Job Description

Laboratory Research Scientist – Molecular Biology & Metagenomics

Waltham, Leicestershire | Full-Time

At the heart of our research centre in Waltham, we’re building something exciting — a world-class scientific capability that blends high-throughput sequencing with bespoke, non-routine experimentation. As a Laboratory Research Scientist, you’ll be hands-on with next-gen sequencing, shaping the way we understand the microbiome, metagenomics, and beyond.

Key Responsibilities

• Lead and run advanced molecular biology experiments, including next-generation sequencing (NGS) and metagenomics workflows.
• Split your time between routine pipeline excellence and exploratory scientific discovery — no two weeks are the same.
• Build, optimise, and validate new test methods, tools, and assays to keep us on the leading edge.
• Own and manage lab spaces, ensuring they run smoothly and evolve with the science.
• Generate and interpret robust, high-quality data that supports impactful decisions and discovery.
• Use digital tools like LIMS and electronic lab notebooks to keep our research connected and current.
• Mentor colleagues and champion scientific best practices within the lab community.
• Collaborate with multidisciplinary teams to share insights and drive continuous improvement.
  
  

What We’re Looking For

• A BSc in Biochemistry, Biology, Molecular Biology, or related life sciences field.
• A PhD in Molecular Biology, Molecular Microbiology or equivalent hands-on experience in industry.
• Proven expertise in molecular techniques, especially NGS (Illumina NextSeq is a plus).
• Hands-on metagenomics experience, ideally involving large-scale sample processing.
• Confidence working in dynamic, complex research environments with changing priorities.
• Sharp analytical skills, attention to detail, and the curiosity to solve scientific puzzles.
• Experience with LIMS systems and digital lab documentation tools.
• A growth mindset — you're here to learn, lead, and leave a mark.
  
  

Why Join Us?

• Be part of a trailblazing team solving complex biological challenges with real-world impact.
• Get the best of both worlds: the rigour of operational excellence with the thrill of scientific discovery.
• Help shape the future of molecular microbiology and metagenomics in an organisation that values innovation, learning, and collaboration.
• Competitive salary, comprehensive benefits, and a truly supportive team culture.
