R&D Engineer

Would you like to develop your career further in an innovative and truly international company working in the cutting-edge fields of the Green Energy transition, Biogas, Carbon Capture, and PtX?

Then you might be our new R&D Engineer in Ammongas, a strategic pillar in European Energy's business portfolio.

Ammongas tailors solutions to our customers who wish to produce green biofuel and green CO2. We have entered new markets as many countries are looking for Danish solutions to help them on their way to a green energy transition, driven by national and international project developers ranging from farmers to large energy groups.

Your new role

The Design & Technology Department is responsible for delivering high‑quality basic and detailed engineering in Ammongas. The department supports the company through new technology development, technology improvements, troubleshooting, and optimization of existing plants/technologies.

Within the department, the Process Team focuses on developing, maintaining, and applying advanced modelling tools to simulate and evaluate the performance of Ammongas technologies. This includes Carbon Capture systems, biogas upgrading/polishing, and Liquefaction plants. The team also collects operational data, validates models, and builds fast‑estimation tools to support design choices, cost evaluations, and technology development.

The R&D Engineer plays a key role in maintaining Ammongas' technical leadership by driving modelling accuracy, supporting innovation, and contributing to technology optimization and development.

Key responsibilities

Process Simulation & Technical Development

• Perform, maintain, and standardize PROMAX process simulations for carbon capture, biogas upgrading, and LCO₂ systems.
• Develop and maintain simulation templates, documentation structures, and modelling standards.
• Prepare mass and heat balances, technical descriptions, and design basis documentation for proposals, detailed engineering, and R&D work.
• Collect, structure, and analyse plant data for model validation, troubleshooting, and development of fast estimation tools.

Sales & Project Support

• Contribute to the development of design estimation tools and technology‑selection methodologies.
• Support the preparation of technical offers, feasibility assessments, and equipment layouts.
• Participate in meetings and technical discussions with clients and partners, clearly communicating Ammongas' design principles and performance expectations.

Engineering & Design Collaboration

• Contribute to the standardization and modularization of Ammongas plant designs, including pumps, reboilers, instrumentation, and packed column configurations.
• Participate in procurement, manufacturing follow‑up, erection, commissioning, and troubleshooting—particularly for first‑of‑a‑kind or complex installations.

Research & Development (R&D)

• Support ongoing R&D projects, including new solvent testing, column optimization, debottlenecking, and technology scaling.
• Identify opportunities for efficiency improvements, cost reductions, and product standardization.
• Drive independent development tasks and take ownership of designated R&D subprojects.

Job prerequisites

Technical Skills

• A Bachelor's or master's degree in chemical engineering, Process Engineering, Energy Technology, or a related technical field.
• Understanding of chemical engineering principles: mass transfer, heat transfer, reaction kinetics, thermodynamics, process control, and system modelling.
• Experience with chemical process modelling with PROMAX or similar process simulation software.
• Ability to interpret and develop P&IDs, process flow diagrams, and engineering calculations.
• Experience or familiarity with: 3D modelling in for example AutoDesk Plant 3D.

Personal Attributes

• Strong analytical mindset and attention to detail.
• Proactive, structured, and able to manage tasks independently.
• Strong communication skills and the ability to collaborate across departments.
• Eagerness to learn, innovate, and contribute to technology development.

With us you get

• To be part of a rapidly growing company at the core of the green transition.
• Testing theory in a modelling environment and in the field
• The possibility to work in an entrepreneurial environment where gaining hands-on experience is encouraged, while at the same time, new ideas and proactivity are valued.
• To be part of a company where colleagues have respect for each other, their time, and their ideas.
• Ample possibilities to engage socially across the departments. We have a monthly Friday get-together as well as sports events such as a running-, football-, and mountain bike club.

About Ammongas A/S

Ammongas is a Danish producer of environmental facilities, established in 2002 with more than 40 plants in Northern Europe and four in the US, with two more underway in 2024. The plants are designed and built by our dedicated engineers focusing on sustainability, economy, efficiency, and operational reliability in biogas upgrading, biomethane polishing for CH4 liquefaction, CO2 liquefaction, and carbon capture.

Ammongas was acquired by European Energy in 2022 with the purpose of facilitating new possibilities in the development of biogas upgrading and carbon capture in Denmark and abroad.
