Banking is changing. The software behind it needs to change too.
New regulation. Increasing use of AI. Greater scrutiny around security and governance.
That's why one of the world's largest investment banks has invested in growing several engineering teams, and we're looking for experienced Python Developers to help build the next generation of internal platforms.
This isn't about maintaining Legacy systems. You'll be joining projects focused on modernising how critical banking technology is built, tested and delivered.
You'll join one of several engineering teams responsible for developing applications that support:
- Global Markets Technology
- Regulatory Technology
- Front Office platforms
- Security and governance initiatives
- AI-enabled Proof of Concepts
Each team has a slightly different technical focus, giving opportunities to work on everything from high-performance applications to secure regulatory platforms.
We're really interested in yoiur ability to solve complex technical problems using your Python development experience within Financla Services/banking. applications
If you have exposure to Regulatory Technology, Trading or Front Office systems, Security engineering or GitHub Copilot or AI-assisted development, all the better!
You don't need to be an AI expert, but you should be interested in how it's changing software engineering.
You'll work on projects that directly support one of the world's leading investment banks, having exposure to cutting-edge regulatory and AI initiatives. These are genuine long-term investment hires rather than backfill hiring.
Hybrid working (3 days in London).
Salary: Up to £100,000 plus benefits.
