Job Summary

You will own the end-to-end experimentation process for a high-velocity DTC growth engine, from ideation and setup through analysis and readouts, while coordinating engineers and designers to maintain momentum.

  • Own the experiment pipeline and prioritised roadmap to unlock high-impact insights.
  • Lead end-to-end testing, QA, and weekly learnings with clear, actionable readouts.
  • Coordinate with Growth Engineers and a Designer to keep velocity and momentum steady.

Job Description

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 "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.

Requirements

  • Experience: You27ve spent 4+ years running a high volume (>hundreds) of experiments for DTC ecommerce brands in high-pace, high-transaction-volume environments.
  • Workstream: You27ve had dozens of tests in flight simultaneously, unblocked every build, and laid out a roadmap that27s coherently sequenced and continues to progress forward. You don27t get overwhelmed easily.
  • Hands-on: You27ve personally owned end-to-end testing, from ideation and setup all the way to QA and readouts. You27re near the metal and haven27t 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. You27re 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 don27t need your hand held.

Preferred

  • 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 don27t 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: You27ve likely run experimentation across multiple markets/geographies and know the practical patterns, particularly in the UK + EU.

Benefits

  • Healthcare: comprehensive medical insurance (if appropriate).
  • Remote: our team is fully distributed across the world and functions fully remotely.
  • Personal development: budget for books, courses, coaching.
  • Personal wellness: budget for gym, health apps.
  • GLP-1s: free membership with a clinic offering GLP-1s.
  • Health coaching: free biweekly health coaching so you stay healthy.
  • Work coaching: free biweekly work coaching so you stay sharp + calm.
  • Equipment: Macbook & work-from-home equipment provided as needed.
  • What are we missing? We're still early so you get to shape our culture.
