The Mechanical Engineer is responsible for owning the mechanical design and analysis from concept through flight, working closely with electrical/RF engineers, systems engineers, and program management to deliver flight hardware that survives launch and performs in the space environment. This is a hands-on, high-ownership role for someone who wants to see a design through its full lifecycle from early trade studies and requirements, through analysis, drawings, fabrication, test, and flight.

The position reports to the Mechanical Engineering Manager and is part of the Engineering department based in San Diego, CA. This role is 100% onsite.

• Own hardware through its full lifecycle — from concept and requirements through design, analysis, build, test, and delivery.
• Design mechanical enclosures, structures, systems, and mounting solutions for spacecraft hardware.
• Perform structural and thermal analysis to verify design margins against launch loads, on-orbit thermal environments, and mission requirements.
• Generate detailed part and assembly drawings suitable for fabrication and inspection.
• Collaborate closely with electrical and RF engineers on PCB layout, packaging, and mechanical-electrical integration.
• Develop manufacturing instructions and work with fabrication/assembly technicians to build flight and engineering hardware.

• Strong understanding of engineering fundamentals: statics, dynamics, heat transfer, structural mechanics, materials, and fabrication.
• An excellent communicator and proficient in development and delivery of presentations across a range of settings, including formal design reviews.
• Experience with FEA (SolidWorks, Ansys, or similar) to validate structural, thermal, vibrational, performance against program requirements.
• 3D CAD proficiency in SolidWorks and ability to understand and apply GD&T per ASME-Y14.5 to create high-quality engineering drawings.
• Understanding of machining and mechanical assembly as it impacts design.
• Experience writing manufacturing instructions.
• Highly motivated, self-starting, and able to perform duties autonomously without supervision.

• Experience integrating electronic components (PCBAs, motors, sensors etc.) into mechanical designs for space or military applications.
• Structural or thermal testing experience – TVAC, thermal cycling, random vibration, shock.

• Must be a U.S. citizen with the ability to obtain and maintain a U.S. government security clearance
