<h2>About Base</h2>Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.<h2>About the Role</h2>We are seeking a Functional Test Design Engineer to own the design, maintenance, and continuous improvement of end-of-line (EOL) functional testers for high-volume electromechanical assemblies. This is a hands-on EE role spanning the full range of test development—from standing up a prototype tester in two weeks to optimizing a high-volume station that is bottlenecked on cycle time.
