Conversion Rate Optimization Lead

Who you are

• Experience: You've spent 4+ years running a high volume (>hundreds) of experiments for DTC ecommerce brands in high-pace, high-transaction-volume environments
• Workstream: You’ve had dozens of tests in flight simultaneously, unblocked every build, and laid out a roadmap that’s coherently sequenced and continues to progress forward. You don’t get overwhelmed easily
• Hands-on: You've personally owned end-to-end testing, from ideation and setup all the way to QA and readouts. You remain close to the metal and haven’t just simply managed an agency and/or a team
• Funnel literacy: You understand the ad-to-landing-page handoff and how CRO interacts with paid efficiency (CAC, quality score, LP experience)
• Analytical: You possess a sharp analytics and CRO mindset. You're comfortable inside the data, naturally curious, and able to dig past top-line numbers into segments and behaviour. You have a hunger to improve and are constantly upskilling
• Structured: Written planning, explicit prioritisation, and a dependable reporting cadence are what you hang your hat on. Teammates can digest and apply your learnings immediately
• Autonomous: You operate with high ownership in a fast-moving environment. You measure yourself in outcomes, and the outcomes here require real pace. You don’t need your hand held
• Statistical sophistication: You may possess deeper stats fluency, from significance and power to sequential testing and guarding against false wins. This may not be a fully fledged strength yet, but the substrate is present
• Research: You likely have some degree of comfort with both qual and quant, from heatmaps and session recordings to surveys and user testing. This helps you source new hypotheses
• Regulated-industry CRO: You may have experimented inside a regulated industry before, where compliance shapes what you can test, say, and ship. You know how to keep velocity high without stepping over the line
• Technical: You don't need to code, but you maybe understand how websites and data work under the hood. You can translate ideas into precise, buildable requests for the dev + design team and QA what comes back
• Localisation: You've likely run experimentation across multiple markets/geographies and know the practical patterns, particularly in the UK + EU

What the job involves

• 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)
• You'll also work most closely with our growing CRO and Web team, currently consisting of two Growth Engineers and one Growth Designer
• 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 "inconclusive, here's what's next." Your readouts are legible and trusted
• Program management: You are the DRI for keeping the plates spinning. You coordinate the Growth Engineers and Designer, unblock builds, chase the pipeline, and make sure momentum never depends on one person's attention
• Analytics & reporting: You own a clear weekly cadence outlining what shipped, what won, what we learned, and what's next. The wider team can act on your learnings without needing to decipher them via bloated follow-up
