About The Position

Echodyne is seeking a Senior Test Engineer to focus on On-Radar Firmware. This role involves designing, executing, and maintaining feature-level and end-to-end software test scenarios for complex embedded systems, radar firmware, and SDKs. The engineer will analyze product requirements and architecture to define test strategies, coverage, and acceptance criteria for radar functionality and supported commands. Responsibilities include developing and maintaining test plans, test cases, and test reports, managing defects through resolution, and performing manual, exploratory, and hardware-in-the-loop (HIL) testing. Building and maintaining automated tests, collaborating with firmware, product, and software teams, supporting test environments, and mentoring junior engineers are also key aspects of this position.
