Mechanical Engineering Senior

A VC-funded, early-stage space technology startup in Seattle is developing next-generation Geospatial Intelligence technology , centered around a proven and scalable electronically steered radar architecture. The technology supports sophisticated spaceborne applications including Earth observation using Synthetic Aperture Radar (SAR), alongside advanced defense applications such as ground and airborne target tracking. We are looking for a Senior Mechanical Engineer to take ownership of the full lifecycle development of electromechanical hardware for a spaceborne radar payload . This is a highly hands-on position for an engineer who enjoys taking hardware from requirements and initial design through fabrication, integration, testing and environmental qualification.

requirements definition through design, fabrication, test and qualification Develop rugged PCB assemblies, avionics enclosures, RF hardware, power-system packaging and mounting solutions for harsh environments including Low Earth Orbit Perform engineering analysis including bolted-joint, modal/vibration, static and dynamic thermal analysis and tolerance stack-ups Develop organized, configurable and production-ready 3D CAD Produce engineering drawings in accordance with ASME Y14.5-2018 Design hardware capable of successfully completing demanding environmental qualification programs Make informed cost, schedule and performance trade-offs across manufacturing processes including CNC machining, PCB manufacturing, additive metal manufacturing, Wire EDM, electroforming and injection molding Support payload development and spacecraft integration while managing technical and schedule dependencies Work closely with electrical, RF, thermal, manufacturing and systems engineering teams Mentor junior engineers and contribute to a culture of technical excellence, innovation and ownership
