Process Engineer
Innargi is looking for an experienced process engineer to strengthen our Engineering team during a period of rapid project growth.
The role will support the development and execution of large-scale geothermal and district heating facilities, with a particular focus on process systems, heat pump integration, equipment selection, and facility standardization.
As Process Engineer, you will help turn geothermal concepts into operating facilities. You will develop process designs, specify technical requirements for equipment and integrate everything into a functional plant.
Working across disciplines, you will coordinate interfaces, suppliers and contractors. Your involvement will span concept development, detailed design, construction and commissioning.
You will assess performance and technical risks, and support troubleshooting.
Key Competencies
Process and Facility Engineering
You will design industrial process systems and energy facilities, specify and size equipment, and work on plant integration and system optimization. A key part of the role will be developing modular, standardized plant designs that can be applied across projects.
Heat Pumps and Energy Systems
You will work with large-scale heat pump applications and their integration into district heating systems. Drawing on energy system modelling and calculations, you will assess energy performance to support the development of efficient energy solutions.
Mechanical Systems
You will apply your knowledge of industrial piping systems and mechanical design to develop equipment layouts. Your responsibilities will also include technical evaluations of supplier proposals and support for commissioning and troubleshooting.
Project Execution and Technical Leadership
You will coordinate technical interfaces across disciplines and contribute throughout concept development, FEED and detailed design. The role will also involve managing suppliers and contractors and assessing technical risks to support project execution.
Preferred Experience
You bring approximately 8–15+ years of relevant engineering experience, ideally spanning concept development, commissioning and operations support. Your background includes district heating plant design and operation, geothermal energy systems, and process safety, including HAZOP or HAZID participation. You also have experience with equipment procurement, technical bid evaluations and engineering calculations in Excel and/or Python, as well as developing standard designs, modular solutions or repeatable engineering concepts.
The role is best suited to a Senior Process & Facility Engineer, Lead Process Engineer, or Lead Energy Systems Engineer who can take ownership of complex facility design challenges and help scale Innargi's standardized geothermal energy solutions while supporting both ongoing projects and future growth.
Personal Qualities
You bring a strong systems-thinking mindset and are comfortable working across disciplines. Pragmatic and solution-oriented, you balance technical depth with commercial awareness. You communicate effectively with engineers and non-technical stakeholders alike, making complex technical topics accessible to different audiences. You thrive in a fast-growing, project-driven environment.
Background
Innargi is a geothermal company delivering energy for heating, founded in 2017 by A.P. Moller Holding and today jointly owned by A.P. Moller Holding, ATP and NRGi. We have projects under development at different stages in Aarhus, Copenhagen, Poznań and Łódź.
We are a small entrepreneurial and highly energised organisation. We work hard and we have fun doing it. As a team, we see our different backgrounds and experiences as a genuine source of strength, and we respect each other’s technical and functional competencies.
Our structure is lean and flat. We believe strongly in value creation through empowering our employees, and you will have significant independence to impact your role, as well as be expected to collaborate across disciplines.
As Global warming continues to impact climate change, it’s time to rethink the way we heat our urban buildings. Innargi wants to heat millions of urban homes while striving to leave zero impact on our planet by unearthing geothermal energy.
Our natural world is precious, and we can all make small changes to the way we live. But what our climate really needs is change at scale. Solar and wind have already transformed how we produce energy. What those technologies have done for electricity, geothermal can do for heating.
Innargi has the team to make it happen. With our combined knowledge and expertise on subsurface, drilling, engineering, and energy planning and through close partnerships with local district heating companies, we are in a unique position to turn ambitious plans into real change.
The position will be based in Copenhagen, with traveling between our other locations.
