Job summary

Recircle is seeking a mid-senior Chemical Process Engineer to advance understanding and control of multiphase reactor systems in a rubber waste recycling context. The role requires hands-on lab work, strong problem-solving, and a drive to translate kinetics and mass transfer into scalable processes.

You will work with enzyme engineers and biochemists to optimise reactor configuration, mixing, aeration and solvent considerations, driving robust, scalable operation.

Qualifications

• MEng/MSc/PhD in Chemical Engineering or closely related discipline.
• Strong practical understanding of multiphase reaction systems (gas, liquid, solid).
• Hands-on experience with lab-scale stirred reactors and scale-up.
• Knowledge of mixing, solids suspension and reactor geometry.
• Understanding of mass-transfer phenomena in multi-phase systems.
• Experience with enzymatic or biocatalytic reactions is a plus.

Responsibilities

• Develop mechanistic understanding of the reaction system focusing on enzyme kinetics, mass transfer and phase behaviour.
• Optimise reactor configuration and hydrodynamics for multi-phase substrates.
• Handle solid rubber substrate, including wetting, suspension and agglomeration.
• Evaluate reaction media for substrate compatibility and downstream processing.
• Investigate interfacial phenomena to improve transport and interaction between phases.
• Improve oxygen transfer and aeration in multi-phase reactor setups.
• Compile system data to inform scale-up and process design.
