Responsibilities

• Design and develop scalable, high-performance internal platforms and applications for core business functions including Credit Trading, FX Hedging, Portfolio Monitoring, and Treasury.

• Collaborate cross-functionally with investment, operations, and data teams to translate complex business workflows into efficient, maintainable software solutions.
• Drive the full software development lifecycle - from technical design and implementation to testing, deployment, and production monitoring.

• Solid knowledge of relational databases and proficiency in SQL (e.g., MySQL).
• Practical experience in modern front-end technologies including TypeScript, React, and CSS.
• Experience architecting solutions using cloud infrastructure, particularly AWS.
• Competency with standard development and collaboration tools (e.g., Git, GitLab, CI/CD workflows).
• Excellent communication and stakeholder management skills; you’re comfortable discussing technical trade-offs with both engineers and non-technical colleagues.
• Bonus: A portfolio, GitHub profile, or examples of personal projects that showcase your technical abilities and creativity.

• Competitive bonus scheme.
• Bupa health & dental, Cycle to Work scheme, enhanced pension, and generous annual leave.
