Description du poste

Siemens Digital Industries Software (SW) helps organizations of all sizes digitally transform using software, hardware and services from the Siemens Xcelerator business platform. Siemens' software and the comprehensive digital twin enable companies to optimize their design, engineering and manufacturing processes to turn today's ideas into the sustainable products of the future. From chips to entire systems, from product to process, across all industries, we accelerate transformation. Siemens Digital Industries Software is one of five business units of Siemens Digital Industries (DI), a leading innovator in automation and digitalization. The other four businesses are Factory Automation, Process Automation, Motion Control and Customer Services.
Start your career with the Strategic Student Program (SSP)
The Strategic Student Program is our formal internship program globally. You will be mentored by guides and again invaluable professional experience. At Siemens, SSP interns get access to an international student network and community, career development opportunities with professional growth pathways, comprehensive practical training throughout the program, access to the Siemens Learning Hub and other training materials, and the opportunity to collaborate on exciting projects within a global, diverse team.
Internship topic: Advanced modeling and testing of lithium-ion battery cells.
What you'll be doing
In collaboration with the Physics team of Simcenter Amesim and the research institute IFPEN, you will contribute to a joint industrial-research project focused on the modeling and experimental characterization of lithium-ion battery cells. These cells are at the heart of electric vehicles and energy storage systems, and accurate modeling is vital for building reliable digital twins that support design, control, and safety strategies.
Your work will involve both experimental and theoretical aspects, including:
  • Participating in test campaigns on lithium-ion cells under various operating conditions
  • Analyzing electrical and thermal behavior based on experimental data
  • Supporting the calibration and validation of battery models used in digital twin applications
  • Exploring modeling strategies to improve the representation of key physical phenomena
  • Collaborating closely with both industrial and academic mentors throughout the internship
The objective is to validate existing modeling and testing methods on state-of-the-art battery cells and work with your tutors to identify potential areas for improvement.
This 6-month internship is based in Lyon (69), France and is available from January 2026.
