Chemical Engineer with Polymer Membrane Research and Development Experience

Exactmer is a start-up dedicated to producing precision polymeric molecules with our patented Nanostar Sieving Technology. Using this disruptive new platform, we are creating exquisite synthetic and biological polymers, including oligonucleotides and mono-disperse polyethylene glycols (PEGs), ADC linkers, peptides and more…most of them bound for use in medicines that enhance patient quality of life.

We are a young, diverse team of around 35 people. London-based, we are in a rapid phase of growth and are searching for a self-starting, dynamic, flexible and committed individual to join our team. We are seeking an outstanding chemical engineer / chemist to work as part of a team delivering innovative membranes which are at the heart of our process.

You will deal with the fabrication of new polymer membranes for the separations in our Nanostar Sieving process. You will develop membranes first at small sheet A4 scale, and then through roll-to-roll processing, characterise the membrane morphology and performance, and examine their durability in processing. Excellent record-keeping and adherence to safety codes and protocols are essential. Overall, you need to be flexible and ready to grow your skills and experience as the company grows and our technology evolves.

Candidates should have experience of membrane research and development for example obtained through a PhD, with an interest in molecular separation. You should have a desire to learn fast and tackle many different aspects of creating a new technology and new products. Experience would be a bonus and we are open to candidates at different career stages.
