Electrical Test Engineer

A large defense technology client is seeking a dedicated Electrical Test Engineer to sit onsite in Costa Mesa, CA. This role involves taking board-level designs developed by hardware design engineers and owning the test planning, execution, and analysis needed to validate performance across electrical and thermal conditions.

The Electrical Test Engineer will work hands-on with complex PCBAs used in aerospace, UAV, and automotive systems. This position requires strong electrical fundamentals, schematic-level understanding, and the ability to diagnose failures through detailed signal analysis and data-driven testing. This role fills a critical gap between design engineering and production by providing deeper engineering-level test expertise beyond technician capabilities.

We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters. Qualified candidates will receive consideration for employment regardless of their race, color, ethnicity, religion, sex (including pregnancy), sexual orientation, gender identity and expression, marital status, national origin, ancestry, genetic factors, age, disability, protected veteran status, military or uniformed service member status, or any other status or characteristic protected by applicable laws, regulations, and ordinances.
