Senior Mechanical Assurance 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 We’re building a modern, lightweight Quality function for a fast-moving aerospace/defense startup. If you love making mechanical hardware trustworthy—from early designs to flight-ready builds—this role gives you the runway to set direction, solve tricky problems, and help teams move faster with confidence. Responsibilities Support translation of system and customer needs into clear mechanical requirements, risk assessments, and test plans Review models, drawings, and tolerance stacks to ensure fit, function, and critical feature protection (GDT compliance). Collaborate with design and MP teams on material/process selection and qualification strategies. Flow requirements into practical work instructions and inspection plans; establish process capability using SPC/MSA and control plans. Lead nonconformance management and drive durable corrective actions. Assess and audit supplier capability; manage APQP/PPAP deliverables and SCARs Develop and track quality metrics and apply analytics to predict risks. Align with AS9100/AS9145 standards while improving QMS for efficiency. Represent the team confidently during customer audits and visits.
