Job Description:

£700 p/day | Outside IR35 | Largely remote | 12-month contract

We are hiring a hands-on Senior Developer for a prestigious investment banking client, delivering tactical fixes and enhancements directly for front-office traders.

This role suits someone who thrives in a RAD/tactival environment: quick to understand a problem, comfortable with changing priorities and able to deliver practical, reliable solutions at pace.

The focus is on short development cycles, immediate business needs and improving existing trading tools, rather than a long-term strategic programme. Initial work will support Securities Lending, with opportunities to work across other trading desks.

What we’re looking for:

  • Strong development experience in C#, Python and Excel
  • Proven experience in front-office RAD or tactical development
  • A quick-thinking, pragmatic problem solver who can work independently
  • Confidence working directly with traders to understand issues and deliver solutions
  • Experience troubleshooting, supporting and enhancing existing applications
  • Ability to balance speed of delivery with testing and maintainable code

Useful additional experience:

Bloomberg API / BPIPE, C# WPF, SQL Server and Excel-based trading or risk tools.
