array team is appropriately staffed to meet system deliverables, • Bachelor's degree in materials science, chemical engineering, mechanical engineering, physics, aerospace engineering, or a related technical discipline, • 8+ years of experience in materials and process engineering, with demonstrated depth in material selection, characterization, qualification, and production-scale process development, • Master's degree or PhD in materials science, chemical engineering, or a related field, • Prior experience architecting manufacturing processes for solar array systems across the full development lifecycle — requirements definition, trade studies, development testing, qualification, production, and on-orbit data review, • Hands-on experience across multiple solar array material systems, with variation in cell technology, interconnect methodology, encapsulant chemistry, and system architecture, • Deep working knowledge of adhesive systems, composites, thin films, thermal interface materials, and coatings as applied to high-power, long-life solar array hardware, • Working knowledge of AIAA S111/S112, SMC-S-016, NASA-STD-4005, NASA-STD-5017, and NASA-STD-6016 for solar module qualification, materials usage, and spacecraft charging effects, • Understanding of radiation effects on solar cell and module materials — displacement damage dose modeling, ionizing effects, UV degradation, and atomic oxygen erosion, • Depth across solar process disciplines including deposition techniques for anti-reflective coatings, chemical etching for bond preparation, encapsulant deposition, methods for corrosion control, outgassing compatibility, descriptive and inferential statistics, and failure analysis., • Hands-on proficiency with material characterization tools: SEM, EDS, FTIR, DSC, TGA, XRD, or equivalent, • Experience scaling manufacturing processes from prototype to high-rate production, including SPC implementation and manufacturing equipment qualification, • Base salary range for this role is $175,000 - $200,000 + equity in the company, • Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level 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).
