We are looking for a Junior C# .NET Developer to join a growing technology team responsible for building and supporting high-performance, real-time software used within trading.
This is an ideal opportunity for a graduate or early-career developer who has already gained some commercial C# experience and now wants to take a significant step forward technically.
You'll work alongside experienced software engineers, gaining hands-on exposure to trading systems, real-time applications, high-performance software and complex technical challenges that you wouldn't typically encounter in a standard junior development role.
You'll be encouraged to learn, ask questions and gradually take on more responsibility as your technical skills develop.
What You'll Be Doing
Develop and enhance applications using C# and modern .NET
Work on real-time, performance-critical trading technology
Learn directly from experienced senior software engineers
Build new features and improve existing systems
Write clean, maintainable and well-tested code
Work with SQL and relational databases
Investigate technical issues and learn how to troubleshoot production systems
Participate in code reviews, testing and debugging
Gain exposure to performance optimisation, scalability and system reliability
Work across the full software development lifecycle
Develop your understanding of professional software engineering best practices
What We're Looking For
A strong academic background with at least a 2:1 degree in a STEM subject
Some commercial experience developing software with C#
Good understanding of .NET / .NET Core
Solid knowledge of object-oriented programming
Understanding of SQL and relational databases
Strong problem-solving and analytical skills
A genuine enthusiasm for software engineering and learning new technologies
Someone who wants to understand how and why systems work, rather than simply writing code
Good communication skills and the ability to learn from experienced developers
Great If You Have
You don't need to tick every box, but exposure to any of the following would be beneficial:
ASP.NET Core / Web APIs
SQL Server
Multithreading or asynchronous programming
Git
Automated testing and CI/CD
Distributed systems
Performance optimisation or low-latency applications
AWS or Azure
An interest in financial markets, trading or quantitative technology
Why This Is a Great Junior Opportunity
This isn't a role where you'll spend your first few years working on basic development tasks.
You'll be joining an environment where software performance, speed, reliability and quality really matter, giving you the opportunity to develop skills that can take years to gain elsewhere.
You'll learn from experienced engineers, gain exposure to sophisticated trading technology and build a strong foundation across C#, .NET, databases, real-time systems and high-performance software engineering.
For a Junior Developer who is technically curious, ambitious and keen to learn, this is an opportunity to develop quickly and build a genuinely strong engineering career within trading technology.
