This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Software Engineer, Identity in Ireland.

This role places you at the core of building secure, scalable identity systems that power modern digital platforms. You will design and maintain authentication and authorization infrastructure used by a large global developer base, ensuring every interaction remains secure and reliable. Working in a distributed, high-scale environment, you’ll tackle complex challenges across OAuth, SSO, and token-based systems. As AI-driven workflows evolve, you’ll help define how non-human actors securely interact with platforms. The position offers a strong mix of backend engineering, system design, and cross-functional collaboration. You’ll contribute to shaping next-generation identity models in a forward-thinking, remote-first environment that values autonomy and technical excellence.
