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
