Job description

As a Thermal Mechanical Engineering Intern, you will help develop an active thermal control unit for CubeSat-class spacecraft. The unit uses a Thermo-Electric Cooler (TEC / Peltier element) to provide both heating and active cooling, enabling precise temperature control for space hardware. You'll work in a hands-on engineering environment where you can move quickly from concept and interfaces to prototypes, testing and iteration-together with thermal, electrical and mechanical engineers.

What you'll do

• Contribute to the mechanical development of a TEC-based thermal control unit.

• Support trade-offs and design decisions around interfaces, mounting, packaging, and integration.

• Help translate thermal/electrical requirements into practical mechanical solutions (materials, conduction paths, assembly approach).

• Support prototype manufacturing: preparation of parts, assembly support, coordinating practical build steps.

• Set up and support testing activities (test setups, instrumentation support, executing tests, capturing results).

• Assist with documenting designs and tests (engineering notes, configuration updates, test reports and handover material).
