Sustainable Energy Engineer (Thermal Energy / District Heating)

Opis stanowiska

At Ramboll, we believe that engineering, consulting, and sustainability go hand in hand. With over 18,000 experts in 35 countries, we work on projects that make a real difference to people, the planet, and future generations.

In Poland, we’ve been active for over 30 years, particularly in the energy generation and gas transmission sectors. We help our clients transition to clean, modern, and resilient energy systems. Now, we’re looking for talented engineers and consultants to join us on this journey.

As a Sustainable Energy Engineer, you’ll play a central role in designing and optimizing innovative energy systems – from district heating and combined heat and power (CHP) plants to large-scale renewables and energy storage solutions. You’ll work alongside global experts to support both public and private clients in achieving their climate and decarbonisation goals.

What You’ll Do:

• Contribute to complex energy projects, supporting decarbonization, energy efficiency, and system integration.
• Develop sustainable thermal energy supply strategies, including low-carbon heat generation, district heating, and CHP.
• Conduct feasibility studies, energy system modelling, and techno-economic analyses.
• Support permitting and design processes for energy infrastructure projects.
• Prepare and review technical documentation, ensuring compliance with environmental and safety standards.
• Participate in the conceptual design of advanced energy systems such as heat pumps, energy storage, Power-to-X (PtX), and biogas plants.
• Collaborate across disciplines and geographies to deliver smart, scalable, and sustainable energy solutions.
• Help integrate sustainable energy solutions into urban planning and infrastructure developments.

Your Qualifications:

We’re looking for someone who combines strong technical expertise with a proactive, solution-oriented mindset.

You have:

• A university degree (MSc or BSc) in Energy, Mechanical, Process, or Environmental Engineering – or a related technical field.
• At least 5 years of relevant experience in the energy sector – ideally in thermal generation, district heating, renewables, or consulting.
• Solid understanding of sustainable energy systems and the broader energy landscape.
• Experience working with technical documentation and energy system analysis or modelling.
• Proficiency in MS Office (especially Excel); experience with Thermoflex, AutoCAD, or similar tools is a plus.
• Strong analytical, communication, and organizational skills.
• A collaborative approach and the ability to work across teams and time zones.
• Fluency in Polish and good command of English (min. B2 level).

What We Offer:

At Ramboll, we believe that our people are the foundation of our success. We offer a workplace where creativity, sustainability, and innovation are part of daily life.

• Accelerated career growth in a global company leading the energy transition.
• Meaningful projects with real impact on sustainable development and climate goals.
• Access to top industry experts, tools, and training programs tailored to your development.
• Hybrid work model – 3 days from our modern office, 2 days remote.
• Full-time employment contract – initial term of 1 year with long-term potential.
• Attractive benefits package: private healthcare, life insurance, holiday subsidies, and a cafeteria system.
• A vibrant team culture built on collaboration, knowledge sharing, and a shared mission for sustainability.
