Senior Systems Integration & Test Engineer at Tau in Redwood City, CA

Job description

• Tau is validating power electronics at the boundary between hardware, controls, software, thermal systems, and the vehicle. Failures rarely belong neatly to one discipline. The job is to design tests that expose those interactions, distinguish product problems from test problems, and turn ambiguous system behavior into defensible engineering conclusions.
• This role owns test planning and execution for Tau's power conversion products, including electric motors, onboard chargers, DC-DC converters, and power modules for EV powertrains. You'll define what "validated" means for a given program, plan and run the dynamometer, high-voltage, reliability, thermal, and vibration campaigns that prove it, and drive anomalies to root cause using Tau's existing test capability.
• You'll also be one of Tau's technical faces to the outside world. When a customer or Tier 1 partner needs someone onsite to run dynamometer testing on their floor, troubleshoot alongside their engineering team, and represent Tau's product credibly under their scrutiny, that's you.

Responsibilities

• Test strategy and planning
• Build systematic integration and test plans with clear sequencing,
• entry/exit criteria, instrumentation, configuration baselines, expected
• behavior, evidence, decision records, owners, and closure criteria
• Define the dynamometer, high-voltage, reliability, thermal, and
• vibration test campaigns needed to validate power conversion products
• against requirements
• Set technical standards for what counts as validated, calibrated, and trustworthy, including reliability and durability sign-off, and hold the work to them
• Prioritize and sequence test coverage against program risk and milestones, in collaboration with the engineers who own the design
• Test execution and analysis
• Direct and coordinate lab test operations from pre-test preparation through execution, serving as the focal point for test sequencing, anomaly response, and troubleshooting
• Run dynamometer and high-voltage test campaigns to characterize performance, efficiency, and reliability of power conversion products under real-world load conditions
• Execute reliability, thermal, and vibration testing to validate designs
• against durability and environmental requirements
• Use lab test equipment and Tau's simulation/emulation environment to set up test cases, validate system requirements, and investigate issues
• Interpret wiring diagrams and perform hands-on electrical
• troubleshooting using oscilloscopes, meters, and sensors
• Debug anomalies to root cause and feed findings back to the relevant design teams, collaborating on resolution and re-verification
• Customer and third-party support
• Provide onsite integration and test support at customer and partner facilities — for example, running dynamometer campaigns at a Tier 1 supplier and interfacing directly with their technical team
• troubleshoot jointly, answer for your test data, and translate field
• findings into corrective action back at Tau
• Coordinate test schedules and logistics across internal and external
• stakeholders when running campaigns off-site
• Cross-functional collaboration
• Partner with power electronics, controls, embedded software, and
• mechanical engineers to develop test plans and procedures
• Communicate status, risk, and anomalies clearly to the broader
• program
• Mentor other engineers, lead work breakdowns and planning, and drive
• resolution of complex, cross-cutting issues

Requirements

• 6+ years of experience in automotive system integration and test, or related field
• Bachelor's degree or higher in Electrical Engineering, Mechatronics,
• Controls, Computer Science, or a related field, or equivalent demonstrated experience
• Demonstrated experience planning and directing test campaigns, including briefing teams, managing anomalies, and making real-time execution decisions
• Experience developing test plans and procedures — sequencing, entry/exit criteria, coverage — for complex, integrated systems
• Hands-on experience with dynamometer testing and high-voltage system safety practices (lockout/tagout, interlocks, HV PPE)
• Experience with reliability, thermal, or vibration/environmental test methods
• Technical understanding of test equipment (oscilloscopes, meters, sensors) and hands-on electrical troubleshooting, including reading wiring diagrams
• Experience with MATLAB/Simulink or comparable tools in a real-time simulation environment
• Strong command of communication protocols: CAN/CAN-FD, RS- 422/485, Ethernet/TCP-IP, or similar
• Holistic understanding of automotive powertrain systems and their impact on higher-level vehicle capability
• Willingness to travel for onsite customer and supplier support
• Strong problem-solving, cross-functional collaboration, and communication skills, written and verbal
• Experience with high-voltage power electronics, inverters, or EV/energy storage powertrains
• Prior experience testing onsite at a Tier 1 automotive supplier or OEM test facility
• Proficiency in the NI software suite (LabVIEW, VeriStand)
• Strong C/C++ and Python skills
• Familiarity with functional safety standards (e.g., ISO 26262, or comparable industrial/automotive safety frameworks)
• Startup or fast-paced hard tech development experience
