Working Arrangements and Team Expectations

This role sits within the Information Security Platform Engineering function and shares a common operating model with the wider team. Engineers own the security platforms they build end to end: design, deployment, day-to-day operation, tuning, and lifecycle management. Work is delivered against agreed service levels and measured on control coverage, platform availability, and the quality of detection and prevention outcomes. Because the teams are distributed across LATAM, EMEA, and North America, all roles require reliable overlap with United States business hours and fluent written and spoken English.

• Operate assigned security platforms as a service, including capacity planning, patching, upgrades, health monitoring, and vendor case management.
• Automate repetitive configuration and operational tasks, and treat platform configuration as code wherever the tooling supports it.
• Support incident response and forensic investigations with platform expertise, evidence, and rapid containment actions.
• Maintain runbooks, architecture diagrams, and control documentation to a standard that satisfies internal audit and external assessment.
• Participate in an on-call rotation and in scheduled change windows, including occasional work outside standard business hours.

What we offer:

• Hybrid working model (2 days in the office and 3 days working remotely)
• Stable employment with an employment contract, private medical care, and a benefits package including MultiSport and a benefits platform
• Opportunity to work in an international environment and collaborate with experienced Grant Thornton experts and professionals from around the world
