About The Position

Parallel Systems is developing autonomous battery-electric rail vehicles intended to shift portions of U.S. freight transportation from trucking to rail. The Hardware Test Engineer II validates the performance of these vehicles and their subsystems, working with electrical, mechanical, and software engineers to derive test requirements and build the associated test infrastructure and processes. The role contributes to a reliable, scalable testing ecosystem and spans a range of technical projects at an early-stage company.

The engineer designs and maintains test solutions for in-house electronics, builds and supports test benches for development and software regression testing, develops Python test cases, and creates test documentation. The position also supports testing and data analysis, identifies root causes of issues, tests vehicles at Parallel facilities and customer sites, and mentors colleagues. Success in the first 90 days includes learning the vehicle and subsystem requirements, designing and integrating a test bench, automating its operation, and supporting regression and ongoing testing.

Requirements
