Biophysics Engineer - Surface Functionalisation & Microfluidics

Company Overview

CT19 are partnering with an early-stage DeepTech, founded in 2023, who are developing a new approach to quality control in industrial environments (food and beverage, cosmetics, pharmaceutical manufacturing etc).

Traditional microbiological quality control methods often involve operational constraints and long waiting times for results and their platform is designed to detect bacterial contamination rapidly using advanced optical technologies and machine-learning approaches.

The team brings together expertise in biology, physics, engineering, and data science to build scalable solutions for industrial microbiology monitoring.

Role Overview

We are seeking a Senior Biophysics Engineer with strong expertise in surface functionalization and microfluidics . The successful candidate will lead the development and optimization of biofunctional interfaces, central to a microbial detection platform.

This role will focus on translating advanced biophysical principles into robust, scalable solutions suitable for industrial deployment, while expanding the range of applications supported by the technology.

Key Responsibilities

• Lead the design and optimization of surface functionalization strategies for microbial capture and detection.
• Develop, test, and refine microfluidic systems for sample preparation, reaction control, and signal detection.
• Optimize surface–biomolecule interactions to improve assay sensitivity, specificity, reproducibility, and stability.
• Design and execute experimental plans, analyze complex datasets, and derive actionable conclusions.
• Collaborate closely with biology, hardware, and software teams to ensure integrated system development.
• Support technology transfer, robustness testing, and scaling toward industrial implementation.
• Maintain clear technical documentation, contribute to intellectual property development, and support technical decision-making.

Required Qualifications

• PhD in Biophysics, Bioengineering, Physical Chemistry , or a related discipline.
• Minimum 3 years of industry experience in applied R&D or product development environments.
• Demonstrated hands-on experience with surface functionalization and biointerface engineering .
• Strong experience in microfluidics , including design, fabrication, prototyping, and testing.
• Solid understanding of biomolecular interactions and bioassay development .
• Ability to work independently and take technical ownership within a fast-paced development environment.
• Experience with biosensors, immunoassays, or rapid microbial detection technologies .
• Familiarity with surface characterization techniques such as AFM, SPR, contact angle measurement, or fluorescence-based analysis.
• Experience transitioning technologies from research prototypes to industrial or commercial systems .
• Exposure to regulated or industrial sectors such as food safety, diagnostics, or in vitro diagnostics (IVD)
