Development Scientist – Biological Kits
About Us:
Portal Biotech has built the world’s only platform capable of sequencing full-length proteins at the single-molecule level. Using our nanopore technology, we read intact proteins of any size, capturing both sequence and post-translational modifications in a way no other system can. This opens up entirely new ways to understand protein biology, with applications across drug discovery, diagnostics, and biosecurity.
Our technology works and customers are engaging. We’re now focused on scaling, turning breakthrough science into products that deliver real biological insight as we move beyond Series A towards global product launch.
Position Overview:
We are seeking Development Scientists to join our Product Development efforts as part of our DevOps team, based at our headquarters in Scale Space, White City, London. This role spans early feasibility studies through to longer-term biological product development.
You will design and run focused experiments to optimise biological products and workflows, generating clear, well-controlled data to guide technical decisions. Promising prototypes will be matured into reliable, reproducible solutions integrated into our platform, directly supporting the journey from concept to viable product.
This is a hands-on laboratory role suited to someone who enjoys solving practical scientific problems and building solutions that are robust, transferable, and fit for real-world use within a collaborative, multidisciplinary team.
