2d64a465-391 Senior Mechatronics Test Engineer As a Senior Mechatronics Engineer at Astranis, you will be responsible for developing, designing, and implementing tests and test systems for all the custom mechanisms on our spacecraft. You'll prove that our suite of mechanism designs work across environments to guarantee success on orbit through rigorous tests on the benchtop and in environments (thermal, vacuum, vibe).

Develop and design automated hardware and software solutions to test+validate mechanism hardware, interfacing with motors and controllers. Write software in Python to control bench equipment, devices under test, and other test hardware. Design and own testing racks used to develop, prototype and qualify mechanisms. Work closely with the design team to provide feedback and insight through prototyping and qualification process. Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.

Our ideal candidate has a B.S. degree in mechatronics, electrical or computer engineering, or equivalent technical degree, and 4+ years of relevant experience. A passion for hardware development, including working in a fast-paced environment and hands-on design and development, is essential. Comfort with ambiguity and turning high-level requirements into clear design/test objectives is also required. Hands-on experience using electrical test equipment and interfacing with mechanical hardware is necessary. Experience using Python is also required.

Bonus skills include understanding and experience in environmental testing such as vibration, shock, thermal, burn-in, and TVAC, mechatronics experience using hardware such as motors and mechanisms, experience with CAD software, experience with designing and building electrical harnesses and connectors, and experience automating tests, test equipment, or similar instrumentation.
