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.

• 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.
