National Grid is hiring a Lead UI Engineer for our Technology team. This role can be based at our Warwick, Bristol, or Cardiff offices, with hybrid working — and you’ll also have access to our London co‑working space if that location suits your working pattern.

You’ll foster a culture of continuous improvement, lean into Agile ways of working, and elevate engineering practice across the organisation.

You’ll also act as a trusted deputy to the Head of UI when needed, supporting wider engineering initiatives and playing an active role in mentoring, knowledge sharing, and strengthening our broader software engineering community.
