From the original posting

Fin, now part of Salesforce, is on a mission to help businesses provide perfect customer experiences.

What's the opportunity?

Fin is transforming customer service through AI, helping businesses deliver fast, accurate, and reliable support at scale. Trust is foundational to that mission.

Fin's Security Engineering team is unlike most security teams. We own and operate critical security services, build customer-facing security features, and partner with engineering teams to make secure development the default. We're engineers first; designing, building, and operating systems that protect Fin and its customers. The team owns and operates tier-zero services including authentication, SAML/SSO, teammate activity logs, malicious URL scanning, and other critical trust and security capabilities.

The mission of the team is to help Fin build and operate trusted AI-powered customer service experiences by making security a natural part of how products are designed, developed, and delivered. As Fin continues to expand its capabilities and adoption, you'll help shape how security evolves alongside some of the most ambitious AI-powered products in customer service. We're taking an AI-first approach to security, exploring areas such as AI-powered detection, red-team automation, continuous monitoring, and emerging defensive capabilities to help meet an evolving threat landscape.
