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). 

Requirements

We welcome applicants who don't tick every box. If you are motivated and willing to learn, we encourage you to apply. 

Essential 

• A genuine interest in science, chemistry or how things are made. 

• Careful attention to detail and the ability to follow written instructions precisely. 

• Reliability and good timekeeping. 

• Comfort with practical, hands-on work, including standing for periods and lifting and moving containers safely. 

• Good communication, and willingness to ask questions and speak up. 

• Basic computer skills for recording data, such as Excel. 

Desirable 

• GCSE Maths and English at grade 4/C or above (or willingness to work towards them during the apprenticeship). 

• Any experience of practical work, such as school or college labs, manufacturing, a workshop or a kitchen. 

Benefits

Job Type: Full-time, London-based, Permanent
