Job summary

Signatur Biosciences in London is seeking a Senior Data Scientist to build data-driven capabilities from the ground up. You will report to the Chief Scientific Officer and shape how data is used across the company, including modelling for assay development and AI tooling.

Based in London with hybrid work and regular travel to Liège, Belgium, you will lead end-to-end data analysis, build reproducible pipelines, and drive a data-driven culture as the company grows.

Qualifications

• Minimum MSc or MRes in a quantitative, life sciences or related field
• Strong foundation in statistics and quantitative methods, with demonstrable experience applying them to real, messy datasets
• Hands-on experience applying machine learning to scientific, experimental or otherwise complex real-world data — not only to clean benchmark problems
• Proficiency in Python and SQL for data analysis
• Fluency with modern AI tools and a real drive to apply them to streamline work
• A track record of independently owning data work and driving it to real impact, rather than executing tasks handed to you
• Comfortable working independently in a fast-paced, high-ownership startup environment — taking pragmatic shortcuts and failing fast to learn quickly
• Self-motivated, ambitious and driven: anticipates problems and finds creative solutions to make things happen
• Right to work in the UK, or eligibility for UK visa sponsorship (available for this role)

Responsibilities

• Apply machine learning and statistical modelling to assay development data — signature selection, panel optimisation and performance prediction — working closely with the scientific team in Liège
• Lead end-to-end data analysis across the business, from exploratory analysis through to clear, actionable recommendations
• Help every team define and quantify what success looks like, build precise, measurable plans to reach it, and track progress closely, adjusting fast as things change
• Build lightweight, reproducible analysis pipelines and the shared data foundations the laboratory and development teams need to work from one source of truth
• Champion a data-driven culture and build the AI tooling that accelerates our own work — finding where AI genuinely removes effort, and making it usable by the rest of the team
• Communicate findings clearly to non-technical stakeholders, including leadership
