Senior Product Designer — SuppCo

Company Overview SuppCo is on a mission to help people make sense of supplements and connect what they take to measurable outcomes in their bodies. Our platform helps users find high-quality products, optimize their stack, and understand what’s actually working — powered by our proprietary TrustScore quality rating system, our StackScore routine analysis algorithm, and SuppIQ, our AI companion for personalized guidance.

Earlier this year, SuppCo was acquired by Function Health, the membership platform that gives people a complete picture of their health through lab biomarker testing and clinician-backed insights. It’s a natural fit: Function shows you what’s happening inside your body, and SuppCo helps you act on it with confidence. The full SuppCo team has joined Function for the long haul, and together we’re building the most trusted health optimization experience anywhere — for millions of members.

This is a rare moment, as SuppCo and Function are launching a category-defining feature in late 2026 that will change how users use supplements forever. You’d be joining an experienced founder-led team with a track record of building and scaling category-defining products, now backed by Function’s reach, data, and membership base. The ambition is big, the runway is real, and the work matters.

Role Overview 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.

Key Responsibilities

• 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…
