Job description

About WON

WON is building the next generation of AI transformation for enterprise organizations. We are not another AI tools vendor. We build AI-native systems, combined with deep human judgment and category expertise, that fundamentally change how our clients operate, make decisions, and serve their customers.

Within that, our design practice works with premium DTC and ecommerce brands doing $50M to $500M+ in revenue: brands with strong products and strong followings that are still leaving growth on the table. We are not a “make it pretty” agency, and we are not another CRO shop running button tests. We combine deep behavioral insight with quantitative truth, then ship exceptional work fast, and we are building the AI-native systems that let us do it at a pace and scale traditional design teams cannot match.

AI powers our systems. Taste powers our design. The two compound each other: automation gives you the speed, and your judgment decides what is actually good.

This role reports to the VP of Design and works within the design roadmap they set.

What You’ll Own

• End-to-end execution of high-conversion experiences, full customer journey redesigns, and high-performance growth creative, scoped by the design roadmap and delivered in close collaboration with the VP of Design
• The WON design standard: clean, premium, behavior-driven, detail-obsessed, and fast to ship
• Adoption of WON's AI-native design systems, including Claude Design and Figma MCP, to move from concept to shippable work faster
• Automated asset creation built on our Figma component libraries, so variations and scale stop being manual work
• Contributing to the expansion of WON’s design agents and workflows, flagging what should be automated next

How Success Is Measured

• Conversion and AOV move measurably on the experiences you touch
• Customers move further through the funnel because of design decisions you made
• High-quality design ships fast, with less time lost between concept and production
• Component libraries and AI-assisted workflows reduce manual design work over time, not just for you but for the whole team
• Your work becomes the most reliable design output at WON, the standard new hires are measured against

Key Responsibilities

• Design high-conversion sites and landing pages that still feel premium, the kind that belong in the top 1%
• Design the full customer journey: acquisition landing flows, onboarding, collection architecture, PDP storytelling, cart and checkout, retention and member UX
• Design growth creative: paid social landing pages, advertorials, quiz flows, product education, bundles and upsell, offer frameworks that feel intentional, not desperate
• Build and maintain component libraries and design systems that scale across brands and campaigns
• Use Claude Design, Figma MCP, and automated asset generation to reduce production time without reducing quality
• Continuously evaluate your own workflow and flag what should be turned into a repeatable system or agent
• Present work with conviction, backed by session replays, cohort behavior, and voice of customer

Must-Have

• 5+ years in digital design, agency or in-house
• Strong ecommerce / DTC experience
• A portfolio of modern, premium work, not template-driven
• Mastery in Figma
• Strong typography instincts, real ones
• Taste that holds up under scrutiny: you can articulate why a design decision is right, not just that it feels right
• Comfortable being measured by impact, not just output
• Familiarity with AI design tools such as Claude Design or Figma MCP, or genuine interest in building them into your workflow

Nice-to-Have

• Designed for high-end brands (beauty, apparel, wellness, premium food)
• Experience working within Shopify ecosystems
• Built component libraries and design systems from scratch
• Contributed to CRO programs that produced measurable performance gains

We Value

• Modern, premium design work, not template-driven
• Evidence your design decisions moved a real metric: conversion, AOV, or funnel progression
• Systems thinking: component libraries and reusable frameworks, not just one-off screens
• Comfort presenting and defending design decisions with data

How We Work / Culture

• Design is treated as a growth system, not a decoration function
• Insights come first: every decision is grounded in customer behavior and tied to KPIs
• AI and automation are used to eliminate manual production work, not to replace judgment
• High clarity, ownership, and craft are core values: work ships fast instead of dying in Figma

Why Join WON

• Build design systems that move revenue for brands doing $50M to $500M+ in revenue
• Work at the intersection of design, behavioral insight, and AI-native workflows
• High ownership over execution, with a clear roadmap and a VP of Design invested in your growth
• Collaborate with a founder-led team with taste and urgency, and full access to the truth: session replays, cohort data, voice of customer
• Help build the AI design systems, including Claude Design, Figma MCP, and automated component workflows, that define how WON designs at scale

If you want to be a career designer, this probably isn’t for you. If you want to become an elite operator-designer who builds work that changes brands and makes numbers move, we’d love to meet you.
