Department/Project Description

An enterprise technology group is building a dedicated security validation team focused on vulnerability assessment and security testing across the group's products and systems. The team runs structured testing campaigns: penetration testing, vulnerability discovery and triage, secure code review, and building automated test suites to make the process repeatable at scale.

The team also gets early access to specialized AI models and evaluates how they can accelerate security testing - an area we're actively investing in, though the core of the work remains hands-on security engineering. Scope covers internal systems as well as business-unit products across the group, agreed campaign by campaign. The team starts small and scales into a permanent capability.
