Lead capability/feature development of the HIL Software Infrastructure to enable all of Epirus software/QA to validate functionality. Develop user interfaces which enable technicians to run tests and troubleshoot failures. Coordinate with other engineers on designing and setting up new test fixtures, typically on lab benches or in RF chambers (also occasionally out in the field). Coordinate with hardware and software teams to develop Hardware‑in‑the‑Loop test platforms and procedures and automations. Work with other engineers to develop new test scripts/programs, maximizing code reuse for consistency of testing. Manage ever‑growing data logging and analysis, to power data‑driven decisions. Coordinate with Manufacturing team and train technicians on operation of test software for production testing. Coordinate with Test Hardware team on HIL design and HIL Software needs. Selection and onboarding new lab equipment/instrumentation, such as various sensors, DAQs, etc., to continually improve HIL capabilities.
