An opportunity to play your part – As an IS Portfolio Delivery Manager at Centrica, you’ll sit right at the heart of where strategy meets delivery. You’ll be responsible for managing and successfully delivering a diverse portfolio of Agile and Waterfall initiatives, each with clear outcomes that directly support a specific business area.
