Process Engineer – Pyrolysis & Carbon Systems
Own the performance, modelling, and validation of our pyrolysis systems at Royal Wootton Bassett, while contributing to their development and scale‑up across a broader carbon removal platform.
Work hands‑on with a live plant, combining process modelling, operational support and engineering judgement to optimise performance and improve system design.
As a multi‑skilled engineer within the site team, support operations, maintenance and safe systems of work, while helping turn a working plant into a repeatable system that delivers measurable climate impact at scale.
Why This Matters
We are building systems that remove carbon from the atmosphere and turn waste into a stable, long‑term carbon store. Royal Wootton Bassett is where these systems are proven, improved and prepared for deployment.
Your work will turn a working plant into a repeatable system that delivers measurable climate impact at scale.
THIS ROLE REQUIRES 3 - 4 DAYS ON SITE
Key Responsibilities and Accountabilities
Plant operation, maintenance and optimisation
* Work directly on our Royal Wootton Bassett pyrolysis facility
* Monitor, troubleshoot and optimise plant performance across varying conditions
* Support day‑to‑day operations and maintenance activities alongside the site team
* Assist with fault finding, basic maintenance tasks and system interventions where required
* Adjust process parameters based on real‑time performance and test outputs
* Support commissioning, integration and testing of new systems and upgrades
* Conduct flue gas analysis and use outputs to inform process performance and optimisation
Process modelling and system design
* Build and maintain process models using Aspen (mass and energy balance, system optimisation)
* Translate plant data into model improvements and design insights
* Support design and performance validation of new and existing pyrolysis systems
* Contribute to process design documentation, calculations and system specifications
Lab testing and material analysis
* Conduct hands‑on testing (e.g. moisture content, carbon content using muffle furnace)
* Analyse feedstock and biochar outputs to understand system performance
* Use lab data to inform process improvements and modelling assumptions
Engineering development and scale‑up
* Contribute to the design and development of new pyrolysis systems and projects
* Support technical reviews of technologies and external partners
* Participate in safety assessments (HAZOP, risk assessments) and change processes
Data, monitoring and MRV support
* Support the design and validation of monitoring, reporting and verification (MRV) systems
* Ensure process data can be accurately captured, interpreted, and used
* Work closely with the carbon team to ensure outputs are technically robust
Site systems, safety and team support
* Develop and maintain standard operating procedures (SOPs) and risk assessments (RAs)
* Support the development of safe systems of work and site documentation
* Contribute to training and upskilling of site personnel
* Ensure compliance with site procedures, permits and safety requirements
Core Requirements
* Degree in Chemical Engineering or a related discipline
* Experience in process engineering within industrial, energy, waste or chemical environments
* Strong grounding in heat and mass balance and process behaviour
* Experience with process modelling tools (Aspen strongly preferred)
* Comfortable working hands‑on in a plant environment
Technical Experience
* Experience with process safety (HAZOP, HAZID, risk assessments)
* Familiarity with CDM regulations and engineering project environments
* Exposure to control systems (PLC, HMI, DCS)
* Ability to interpret and work with process data and instrumentation
* Experience contributing to plant commissioning or modification
Valuable Experience (not Essential)
* Pyrolysis, thermal processes or energy‑from‑waste systems
* High‑temperature or solids‑handling processes
* CAD or engineering drawing review capability
* Lab testing, materials analysis or process validation work
* Chartered status or working towards it
You Will Love This Role If You
* Want to work on a real system and see the results of your work immediately
* Enjoy improving and refining processes through testing, data and iteration
* Are motivated by taking something that works and making it scalable
* Like combining hands‑on engineering with modelling and system thinking
* Care about building technology that has a clear, practical impact on climate
