Our client, an established financial services company, is looking for a capable Senior Java Developer to strengthen their engineering function. You’ll take a hands-on role in shaping the future of their post-trade platform, spanning proprietary systems, APIs, client-facing reporting and a web portal, alongside tailoring an existing third-party trading system. What’s in it for you:

• Salary up to £90,000

• On the development side, you’ll build and support in-house systems, APIs, reporting tools and the client portal; bring AI into the development lifecycle; adapt third-party trading systems as the business requires; and write clean, thoroughly tested code grounded in SOLID principles, Design Patterns and Clean Code.

• On the people and communication side, you’ll work with Client Services and Product Management to shape solutions from business requirements, explain technical concepts clearly to audiences ranging from developers to senior non-technical stakeholders, and cut through complex problems to find root causes and prioritise fixes.
