Junior Academic Employee in Modelling Thermal Energy Storage Systems - DTU Energy

Join DTU Energy as a Junior Academic Employee and work on modelling and simulating thermal energy storage systems in cutting-edge research projects.

Our research focuses on modelling, simulation and analysis of thermal energy storage systems and their role in flexible and efficient energy systems. Thermal energy storage is a key enabling technology for integrating renewable energy and supporting industrial energy applications.

The position is embedded in DTU Energy’s research activities on thermal energy storage, carried out in close collaboration with international research partners and within externally funded research projects.

The job
As Junior Academic Employee, you will support research activities within thermal energy storage and energy system modelling at DTU Energy. The position is anchored in ongoing research projects and focuses on simulation-based analysis of thermal energy storage systems and their interaction with other energy and process units.

You will be part of a research group working on system-level modelling and will collaborate closely with researchers and PhD students. The position offers the opportunity to gain hands-on experience with applied modelling tasks and to develop technical skills within energy systems analysis.

Primary areas of responsibility include:

• Supporting the development and maintenance of simulation models for thermal energy storage systems
• Implementing and testing heat and mass balance models at system level
• Assisting with the integration of thermal energy storage models with other energy conversion or process units
• Supporting analysis of system performance under different operating and load scenarios
• Contributing to documentation, figures and technical material for internal reports and publications.

Background in energy systems modelling and thermal energy storage
We expect you to have a background in engineering or energy-related disciplines and an interest in modelling and simulation of energy systems, in particular thermal energy storage. You hold a BSc degree in a relevant field and are interested in applying your technical knowledge to practical modelling tasks in a research environment.

Relevant qualifications include:

• Bachelor’s degree in energy engineering, mechanical engineering, chemical engineering or a related field
• Basic knowledge of heat transfer, thermodynamics and energy systems
• Interest in numerical modelling and simulation of engineering systems

Technical skills:

• Experience with MATLAB, Python or similar numerical tools
• Experience with modelling, simulation or data analysis
• Familiarity with system-level modelling is an advantage, but not a requirement

Personal qualities we value include:

• Ability to work independently and as part of a team
• Structured working approach and attention to detail
• Good communication skills in English
• Motivation to learn and contribute to ongoing research activities

What we offer in return
We offer an interesting and challenging position in an international research environment with a strong focus on energy systems modelling and thermal energy storage. You will become part of a professional and collaborative research group working on externally funded projects in close interaction with researchers and PhD students. At DTU Energy, we emphasize a high level of professionalism, and skills development is an integral part of our daily work. 

The position offers flexible working hours that can be adjusted to your studies or other commitments

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations (AC).

The position is a part-time position with working hours corresponding to approximately 15 hours per week. The exact number of hours can be adjusted based on mutual agreement. 

The starting date is 1 April 2026 or according to mutual agreement. The period of employment is 1,5 years. The workplace is DTU Lyngby Campus.

Application and contact
Please submit your online application no later than 1 March 2026. Open the “Apply now” link, fill out the form and attach your motivated application, CV and exam certificates. 

Further information may be obtained from Professor Ming Chen (minc@dtu.dk). Please do not send applications to this e-mail address, instead apply online as described below.
