What You'll Be Doing

• Own the full growth experimentation cycle - from spotting opportunities in the funnel to shipping, measuring, and deciding what to kill or double down on
• Build and iterate on activation, onboarding, sharing, and retention flows that turn first-time users into daily habits
• Partner with product, marketing, and data to surface growth levers and ship improvements that compound over time
• Develop the experimentation infrastructure (A/B testing, attribution tracking, analytics tooling), so teams can move fast and learn faster
• Translate user behaviour and funnel data into practical product or engineering changes that improve outcomes
• Define success metrics before you build, evaluate impact honestly, and balance speed with strong product judgment
• Help shape how growth operates at Granola - the metrics that matter, the playbooks, and the bar for what good looks like

Requirements

• 5+ years of experience in growth, product, or full stack engineering, ideally with end-to-end ownership of experimentation, optimisation or conversion work
• Strong product sense and user experience, able to see problems from multiple perspectives and build solutions for all of them
• Good understanding of metrics, success measurement, and iteration
• Experience in a high-velocity startup or similar environment with fast-paced work, self-directed priorities, and shipping without detailed specs
• Comfort working across the growth stack including TypeScript, React, Node.js, product analytics tools, and A/B testing infrastructure
• Excited to work primarily in-person from the London office
• Effective communication and collaboration skills across product, marketing, and engineering teams in ambiguous, fast-moving environments
• Ability to thrive in a fast-paced environment with evolving requirements and priorities

Nice to Haves

• Curiosity about AI, product systems, and the mechanics of growth loops
• Passion for working in a startup environment and experience or strong interest in zero-to-one phases
• Personal qualities such as kindness, ambition, pragmatism, and a builder mindset
