Deloitte has appointed Stephen McMaster as a partner in Belfast. The news comes as Deloitte continues to build its operations in Northern Ireland.

Marie Doyle, office senior partner at Deloitte in Belfast, commented, “I’m so pleased to welcome Stephen into the partner group in Belfast and have no doubt he will continue to bring tremendous value to the firm in his new partner role. He has worked extensively on business critical, resilient and secure platforms for clients in a range of sectors and has unrivalled technical expertise.”

McMaster joined Deloitte 13 years ago as an enterprise architect following a 16-year career in technology and has led Deloitte’s engineering capability from Northern Ireland. In his current role he helps clients across public sector, financial services, and life sciences, design and build complex cloud platforms, with a particular focus on quality, security, and compliance – and he also functions as Deloitte’s chief technology officer for engineering in the UK. He is also cited by the Big Four firm as driving force behind Deloitte’s LGBTQ+ network PROUD in Northern Ireland

His promotion is the latest chapter in a long career – with McMaster said to have started coding at the age of eight. Throughout his software engineering career he has been heavily invested in nurturing junior talent in Northern Ireland, running several academies in conjunction with the Department for the Economy.

Speaking on the news, McMaster said , “I am extremely proud to become a partner in Deloitte and look forward to continuing to work with our fantastic clients to design and build technology platforms that help transform their operations.”

“I moved to Deloitte 13 years ago as an experienced hire in the analytics team and have been given the opportunity to grow and develop further in a number of platform engineering roles. I believe Northern Ireland is uniquely positioned for growth, given our highly skilled and motivated workforce, and I’m excited to help lead the growth of our local practice.”
