Role: Expert .NET Developer – Cross Asset Trading System
Location: Very Flexible. Can offer Remote with occasional travel to London City offices
Contract: 12 months
Rate: Up to £700/day
About the Role:
We are partnering with a leading investment bank on an ambitious programme to modernise and enhance their cross-asset trading systems. This is a technically challenging, hands-on role, ideal for an expert .NET developer with a strong SQL Server background and experience working in financial environments.
You will be joining a highly skilled team focused on performance, reliability, and scalability, tackling complex issues in real-time, data-driven applications. This is purely a tech-heavy role—business knowledge is helpful but not required.
What You’ll Be Doing:
- Leading initiatives on DB modernisation and performance optimisation
- Archiving legacy data from key tables with precision to ensure smooth migrations
- Redesigning and refactoring high-activity tables to improve performance and maintainability
- Developing frameworks and tooling for real-time monitoring of trading systems
- Modernising and upgrading legacy codebases, driving best practices in .NET development
What We’re Looking For:
- Expert .NET Developer: Deep knowledge of .NET 8 and .NET 4.8
- SQL Server Proficiency: Strong fundamentals in querying, table design, and ETL processing large datasets (performance tuning not required)
- ADO.Net Expertise: Familiarity with EntityFramework or other ORMs is a plus, but not essential
- Async & Multithreading Mastery: Experience in low-latency, data-driven applications
- Attention to Detail: Ability to spot rare, critical issues before they reach production
- Previous experience in the finance industry, ideally in trading systems
Why This Role Is Exciting:
- Work remotely while tackling cutting-edge technical challenges
- Collaborate with a high-performing team on a strategic, high-impact programme
- Influence system design, architecture, and long-term performance improvements
- Competitive daily rates up to £700
If you’re a highly skilled .NET developer who thrives in challenging, high-stakes environments and loves working with complex, real-time systems, this is the perfect opportunity to make an impact.
