Lead Frontend Developer

Lead Front End Developers are responsible for building and maintaining a range of websites for our clients. We work with digital creatives to deliver responsive, web based projects ranging from content managed web sites, to SPAs such as finance calculators, configurators and ecommerce applications. At ITG, Lead Front End Developers work with a variety of tools and frameworks. Many of our projects use React, while others are based on vanilla JavaScript. We use modern tools, frameworks and IDEs, and work in agile sprint teams alongside business analysts, backend developers, QA testers and scrum masters.

Lead Developers are active members of the development team, specialising in Front End 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.
