This is an exciting opportunity to join an early-stage, mission-driven team at the forefront of computational biology. With data at the core of their strategy, you’ll play a critical role in shaping how science and technology intersect to deliver meaningful impact.

Why Join?

• Impact – Your work will directly contribute to life-changing innovations in biotech, from discovery through to development.
• Innovation – Apply cutting-edge data science to some of the hardest problems in biology, combining computational methods with experimental research.
• Growth – As part of a scaling Series A company, you’ll gain ownership, exposure, and the chance to help define the future data science function.

About the Role

We are seeking a Data Scientist to join the growing team. You’ll design, implement, and optimise machine learning models and analytical workflows to extract insights from complex biological datasets. Your work will accelerate R&D, optimise experiments, and support the development of new biotech products and therapies.

This role is ideal for someone who thrives in a fast-paced, collaborative environment and is motivated to apply data-driven approaches to solve real-world biological challenges.

Key Responsibilities

• Build and apply machine learning and statistical models to biological datasets (genomics, transcriptomics, imaging, clinical, etc.).
• Develop predictive models to guide experimental design and inform decision-making.
• Perform statistical analysis and ensure robust validation of results.
• Work closely with biologists, engineers, and clinicians to translate scientific challenges into computational solutions.
• Communicate findings to both technical and non-technical stakeholders through clear reports and visualisations.
• Contribute insights that shape R&D direction and product development.

Infrastructure & Tools

• Improve data pipelines and ensure data integrity in collaboration with engineering teams.
• Help shape the company’s data science toolkit, best practices, and standards.
• Document models, workflows, and methodologies to ensure reproducibility.

Required Qualifications

Technical Skills

• Degree (Master’s/PhD preferred) in Data Science, Statistics, Computer Science, Computational Biology, or a related field.
• Proficiency in Python and/or R, plus SQL for handling large datasets.
• Strong knowledge of statistical modelling, machine learning, and data visualisation.
• Experience with BI or data science tools (e.g. Jupyter, Tableau, Power BI, Looker).
• Bonus: familiarity with biological datasets (genomics, proteomics, clinical).

Business & Science Acumen

• Ability to frame biological research questions into data science problems.
• Strong grasp of experimental design and statistical validation.
• Experience in fast-paced, research-driven environments.

Soft Skills

• Excellent communicator, able to translate complex insights clearly.
• Highly detail-oriented with strong problem-solving ability.
• Comfortable working independently and in collaborative cross-functional teams.
• Motivated by the challenges and opportunities of an early-stage startup.

Preferred Qualifications

• Experience working in a biotech, life sciences, or healthcare data setting.
• Familiarity with cloud platforms (AWS, GCP, Azure).
• Knowledge of data engineering, pipelines, or workflow automation.
• Previous experience in a startup environment (Series A–B).
