Senior Security Engineer: Threat Detection & Incident Response

LemFi in Dublin is seeking a Senior Security Engineer to own how we protect our people and products from the inside. You will build controls, write detections and run incidents, reporting directly to the CTO.

It's a small team, so you'll shape the playbook and own security outcomes across endpoints, identities and internal tools. You'll drive threat detection, incident response and intelligence-driven controls, with a bias toward automation, AI and ML to sharpen detections.
