Do you want to explore how emerging digital technologies, intelligent energy systems, or advanced thermal solutions can accelerate the sustainable transformation of buildings and infrastructure? We are looking for doctoral researchers to join us at LUT University and contribute to research on future building energy systems and thermal technologies.

LUT Civil Engineering is a new, growing part of the LUT School of Energy Systems, and now hiring three doctoral researchers with a strong interest in sustainable building energy systems, thermal technologies, and emerging digital infrastructure. The positions focus on developing innovative solutions for energy-efficient buildings and infrastructure through advanced thermal management, intelligent control systems, and computational approaches for sustainable energy systems. We seek enthusiastic researchers motivated to expand their expertise, engage in high-level scientific work, and contribute to societally relevant research.

We are also currently seeking other civil engineering professionals with a range of specialties; see our other job openings here.

What your work will be like

You will contribute to research on one of the following areas:

• Advanced thermal management and heat transfer technologies for energy and infrastructure applications. The position focuses on developing high-performance thermal solutions for energy and infrastructure applications, with a particular emphasis on liquid cooling, microchannel and cold-plate technologies, phase change materials, heat transfer enhancement, and thermal design and optimisation.
• AI infrastructure and building energy systems. The position strengthens research on sustainable building and district energy systems by investigating their interactions with emerging AI infrastructure, with particular emphasis on energy efficiency, energy flexibility, waste heat utilisation, renewable energy integration, and low-carbon energy solutions.
• Occupant-centric building energy systems and smart heating control. The position advances research on energy-efficient and human-centred residential heating by investigating intelligent control of heating systems, with particular emphasis on occupancy sensing and prediction, smart thermostatic radiator valve (TRV) control, occupant interaction, thermal comfort, and energy efficiency.

The positions are based in the newly established LUT Civil Engineering team, and you will work closely with your supervisor and your research group.

As a doctoral researcher, your primary goal is to complete your doctoral degree. You will actively participate in the research group's activities and contribute to research projects in various ways. Depending on the position, your work may involve conducting research, developing computational models, analytical methods, and control solutions, carrying out and analysing field experiments, and analysing and documenting research results. You will disseminate your findings through peer-reviewed scientific publications and presentations at international conferences and research meetings.

In addition, you will contribute to national and international research projects in close collaboration with your research team and external partners. Your role may also include teaching and assisting in teaching at the bachelor’s and master’s levels, supervising student projects where appropriate, and contributing to research group and project activities.

The selected candidates must apply for the right to pursue doctoral studies at the LUT Doctoral School within the first two months of employment.

What we expect

A relevant master’s degree is required. Depending on your chosen research topic, your educational background may relate to energy engineering, building services engineering, mechanical engineering, civil engineering, complex systems, automation and control engineering, computer science, data science, computational science, applied mathematics, thermal engineering, or a related field.

We expect you to have strong interest in your chosen research area and an academic background that supports it. Depending on the topic, experience in scientific programming, computational modelling, CFD, building energy modelling, data-driven methods, optimisation, control, statistical or probabilistic modelling, or related quantitative methods is considered an advantage. The role requires commitment to completing your doctoral studies within their normative timeframe. We value strong academic writing skills and motivation to contribute to high-quality scientific publications during your doctoral studies. Written and spoken fluency in English is required, and other language skills are considered an asset.

Strong analytical and problem-solving skills are essential. You should be able to work independently, communicate findings clearly, and collaborate effectively in an international research environment. Prior scientific publications are not required but are considered an advantage. Previous research experience is beneficial but not required, and motivated early-career candidates are encouraged to apply. Commitment to responsible and ethical research practices is essential.

As the LUT Civil Engineering is just being established, you should be comfortable operating in an evolving environment where uncertainty and change are part of everyday work.

What we offer

We offer a collaborative research environment where you will contribute to societally relevant research, build your academic publication record, and receive close support from your supervisor throughout your doctoral studies.

The employment relationship starts with a one-year term. The contract may be extended by three years if your progress in your studies and research in the first year is satisfactory. The employment begins with a six-month trial period.

The work starts as soon as possible, and the start date is negotiable. The position is based at LUT’s Lahti campus in Finland. LUT offers a hybrid work model that combines flexibility with regular on-campus presence. The hours are flexible and support work–life balance. The position follows a system of 1,612 annual working hours in accordance with the collective agreement for Finnish universities.

The salary is set according to the Finnish university pay system’s scale for teaching and research staff (requirement level 2). The starting salary is approximately EUR 3,100 per month, depending on experience and qualifications.

Interested? Please submit your application by 4 October 2026 at 23:59 (Finnish local time, UTC+3). Fill out the online form and attach the following documents in English and in PDF format:

• A motivation letter (one page) highlighting your research skills relevant to the position and describing why you are interested in and suitable for the position
• A curriculum vitae (CV) following the guidelines of the Finnish Advisory Board on Research Integrity
• Copies of your original bachelor’s and master’s degree certificates and transcripts of records. If the original documents are not in English, Finnish, or Swedish, official certified translations are required
• Contact details of two references

Please also indicate which of the three topics most interests you.

Submit your application well before the deadline to allow time for uploading all attachments. Also, make sure you submit only one application.

Only applications that are submitted through the online recruitment system and include the required documents will be considered. We will review applications on a rolling basis, and the positions will be filled once suitable candidates are found.
