About the Role

For a large financial organisation, we are looking for a MuleSoft / Java Developer.

The project focuses on building and maintaining integrations between an Execution Management System and a Data Science platform. Real-time trading data is enriched with Bloomberg data and processed through Azure.

• Integrate real-time trading data with Bloomberg data.
• Configure and maintain Azure Event Hub connectivity.
• Ensure reliable two-way data flows between trading systems and Data Science algorithms.
• Troubleshoot and optimise integrations in a production environment.

Required Skills

• Strong experience with MuleSoft / Anypoint Platform
• Solid Java development experience
• Strong experience with Microsoft Azure
• REST APIs, RAML and JSON
• Experience with event-driven or real-time integrations
• Experience developing and deploying production-grade interfaces
• Strong analytical and problem-solving skills

Nice to Have

• Experience migrating integrations from MuleSoft to Azure
• Azure DevOps
• Bloomberg integrations
• Financial services or trading systems
• MongoDB / Linux
• OAuth
• Experience working with Data Science platforms

Who Will Thrive Here
Someone who can work independently in a complex integration environment, enjoys solving technical problems and understands the importance of reliability and performance when working with real-time financial data.
