Job Description:

Responsibilities:

• Own and execute firmware design activities for power electronic converters, working closely with hardware, controls, and system teams.
• Architect, develop, and optimize embedded firmware in C/C++ for power electronic converters.
• Design and implement drivers and application layers using peripherals such as ADC, PWM, GPIO, CAN/CAN-FD, I2C, SPI, EEPROM, and timers.
• Define firmware state machines, implement closed-loop control algorithms, and design fault handling, protection logic, and communication protocols.
• Lead hardware–firmware integration, bring-up, and validation of power converter platforms.
• Perform root cause analysis of firmware–hardware interaction and closed-loop control issues and drive corrective actions in coordination with control and power teams.
• Own planning and execution of firmware testing on prototypes, including functional, stress, and corner-case testing.
• Develop test cases, test plans, and validation procedures for embedded firmware and systems.
• Contribute to coding standards, best practices, and review processes.
• Review firmware designs and code of junior engineers.
• Provide technical guidance and mentorship to team members.
• Prepare firmware design documents, interface specifications, and release notes.

Desired Qualifications and Skills:

• Master’s in Power Electronics or B.E. in Electrical Engineering with 5 to10 years of relevant industry experience.
• Strong understanding of closed-loop control of power converters and hands-on experience implementing digital control algorithms on embedded platforms.
• Experience in safety and reliability coding standard and practices.
• Conversant with bootloaders and firmware update mechanisms.
• Hands-on experience with debug tools (logic analyzers etc)
• Experience with TI C2000 family microcontrollers is a plus.

What can you expect:

• Work on high-power, grid-connected and renewable energy systems with real-world deployment.

• Opportunity to influence firmware architecture, control strategies, and system-level design decisions.

• Exposure to the full product lifecycle from concept to production.

• A collaborative environment with strong interaction between firmware, power electronics, and control teams.

• Reports Director – Electrical Engineering, with a clear technical growth path toward Staff Engineer / Engineering Manager roles.

If you are a hands-on power electronics firmware engineer who enjoys system-level ownership and working closely with power electronics hardware and control teams, this role may be of interest to you.
