hela Sverige At Koenigsegg, innovation drives everything we do. As part of our Powertrain department, you'll work alongside passionate engineers developing world-leading technology for the next generation of high-performance vehicles.
We are currently looking for a Battery Algorithms Software Engineer to join our High Voltage and Battery team, where you will develop advanced algorithms and software for Koenigsegg's next generation of high-voltage battery systems.
In this role, you will contribute to the development of advanced battery software for high-voltage systems, working with modelling, simulation, and software development. You will collaborate closely with cross-functional engineering teams throughout the development process, from concept and testing to software integration and continuous improvement.
Responsibilities:
You will be responsible for developing and validating battery algorithms and embedded software for high-voltage battery systems, supporting the full development cycle from battery modelling and algorithm development to software integration, testing, diagnostics, and vehicle-level validation.
You will:
Develop battery models and estimation methods based on cell and pack test data.
Develop and maintain algorithms for State of Charge (SoC), State of Health (SoH), State of Power (SoP), energy availability, and battery diagnostics.
Translate mathematical models and prototype algorithms into production-quality embedded C code.
Optimize algorithms for execution time, memory usage, numerical stability, and embedded hardware constraints.
Define software requirements, interfaces, diagnostics, acceptance criteria, and verification methods.
Develop test plans, set up test environments, and perform software and algorithm testing.
Analyze estimation errors and unexpected battery behaviour, and implement improvements to enhance algorithm performance and robustness.
Support BMS software integration, testing, release, and continuous improvement.
Develop and support OBD diagnostic functionality for battery systems.
Requirements:
Bachelor's or Master's degree in Computer Science, Electrical Engineering, Control Engineering, or a related field.
Experience in battery modelling and SoX algorithm development.
Strong programming skills in C, preferably with experience in embedded or real-time systems.
Good understanding of lithium-ion battery behaviour, including OCV, internal resistance, temperature dependence, ageing, and power capability.
Ability to analyse large test datasets and translate physical battery behaviour into robust algorithms.
Experience with software testing, debugging, version control, and structured software development practices.
A systematic and analytical approach to problem-solving.
Ability to communicate complex technical concepts clearly and collaborate effectively across multiple engineering disciplines.
Experience with MATLAB/Simulink modelling and simulation.
Strong communication skills in English.
Meritorious experience:
Previous experience with automotive battery management systems (BMS) or electrified powertrains.
Experience using MATLAB and Simulink for modelling, algorithm development, data analysis, or model-based design.
Knowledge of estimation techniques such as Kalman filtering, observers, parameter identification, and adaptive algorithms.
Applications are reviewed on an ongoing basis, so don't wait to apply. We look forward to receiving your application!
Koenigsegg is most known for building some of the fastest cars in the world; with almost all of our megacar technologies that are patented and made in-house by our almost 750 world-class technicians, engineers, sourcing experts, production craftsmen, and communicators.
What we've created is a unique proving ground of engineering creativity that makes use of our breakthrough megacar development and legacy to push the boundaries of sustainable mobility technology.
So, what's next?
We are on a universe-denting mission to develop the next generation of breakthrough tech and products. We are looking for outstanding, impactful, and authentic individuals to grow with us. Our ambitions are inspiring but will push the limits of what is possible – requiring one to work efficiently amid our cross-functional teams to execute at high-quality levels.
The goal is clear: innovate and transform.
