Responsibilities

ESC Design (Primary Responsibility)

• Design and develop BLDC/PMSM ESC hardware from concept to production
  
• Typical operating range:
  
• Voltage: 6S–12S (24–60 V)
  
• Current: 40A–100A+
  
• Design and validate:
  
• MOSFET-based power stages
  
• Gate driver circuits (bootstrap, dead-time, protection features)
  
• Current sensing (shunt / inline / Hall-based)
  
• Voltage, temperature, and fault protection circuits
  
• Support control interfaces such as PWM, DShot, UART, and CAN (DroneCAN)
  

Firmware Coordination

• Work closely with firmware engineers on AM32-based ESC firmware
  
• Support hardware–firmware integration, tuning, and debugging
  
• Assist in telemetry, fault reporting, and performance optimization

Other Power Electronics Responsibilities

• Design supporting power electronics including:
  
• DC–DC converters (buck / boost / auxiliary rails)
  
• Battery input protection (reverse polarity, surge, TVS, soft-start)
  
• Power distribution and filtering circuits
  
• Perform thermal design, derating analysis, and reliability improvement
  
• Implement EMI/EMC mitigation through circuit design and PCB layout guidance
  

Prototyping, Testing & Validation

• Prototype bring-up and lab debugging
  
• Switching waveform analysis using oscilloscopes and current probes
  
• Thermal testing under load and stress conditions
  
• Root-cause analysis of failures and design iteration
  
• Support production validation and field issue resolutio

Must Documentation & Collaboration

• Prepare schematics, BOMs, design notes, and test reports
  
• Work with PCB layout engineers to ensure high-current layout best practices
  
• Collaborate with mechanical, firmware, and system teams
  

• B.E. / B.Tech / M.Tech in Electronics, Electrical, or Power Electronics
  

• Minimum 5 years of relevant experience in power electronics
  
• Hands-on experience in ESC design is mandatory
  
• Prior experience with UAV, EV, robotics, or motor-drive systems is preferred
  

• Strong fundamentals in power electronics
  
• Practical experience with:
  
• MOSFET selection and loss calculations
  
• Gate driver design and protection strategies
  
• High-current PCB design concepts
  
• Current sensing and fault handling
  
• Schematic design using KiCad or Altium
  
• Proficiency with lab equipment (oscilloscopes, electronic loads, thermal tools)
  

• Experience with AM32 firmware (highly preferred)
  
• Familiarity with BLHeli or VESC ecosystems
  
• CAN / UART-based ESC telemetry
  
• EMI/EMC debugging experience
  
• Ability to review or perform PCB layout for power electronics
  

• Strong hands-on engineer with real-world debugging experience
  
• Comfortable working in lab and production environments
  
• Able to take ownership of ESC designs end-to-end
  
• Practical, detail-oriented, and reliability-focused
