About Zeno

An unprecedented energy transition has begun. To meet 2040 net zero goals, over 2 billion electric two-wheelers (motorcycles) must be sold and $11 trillion in fuel consumption replaced. Zeno is building a tech platform to electrify this two-wheeler market, currently responsible for more than 4% of the world’s GHG emissions. Our mission is to accelerate the energy transition and democratize the benefits across Africa, India, and Latin America. With a focus on East Africa as a starting point, Zeno is building a new energy ecosystem with ground-up development of a fundamentally better electric motorcycle and associated battery swap network to drive a better experience for our customers.


The Role

Zeno is seeking a Firmware Engineer (4–7 years) specializing in Battery Management Systems (BMS) to design, develop, and optimize embedded firmware for high-performance battery packs. This role is critical in ensuring the safety, reliability, and efficiency of our energy storage systems powering the next generation of electric two-wheelers.


What You’ll Do

  • Firmware Development: Design, code, and validate embedded firmware for Battery Management Systems (BMS).
  • Safety & Reliability: Implement algorithms for cell balancing, SoC (State of Charge), SoH (State of Health), fault detection, and thermal management.
  • Hardware Integration: Work closely with hardware and systems engineers to integrate firmware with BMS hardware.
  • Testing & Validation: Develop test cases, perform HIL/SIL validation, and ensure compliance with safety standards (ISO 26262, IEC).
  • Optimization: Improve firmware performance for efficiency, reliability, and real-time response.
  • Documentation: Maintain clear technical documentation of design, code, and validation processes.
  • Cross-Functional Collaboration: Partner with product, systems, and manufacturing teams to deliver production-ready BMS solutions.


What You Bring

  • 4–7 years of experience in embedded firmware development for automotive or energy storage applications.
  • Strong expertise in C/C++ programming for microcontrollers (ARM, STM32, TI, NXP, or similar).
  • Hands-on experience with BMS algorithms (cell balancing, SoC, SoH, fault management).
  • Knowledge of CAN, SPI, I2C, UART communication protocols.
  • Experience with RTOS (FreeRTOS, Zephyr, or similar) for real-time applications.
  • Familiarity with ISO 26262 functional safety standards and best practices.
  • Debugging skills using oscilloscopes, logic analyzers, and embedded tools (JTAG, Lauterbach, etc.).
  • Exposure to model-based development (MATLAB/Simulink) is a plus.
  • Knowledge of battery chemistry (Li-ion, LFP, NMC) and EV powertrain systems preferred.
  • Strong problem-solving, debugging, and independent execution skills.
  • Based in Bengaluru, with willingness to work from office full-time (5 days a week).


Benefits

  • Competitive salary based on experience.
  • Company-sponsored healthcare plan.
  • Opportunity to design cutting-edge BMS firmware driving the EV transition.
  • Join a world-class team of engineers, operators, and entrepreneurs building the trillion-dollar transition of two-wheelers to electric.
