Three Ireland appoints Chief Technology & Innovation Officer and Head of Corporate Affairs
11 May, 2026: Three Ireland has today announced two senior leadership appointments, with Jon Davies named Chief Technology & Innovation Officer and Sinéad O’Donnell appointed Head of Corporate Affairs, as the company continues to invest in its technology, innovation and corporate leadership capabilities.
As Chief Technology & Innovation Officer, Jon Davies will have responsibility for Three Ireland’s network, technology architecture and innovation agenda. His remit includes driving network excellence, advancing 5G and AI-enabled innovation, and ensuring technology investment delivers tangible improvements to customer experience while enabling colleagues across the business.
Jon brings more than 20 years of senior technology leadership experience across large-scale telecommunications and digital transformation programmes in Ireland and the UK. Formerly Director of Digital & Innovation at Three UK and Director of Digital & Transformation at Vodafone UK, he has led multi-million-pound P&Ls and delivered board-level transformation initiatives, modernising platforms and embedding agile and AI-driven operating models. He has also held senior roles at Adobe, Orange and Eurostar.
Speaking about his new role with Three Ireland, Mr. Davies said, “I’m delighted to join the Three leadership team in Ireland at such a pivotal time for the business. Technology and innovation are transforming how customers connect and interact every day, and I look forward to working with colleagues to continue strengthening Three’s network, platforms and innovative offerings for the future.”
As Head of Corporate Affairs, Sinead will lead the company’s corporate communications, public affairs, business PR, press office and corporate social responsibility strategy. She will play a key role in shaping and enhancing Three’s corporate reputation, while supporting the Executive Leadership Team on strategic communications and stakeholder engagement.
Sinéad brings over 20 years’ experience spanning journalism, agency and corporate communications. Prior to joining Three Ireland, she was Associate Director in the Corporate and Public Affairs practice at Wilson Hartnell (Ogilvy), where she led integrated communications strategies for a range of leading national and global organisations across highly regulated sectors.
She began her career as a journalist with organisations including Newstalk and Virgin Media Television, an experience that gave her strong news judgement, a deep understanding of the media landscape and an ability to anticipate how stories develop from a newsroom perspective. She later built on this media experience in senior agency and corporate communications roles, where she developed deep expertise in reputation management, issues and crisis communications, and leading high‑performing press office functions.
Speaking about her new role with Three Ireland, Ms. O’Donnell said, “I am delighted to join Three Ireland at such an important point in its evolution. Three plays a vital role in Ireland’s connectivity and innovation landscape, and I look forward to working with colleagues and stakeholders to further strengthen trust, reputation and engagement across the business.”
These appointments reflect Three Ireland’s continued focus on strengthening its leadership across technology, innovation and corporate affairs as the company advances its long-term growth ambitions in the Irish market.
