Your Job

To expand our team “Process and Systems Assessment”, we are looking for several Postdocs or Senior Scientists with varying areas of expertise. Our research combines process modeling with techno-economic analysis, life-cycle assessment, mathematical optimization, process-oriented modeling of industrial energy systems, and the analysis of regulatory frameworks. In particular, we focus on chemical hydrogen carriers across their entire life cycle (synthesis, transport, conversion, application) as well as their supply chains and reference systems.
Depending on your expertise, you will take on responsibilities in one or more of the following areas:

Techno-Economic Analysis and Life Cycle Assessment (TEA/LCA)

• Develop and apply methods for techno-economic analysis (TEA) and life cycle assessment (LCA) of chemical hydrogen carriers and related industrial processes, including scenario, sensitivity, and uncertainty analyses to support technology development
• Advance evaluation frameworks for integrating process simulation with system-level TEA and LCA, establishing a closed loop between process and system modeling

Regulatory Frameworks and Energy Policy Assessment

• Analyze regulatory frameworks for hydrogen technologies, Power-to-X, chemical hydrogen carriers, and CO₂ infrastructures, as well as energy policy instruments including, e.g., electricity procurement models, power purchase agreements, grid tariffs, and sustainability criteria and assess their impact on technology deployment and value chains
• Translate regulatory requirements into quantitative modeling and evaluation criteria for system-level impact assessment and derive scientifically sound recommendations for technology, infrastructure, and policy development

In addition, your responsibilities as a Postdoc/Senior Scientist include:

• A completed university degree in a relevant field, such as process engineering, chemical engineering, energy engineering, mechanical engineering, industrial engineering, computer science, environmental sciences, mathematics, economics, energy economics, or a related field
• A completed Ph.D. or comparable, multi-year scientific or industrial experience
• Proven expertise in at least one of the following areas: techno-economic analysis (TEA), life cycle assessment (LCA), energy systems, mathematical optimization, process modeling/simulation, system analysis, or energy policy and regulatory assessment.
• Interest in chemical hydrogen carriers, Power-to-X, industrial energy systems, and sustainable industrial transformation
• Experience with quantitative methods, scientific modeling, and programming (e.g. Python, Julia, MATLAB, GAMS, Pyomo, or similar)
• Excellent English skills; German is an advantage
• Independent, analytical, and collaborative working style

• Experience with quantitative methods, scientific modeling, and programming (e.g. Python, Julia, MATLAB, GAMS, Pyomo, or similar).
• Excellent English skills (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level. Knowledge of the German language is an advantage.
• Independent, analytical, and collaborative working style.

Experience in one or more of the following areas is particularly welcome:

• Industrial energy system modeling and optimization, including temporal or spatial aggregation
• Process-integrated TEA/LCA and prospective technology assessment
• Hydrogen, chemical hydrogen carriers, Power-to-X, and CO₂ utilization, and related international value chains
• Energy policy, regulatory instruments, sustainability certification, and carbon accounting
• Multi-objective, robust, or stochastic optimization
• Coupling of process, site, and energy system models

Your profile doesn’t fully match?

We are looking for several candidates with different areas of focus. Therefore, your expertise does not need to cover all research areas listed above. We encourage you to apply if you have in-depth expertise in at least one of the fields listed above and are interested in working on academically challenging research questions.

In your application, please describe:

• Your previous academic focus
• The methods and topics in which you have expertise
• Which research questions you would like to address in the future, and
• How you would like to contribute and further develop your expertise in our team.
