Design and build a Banking frontend SDK - hooks and UI components - packaged for external integration, with documentation and framework integrations. Shape the shared component library and a micro-frontend approach that keep product surfaces consistent. Define frontend coding and component standards across the platform. Own the frontend observability and test-automation bar so regressions are caught before customers feel

You're the connective tissue across the entire billing lifecycle - the person every other function turns to when something needs to actually get resolved, not just flagged. That means owning billing file validation before release, payment and check reconciliation, credits and refunds end to end process; being the Finance point of contact for all US based teams who they can rely on for any customer-impacting billing issue.

The problem space The loop we care about: production traces become data, data becomes training and evaluation, and better agents produce better traces. Projects live somewhere on that loop. Harness and inference-time work. Context engineering, tool and skill design, orchestration, and deciding where extra inference compute actually pays. Self-improvement loops run behind hard fences. Post-training for agents. SFT on curated trajectories, preference optimization, RL on real agent tasks. Reward design where outcomes are verifiable, process vs. outcome supervision, distilling frontier behavior into cheaper models. Environments and rewards. Turning enterprise workflows into training
