1. Customer Technical Support & Design-In

• Lead technical ownership for customer design-in activities in power conversion and motor control applications.
• Support customers through the full lifecycle: architecture definition design validation optimization production.
• Provide troubleshooting, debugging, and optimization support on hardware, firmware, and control loops.
• Conduct design reviews to ensure robustness, efficiency, and thermal compliance.

2. Power Conversion Expertise

• Guide customers on power topologies such as:
  • ACDC, DCDC, on-board chargers, DCDC converters
  • Inverters, SMPS, PFC, DAB, LL resonant topologies
• Support system modeling, efficiency tuning, EMI/EMC compliance, thermal optimization, and protection schemes.
• Recommend appropriate power devices (MOSFETs, IGBTs, SiC/GaN) and gatedriver strategies.

3. Motor Control Expertise

• Support motor control for BLDC, PMSM, induction motors and SRM use cases.
• Configure and tune FOC (Field-Oriented Control), sensorless control, and advanced control loops.
• Work with MCU/MPU/NPU-based motor control platforms for EV traction, robotics, whitegoods, industrial drives, HVAC, and mobility solutions.

4. Technical Documentation & Collateral Development

• Develop application notes, schematics, design guidelines, reference designs, and customer kits.
• Create training material and deliver workshops to customers, channel partners, and internal teams.
• Provide technical insights to improve documentation and support materials.

5. Collaboration with Global Engineering Teams

• Act as the technical bridge between India customers and global R&D / product teams.
• Provide field feedback for product roadmap, feature improvements, and bug resolution.
• Support evaluation platform creation, firmware releases, and silicon validation.

6. PreSales & PostSales Technical Enablement

• Partner with Business Development and Sales teams to influence early architecture decisions.
• Present product advantages, benchmarks, competitive comparisons, and solution differentiation.
• Support PoCs, prototypes, and performance evaluations at customer sites.
