Senior Electronics Test Engineers II are core members of the Cesium technical team. As a member of our Test Engineering, you are responsible for the design, analysis, and implementation of engineering test plans and procedures for board‑level electronics products, including power, digital, and RF electronics. The ideal candidate possesses a strong combination of hardware and software knowledge with proficiencies in measurement techniques, test equipment, test architectures, automation, and integrated system testing. The successful candidate will work closely with multi‑disciplinary teams to address company‑wide test needs.

This role will be responsible for software products necessary throughout all phases of test and integration. Key projects will include developing and managing software for interfacing with flight hardware and test equipment in an abstract and flexible manner that can be quickly implemented into a variety of test campaigns, developing methods to store and access generated data, and equipping the test team with other software tools necessary to efficiently accomplish ambitious testing goals. Additionally, designing test solutions for flight hardware optimizing for reliability and efficiency, and developing modular, reusable test and automation software in Python (or similar languages) implemented in a variety of test applications to verify design and build quality.

A Senior Test Engineer II is distinguished by an ability to architect test systems, to draw insightful conclusions from test results, and to participate in “design for test” planning and review from the early stages of product development.
