Job Description

Business Unit: EPS Mobility

Role: System Tester – MCU (Motor Control Unit)

The System Tester for Motor Control Unit (MCU) is responsible for end-to-end verification and validation of motor control systems across bench, HIL/SIL, inverter test rigs, dyno, and vehicle-level environments. The role ensures the MCU meets requirements for functionality, performance, robustness, diagnostics, reliability, and compliance under real-world operating conditions and corner cases.

Key Responsibilities

  • Create and maintain system test strategy, test plans, and test matrices aligned to product requirements. 
  • Derive test scenarios from system requirements, use cases, and safety/quality goals. 
  • Define test coverage across operating modes (normal, derating, limp-home, fault modes) and environmental conditions.
  • Develop and execute tests for motor control MCU functions, such as: 
    • Start/stop sequences, torque/speed control response, mode transitions
    • Regeneration and braking coordination (where applicable)
    • Thermal derating, voltage/current limitations, and protection behaviors
  • Build and automate tests on HIL rigs (e.g., dSPACE/NI/Vector), and bench setups including inverter + motor + load.
  • Develop automated regression suites for repeated validation: 
  • Test scripting (Python/CAPL/MATLAB/Simulink Test or tool-specific frameworks)
  • CI-friendly execution and reporting (where applicable)
  • Maintain test artifacts: scripts, configuration files, datasets, and baselines.

Qualifications: 

  • Bachelor’s/Master’s in Electrical/Electronics, Embedded Systems, Mechatronics, or related. 
  • 3–8+ years experience in system testing/validation of embedded ECUs (automotive/industrial). 
  • Strong understanding of Motor control systems and inverter basics (PMSM/BLDC/IM fundamentals helpful)
  • ECU testing lifecycle, test design techniques, and defect management
  • Hands-on experience with at least one: 
  • HIL platforms (dSPACE, NI, Vector, etc.)
  • Bench testing with inverter + motor setups and measurement equipment
  • Comfortable with automotive networks & tools: 
  • CAN/LIN/Ethernet, UDS diagnostics, CANoe/CANalyzer (or equivalent)
  • Strong analytical and problem-solving skills.
  • Excellent communication and cross-functional collaboration.
  • Ability to manage multiple integration tasks across vehicle programs.
  • Detail-oriented with a focus on safety, performance, and reliability.
  • Passion for electrification and automotive innovation.
