Senior Full-Stack Software Engineer

About Portal Biotech
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 with it. 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.

About the Role
We are seeking two Senior Full-Stack Software Engineers to join our Analysis Platform team. You'll design and build the backend services, UI and deployment infrastructure that power the platform scientists use to launch analyses, follow runs and interact with reports from our analysis pipeline.

• Design and implement services to launch and manage data analysis workflows, serving both internal teams and external users
• Work with and support the React front-end developers to design APIs and contribute to UI implementation
• Automate system deployment to Azure
• Review and refine product requirements, software design and test cases
