Senior Electrical Test / Systems Engineer

san jose, ca • Posted 6 days ago
Onsite Full Time Engineering

Responsibilities

  • We are seeking a Senior Electrical (Test) Systems Engineer to serve as the ultimate authority on system health
  • This isn’t a “follow the manual” role
  • You’ll be operating at the volatile intersection of high-voltage power and sensitive low-voltage instrumentation—a boundary where noise, grounding issues, and transients create real-world consequences
  • We need a battle-tested expert who has seen these systems fail in industry and knows exactly how to build them to last
  • Build and maintain real-time test and control applications on NI cRIO, PXI, and DAQ using LabVIEW, VeriStand, and Python, with strong CAN bus integration and test automation experience
  • Interface with subsystems via CAN bus, EtherCAT, Modbus, TCP/IP, and related industrial communication protocols, from initial bring-up through fault diagnosis in deployed systems
  • Diagnose and resolve electrical faults in medium- to high-power test systems including voltage/current ripple, transient noise, EMI, and grounding failures, with full ownership of root-cause findings and mitigation recommendations
  • Lead grounding architecture reviews and remediation across the lab, with specific focus on how high-voltage ground faults cascade into low-voltage instrumentation systems
  • Set up and operate oscilloscopes, signal conditioning hardware, and bench instrumentation to characterize and isolate electrical anomalies in complex, integrated test environments
  • Own ongoing support of delivered test systems including software updates, bug fixes, new feature integration, and in-field troubleshooting to ensure systems remain reliable as configurations evolve
  • Support system bring-up, integration verification, and validation across hardware, controls, and software layers

Qualifications

  • Electrical background with hands‑on grounding architecture, oscilloscope‑based fault diagnosis, and signal conditioning in mixed high/low voltage environments
  • Hands‑on experience with CAN bus, EtherCAT, Modbus, and TCP/IP in deployed, real‑world systems
  • Degree in Electrical Engineering or equivalent hands‑on industry experience
  • Experience with version control (Git) and structured software development practices
  • Proven LabVIEW development on cRIO and PXI platforms — building and maintaining real‑time applications, not just configuring existing ones
  • Python proficiency for test automation, data analysis, and tooling
  • Experience in aerospace, EV powertrain, motor drive, or power electronics test environments
  • HIL or real‑time validation experience (NI, dSPACE, Speedgoat, or equivalent)
  • NI Certified LabVIEW Developer (CLD) or Architect (CLA)
  • Electrical CAD tools (EPLAN, AutoCAD Electrical)
  • Familiarity with NI SystemLink, DIAdem, or TestStand
  • Additional protocols: EtherNet/IP, LIN, RS-232/485
