The Opportunity

An established financial services business in the trading and markets space is hiring a C# Software Engineer to help build and evolve the core internal systems the company runs on.

This is a true full-stack Software Engineer role. You’ll work on long-standing, in-house C# / .NET applications, owning features end-to-end — from understanding requirements with the business to deploying production-ready software.

You’ll be joining a small, experienced team of Software Engineers, working across WPF desktop applications, ASP.NET web systems and SQL Server, with a strong focus on new development rather than maintenance-only work.

What You’ll Be Doing

Designing and building C# / .NET Framework software used across the business

Acting as a hands-on Software Engineer, owning work from idea to production

Developing across desktop (WPF), web (ASP.NET) and database (SQL Server)

Improving and refactoring existing C# systems for performance and maintainability

Working closely with other Software Engineers, testers and business stakeholders

What my client is looking For

Commercial experience as a Software Engineer working with C# and .NET Framework

Full-stack experience across UI, backend and database layers

WPF and ASP.NET experience (Web Forms and/or MVC)

Strong SQL Server skills (T-SQL, stored procedures, schema design)

Comfortable owning software delivery end-to-end in a small team

Why Join

• Real ownership, not ticket-chasing- You own features end-to-end: speak to users, design, build, ship, and see the impact. Small team means your decisions genuinely shape the systems.
• Interesting, business‑critical domain- Internal trading/broking systems used every day by front office and ops. Work that directly affects how money is made and risk is managed.
• Stable stack, long‑lived systems- Mature C#/.NET, WPF, ASP.NET, SQL Server – not constant rewrites / framework-of-the-week. Real engineering challenges in evolving 10‑year‑old systems without breaking the business.
• Variety of work- Mix of greenfield features, enhancements and some maintenance. Desktop, web and database – no narrow “just UI” or “just APIs” role.
• Small, senior team- Work closely with two experienced devs who know the systems inside-out. Short decision lines, direct access to the people who use what you build.
• Flexibility and trust- Remote‑first with sensible in‑person time for onboarding and collaboration. Measured on outcomes and reliability, not on clock‑watching.
• Impact and visibility- Users are internal, so feedback is fast and relationships are long-term. Easy to point at specific systems and say “I built that” or “I changed that
