Introducing the Trainline Security Team 👋
As part of Trainline’s Information Security (InfoSec) team, the Identity and Access Management (IAM) Engineer is responsible for designing, implementing, and managing robust IAM solutions that protect our systems, users, and data. This role plays a key part in reducing security risk by ensuring that access to infrastructure, applications, and data is governed by principle-of-least-privilege, role-based access, and strong authentication controls.
The IAM Engineer works closely with security, infrastructure, and engineering teams to enforce security policies, enable operational efficiency, and maintain compliance with regulatory and industry standards. Operating in a fast-paced digital environment, the role supports Trainline’s security posture by ensuring only authorised users have timely and appropriate access to critical resources—helping to safeguard both customer trust and business resilience.
