Senior Content Designer

Company Overview Function Health is the AI operating system for health, designed to empower people to live 100 healthy years. We are redefining how individuals understand, measure, and improve their health by moving beyond the limitations of traditional care and enabling comprehensive, continuous insight into human biology. Function has been recognized as one of Fast Company's Most Innovative Companies of 2024, and is venture-backed by Redpoint and other leading venture firms. Over half a million members have joined Function to take control of their health. Through comprehensive lab testing, MRI and CT imaging, longitudinal data, and guidance from AI and clinical teams, Function gives members a complete and continuous view of their health - and the clarity to act on it. Through acquisitions across imaging, mobile phlebotomy, and supplement tracking and optimization, Function is building an integrated health platform that spans the full path from testing to health clarity to daily action. Function recently announced a $298M Series B and is entering its next chapter of growth. As we scale, the quality and durability of our People systems, data, and insights will directly shape our ability to attract, retain, and support exceptional talent. We are growing our team and seeking out world-class talent that deeply believes in our mission to positively impact global health, has a relentless bias toward action, and a growth mindset. Function fosters a collaborative and dynamic environment where every day we build the future. Role We're seeking a Senior Content Designer to own the voice of Function across product and member communication-a sharp thinker who understands that great copy doesn't fill space, it earns trust. This isn't a role for someone who steps in after the UX decisions are made. You're in the room where those decisions happen, shaping how Function thinks, speaks, and connects at every touchpoint. You'll collaborate closely with Product Design and PMM teams to ensure that every piece of copy feels simple and supportive, and deliver high-quality work in a fast-paced environment. You write with clarity and conviction and know the difference between copy that explains and copy that moves. You can hold the brand voice at scale while tuning to context-a lab result summary reads differently than an onboarding moment, which reads differently than a paywall. You hold all of it with coherence. AI is a new content material, and we treat it that way. This role requires someone who has already internalized that shift. If you thrive in a fast-paced, high-growth environment and are deeply motivated by Function's mission-we'd love to meet you. Key Responsibilities Product copy across all touchpoints including in-app flows, onboarding, member communications, notifications, action plans, empty states, error handling, and more Brand voice stewardship: define, evolve, and defend Function's voice across surfaces and contributors Cross-functional collaboration with Design, Product, and Clinical to ensure copy is accurate, human, and on-brand. Always flagging inconsistencies, and raising copy-related edge cases early in the process UX writing upstream of design decisions. You'll shape the full experience Data-informed iteration such as A/B testing, member feedback, and performance data as tools for continuous improvement Editorial review: You'll raise the standard of copy org-wide, not just your own output Qualifications/Skills 5+ years of UX writing or product copywriting experience, ideally in a consumer health, wellness, or complex-product context with a portfolio that demonstrates range Fluency across copy types with a consistent quality across all of them: in-product flows, email, campaign headlines, onboarding, error states Strong instinct for voice and tone calibration. You can write warmly and precisely for a member reading a sensitive health result, and sharply for a conversion moment, knowing which is which Experience in health, wellness, or clinical tech is a meaningful differentiator: comfort with medical terminology, regulatory constraints, and high-stakes information hierarchies Collaborative by default. You work closely with designers, PMs, and clinicians, and make the work better through that friction Comfort working directly in Figma, managing your own workload across multiple concurrent projects, and writing copy that doesn't need a lot of hand-holding to land. You have an AI-native mindset, understanding how LLMs generate language, where they produce noise, and how to work with and around them deliberately You use AI tooling actively. Claude, Cursor, or equivalent - to accelerate ideation, draft generation, and iteration without sacrificing voice quality You can design content for agentic experiences. You've thought carefully about how a product communicates when the system is doing the work, not just responding to a prompt You think critically about AI-generated copy: you know when it's useful scaffolding and when it's eroding the voice, and can act accordingly *Please share a portfolio of work in order to be considered To be a strong fit, you embody our Core Values Ruthless Prioritization: We don't let perfect get in the way of progress.
