Job Description

We're building something new at the intersection of synthetic biology and advanced computation and we're looking for an exceptional scientist to join us.

We're an early-stage, venture-backed biotech operating in stealth while we develop a platform with the ability to redefine how complex therapies are designed and manufactured. Our team combines deep biological expertise with cutting-edge engineering, and we're now expanding our scientific capabilities as we move into our next phase of growth.

As a key early hire, you'll work closely with the founders to shape core scientific programmes, build foundational workflows, and solve technically demanding problems with real therapeutic impact. You'll have the freedom to explore ideas, design experiments, and contribute directly to the direction of the company, all while maintaining a high degree of ownership and influence.

What You'll Do

Develop and execute experimental work central to our platform. Build and scale core molecular biology workflows. Tackle complex scientific challenges using rigorous, first-principles thinking. Collaborate closely with founders and a small multidisciplinary team. Translate early discoveries into practical applications with industry relevance.

What We're Looking For

PhD (or equivalent experience) in molecular biology, synthetic biology, bioengineering, or related discipline. Experience with recombinant protein expression, vector engineering, and/or gene therapy systems. Strong grounding in molecular/cellular engineering (cloning, gene engineering, mammalian culture, cell line development). Skilled in experimental design, troubleshooting, and data interpretation. Thrives in collaborative, fast-moving, ambiguous environments. A builder's mindset: resourceful, thoughtful, and impact-driven.

What You'll Get

Competitive salary with meaningful equity. Full benefits package, including pension and private health insurance. 28 days' holiday + flexible working. Access to state-of-the-art labs in Victoria House, London's engineering biology hub, with regular social, health and fitness activities on-site. A rare chance to join a stealth biotech at the ground floor, shaping both the science and the culture from day one.

If you're excited by big scientific challenges, enjoy working with autonomy in a small team, and want to help build something important from first principles, we'd love to hear from you.
