Today, precision medicine coupled with advanced diagnostics is taking over. However, those innovations in medicine come with an ever-increasing price tag driven by more expensive and complicated solutions — making them less accessible unless we do something about it.
Signatur Biosciences was established with the mission of making cutting-edge diagnostic tools accessible to more patients around the world. As a startup, we have developed a technology to profile complex molecular signatures in a single reaction using qPCR machines already in place in every biomedical lab around the world.
Signatur Biosciences is a startup with a remote workforce, predominantly in London, UK, and a laboratory facility in Liège, Belgium.
We're worried about accessibility in precision diagnostics and are building a team of individuals who share our passion for solving this problem through close collaboration and a sense of urgency. We're building a different kind of company, where employees think like owners, act with authority, and collaborate closely with one another.
We are seeking an experienced and highly motivated Scientist to join our laboratory team in Liège (full time, on site). In this role you will own the scientific development of our next-generation qPCR-based IVD kits — from assay design and feasibility through verification and validation — inside an ISO 13485 quality management system, against IVDR. You will join Signatur Biosciences at an exciting time as we scale our Belgian facility and move our first products towards the market. If you are a self-starter who combines scientific rigour with real project ownership, we'd love to speak with you!

About the Role
As a Scientist, you will be responsible for translating project objectives into detailed and accurate protocols and work instructions, performing molecular biology techniques, analysing experimental data, and ensuring the highest standards of quality and accuracy — with a strong degree of autonomy. The role requires proven project management experience and a solid track record in the development of PCR-based products, combined with the ability to translate scientific rigour into practical, compliant laboratory outcomes aligned with regulatory requirements.

Main Responsibilities
Kit Development & Project Management
Contribute to the development of PCR-based diagnostic kits under IVDR, from design and feasibility through verification and validation
Plan, coordinate and manage development projects, ensuring timelines, resources and deliverables are met
Design, execute and interpret qPCR experiments and nucleic acid extraction protocols; troubleshoot experimental issues and lead investigations of unexpected results
Perform qPCR experiments manually or using high-throughput liquid handlers (e.g. the i.DOT platform)
Apply a "right-first-time" mindset to experimental design and execution
Work across the R&D team to anticipate reagent and consumable needs, and proactively remove barriers to project execution
Documentation & Quality
Write and review study plans, protocols, work instructions and laboratory records in accordance with ISO 13485
Write and review development plans and reports in accordance with IVDR requirements
Ensure adherence to laboratory procedures and support ISO 13485 compliance across all development activities
Contribute to the continuous improvement of laboratory processes in accordance with In Vitro Diagnostic development requirements
Take ownership of data analysis and report writing
Cross-functional Collaboration & Team Support
Liaise with the Product Lead to align kit development activities with the product roadmap and requirements
Collaborate with the RAQA Lead and the Head of Laboratory Operations to support compliant, well-documented development outcomes
Contribute to building scientific capability and knowledge-sharing across the laboratory team
Train the laboratory team on study protocols and work instructions, and act as subject matter expert for specific laboratory processes and equipment

Essential Skills & Experience
Master's, PhD or equivalent degree in Molecular Biology, Biotechnology, Bioengineering or a related scientific field
Significant experience (3–5 years) in molecular biology / qPCR laboratory environments, including hands-on PCR-based assay or kit development (not including coursework)
Hands-on experience developing products inside a regulated environment for in vitro diagnostics, medical devices or clinical diagnostics — including design control, risk management, and verification and validation
Proven project management experience, with the ability to plan, coordinate and drive development projects to completion in a regulated environment
Strong autonomy and sound scientific judgement
Strong writing and reviewing skills for plans, protocols and reports
Excellent scientific communication skills
Fluent in English & French
Desirable Skills & Experience
Experience working within a Quality Management System for In Vitro Diagnostic or medical device development (ISO 13485), and familiarity with IVDR requirements
Experience developing IVDR-compliant PCR-based diagnostic kits, from design through verification and validation
Experience in a start-up or fast-paced biotech environment
Experience in nucleic acid extraction
Experience mentoring or training laboratory technicians
Experience in using automated PCR set-up and liquid handling platforms
Data analysis literacy, ideally with a scientific programming language (Python, R, MATLAB or Julia)
Knowledge of biobanking requirements and international protocol standards (e.g. CLSI)
Confident use of AI tools to accelerate documentation, data analysis and literature review
Key Competencies
Planning and Problem Solving
Sense of Urgency and Focus
Teamwork & Communication
Attention to Detail & Continuous Learning
AI Curiosity & Tool Fluency

Compensation and Benefits
Competitive base salary (compensation will be based on experience level with requested qualifications)
Paid time off policy that includes 4 weeks plus 12 compensatory days
