We’re hiring a Senior Protein Scientist in London for a full-time position with a salary of £55,000 – £65,000 + stock options. Are you passionate about cutting-edge reprogramming protein science and ready to make a big impact? We’re looking for a Senior Protein Scientist to lead our recombinant protein expression program as part of our molecular biology team. If you’ve tackled a range of protein expression challenges and have the first-author publications to prove it, we’d love to hear from you.
You’ll be a key contributor to our discovery efforts and central to understanding and engineering our newly identified reprogramming factors. This is a high-impact role with scope to shape strategy and build capabilities in a fast-moving and well-resourced biotech environment.
About Us
We’re a VC-backed biotech spun out of a Nobel lab at the University of Cambridge, focused on using epigenetic reprogramming to rejuvenate immune cells. Our mission is to restore function in HSCs and T cells for therapeutic applications in transplantation and cancer immunotherapy. Our platform is built around a novel and powerful reprogramming mechanism that we believe could redefine what’s possible in longevity science.
What You’ll Do
- Lead recombinant expression projects across unusual proteins in mammalian and bacterial systems
- Design and troubleshoot protein constructs, purification pipelines, and characterisation workflows
- Purify proteins using His-tag, SEC (AKTA), and other systems
- Optimise expression for a variety of protein types (secreted, cytoplasmic, nuclear, etc.)
- Drive protein engineering and screening strategies to enhance function
- Contribute to strategic decisions on expression platforms and discovery pipeline acceleration
- Work closely with a cross-functional team of 12 scientists in a collaborative, ideas-first culture
We’re Looking For
- PhD (or equivalent experience) in protein biochemistry, molecular biology, synthetic biology, or related
- First-author publication in a high-impact journal in protein science or molecular biology
- Real-world experience in recombinant protein expression and purification across diverse systems
- Familiarity with construct design, molecular cloning (Golden Gate, Gibson, etc.), and troubleshooting
- Ability to manage complex, multi-step expression workflows with attention to detail
- Comfortable expressing and optimising a range of protein types and characteristics
- Strong communication and collaboration skills—team-first mindset with scientific independence
- Intellectually curious, proactive, and driven to solve hard biological problems
Bonus Skills
- Protein engineering or structural modelling
- Experience with stem cells or cellular reprogramming
- Lentiviral or transposon-based delivery
- Familiarity with qPCR, NGS prep, and data-driven workflows
- Use of electronic lab notebooks (ELNs) and modern lab management tools
What We Offer
- Competitive salary: £55,000–£65,000, based on experience
- Equity options in a rapidly growing biotech
- 28 days holiday + public holidays
- Private healthcare
- Company-matched pension
- A voice in an early-stage team where your work will shape the science
- A mission-driven culture with scientific excellence, creativity, and integrity at its core
