Offer description

Full‑Stack Software Engineer (React & ASP.NET / C#)

We're looking for a Full‑Stack Software Engineer to join a growing development team building modern, business‑critical web applications. This role suits someone who enjoys working across the full stack and takes pride in owning features from initial concept through to deployment.

You'll be involved in both front‑end and back‑end development, working closely with other engineers, product owners, and stakeholders to deliver clean, scalable, and user‑focused solutions.

What you'll be doing

1. Designing and building front‑end web applications using React
2. Developing and maintaining back‑end services and web applications using ASP.NET and C#
3. Working across the full stack, contributing to both UI and API development
4. Building and consuming RESTful APIs
5. Writing clean, well‑structured, and maintainable code
6. Collaborating with the wider team to refine requirements and technical solutions
7. Troubleshooting issues, improving performance, and fixing bugs
8. Supporting the ongoing improvement of development standards, tooling, and ways of working
9. Taking ownership of features and delivering them end to end

What we're looking for

10. Strong commercial experience with React for front‑end development
11. Solid back‑end experience using ASP.NET and C#
12. Proven experience working in a full‑stack role (not purely front end or purely back end)
13. Good understanding of modern web application architecture
14. Experience building and working with APIs
15. Comfortable working in a collaborative, agile environment
16. Able to communicate clearly with both technical and non‑technical colleagues
17. A pragmatic approach to problem‑solving and delivery

Nice to have

18. Experience working with cloud environments
19. Exposure to CI/CD pipelines
20. Knowledge of modern testing practices
21. Experience working on scalable or high‑availability systems

Why consider this role?

22. Genuine full‑stack work with balanced exposure across front end and back end
23. Opportunity to work on real, production systems rather than greenfield demos only
24. A collaborative team environment with scope to influence technical decisions
25. Room to grow technically and professionally as the team and systems evolve

If you enjoy building complete web solutions and want a role where you can see the direct impact of your work, this is a strong opportunity to develop your full‑stack skillset further.
