Job Summary

Own the growth engine from strategy to execution across paid media, asset creation, testing loops, funnel ownership, measurement, safety, and team shaping.

  • Lead end-to-end acquisition strategy, channels, budget, and KPI ownership.
  • Run the paid media and creative development with hands-on experimentation and optimization.

Job Description

Responsibilities

  • Own acquisition end to end. Set the growth strategy, choose the channels, manage the budget, and be accountable for leads, conversion to treatment, and cost per family acquired.
  • Run paid media yourself. Build, launch, and optimise campaigns on Meta first, then test TikTok, Google, and whatever else earns a place. You're comfortable in the ad platforms daily, not reading reports from someone else.
  • Produce assets yourself with AI tools, Figma, CapCut, and similar, and brief creators when that's the better route.
  • Run a disciplined experiment loop. Form a hypothesis, set up a clean test, say in advance what would prove you wrong, read the result honestly, and iterate. Build the system around it: testing cadence, angle library, naming conventions, and a bank of real parent and young-person language.
  • Own the full funnel. Landing pages, lead capture, nurture sequences, and the handover to our clinical intake team. Find where families drop off and fix it.
  • Build the measurement foundations. Tracking, attribution, and a simple dashboard that tells us weekly what's working, what it costs, and where the next pound should go.
  • Make growth safe as well as effective. Work within safe-messaging guidelines for self-harm and suicide, platform health advertising policies, and the ASA/CAP code, with sign-off from our clinical team. You treat these as design constraints to be creative within, not blockers.
  • Shape the growth team. As the engine proves out, help decide what to hire, build, or outsource next.

Requirements

  • 5+ years in consumer growth or performance marketing, with a track record of owning results (not just contributing to them), ideally at an early-stage company.
  • You've managed paid budgets yourself and can talk fluently about CAC, conversion rates, payback, and attribution.
  • You're genuinely strong on creatives. You've written performance copy with results you can point to, you have taste, and you make assets yourself rather than only briefing them.
  • Your background is consumer-facing, ideally in health, wellbeing, parenting, or other high-trust purchases. If your experience is mainly B2B SaaS, this probably isn't the role.
  • You're comfortable being the only person doing this, with ambiguity, a lean budget, and a very driven team.
  • You understand that when the audience is vulnerable, "what converts" and "what's right" both matter, and you can hold both.
  • You want to work on youth mental health for a reason you can say out loud.

Preferred

  • Experience marketing in a regulated category (health, pharma).
  • You've built lifecycle or CRM journeys (email, SMS, WhatsApp) that moved conversion.
  • You've run a creator or UGC pipeline, including sourcing, briefing, and quality control.
  • Some exposure to partnership or channel growth, such as schools, charities, employers, or insurers.
