Senior Firmware Engineer

Designation:

What Were Building

Clean Electric

Were a fast-scaling hardware-tech company, and our products are in motionliterally. They power EVs, charge urban transport, and help decarbonize cities across India. Behind all this? Robust firmware that keeps our systems safe, stable, and smart. That’s where you come in.

Why This Role Matters

Senior Firmware Engineer

This is a critical technical leadership role for engineers who want to design high-impact firmware in a high-performance environment.

What You’ll Do

• Own BMS firmware development — Plan, design, and implement firmware features for next-gen battery systems.
  
• Collaborate cross-functionally — Work with hardware engineers to define system interfaces, power architecture, and communication protocols.
  
• Develop core functionalities — Write firmware for state estimation, cell balancing, thermal management, and system diagnostics.
  
• Ensure system safety — Implement algorithms to monitor and protect against over-voltage, over-current, over-temperature, and SoC mismanagement.
  
• Integrate across systems — Work with communication protocols like SPI, I2C, UART, and CAN to ensure seamless system interaction.
  
• Maintain high standards — Perform code reviews, unit testing, and system validation for robust and production-grade releases.
  
• Debug and troubleshoot — Use tools like oscilloscopes, logic analyzers, and in-circuit debuggers to identify and fix firmware issues in live systems.
  

You Might Be a Fit If You

• Have

  3+ years

  of experience in

  embedded firmware development

  (preferably in energy storage, EVs, or automotive applications).
• Are fluent in

  C/C++

  , with strong fundamentals in real-time embedded programming.
• Have deep experience with

  communication protocols

  : I2C, SPI, UART, CAN.
• Have worked with

  microcontrollers

  such as

  ARM, ESP32, or RENESAS

  families.
• Have hands-on exposure to

  hardware components

  like ADCs, CAN transceivers, LTE modules, or GPS units.
• Are excellent at debugging and system bring-up using hardware tools.
  
• Are a strong communicator who thrives in collaborative, cross-functional teams.
  

Bonus Points If You

• Have prior experience working on BMS or battery-related firmware.
  
• Have contributed to safety-critical or automotive-grade firmware.
  
• Are comfortable working in early-stage environments with fast iteration cycles.
  
• Have worked with OTA updates or secure boot mechanisms.
  

What’s In It for You

• Flexible working hours

  — We care about impact, not office clocks.

• ESOPs

  — Be part of the journey and grow with us.

• Real impact

  — Build systems that run on real roads and power real EVs across India.

• Growth runway

  — Scale your role into system architecture, team leadership, or product ownership.

• Work with hardware and leadership

  — You’ll be at the core of tech and strategy conversations
