Requirements

What you’ll need

Ph.D. in Chemical Engineering or a related discipline with relevant thesis work.
At least 2 years of relevant research experience in an industrial setting; 3–4 years preferred.
Experience building thermo-kinetic models for multi-component polar, non-ideal mixtures, ideally in CO₂ capture or gas treating applications.
2+ years' experience in solution thermodynamics modelling of non-ideal, polar, reactive mixtures using gamma-phi approaches with Electrolyte NRTL or SAFT.
Experience building, solving and optimising robust kinetic models incorporating fundamental process chemistry.
Experience using off-the-shelf optimisers such as HEEDS, SciPy or Pyomo to fit large-parameter models (100+ parameters) to experimental data.
Proficiency in Python and process simulation software such as AVEVA Process Simulation, Aspen Plus, gPROMS or similar.
Experience leading projects and providing technical mentoring in an industrial R&D setting.
Comfort working with a global team across UK, US and India time zones.
Self-motivated and self-reliant, with excellent written and verbal communication and problem-solving skills.
