The role is embedded in sprint teams alongside our Digital Tech Lead, internal colleagues, and our nearshore engineering partner. We offer a competitive benefits package including an annual bonus of up to 15%, pension contributions, 25 days annual leave plus flexible bank holidays and the option to purchase additional leave, discounts across our brands, wellbeing support, life assurance, free parking, an electric vehicle scheme, enhanced family-friendly policies, and more.
