Are you passionate about shaping the future of humanity's presence in space? Lunar Outpost, a trailblazer in space robotics, invites you to join our team! Lunar Outpost is dedicated to creating a sustainable presence in space, while also driving positive impacts here on Earth. We are seeking a talented, experienced Senior Systems Engineer - Thermal to help define the future of lunar surface mobility in a fast-paced startup environment. The main responsibilities for this role will be to help supervise requirements management, standards compliance, verification, validation, and testing activities, to define/contribute to and maintain subsystem interfaces, and to serve in a technical oversight role for vendors and subcontractors working on the thermal system. 

Take the #NextLeap with Lunar Outpost and work on the Pegasus LTV, which will carry NASA astronauts farther than they've ever been before on the lunar surface!

Key Responsibilities:

• Support the Thermal IPT Lead in defining and maintaining thermal subsystem requirements, including allocation, traceability, and verification planning

• Develop and maintain interface definitions (ICDs) between thermal hardware and spacecraft subsystems (structures, avionics, propulsion, EPS)

• Coordinate with Thermal Analysis, Mechanical Design, and Systems Engineering to ensure design closure and requirements compliance

• Contribute to verification & validation (V&V) planning, including definition of test methods, success criteria, and requirement mapping

• Develop and execute thermal test plans (component, subsystem, and vehicle-level), including thermal balance and TVAC campaigns 

• Support integration and test (I&T) activities, including instrumentation planning, test setup definition, and data review

• Generate and maintain engineering documentation (ICDs, test plans, procedures, verification matrices)
