Research Scientist/Senior Scientist - Protein Sciences

About Maxion 

Maxion Therapeutics is a pioneering biotechnology company dedicated to developing groundbreaking biologic medicines for diseases with unmet needs, driven by ion channel and GPCR dysfunction. Our innovative KnotBody technology empowers us to create potent, selective, and durable antibody therapeutics. This technology merges millions of years of cysteine-rich miniprotein ('Knottin') evolution with cutting-edge antibody engineering, addressing pivotal challenges in ion channel/GPCR drug discovery.

Situated at Unity Campus in Cambridge, UK, Maxion Therapeutics fosters a dynamic and forward-thinking work environment underpinned by our scientific founders, who are trailblazers in antibody engineering. Led by our CEO, Dr Arndt Schottelius, our experienced leadership team boasts a stellar track record. Dr Schottelius has held senior leadership positions, successfully advancing therapeutics from research to late-stage clinical development, and building valuable portfolios of drug candidates and pharma partnerships.

Our co-founders, Dr John McCafferty (CTO) and Dr Aneesh Karatt Vellatt (CSO), previously co-founded IONTAS, and together invented KnotBody technology. Dr McCafferty is also renowned for co-inventing antibody phage display, which contributed to the 2018 Nobel Prize in Chemistry (awarded to his co-inventor Sir Gregory Winter), and co-founding Cambridge Antibody Technology.
