About Tyndall

Tyndall National Institute is an international leader in semiconductors, photonics and deep‑tech research and innovation. As a leading collaborative European research institute, Tyndall is a key actor and hosting partner in the delivery of the ‘Chips for Europe Initiative’ (EU Chips Act).

Tyndall is Ireland’s leading research and innovation organisation and it is the national focal point for excellence in deep‑tech research, development and graduate training at the convergence of nanotechnology, microelectronics, photonics, electronics and AI. Tyndall is recognised as an international research leader in semiconductor, chip and digital technologies, particularly as applied to the fields of Information & Communications, Health & Life Sciences, Agritech & Food Security, Energy and Climate Mitigation, emerging fields such as quantum, and novel computing paradigms.

The Institute’s key objective is to see frontier research activities having a significant impact on economic development and societal challenges in Ireland, Europe and beyond. Central to Tyndall’s mission is delivering economic impact through research excellence in partnership with industry and academia. With an annual turnover of more than €50m, the Institute has a community of over 600 researchers, engineers, support staff, postgraduate students, interns and industry researchers-in-residence.

With significant committed Irish government support, Tyndall will grow to be 1,000 people by 2030, with approximately 750 researchers, including 250 PhD students. A new 17,000 m2 research building is under development adjacent to the Cork headquarters and there are developing plans to expand Tyndall’s existing Dublin research labs and to establish other research sites within Ireland.

Tyndall’s expansion is also supported by recent national and EU funding wins for significant (M€10’s) additional research equipment across a range of areas such as semiconductor processing, microscopy, quantum technologies, heterogeneous integration, ultra‑high speed optical communications and RF through THz characterisation.

About the Team

Photonics at Tyndall has a vibrant and expanding world‑class research ecosystem comprising more than 200 researchers with activities that include photonic theory, III‑V and III‑Nitride material epitaxy, photonic integration, hybrid integration and packaging together with applications in microelectronics, bio‑photonics and communication systems. Tyndall hosts the Research Ireland funded Irish Photonic Integration Centre (IPIC) a €30M initiative with 30 industry partners, including large multinationals, indigenous companies and start‑ups. Tyndall National Institute has a proactive entrepreneurial culture and we welcome applications from candidates who possess entrepreneurial and creative skills/experience, including the creation of technology start‑ups.
