System Test Engineer- MCU

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.
