SDE III UI Engineer — Sizer / Flow Designer

Own UI features across both surfaces as a Solution Engineer moves from "describe the problem" to "here's the BOM" — from the flow topology editor through AI-assisted drafting to the Sizer's results.

• Build and improve the Flow Designer canvas: agent types, resource pools, and the flow topology editor.
• Build the UI for AI Copilot's draft-flow suggestions, including how a Solution Engineer reviews, edits, and accepts an AI-generated draft.
• Build Sizer's input UI for non-linear entry points — space, budget, throughput, or headcount as the starting constraint — and its BOM/results presentation.
• Work with the Map/Layout Designer and Applied AI teams on the handoff points between Flow Designer, AI Copilot, and Sizer.
• Fix and prevent regressions in flow-to-sizing conversion — the topology a user draws must map correctly into what Sizer consumes.

• 5-8 years building interactive, form-and-canvas-hybrid UI — Flow Designer is both, not purely one or the other.
• Strong React/TypeScript fundamentals.
• Experience building UI that incorporates AI-generated content as a starting point for user editing — accept/reject/modify patterns.
• Comfort working with a non-linear input model, where multiple valid starting points feed the same downstream calculation.

• Experience with flow-chart or diagramming UI libraries (React Flow, JointJS, or similar).
• Familiarity with warehouse automation, supply chain, or CPQ (configure-price-quote) tools.
