👤
Senior🎓
Top SchoolLéon McCarthy is a Principal Engineer and engineering manager based in Dublin with eight years of hands-on experience building full‑stack web applications, realtime data visualisations, and audio‑visual systems across medtech, eHealth, construction and experiential sectors. He blends developer, designer and researcher skills—backed by a PhD in Design & Communications and roles in academia—to lead service design, product innovation and user‑centred delivery including design sprints and lean UX. At Optum he progressed from senior full‑stack developer to Technical Lead and now Manager Principal Engineer, driving feature development and cross‑discipline collaboration. Léon’s work often surfaces at the intersection of realtime AI screens, data viz and interactive multimedia, and he brings an unusual combination of technical craft and facilitation expertise that accelerates stakeholder alignment. Outside work he’s an active outdoorsman—mountain biking, skiing, surfing and diving—which he says helps reset creative problem solving.
