You will work closely with other engineers (including electrical, mechanical, and software) to derive test requirements and develop the corresponding test infrastructure and processes. You are passionate about autonomous vehicle development and will bring that enthusiasm to solving challenging problems in pursuit of a reliable and scalable testing ecosystem. As an early employee at a fast-moving startup, you will work on a multitude of technical projects and help shape the direction of the company., * Design and maintain test solutions for in-house developed electronics components and systems * Build and maintain test benches used for development and software regression testing * Define and develop test cases using Python * Produce documentation for testing including test plans, work instructions, design drawings, and test reports * Support testing and data analysis to identify and root-cause issues * Test vehicles at Parallel test facilities and customer sites * Mentor other engineers and contribute to the team's technical growth What Success Looks Like: * After 30 Days: You're familiar with vehicle and subsystems, including functional requirements and testing. You've produced design drawings for a test bench and procured parts. * After 60 Days: You've integrated a test bench and demonstrated functionality and ability to meet test needs. * After 90 days: You've automated test bench operations and integrated into software regression testing. You're supporting ongoing testing and driving an outcome tied directly to a business objective as a trusted partner.
