Who we are

Siftr Bio is on a mission to reimagine targeted cancer therapies and develop groundbreaking drugs with substantially reduced side-effects that will improve the quality of life for millions of patients. Launched in 2024 from the renowned academic labs of Prof. Ed Tate at Imperial College London, we are moving at pace to disrupt one of the hottest areas of biotech: antibody-drug conjugates. Our cutting edge technology is backed by a syndicate of US-based investors, UK charities like Cancer Research UK, and leading figures in the ADC field. We’re assembling a multidisciplinary team of world-class scientists and innovators at our lab-space in the White City Innovation District who share our ambitious goals and thrive in an entrepreneurial, fast-paced startup environment.

In this role, you’ll work directly with the founders and a focused scientific team to shape and execute our R&D programs ー from the design and synthesis of novel ADC linker-payloads to the development of cell-based assays.

You should be an adaptable, interdisciplinary scientist who is excited to contribute across scientific domains and be able to iterate quickly as our platform evolves. As an early employee of a fast-moving startup, we expect you to play a key role in shaping the science, processes, and culture that determine our success.

• Support the wider team in designing and implementing lab processes for a safe and efficient research environment

Who you are

• Strong practical skills in at least 3 of the following areas: organic synthesis, peptide synthesis, cell culture, assay development, bioconjugation
• A proactive scientist with a proven ability to take ownership and drive projects forward
• Someone who relishes the challenge of building a company from the early-stages
• Must already have the right to work in the UK

What’s in it for you

• A unique opportunity to take significant responsibility at an early-stage startup, with opportunities for rapid advancement as the company scales
• Exposure to a fast-paced start-up environment where your work on complex scientific challenges directly translates into patient impact
• Join a company at the forefront of innovation in the exciting area of antibody-drug conjugates
• Opportunity for direct collaborations with leading multidisciplinary scientists in Prof. Ed Tate’s group at Imperial College
