Operational Team, Advisory board, Strategic Leadership Team
Brings thirty years of client-side capital programme experience to the CJK boardroom — challenging the business on what tender evaluators and project sponsors actually need to see.
Eilish joined CJK’s Advisory Board in 2023, after a career spent almost entirely on the client side of complex M&E delivery. She spent the first part of her career in capital programme leadership for one of Europe’s largest pharmaceutical manufacturers, planning and delivering new-build and major upgrade facilities across Ireland, the UK and Belgium.
Over that period she commissioned and oversaw projects ranging from sterile fill-finish lines to greenfield API plants — and worked closely with, and rigorously evaluated, the leading M&E contractors operating across the region.
After leaving the pharmaceutical sector, Eilish moved into independent advisory work, supporting infrastructure-heavy businesses through scaling, governance and capital programme strategy. She holds non-executive positions with two organisations in the data centre and built environment sectors alongside her role at CJK.
It’s the variety that keeps me. Different sector, different scale, different team. You don’t get stuck doing the same thing for a decade
