Production Engineer - Motor

Business Unit: EPS Mobility

Role: Production Engineer – Traction Motor

The Product Engineer – Traction Motor is responsible for supporting the end-to-end product development, industrialization, validation, and lifecycle management of EV traction motors. The role will work closely with product management, design, manufacturing, quality, suppliers, and customers to translate market and customer requirements into technically feasible, competitive, reliable, and manufacturable traction motor products.

The role covers the complete traction motor architecture including stator, rotor, housing, shaft, bearings, cooling systems, insulation systems, winding technologies, and motor assembly. The Product Engineer will support product definition from concept through design, prototype development, validation, production launch, and continuous product improvement.

You will play a key role in ensuring that traction motor products meet performance, efficiency, cost, reliability, manufacturability, safety, and customer requirements, while supporting the organization’s product roadmap and electrification strategy.

• Support the definition and development of motor architecture including stator, rotor, shaft, housing, bearings, cooling systems, insulation, and winding technologies.
• Work closely with motor design engineers to optimize motor performance, efficiency, torque-speed characteristics, NVH, thermal performance, and reliability.
• Support design trade-off studies considering performance, cost, manufacturability, weight, packaging, and scalability.
• Participate in design reviews and ensure product requirements are properly cascaded across mechanical, electrical, thermal, and manufacturing domains.
• Benchmark competing traction motor technologies, architectures, materials, and manufacturing approaches.

Product Requirements & System Engineering

• Develop and maintain Product Requirement Documents (PRD), technical specifications, and product feature definitions.
• Define key product performance parameters including power, torque, speed, efficiency, voltage, current, thermal limits, cooling requirements, and NVH targets.
• Support requirement management and traceability throughout the product development lifecycle.
• Coordinate with vehicle OEMs and internal stakeholders to understand application-specific requirements and duty cycles.
• Support system-level integration of the traction motor with inverter, transmission, battery, vehicle control systems, and thermal management systems.
• Identify critical-to-quality (CTQ) and critical-to-performance (CTP) parameters for traction motor products.

Traction Motor Technology & Design Support

• Develop technical understanding of various traction motor technologies including PMSM, IPM, SPM, induction motors, and emerging motor architectures.
• Support engineering activities related to stator laminations, winding systems, hairpin technology, conventional winding, insulation systems, rotor assemblies, magnets, and cooling systems.
• Evaluate different material and technology options including electrical steel, permanent magnets, copper conductors, insulation materials, adhesives, and thermal interface materials.
• Support electromagnetic, thermal, mechanical, and NVH optimization activities in collaboration with simulation and design teams.
• Participate in technology scouting and evaluation of next-generation motor technologies.

Validation, Testing & Performance Evaluation

• Support development of Design Verification (DV) and Product Validation (PV) plans for traction motors.
• Coordinate and monitor motor testing including performance mapping, efficiency, thermal performance, durability, vibration, NVH, dielectric strength, insulation resistance, and environmental testing.
• Analyze test results and identify deviations from product requirements.
• Support root cause analysis and corrective actions for validation failures.
• Work with test laboratories and external partners for specialized validation activities.
• Ensure test specifications, procedures, and acceptance criteria meet customer and industry requirements.
• Support End-of-Line (EOL) test strategy and performance parameter definition.

Cross-Functional Program Management

• Act as a technical interface between product management, engineering, manufacturing, quality, purchasing, suppliers, and customers.
• Support program planning, milestone tracking, risk management, and issue resolution.
• Track engineering deliverables and ensure alignment with project timelines.
• Participate in customer technical discussions and support clarification of product requirements.
• Coordinate cross-functional teams during prototype builds, validation, pilot production, and production launch.
• Escalate technical risks and support mitigation planning.

Problem Solving & Continuous Improvement

• Support structured problem-solving activities using 8D, 5-Why, Fishbone, and A3 methodologies.
• Investigate product performance issues during development, validation, manufacturing, and field operation.
• Drive continuous product improvements based on test data, manufacturing feedback, customer feedback, and field learnings.
• Support lessons-learned documentation and ensure knowledge is incorporated into future product development programs.
• Identify opportunities for product standardization and modular platform development.

Product Lifecycle Management

• Support product lifecycle management from concept development through production and end-of-life.
• Maintain product documentation including specifications, BOMs, drawings, validation reports, and engineering change records.
• Support Engineering Change Requests (ECR) and Engineering Change Orders (ECO).
• Monitor product performance and field feedback after SOP.
• Support product upgrades, cost optimization, reliability improvements, and technology refresh initiatives.
• Contribute to long-term traction motor product and technology roadmaps.
