Principal Mechanical Engineer

A bit about us:

We are partnering with one of the fastest-growing companies in the commercial space industry. Our client is redefining how satellite constellations are designed, built, and deployed by combining cutting-edge spacecraft technology with a mission-driven approach to delivering real-world impact from space.

Founded by industry veterans from leading aerospace and satellite organizations, the company has rapidly grown into a team of over 200 engineers, scientists, and innovators focused on building next-generation space infrastructure. Their technology is already supporting critical missions and helping accelerate the future of Earth observation, environmental monitoring, and space-based intelligence.

This is an opportunity to join a company that is actively designing, building, and launching spacecraft-not simply planning for the future.

Why join us?

Own major spacecraft systems from concept through launch
Help shape the future of satellite constellation development
Work alongside engineers from top aerospace and technology companies
Influence architecture decisions, not just individual components
Join a high-growth company with significant momentum and active flight programs
Competitive compensation and meaningful equity participation
Relocation assistance available
Comprehensive healthcare coverage and generous PTO

If you're looking for a role where your work directly impacts what gets built, tested, launched, and operated in orbit, this is that opportunity.
