Introducing the GRC team
Trainline is investing in the next stage of our security programme, and we’re looking for a Security GRC Associate to help strengthen how we manage third-party security risk and assurance.

You’ll also support our wider governance and compliance programme, including ISO 27001 and our unified internal control framework. And you’ll help us rethink how GRC gets done, using automation and AI to cut manual effort and give the business a clearer view of risk.

Support ISO 27001 assurance work, such as control assessments, evidence gathering, audit preparation and remediation tracking, and help maintain our unified internal control framework
