Bengaluru, India Zeno Full time

FIRMWARE ENGINEER - BMS Location: Bengaluru – Work from Office (5 days a week) Start Date: Immediate 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.
