Solvent Modelling & Thermodynamics

• Build and own the development of solvent models, including thermo-kinetic, property and thermal degradation models
• Validate models using lab data and continuously refine them to improve predictions
• Be able to accurately interpret experimental data, engage with experimentalists to improve data quality, and identify datasets needed to build and improve models
• Drive the building of accurate activity coefficient models for novel solvent formulations, identifying the best approaches and proactively overcoming technical challenges
• Implement solvers and optimisers to regress large-parameter models against experimental data

Experimental Collaboration & Model Validation

• Collaborate with experimental teams to design experiments and specify datasets and studies that support model validation and improvement
• Proactively prepare simulation plans in support of project goals
• Perform post-processing and data analysis using your knowledge of reaction engineering and thermodynamics

Innovation & Continuous Improvement

• Keep up with the literature and apply novel approaches and reaction schemes to improve model fidelity and predictive capability
• Play an integral part in idea generation, driving process innovation and intellectual property generation for Carbon Clean

Communication & Stakeholder Engagement

• Prepare figures, reports and presentations documenting project results
• Present results regularly to internal and external stakeholders
• Engage proactively with stakeholders, offering thoughtful, well-communicated solutions tailored to their requirements

You are an ideal candidate if...

• You hold a Ph.D. in Chemical Engineering or a related discipline with relevant thesis work, plus at least 2 years of relevant research experience in an industrial setting (3-4 years preferred)
• You have built thermo-kinetic models for multi-component polar, non-ideal mixtures, ideally in CO₂ capture or gas treating applications
• You have 2+ years' experience in solution thermodynamics modelling of non-ideal, polar, reactive mixtures using gamma-phi approaches with Electrolyte NRTL (preferred) or SAFT
• You have built, solved and optimised robust kinetic models that incorporate fundamental process chemistry
• You have used off-the-shelf optimisers (e.g. HEEDS, SciPy, Pyomo) to fit large-parameter models (100+ parameters) to experimental data
• You are proficient in Python and process simulation software such as AVEVA Process Simulation, Aspen Plus, gPROMS or similar
• You have led projects and provided technical mentoring in an industrial R&D setting
• You are comfortable working with a global team across UK, US and India time zones
• You are self-motivated and self-reliant, with excellent written and verbal communication and problem-solving skills

The application journey has 4 key steps

1. Recruiter call (initial 30 mins conversation)
2. Technical interview with the Hiring Manager
3. Technical case study or presentation with the E&PR team
4. Final interview with senior leadership

This process should take around 3-4 weeks - your schedule is really important to us, so we promise to be as flexible as possible!

Why join us?
