Growth Designer — Paid Creative, Brand & Web UX (Remote Part-Time; backed by Y Combinator, $5M+ ARR, $23M+ raised)

About the role

Legion Health is building autonomous medical care (the AI doctor) starting with psychiatry, using an AI-native care-delivery platform that automates 95% of administrative work and has received regulatory authorization for AI to prescribe psychiatric medications. The company combines rich data, production AI, doctors in the loop, and end-to-end care operations to deliver better care to a clinically complex patient population, achieving flat ops costs, industry-leading NPS and retention, and tens of thousands of visits in two years. Backed by Y Combinator and leading VC firms, Legion aims for a 10X better patient and clinician experience.

As a part‑time Growth Designer, you will shape the path from first impression to patient conversion, combining paid‑creative strategy, visual and brand craft, and web UX. You will work closely with Consumer Growth, paid media, SEO, web implementation, and the founders, turning growth priorities into compelling creative concepts, high‑performing landing pages, and clear website flows that build trust and drive conversion.

Responsibilities

• Develop paid‑creative strategies, concepts, hooks, and visual directions for Meta, TikTok, and other growth channels.
• Design high‑quality ad variants, creator briefs, landing pages, and website experiences that connect the acquisition promise to the next step in the patient journey.
• Improve Legion’s visual brand across growth surfaces, including typography, layout, imagery, color, hierarchy, and trust signals.
• Map and simplify key website journeys so patients can quickly understand Legion, decide whether it is right for them, and convert with confidence.
• Turn campaign performance, user feedback, and growth priorities into clear design hypotheses and a steady cadence of experiments.
• Build reusable templates, components, and lightweight brand guidance that make future creative and landing‑page work faster and more consistent.
• Deliver implementation‑ready work in Figma (and, when useful, Framer or Webflow); collaborate closely with web and engineering partners through launch and iteration.
• Use AI tools throughout concepting, prototyping, production, and iteration to increase speed and creative range.

Qualifications

You’ll be successful if you:

• Create a coherent, visually excellent journey from ad to landing page to website.
• Ship a steady cadence of strong creative and web experiments with explicit hypotheses and useful learning.
• Improve the clarity, trust, and conversion performance of the growth surfaces you own.
• Give the team reusable design systems and templates that increase speed without lowering quality.
• Operate independently, communicate clearly, and reliably turn ambiguous priorities into finished work.

Ideal background and skills:

• A strong portfolio that includes beautiful homepages or landing pages, intuitive web flows, and brand or growth creative, showing personal contribution and results.
• Exceptional visual craft across typography, layout, hierarchy, imagery, and brand systems, paired with sound UX judgment.
• Experience turning an audience insight or growth brief into multiple creative concepts and testable variants.
• Fluency in Figma; experience with Framer, Webflow, motion, creator or UGC briefs, or direct‑response creative is helpful.
• Comfort using qualitative feedback and quantitative performance data to improve work without reducing every design decision to a single metric.
• Demonstrated use of AI‑native creative and design tools to materially improve speed, range, or quality of real work.
• Clear writing, low ego, high ownership, and strong asynchronous collaboration.
• Experience in health care or another trust‑sensitive consumer category is helpful.
• Strong judgment and exceptional work matter most.

Pay

Hourly rate: $50–$125 per hour, based on portfolio quality, relevant experience, speed, and scope.
