Principal Mechanisms Engineer - Payloads

About this Role

As a Principal Mechanisms Engineer on Varda's Payload team, you will define and lead the development of complex electromechanical flight hardware that operates in orbit, endures hypersonic reentry, and returns to Earth for inspection and iteration.

You will shape payload architecture across pharmaceutical manufacturing and hypersonic reentry testbed missions-guiding systems from early concept through detailed design, integration, testing, launch, and recovery. You'll work closely with internal leadership and external partners, translating mission needs into engineering strategy and technical direction.

This role is ideal for engineers with deep mechanical expertise and broad cross-disciplinary insight who want to influence system architecture, lead multi-mission efforts, and mentor engineers while delivering complex hardware on rapid flight timelines.
