Job description

Healthspan is the world's leading digital longevity clinic. We help forward-leaning people add healthy years to their lives using the same evidence that's shaping the field — not the version that's been flattened into a supplement ad.

We're hiring the person who will get that work in front of the people who need it. Not a marketing lead in the traditional sense. The role we're describing doesn't have a settled title yet, so here's the honest version of what it is.

The role

Most health companies hire a Head of Growth, hand them a budget, and wait for decks. We're not doing that.

We're looking for one person who treats distribution as an engineering problem. Someone who builds the systems that find, inform, and convert the right patients — then iterates on those systems faster than any team of ten could.

This is an individual contributor role. No team underneath you. No layer to delegate to. The expectation is that you ship the work yourself, end to end, because the leverage in 2026 comes from your stack, not your headcount.

You’ll own company revenue alongside the CEO. Not the marketing funnel, not the acquisition number — the top line. You’re not executing a plan someone else wrote. You’re the person who wakes up thinking about where the next patient comes from, and who builds the machinery to get there.

Ads, landing pages, SEO, email, social, paid search, ASO, lifecycle — all of it runs through infrastructure you build. Agents, pipelines, MCP servers, custom tooling. You write the briefs and the code. You ship the creative and the attribution model.

This is a zero-to-one build. On day one, you own the full funnel.

What you’ll actually do

• Own revenue with the CEO. Forecast it, defend it, grow it. Every decision ladders to that number.
• Ship end to end without being blocked. You write the copy, build the landing page, wire the analytics, configure the ad account, generate the creative, push it live. If a piece of the stack is missing, you build it. The whole point of this role is that nothing waits on someone else.
• Hunt for new channels and experiments without being asked. If a surface exists where our patients spend attention, you’ve already tested it or have a reason you haven’t. The roadmap is something you write, not something you’re handed.
• Think past the job description. Build systems and strategies nobody asked for because you saw the opening — partnerships, distribution plays, product‑adjacent growth loops, referral mechanics, new acquisition surfaces that don’t exist yet. Operate like a founder whose name is on the cap table.
• Stand up the acquisition engine across paid, organic, and lifecycle. Ship landing pages, creative, and funnels at a pace that would require a department under the old model.
• Build the internal tooling that makes that pace possible — creative generation pipelines, ad‑ops agents, performance dashboards wired directly to live data, self‑evolving experiment logs.
• Own the content engine. Translate clinical protocols and peer‑reviewed research into content that reads like signal in a feed full of noise.
• Run the numbers honestly. Attribution, cohort economics, LTV by protocol. The goal is truth, not a better‑looking dashboard.

Who this is for

You’ve probably been underemployed by the conventional structure of a marketing team. You build things.

You’re technical. Comfortable in a terminal. Fluent with Claude Code, Cursor, the Meta and Google APIs, MCP servers, and whatever dropped last month. You’ve shipped agents that do real work, not demos. You can read and write code well enough that “I’ll just build it” is your default response to a missing tool. We don’t need a senior engineer — we need someone who can move through the full stack of growth without the hand‑off tax.

You can do the whole thing yourself. Strategy, creative, copy, design, code, paid ops, analytics, content. Not at world‑class depth in every domain — but with enough range that you don’t get blocked waiting on a designer, an engineer, an ops person, or an agency. The work compounds because nothing leaves your hands until it’s shipped.

You’ve done it somewhere visible. You can point to a company where you ran growth — or a major piece of it — and show the numbers. CAC down, conversion up, a channel you opened, a system you built that’s still running. We’re not interested in theory or thread takes. Show the work and the results, at a real company, with real spend or real users.

You understand that distribution in 2026 is systems engineering applied to human attention. You’ve read the Anthropic growth team’s playbook — one operator, agent swarm, 10x creative output — and your first thought was I could go further than that.

You can also write. Not prompt‑write — actually write. Healthspan’s voice is plainspoken, intellectually confident, allergic to hype. If you can’t carry that tone yourself, you can’t direct the system that produces it at scale.

You care about longevity science, or you care enough to get rigorous about it quickly. This is health. The work has to be right before it’s fast.

Who this isn’t for

• People who run campaigns but don’t build
• People who build but can’t write
• Anyone whose best work lives inside a Notion board of OKRs
• Anyone who needs a team under them before they can produce output
• Anyone who waits to be told what to test next
• Anyone whose growth experience is theoretical, agency‑side, or unverifiable

What we offer

• Direct ownership of the growth function at a category‑defining clinic
• Equity commensurate with the scope
• A clinical and product team that respects the craft and will give you room to run
• Compensation that reflects the fact that one person doing this well is worth more than a department doing it the old way

To apply

Send us something you’ve built and the results it produced. Not a resume summary — the actual thing. An agent, a pipeline, a creative system, a paid campaign with the numbers attached. If the work is proprietary, describe it in enough detail that we can tell whether you did it. Name the company. Name the metric.

One link. One paragraph on what it does and what it moved.
