About us

We are a technology powerhouse that designs, engineers, and manufactures the world's most advanced automotive technology and hypercars. Bytes to bolts, Rimac is where everything happens.

Our teams develop and produce both hardware and software solutions for our flagship, record-breaking hypercar, the Nevera, as well as for other automotive manufacturers’ vehicles. Working on technology solutions for partners such as Porsche, Hyundai, Aston Martin, Koenigsegg, Automobili Pininfarina, and others, gives Rimac a unique position of a technology leader in the high-performance electric vehicle industry. The stakes are high.

As a fast-moving company, we nurture a high-performing culture. If you are interested in joining, you must be prepared for relentless learning, adapting, and embracing new technologies. We expect an easy-going person, but also self-driven, entrepreneurial, and highly independent in their work, that will enjoy rising to the challenge and have fun pushing the limits of technology.

Our expectations are high. And we can only achieve our goals with the dedication and collaboration of our exceptional team. Our ambition is to deliver and go the extra mile. We need to expand our already industry-leading team, find the best people, and lead the charge.


The Advanced Battery Software team at Rimac Technology is developing a cloud-based battery management system to monitor, predict, and suggest operating changes to ensure optimum battery performance is achieved through to the point of recycling. This enables a transparent view of battery health, which is critical to extracting the maximum value from the system. Extending the life of a battery system also spreads the embedded emissions from manufacture across a longer use period, offering environmental benefits.

We are looking for a Cell Modeller to develop a robust and accurate cell model that underpins this activity. This will require a combination of equivalent circuit models, physics-based models, “big-data”, and machine learning techniques. There is the opportunity to collaborate with other teams within Rimac Technology as well as academia.

It is an exciting time to join the foundation of a team that is developing solutions across multiple mobility and energy applications.

  1. Responsibilities

There is some flexibility in the role, so please apply even if can only achieve a subset of these activities:

  • Develop cell models that capture individual electrode dynamics:
    • Equivalent circuit models: electro-thermal and physics-informed.
    • Physics-based models: DFN and ROM.
  • Develop degradation tracking algorithms to adapt cell model.
  • Work across teams to develop experimental techniques for robust model validation.
  • Evaluate available cloud data and define data acquisition requirements for cloud-based model.
  • Develop a modelling framework in Matlab and Python using test-driven approaches and version control.
  • Support teams across the company with model development.



  1. Requirements
  • Masters or PhD in Electrochemistry, Chemistry, Mechanical engineering or similar.
  • Experience working with lithium -ion cells in industry is desirable but not essential.
  • Be a self-starter comfortable with finding and focussing on the critical path to deliver quickly.
  • Experience with MATLAB and Simulink.
  • Experience with programming languages such as Python and C/C++.
  • Experienced with cell modelling tools such as Pybamm, COMSOL or similar.
  • Experience with test-driven code development.
  • Strong analytical and problem-solving skills.
  • Experience developing cell test plans.
  • Hands-on experience of lithium-ion cell and module testing and associated equipment.
  • Proficient in Microsoft Office (Outlook, Teams, Word, Excel, PowerPoint, Project).
  • Ability to prepare and present effectively to audiences from different professional backgrounds.
  • Bring a positive attitude and enthusiasm to the team.
  • Willing to travel domestically and internationally, as required.


3.  Considered as an advantage

  • Experience with machine learning techniques.
  • Experience working with cloud data services.
  • Experience using APIs and querying databases.
  • Experience with Linux and version control tools such as Git.
  • Experience in using software data management and distributed version controls systems (e.g., Github, Gitlab, Bitbucket, etc.) is preferred.
  • Experience implementing embedded code into battery management systems.
  • Experience working in or leading cross-functional teams.



4.What we are like and what we offer

  • We operate in a fast-paced and challenging environment
  • You will have the opportunity to work on world-class solutions with cutting-edge technology
  • We work a lot, but also know how to have fun (fun teambuilding, crazy company parties, kitchen and relaxation zones around the office, free coffee/tea and fresh fruit, etc.)
  • Family-like and open work environment (subsidies for kindergartens, Christmas parties for kids, and presents for kids)
  • Financial subsidy for transportation
  • Additional and supplementary healthcare covered
  • Internal educations program
  • Psychological counseling
  • Dog-friendly office
  • Flexible working hours and work-from-home days – up to 12 days of remote work per month
  • Discounts at stores and clinics – for humans and pets 😊

If you are a creative, problem solving, open-minded, highly-motivated individual and you love a fast-paced environment and are up for the challenge – where were you hiding?
