In this role, you will be responsible for executing design verification and validation testing at the component, board, and system level for our AMU hardware. Physically, the AMU PCBA sits inside the AMU Panel assembly along with the HIgh Voltage DC Shunt board which is responsible for measuring efficiency of our system, UPS, and PSUs. It acts as a critical zone controller responsible for communication, network security, high-voltage/high-current sensing, power distribution, actuation, safety/fault management, and UPS management. You will ensure that AMU electronics meet stringent functional, reliability, safety, and compliance requirements through structured test campaigns. You'll collaborate closely with hardware, firmware, and systems engineers to validate designs that are central to the safe and reliable operation of our multi-megawatt battery systems.This is an exciting opportunity to contribute to the scaling of our battery technology and be part of the growth of a fast-moving company with breakthrough technology and an incredible mission! Relocation assistance is available. What you'll do: * Test Strategy & DVP: Develop comprehensive test plans, DVP&Rs, and verification protocols for the AMU PCBA and its integrated panel assembly components. * Communication Protocol Verification: Validate safety-critical and non-safety communication interfaces including CAN-FD (to ZMUs), Ethernet (to ZMUs and upstream QMU), and dedicated RS485 (for UPS management). * Sensing Subsystem Validation: Design and execute test setups to verify precision sensing capabilities: Pack HV voltage (-1 to 1600V via HVDC Shunt resistor divider), Pack HV current (-500A to 500A via shunt R4), 48V PSU/UPS monitoring (0-60V), 48V total current draw (0-40A), and auxiliary temperatures. * Actuation & Power Distribution: Verify HV contactor control (pack connect/disconnect), heater SSR control, and power routing from dual 48V PSUs and the 48V UPS down to the ZMUs. * Safety & Fault Management: Rigorously test Hardware Over-Current Protection, fault loop logic, and Functional Safety (FuSa) testing. * Data Analysis & Root-Cause: Analyze test data, generate detailed reports, and collaborate with design engineers to root-cause board or firmware anomalies found during testing. * Test Automation: Contribute to test automation frameworks (utilizing Pytest) to optimize repeatability and scale verification throughput. ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [pytest: Simple, rapid and fun testing with Python](https://www.wearedevelopers.com/videos/213-pytest-simple-rapid-and-fun-testing-with-python) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) ## Related Articles - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
