Essential

  • Expert-level development experience in C# / .NET
  • Strong experience with SQL Server
  • Proven experience working with service-based architectures (REST, gRPC, web technologies)
  • Solid understanding of asynchronous programming and multithreading
  • Experience with messaging middleware (e.g., IBM MQ or similar)
  • Experience working with front office, trading, or risk stakeholders
  • Strong software engineering fundamentals with a focus on performance and scalability

Desirable

  • Knowledge of financial markets and instruments, particularly commodities or derivatives
  • Experience with pricing and risk systems
  • Exposure to electronic trading platforms
  • Experience across asset classes (e.g., FX, Equities, Fixed Income, Commodities)
  • Familiarity with tools such as:
  • Consul
  • Redis
  • Octopus Deploy
  • TeamCity


Competencies

  • Strong organisational skills and delivery focus
  • High attention to detail and quality
  • Ability to work independently with minimal supervision
  • Comfortable working in fast-paced, high-pressure environments
  • Excellent communication and stakeholder management skills
  • Proactive mindset with a strong work ethic
