Lead Java Developer

Job Description

ITG require a talented Lead Java Developer to work on the development of a range of web based products and tools.

Lead Java Developers are responsible for building and maintaining a range of websites and applications for our clients, ranging from content management systems, to complex rules engines, finance calculators and tools.

At ITG, Lead Java Developers work with a variety of tools and frameworks. Many of our projects use Spring Boot, while others are based on light weight servlets and serverless, cloud functions. We use modern tools, frameworks and IDEs, and work in agile sprint teams alongside business analysts, frontend developers, QA testers and scrum masters.

Lead Developers are active members of the development team, specialising in Java Development but also working on projects using technologies with which they may be unfamiliar.

We integrate AI tooling across the full development lifecycle — from business analysis and architecture through to design, QA, and code delivery. Lead Frontend Developers use AI coding assistants (primarily Cursor) as a core part of daily workflow, not as an optional extra. It is important that developers understand how to use AI effectively and where its limitations lie.

Lead Developers lead from a technology standpoint, but also support, mentor and develop other members of the team.
