Functional Tester Design Engineer

About the Company

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.

Responsibilities

• Own day-to-day support of EOL functional testers on the production floor, including debugging failures and analyzing yield.
• Perform EE design for functional testers, including schematic capture, PCBA design, fixturing, and harnessing.
• Develop and maintain functional test software, primarily in Python on Linux.
• Select and integrate measurement instrumentation such as DAQ, programmable loads, source meters, and sensors.
• Ensure accurate test data capture and reliable upload to test databases for traceability.
• Collaborate with hardware, firmware, and manufacturing teams to define test coverage and resolve issues.

Requirements

• 2–5 years of experience designing functional or end-of-line testers for electromechanical assemblies.
• Strong EE fundamentals in hardware design (schematics, PCBA, fixturing, power, and interconnect).
• Proficiency in Python on Linux for test automation and instrument control.
• Hands-on experience with DAQ systems, programmable loads, source meters, and digital comms (CAN, serial).
• Solid grasp of functional test methodology and debugging skills across hardware, firmware, and software.

Preferred Qualifications

• Experience optimizing high-volume testers for cycle time and throughput.
• Familiarity with test data infrastructure and databases.
• Experience interfacing a variety of sensor types in a test context.
• Background in reducing false-reject rates and improving yield through fixture improvements.
