Muon seeks a Principal Mechanical Engineer to join our Mechanical Engineering team. This role focuses on leveraging deep space industry experience to optimize and mature our existing spacecraft designs while mentoring and developing our mechanical engineering team.
As a Principal Engineer, you will apply your extensive flight heritage to enhance Muon's current spacecraft architectures, driving improvements in performance, manufacturability, and reliability. You'll serve as a technical leader and trusted advisor across the organization, using your expertise to guide critical design decisions and establish best practices that scale with our growing constellation production.
The ideal candidate brings proven space hardware experience and a passion for developing others. You'll be a force multiplier—someone who elevates the entire team through hands-on mentorship, rigorous design reviews, and the establishment of standards that capture lessons learned. You have a "systems mindset" and can balance optimization of existing designs with strategic thinking about long-term product evolution.
This is a Principal-level (L7) individual contributor role focused on technical leadership and mentorship, potentially including some people management.
Due to the hands-on nature of this role, it does require onsite work at our Mountain View and San Jose locations.
The salary range for this role is $239,000 - $260,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
Founded in 2021, Muon Space is an end-to-end Space Systems Provider that designs, builds, and operates LEO satellite constellations delivering mission-critical data. Our revolutionary, integrated technology stack enables customers to optimize every dimension of their missions for faster time-to-orbit and superior constellation remote sensing performance. Our state-of-the-art facility in the heart of Silicon Valley is optimized for manufacturing spacecraft and rapid, flexible payload integration at scale.

At Muon salary is only part of our total compensation package. In addition to salary, full-time employees receive equity compensation as well as benefits including medical, dental, and vision insurance, a 401k retirement plan, short & long term disability and life insurance. We also offer three weeks paid vacation for new employees, along with 12 paid holidays, unlimited sick time and paid parental leave.
