Location: Royal Wootton Bassett
Job Description:

Process Engineer – Pyrolysis & Carbon Systems

Role Summary:

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.

You will 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, you will 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

What we are looking for:

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
