Doctoral Researcher, Energy Technology (Automated Combustion Model Calibration)

The University of Vaasa creates an inspiring environment for meaningful work as part of a thriving and diverse university community. Our open-minded, multidisciplinary research responds to the challenges of our time and creates a more responsible future. Our internationally respected education gives students the skills and attitude to change tomorrow. The core of our university is made up of high-level expertise in business sciences, technology and administration and communication sciences. 

Wärtsilä and the University of Vaasa are at the forefront of shaping a smarter and more sustainable future through close collaboration and innovation. Together, they drive ecosystem development by combining cutting-edge research with industrial expertise, fostering new technologies, business models, and talent. This partnership plays a key role in accelerating the green transition and strengthening the region’s position as a hub for clean energy and maritime solutions.

We are now inviting applications for the position of Doctoral Researcher. The position is for a fixed term of 3 years (possible 1 year extension later) with a starting date in January 2026 or earliest possible date mutually agreed between both parties. 

Project description

Wärtsilä and University of Vaasa are advancing the development of next-generation combustion systems through a combination of experimental testing and state-of-the-art simulation methods. Simulation tools such as predictive 0D/1D engine models are essential for resolving the calibration complexity problem of novel combustion concepts.

The challenge lies in continuously improving the accuracy, predictiveness, and applicability of such models while ensuring they can be effectively integrated into the engine development process. This includes aspects such as automatic model calibration, validation, while efficiently using the testing time.

We invite candidates to propose how they would approach this challenge— through new methodologies deeply integrating simulations and experiments. The role offers the opportunity to contribute to Wärtsilä’s future technology development while shaping the way advanced simulation tools support worldwide energy/powertrain research.

Position placement and mentoring

The research project is part of Wärtsilä-University CoDoc funding model. CoDoc is a unique doctoral partnership where companies and the University of Vaasa join forces to tackle real-world challenges. Through co-funded dissertations, partners gain cutting-edge research, innovation support, and dedicated collaboration that drives impact. 

You will be employed by the University, but your work time will be divided between the University Campus and Wärtsilä Vaasa STH laboratory, to provide best-possible methodological support for your doctoral dissertation project. Correspondingly, if you are selected for the position, you will then also need to enroll in the University of Vaasa Doctoral Programme according to the normal admission process (rolling admission). It means that you must fulfill the eligibility and admission criteria of the Doctoral Programme. 

Within the University you will be part of an internationally renowned Efficient Powertrain Solution (EPS) Research team working at the forefront of research and development of novel combustion engine technologies. With over 40 researchers and 3MEu of annual Research turnover, we are the biggest focused powertrain-oriented research group in Finland. Our focus is on model-based development of advanced engine solutions supporting our industrial partners in conforming to straightening emissions and noise regulation in marine and off-road sectors. The research Group provides dedicated mentoring and is responsible for implementation of your advanced doctoral courses.

As an industrial PhD you will be working closely with Wärtsilä engines research and development department to maintain the research relevance for industry, addressing real world challenges. Co-supervision will be provided by related subject matter experts at Wärtsilä and your research outcome will be pressure tested in real world applications.

All tasks are agreed in more detail in the Annual Work Plan. The annual working time is 1612 hours.

Required qualifications and experience

• You have a master’s degree in a relevant field related to multidisciplinary energy research. For example, mechanical engineering, with a specialization in combustion engines, Energy Engineering, Control Engineering, etc. 

• You can utilize, develop and integrate different programing and modelling tools. Therefore, extensive familiarity with environments such as C/C++, MATLAB/Simulink, Python is essential. Experience with industry-standard engine simulation software like GT-Power/GT-Suite is considered a benefit.

• In addition to the toolchain experience, you should have experience in control implementation using rapid-prototyping platforms like SpeedGoat or D-Space. Alternatively, background in engine testing and test-bed instrumentation can be considered a good starting point for the position.

• Very good analytical skills in addition to good academic writing skills are highly advantageous for your candidature. Proven track record in relevant projects and high-quality journals/conferences/projects, on the topics related to the position, is an additional advantage. 
• You enjoy developing innovative solutions to technically challenging problems and have the right mix of intellectual curiosity and applied pragmatism. 
• You have good communication skills, and enjoy working both independently and as part of a team. You are open to sharing your knowledge with colleagues and ambitious to develop yourself as a researcher.
• The project is very ambitious and candidates should show excellent project management skills and ability to work under pressure.
• Beyond the above the selected must be eligible to apply and receive the right to study in the University of Vaasa doctoral program before the start of the employment relationship.  More information about applying for doctoral education: Admission to doctoral studies | University of Vaasa.
