Material Research Assistant

Recircle is a UK-based industrial biotechnology company focused on sustainable solutions for the rubber materials sector. Recircle has developed technologies that combine biotechnology with polymer chemistry and industrial process engineering to allow waste rubber to be reprocessed into high quality materials for re-use in new rubber goods. We're committed to building a world without waste. Our company culture is central to everything we do.

We invest heavily in our people, personal development, and long-term career growth opportunities.

Recircle are looking for a motivated, hands-on scientist with a strong chemistry background and a genuine interest in rubber materials. You don’t need to know everything - we have an experienced team ready to train and support you
-but you should be comfortable working in a laboratory, eager to learn, and able to apply scientific thinking to practical problems.

This role is ideal for a chemistry or materials science graduate with 1–3 years of lab experience who wants to develop specialist skills in rubber analysis, testing, and compound development.

The successful candidate will play an active role in supporting laboratory research, conducting experiments, and ensuring smooth day-to-day lab operations. We are looking for a dynamic, enthusiastic, and self-motivated individual who shares our values and is eager to learn, grow and adapt within a fast-paced and dynamic research environment.
