[Hiring] Senior Media Buyer @AIOS (YC W20/S21)

Role Description

As Senior Media Buyer at AIOS, your mission is to drive elite Meta performance as we scale paid acquisition across the UK and new international markets.

• Meta is our largest and most important paid channel, currently spending £2.5M+/month.
• Your job is to help us scale that spend profitably, maintaining control of CAC, creative learnings, reporting discipline, and market execution.
• You’ll work directly with our Head of Performance, Dave, to ramp into the accounts: campaign structure, creative library, compliance constraints, reporting cadence, and market behavior.
• Day to day responsibilities include:
  • Planning spend and structuring campaigns.
  • Optimizing toward profit-aware ROAS/CAC targets.
  • Translating performance signals into clear creative briefs.
  • Running a structured operating cadence for trust and clarity.
• This is a hands-on role inside Meta, with potential to expand into adjacent channels like Google, TikTok, YouTube, and programmatic.

Qualifications

• Proven scale on Meta: personally operated Meta accounts at £1M+/month spend for DTC ecom brands.
• 5+ years of Meta-specific depth: knowledge of platform quirks, policy landmines, and bidding behavior.
• DTC consumer scale-up background: experience in growing brands and pushing spend month-over-month.
• Structured operator behaviors: reliable forecasting, reporting cadence, and explicit decision rules.
• Creative fluency: ability to brief well and design effective testing structures.
• Multi-geo experience or the ability to manage multiple complex workstreams.
• Startup intensity: willingness to work 50+ hours/week in a high-ownership culture.

Requirements

• Not suitable if you’ve only worked with big corporate brands, B2B, or brand awareness campaigns.
• Experience should include hands-on operation rather than oversight through agencies or teams.

Nice to have

• Google Ads experience across search, performance max, demand gen, and YouTube.
• Experience with other channels like TikTok Ads, programmatic, and offline media.
• Healthcare or regulated category experience, particularly with GLP-1s or telehealth.
• Attribution sophistication: familiarity with MMM, incrementality testing, and skepticism of platform-reported ROAS.
• Multi-market operating history: experience running Meta across multiple countries.
• Management or mentorship experience with media buyers.
• Crisp written communication skills for translating platform mechanics into clear narratives.

Benefits

• Above market salary with early stage equity.
• Compensation: $150k–$250k/yr, including equity.
• Comprehensive medical insurance (if appropriate).
• Free membership with a clinic offering GLP-1s.
• PTO with a yearly minimum (≥2 weeks/yr + local national holidays).
• Fully remote team with distributed operations.
• Budget for personal development: books, courses, coaching ($1200/yr).
• Budget for personal wellness: gym, health apps ($1200/yr).
• Free biweekly health coaching.
• Macbook & work-from-home equipment provided as needed.

Our cultural standards

• Belief in the mission: dedicated to transforming the lives of patients.
• Unwavering integrity: maintaining ethics in ambiguous situations.
• Only the paranoid survive: embracing challenges with conviction.
• If we’re average we fail: focus on excellence in execution.
• Commitment to candor: full transparency and honest feedback.
• A maniacal sense of urgency: executing with speed and intensity.
• Enduring frugality: spending wisely and avoiding waste.
• Bulldozing barriers: being resourceful and shaping the world.
• Keep your head down: focusing on meaningful work over status.
• The power of focus: knowing and nailing your One Thing.
