Job description

Lyten is leading an industrial revolution through Lyten 3D Graphene™, a breakthrough supermaterial unlocking a new generation of products — from lithium‑sulfur batteries and energy storage systems to concrete admixtures, lightweight composites, and next‑generation sensors that are revolutionizing industries. Together, these innovations are making a massive global improvement and driving real‑world impact across energy, mobility, construction, and defense.

At Lyten, we believe the most meaningful careers begin with purpose — and with people who want to make a difference. We’re not just developing advanced supermaterials — we’re about to change the world as we know it, reshaping how energy is stored, how products are built, and how progress is made.

We’re entering an exciting growth phase, scaling production across the U.S. and Europe and expanding our team of engineers, scientists, and innovators.

Apply now to join our team and be part of something bigger than yourself — where collaboration, creativity, and purpose come together to build the technologies that will define the next century.

Lyten Sweden is seeking a professional Senior Battery Simulation Engineer to join our R&D organisation in Västerås. The Senior Battery Simulation & Modelling Engineer will develop and validate advanced simulation models for battery cells, including performance, degradation, thermal, swelling, and mechanical behaviour. The role supports current NMC products, future battery chemistries, and customer‑facing simulation solutions.

Key Responsibilities

• Battery Model Development Develop and maintain simulation models for battery cells, supporting current chemistry products and next‑generation chemistries.
• Performance Modeling Develop and validate performance models, including ECM‑based approaches, to predict battery behaviour and support BMS applications.
• Lifetime & Degradation Modeling Develop and calibrate lifetime prediction models to accurately estimate battery ageing, performance degradation, and end‑of‑life behaviour.
• Thermal Modeling Develop 3D thermal simulation models to predict temperature distribution and support thermal management optimisation.
• Swelling & Mechanical Modeling Develop swelling and mechanical models to predict cell expansion, deformation, and structural behaviour throughout battery life.
• Safety & Venting Simulation Develop simulation models for vent deformation and pressure‑related mechanical behaviour to support battery safety assessments.
• Validation & Model Correlation Parameterise, validate, and continuously improve simulation models using experimental and product validation data.
• Customer Model Delivery Deliver validated simulation models to customers and provide technical support for performance, lifetime, thermal, and mechanical analyses.
• Cross‑Functional Collaboration Work closely with cell design, materials, testing, and customer teams to support battery development and commercialization programmes.

Qualifications and Experience

• Bachelor or higher in Electrochemistry, Chemistry, Materials, Mechanical or a related discipline; 8+ years of experience in lithium‑ion battery development and modelling.
• Strong industrial experience supporting automotive, ESS, or other advanced battery programmes.
• Proven experience developing simulation models for rechargeable battery systems.
• Experience working directly with OEM customers and customer‑facing engineering projects.
• Experience with prismatic cell development is highly preferred.
• Strong expertise in electrochemical, thermal, degradation, swelling, and mechanical battery modelling.
• Proficiency in MATLAB/Simulink, Python, COMSOL Multiphysics, LS‑DYNA, and ANSYS simulation tools.
• Experience in model parameterisation, validation, optimisation, and correlation with experimental data.
• Knowledge of multi‑physics simulation and battery safety analysis is highly desirable.
• Strong technical leadership, problem‑solving, and analytical skills.
• Ability to work independently and drive complex projects in a dynamic environment.
• Excellent communication and collaboration skills across teams and customers.
• Results‑driven mindset with a focus on engineering quality and delivery.

Preferred Experience

• Experience with prismatic lithium‑ion batteries and advanced chemistries (NMC, NMX, Li‑S).
• Knowledge of battery safety, thermal, mechanical, and venting behaviour.
• Experience in multi‑physics simulation, digital twin, or cell‑to‑pack modelling.
• Experience delivering simulation models for customer applications or BMS development.
