Proton is building an AI operating system for wholesale distribution, unifying CRM, PIM, eCommerce AI, and Order & Quote Entry into a single platform. The company serves hundreds of distributors from family-owned shops to publicly-traded enterprises, backed by Felicis Ventures and Battery Ventures.
As UI Product Designer, you'll own how Proton looks and works, reporting to the VP of Product. You'll ship in cross-functional squads with PMs and engineers, spending significant time with customers—watching distribution reps use your designs in real warehouses and sales floors. Your users sit in one screen for eight hours daily and have tolerated legacy software for years; your job is to create something they'd choose: fast, modern, and a pleasure to use.
This role differs from standard product design in two critical ways. First, you're an AI-native designer, not just a Figma operator. You'll prototype concepts in real code using Claude Code and similar agentic tools as first-class collaborators, iterating with heavy AI leverage while making the calls AI cannot. Second, you set the craft bar for the entire company. Distribution software is notoriously grim; you'll own the visual language and design system across all four products, deciding how AI surfaces suggestions, confidence signals, review flows, undo, and agent handoffs—patterns the industry hasn't yet settled.
Key responsibilities include prototyping in code to validate interactions before commitment, owning the design system (components, tokens, documentation, and adoption across squads), defining what AI-native UI patterns look like in practice, working within an agentic scrum model where cadence follows what teams and agents can ship, and conducting constant customer research onsite in warehouses and on sales floors.
You'll need demonstrable craft in typography, layout, color, hierarchy, and iconography—work that looks intentional, not assembled. You must have shipped real products with real users, owning end-to-end delivery alongside PMs and engineers. Daily hands-on use of AI tools (Claude Code, Cursor) to ship work, not generate comps, is essential. Your portfolio should showcase workflow reimaginations where you decided what to keep, throw out, and how to drive adoption. You think in systems—authoring one beautiful screen while writing rules that let others create fifty consistent ones. You understand traditional scrum and can help rebuild it as agentic scrum. You're pulled toward customers and prefer being in the room with users over research summaries.
