Conversion Rate Optimization (CRO) Lead — Remote, $80k-$120k/yr inc

ABOUT AIOS AIOS is building the world’s first full-stack AI doctor. We’re at $400M ARR, growing from $10M/yr 12 months ago. We’re the world’s fastest growing AI doctor. We’re faithfully serving >200k/mo patients via Bolt Pharmacy, our main UK brand. We’re profitable. Our strategy exists at the intersection of two strong theses: 1. The AI doctor that wins will get to escape velocity using GLP-1s, the fastest growing consumer product in history. 2. The $2T European healthcare market is overlooked by the most talented builders. Our master plan: - Step 0 → $100M/yr by end of 2025: We went from $10M to $100M in 6 months serving the UK GLP-1 market. - Step 1 → $1B ARR by end of 2026: Over the last 12 months we've grown from 3k to 150k UK active GLP-1 patients. We’ll continue this growth curve to hit $1B ARR. - Step 2 → $10B ARR by end of 2028: Blitzscale Europe. We’ll be Europe’s largest GLP-1 provider. - Step 3 → $100B/yr by end of 2031: Get regulatory approval across Europe for our Full Autonomous Prescribing (FAP) system. Win contracts at scale with European payers to mass replace human labor. We’ll be the dominant full-stack AI doctor in Europe. - Step 4 → $1T/yr by end of 2035: With one line of code and zero human time, you can use AIOS to treat any patient globally with any medication. In so doing, we’ll become the world’s first trillion-dollar healthcare company. We’re a young, founder-led company. This is still Day 1 and all our work is ahead of us.

As Conversion Rate Optimization (CRO) Lead at AIOS (Bolt Pharmacy), your mission is to grease the wheels of the CRO machine. You’ll keep every plate spinning—ideation, QA, project management, and test analysis—so we never stop testing at maximum speed. CRO is one of our highest-leverage levers on paid efficiency and unit economics and is critical to scaling up from here. You'll own the day-to-day engine of experimentation across our funnel, including landing pages, intake flow, and checkout. This is a hands-on role, and you’ll live in the weeds running experiments each day. We run on Omniconvert, PostHog, and HEX, but you’ll remain tool-agnostic and able to operate across whatever testing + analytics stack is required. You'll keep CRO compounding across every market as we scale the UK and expand into the EU. Great performance in the role means the pipeline never stalls and we always have a full, prioritised roadmap, clean QA, and readouts the team can trust. If you really nail the role, you’ll be a leading candidate for future senior roles in the Performance Team. This is a full-time, fully remote role. You can work async in the timezone of your choice, provided you have sufficient overlap with European and US time zones (midday Pacific Time) when needed. You'll report directly to our Head of CRO (Michael McCann https://www.linkedin.com/in/michael-m-33b79642/). You'll also work most closely with our growing CRO and Web team, currently consisting of two Growth Engineers and one Growth Designer. KEY RESPONSIBILITIES - Test ideation & roadmap: You keep the pipeline full and prioritised, turning analytics, session data, research, and paid-performance signals into a steady stream of high-quality hypotheses, sequenced by expected impact. - Experiment setup: You structure clean experiments with a clear hypothesis, primary metric, sample size, and guardrails, so every test produces a decision rather than a debate. - QA hygiene: You QA every variant before it goes live, across devices and edge cases. Nothing broken, off-brand, or non-compliant reaches a user, and the funnel stays protected from regressions. - Analysis & readouts: You read results with real statistical rigour (significance, confidence, segment effects) and call the winner, the loser, or the "
