System Test Engineer- MCU
About this role
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.
