Are you an AI Research Scientist passionate about using LLMs and machine learning to reshape how organisations understand people?

We’re looking for a curious and pragmatic AI Research Scientist to join a remote team building the next generation of AI-powered insight tools. You’ll be working on a real-world research platform already in production — now expanding into new territory with retrieval-augmented generation (RAG), vector search, and intelligent automation.

In this role, you’ll help reimagine how unstructured and structured data from large-scale surveys and discussions can be turned into clear, actionable insight using advanced AI. From redesigning RAG stacks to building AI-powered report writers and secure vector stores, you’ll be solving rich, challenging problems at the intersection of NLP, data infrastructure, and human understanding.

Whether you’ve shipped AI features before or have strong personal research and projects, this is a chance to shape products used by real researchers and clients every day.

What’s in it for you?

• Design and conduct experiments to investigate biological pathways and identify potential drug targets.
• Develop and validate new assays and experimental models.
• Analyze and interpret complex experimental data, employing statistical methods.
• Collaborate with cross-functional teams, including medicinal chemists, pharmacologists, and toxicologists.
• Contribute to the preparation of research reports, scientific publications, and regulatory submissions.
• Maintain accurate laboratory records and ensure compliance with Good Laboratory Practices (GLP).
• Stay informed about the latest scientific advancements and emerging technologies in the pharmaceutical industry.
• Troubleshoot experimental procedures and equipment.
• Present research findings at internal meetings and external scientific conferences.
• Manage laboratory resources and contribute to a safe and organized work environment.

• PhD or Master's degree in Pharmacology, Biochemistry, Molecular Biology, or a related life science discipline.
• Proven experience in drug discovery research, preferably within the pharmaceutical or biotechnology sector.
• Hands-on experience with various molecular and cellular biology techniques (e.g., cell culture, PCR, Western blotting, ELISA).
• Strong analytical skills with the ability to interpret complex data sets.
• Excellent written and verbal communication skills, with a track record of scientific publications.
• Ability to work independently and collaboratively in a team-oriented environment.
• Proficiency in data analysis software (e.g., GraphPad Prism, R) is an advantage.
• Familiarity with regulatory guidelines (e.g., GLP, GMP) is desirable.
• Strong problem-solving abilities and attention to detail.
