Role Description

Senior Test Engineer – Electric Motor & Inverter Systems

You will interface with motor and inverter design teams, controls engineers, external labs, and homologation partners to ensure products meet all performance, reliability, and regulatory benchmarks.

This is a high-impact role ideal for an engineer with a strong testing mindset, hands-on experience with electric powertrain systems, and a drive to build quality products at scale.

Responsibilities

• Plan and execute validation of electric motors and inverters, covering performance, thermal behavior, efficiency, durability, and fault handling
• Responsible for homologation and support certification tests for motors and inverters
• Work with external labs and certification agencies for outsourced testing, type approval, and compliance reporting
• Design and lead long-term lifecycle and endurance tests for motors and inverters under representative operating conditions
• Set up and operate dynamometers and other test benches with instrumentation for torque, speed, temperature, vibration, and electrical signals
• Validate inverter performance for mechanical, electrical and environmentals test.
• Extract and analyze signals using CAN tools, interpret DBC files, and monitor control communication
• Process large datasets using MATLAB, Python, or Excel to identify trends, performance limits, and degradation
• Lead the development and operation of dedicated gear durability test rig

  s

  to evaluate wear, efficiency, and NVH performance over lifecycle conditions.
• Drive automation of testing routines, data logging, and report generation
• Maintain test bench assets, manage calibration schedules, and ensure test readiness
• Mentor junior engineers and technicians in safe and effective testing practices

Qualifications

• Master’s/M.Tech or B.E./B.Tech in Mechanical, Electronics, Electrical, Mechatronics, or similar discipline.
• 4+ years of hands-on experience in testing of electric motors, inverters, or power electronics systems. Experience in Automotive field is preferred.
• Strong knowledge or involved in R&D of electric motor and inverter.
• Proven track record of driving products from concept stage through design validation, testing, homologation, and successful production launch.
• Past exposure to test standards and homologation testing or direct coordination with government-approved test agencies is a strong plus.

Preferred Skills

• Expertise in mechanical testing rigs, sensor integration, and data correlation.
• Advanced proficiency in Matlab and Simulink environment.
• Experience with test equipment: torque sensors, thermocouples, RTDs, current clamps, HV probes.
• Familiar with test standards for ingress protection (IPX5/IPX7), homologation, UL certification etc.
• Knowledge of root cause analysis and FMEA methodologies.
• Strong troubleshooting ability in production-critical or field-failure scenarios.
• Excellent communication, planning and collaboration across departments.
• Effective leadership and mentoring skills for junior team members.
