What you will do

• Build and ship financial agents from prototypes to production at scale, owning their outcomes after launch.

• Design permissions, approvals, audit trails, and safe behavior for agents handling company money.
• Build offline evaluations and production monitoring that measure agent decisions and turn incidents into improvements.
• Develop chat, generative UI, and multi-channel interfaces for agent delivery.
