• Support and optimise CI/CD pipelines (e.g., TFS Build, Azure DevOps)
• Troubleshoot and resolve production issues in a low-latency trading environment

Required Experience:

• Strong development experience in C# and .NET Core/.NET Framework
• Hands-on experience integrating FIX protocols (e.g., QuickFIX/n, OnixS)
• Proficiency with message brokers (RabbitMQ, Kafka, MSMQ, etc.)
• Knowledge of STP, order lifecycle, and post-trade processing
• Familiarity with CI/CD tools like TFS Build, TeamCity, or Azure DevOps
• Solid understanding of trading and risk systems in capital markets

Desirable:

• Background in equities or FX trading environments
• Exposure to microservices architecture and distributed systems
• Experience with SQL Server and database-driven workflows
• Agile delivery experience and comfort working in fast-paced, regulated environments

This is a great opportunity to work at the heart of a high-performing trading business, using modern .NET technologies to build and support systems critical to front-to-back trade execution and processing.
