Job description

• SuppCo is looking for an exceptional individual contributor to take on our hardest product design work and set the standard for how design works here
• This is a hands‑on role and we mean it. You’ll design the most important surfaces in the product, and you’ll own the systems, patterns, and standards that all of our design work is built in
• We’re hiring the best product designer we can find — someone who also thinks in systems and can hold their own on strategy
• You’ll work in close partnership with our Senior Product Designer, a highly skilled designer with exceptional visual craft who owns significant surfaces of the product
• Together you are the design team. You’ll report to the Head of Product and partner with him daily on what we build and why
• Here’s what makes this job different from most senior design roles. Our engineering team is heavily AI-accelerated — Claude Code, Devin, Cursor — which means they can ship faster than any one designer can draw screens
• So your leverage is in the system: making it good enough that engineers ship on-brand and on-quality without design in the loop for every screen, which frees the two of you to spend your time on the hard, high‑stakes surfaces where craft and judgment decide the outcome
• If you’ve ever felt like the bottleneck on a fast team, this is the role where you get to fix that properly
• The work ahead is a mix of 0-to-1 and impactful optimizations. We’re building a new membership and commerce experience, connecting the SuppCo and Function Health products into one coherent journey, and going deeper on the daily habit that keeps people coming back. You’ll have a real influence on all three
• Design the product. Own end-to-end product design across SuppCo’s mobile and web experiences — problem framing, IA, flows, interaction, and polished, production-ready UI. You’ll take on the hardest and highest-stakes surfaces
• Own and scale our design system. We have a design system, but your job is to make it hold up and evolve. Mature the components, patterns, tokens, and documentation so that a fast-moving, AI-accelerated engineering team ships consistent, high-quality work without design reviewing every screen. Drive real impact, not just a nice Figma
• Optimize critical funnels and experiences. Push our most important flows to perform even better. From onboarding to activation and re‑engagement, you will help us relentlessly optimize the funnels that matter most
• Design the membership and commerce experience. Take on the surfaces where users discover products, understand value, and transact — the marquee initiative for the business over the next several quarters
• Connect SuppCo and Function. Improve the core flows that turn biomarker insight into supplement action and back again, so members move between the two products without seams
• Deepen the core experience. Improve the daily loop — stack management, scheduling, adherence, and AI‑guided discovery through SuppIQ — so more people build a routine that sticks
• Make the case for the work. Present design clearly and persuasively to the founders, the exec team, and the company: the problem, the options you considered, the tradeoffs you made, and what you expect to change as a result. Strong opinions, clearly argued
• Ground design in evidence. Use research, feedback, and product analytics to understand behavior, then define what success looks like for your work and follow through on whether it happened. We care more about measured impact than shipped volume
• Design AI‑native experiences. Shape how conversational and agentic surfaces feel — including SuppIQ and AI‑driven discovery — where the interface is part language, part UI, and the patterns are still being invented

Commerce, subscription, or transactional product experience. You’ve designed purchase paths, merchandising, or membership experiences and understand how design choices move conversion and retentionYou want to stay hands‑on. You’re at your best doing the work at the highest level, and you want your next role to deepen your craft and widen your influence rather than step away from the workYou can present.
