## Description

Promatica Digital is a healthcare software company whose platform supports NHS primary-care services. We're building a new module in our core platform and need an experienced full-stack developer with strong React and C# / .NET skills to help design and deliver it end to end.

This is a hands-on, delivery-focused role on a defined piece of work, with potential to extend beyond the initial 12 months. You'll build features across the whole stack: React user interfaces, .NET APIs and services, and the SQL Server data layer behind them, all hosted in Azure.

What you'll do

 * Design, build and ship features for a new module in our core platform, from the user interface through to the database.
 * Build responsive, accessible front ends in React and TypeScript.
 * Develop secure, well-structured APIs and back-end services in C# / .NET.
 * Design data models and write efficient T-SQL in SQL Server.
 * Write clean, well-tested, maintainable code and clear technical documentation.
 * Work closely with our existing developers, clinicians and stakeholders to turn requirements into working software.
 * Ensure sensitive and patient data is handled securely and in line with information-governance requirements.
