About The Position

As a Test Engineer in Antares’ Test Engineering team, you will design, build, and own test infrastructure for our R1 microreactor. You will develop end-to-end test plans - from concept to data analysis - for components and subsystems spanning heat rejection, power distribution, thermal management, and mechanical systems. You will help develop and document our testing best practices, requirements, and workflows to enable rapid iteration and high-quality data. You will collaborate with cross-functional teams to ensure that prototype, development, and qualification hardware is designed with respect to a test plan that validates critical features and performance parameters. You will design, validate, and maintain test setups to ensure the required precision and accuracy.
