About the Role

Miuan seeks a Senior Mechanical Engineer to join our team. The ideal candidate can dive deep on design and analysis while bringing a systems mindset and will be a force multiplier collaborating with other disciplines to arrive at an elegant, well-balanced design. Being an early-stage startup with a small team, breadth is extremely important and we expect this person to dive into structural data, dynamics, thermal design, supplier management and everything else associated with the full lifecycle of an electromechanical product. On-site work at our Mountain View location is required.

Responsibilities

  • Create, review, and refine spacecraft mechanical design with product structure in a modern CAD package (Solidworks).
  • Ownership of delivery of mechanical vehicles and subsystems, acting on multidisciplinary designs between launch provider, analysts, avionics, program, thermal, optical, and RF engineers.
  • Find solutions and manage development of clean-sheet mechanical/structures architectures through detailed design consistent with risk posture, development velocity and deployment schedules at Muon.
  • Make economically sound choices balancing rapid demonstration of capability while understanding the path to scaled-up constellations (Make vs Buy).
  • Create quick concepts to spur inspiration on the team in early phases of programs.
  • Perform basic stress and dynamic analyses (hand calcs, simple FEM) to support and inform structures designs including joint design, basic stiffness analyses.
  • Contribute to maturing Muon's mechanical engineering standards and culture.
  • Design test fixtures to support development and environmental testing.
  • Influence flight designs to ensure hardware is easy to build and test.
