Skilled in functional safety standards (ISO 26262), fault management in BMS firmware development, and compliance standards (IEC 62133, UL 1642). Familiarity with BMS hardware platforms and tools such as TI BQ Studio, MATLAB, and Simulink. Ability to develop bootloaders, memory management, and scalable modular software components. Programming proficiency: Embedded C, Python, Ruby, Make. Collaboration & Leadership: Experienced in working with cross-functional teams spanning software, hardware, quality, and mechanical engineering globally. Strong communication skills to articulate technical insights to a wide range of stakeholders, including teams, suppliers, and senior management. Desirable Skills Experience in connected BMS systems involving BLE/Wi-Fi interfaces for consumer products. Experience in working with RISC-V microcontrollers. Knowledge of agile development cycles and test automation frameworks. Expertise in implementing machine learning algorithms for predictive diagnostics in battery systems. At Dyson we are encouraged to think differently, challenge convention and be unafraid to make mistakes. We’re creative, collaborative, practical and enthusiastic, but most of all we’re hugely passionate about what we do. We are looking for individuals who wish to invent, design and develop leading products for the global market. By working in our world class Research Design and Development department, these individuals have the opportunity to work alongside other leading technical specialists and highly motivated creative people, to develop products which fulfill our ambition of being truly different and better than our competitors. Dyson monitors the market to ensure competitive salaries and pension contributions. Beyond that, you’ll also enjoy a profit-related bonus, generous leave and life insurance. However, financial benefits are only the start of a Dyson career. Rapid professional growth, leadership development and new opportunities abound. Dyson is an equal opportunity employer. We know that great minds don’t think alike, and it takes all kinds of minds to make our technology so unique. We welcome applications from all backgrounds and employment decisions are made without regard to race, colour, religion, national or ethnic origin, sex, sexual orientation, gender identity or expression, age, disability, protected veteran status or other any other dimension of diversity. At Dyson we are focused on solving the problems that others have ignored; solving them first using our technology and ingenuity. In order to achieve this we need to pioneer technologies that are different and authentic. This is the core of what we do and who we are. We must strive to create the future, every single day by developing new things, different things, things that go against the grain with a diverse and global team of ingenious minds. Dyson employs 14,000 people and is present in more than 80 countries. And while we are growing fast we want Dyson to remain a start-up in spirit with the freedom of experimentation and learning, constantly reinventing our products as well as reinventing how we work, how we sell and how we support our owners. At the same time we are working through the James Dyson Foundation, James Dyson Award and Dyson Institute to inspire future engineers and pioneering a new approach to engineering education. Underlining everything we do in this diverse environment is the need to always show respect, supporting each other as one team to overcome whatever challenges we encounter. We drive empowerment, development and equality in an inclusive environment for our people around the world. The future doesn’t just happen, we look to make it happen, to achieve leaps through pioneering new ideas.
