Senior Full Stack Engineer (React & .NET)
Remote (UK & Ireland)
Contract - 6 months+
Rate: £400-420 p/d (Outside IR35)
A fast-growing healthcare technology company is building an AI-driven SaaS platform used by organisations across the UK, Ireland, and Australia.
The product is live, scaling quickly, and entering a key growth phase with multiple new modules being built from scratch. This is not a maintenance role or a legacy rebuild - it’s a genuine product engineering opportunity in a modern SaaS environment.
The Role
We’re looking for true full stack engineers who are comfortable working across both frontend and backend, and who have experience delivering features end-to-end in SaaS or MVP-stage products.
You’ll work alongside experienced principal engineers, taking ownership of features from initial requirements through to production. This role requires a balanced skillset - building high-quality user interfaces as well as designing and delivering robust backend services.
Initial focus areas include:
* Building a new Audit module (scheduling, workflows, reporting)
* Developing Risk Register and Events modules as the platform scales
What You’ll Be Doing
* Owning features end-to-end across frontend and backend
* Building React (TypeScript) applications with clean, scalable architecture
* Developing APIs and backend services using .NET Core
* Designing and working with relational databases (Azure SQL)
* Collaborating in a small, high-impact team with a strong focus on delivery
* Contributing to technical decisions and improving how the platform evolves
Tech Stack
* React + TypeScript
* C# / .NET Core
* Azure (App Services, Storage, Identity)
* Azure SQL / MSSQL
* Entity Framework Core
What We’re Looking For
* 5+ years’ experience delivering production software
* Strong full stack experience across .NET and React
* Experience owning features end-to-end in SaaS or MVP environments
* Comfortable building both frontend applications and backend APIs
* Experience working in small, fast-moving teams
* Practical experience with Azure
* Strong sense of ownership and ability to work autonomously
This role is best suited to engineers who enjoy building products from the ground up, working across the stack, and shipping quickly in a collaborative environment.
Why Join
* Build new product, not maintain legacy systems
* Work across the full stack with real ownership of features
* Be part of a fast-growing SaaS platform already live in multiple markets
* Collaborate with experienced engineers in a high-autonomy environment
* Make a meaningful impact in healthcare and patient safety
