Cement Junior Laboratory Technician
Role type: Full-time, permanent
Location: In person - Cambridge, UK
About the Role
Reclinker is an early-stage deep-tech start-up, founded in 2022 to commercialise a world-first process for producing low-carbon, recycled cement using electric arc furnaces (EAFs) — the same technology used in steel recycling. Spun out of the University of Cambridge, we are on a mission to decarbonise one of the world's most carbon-intensive industries.
We are looking for people who are committed to - and consistently demonstrate - our company values of:
- Intellectually curious: Keen to learn and try something new.
- Open and humble: Open to new ideas, without ego.
- Collaborative: Ask for help and support each other.
- Data-driven: Query, find and follow the numbers.
- Have a sense of fun: Enjoy each other's company and our journey together.
- Autonomous: Self-motivated, manage ambiguity and take the initiative.
We are looking for a Junior Laboratory Technician to join our growing team. You will play a hands-on role in supporting our R&D and operations teams, helping us test, analyse, and develop the materials at the heart of our technology. No prior specialist experience is required — we will invest in your development. What matters most is a practical mindset, a genuine willingness to learn, and a strong personal commitment to safety.
About You
You’re a practical, detail-oriented laboratory professional who enjoys working in a fast-paced innovation and laboratory setting, taking ownership of the tasks that keep a lab running at its best. You’re confident handling routine maintenance, while remaining curious and capable enough to contribute to experimental and analytical work when the opportunity arises. You work autonomously and proactively, taking accountability for your tasks and seeing them through to completion.
