About the role
Thermulon is a UK aerogel insulation company developing a cost-competitive manufacturing process. We are scaling from pilot into commercial-scale production to serve European and global customers.
The Apprentice Process Technician will learn to run Thermulon's 25 L pilot reactor from start to finish: preparing the chemicals, carrying out the reactions and producing a finished aerogel powder. You'll then handle and test that powder, measuring properties such as thermal conductivity and density. This is a hands-on role in a small, lean organisation, where you'll be trained on the job by our chemists and engineers while working towards a nationally recognised Level 3 Laboratory Technician qualification.
No degree or previous lab job is needed. We are looking for someone curious about science, careful with detail and keen to learn a hands-on technical trade.
Location: Thermulon laboratories, Westbourne Studios, London W10
First round interviews will take place w/c 16th November
What this role needs from you
You'll live Thermulon's Values: Safe, Collaborate, Impact, Pace, Innovate and Grow. In practice that means:
- A careful, safety-first approach: following procedures closely and speaking up if something doesn't look right.
- Enjoyment of working as part of a team, sharing the workload and helping colleagues.
- Pride in doing a job properly, because others rely on your results.
- Genuine energy for hands-on work, and seeing a task through to the finish.
- Curiosity about why things work, and willingness to suggest better ways of doing them.
- Keenness to learn, take on feedback and build a long-term technical career.
Key accountabilities
With full training and supervision, building up to working independently, you'll:
- Handle chemicals in line with risk assessments, COSHH and PPE rules, and keep the work area clean and organised.
- Run batches on our 25 L pilot reactor from start to finish, including weighing and preparing reagents and stock solutions, charging the reactor, and carrying out and monitoring the reaction through to finished powder.
- Work to Standard Operating Procedures (SOPs) and batch records, recording process data accurately at every step.
- Sieve, weigh, blend, package and label aerogel powder safely, keeping dust and contamination under control.
- Measure product properties, including thermal conductivity and bulk and tapped density, and log the results
- Track powder stock, transfers and shipments, keep inventory and batch records up to date, and enter data into our Laboratory Information Management System (LIMS).
- Set up, clean and carry out routine checks on the reactor, sieves and test equipment.
- Flag problems and deviations early, and suggest improvements to procedures.
Your apprenticeship
You will complete the Level 3 Laboratory Technician apprenticeship, delivered by Skills4Science, over about 18 months: 15 months of training plus the final assessment.
- Weekly 2-hour live online teaching sessions on Microsoft Teams, during your paid working hours.
- A dedicated Skills4Science tutor, plus a workplace mentor at Thermulon.
- On-site observations and progress reviews every 10–12 weeks.
- Most of your learning happens on the job: learning new techniques, equipment training, shadowing colleagues and project work.
- Support to gain GCSE-level English and Maths if you don't already have them.
- On completion, you'll be eligible to register with the Science Council as a Registered Science Technician (RSciTech).
