Job Description

• Design, ship, and iterate experiments that measurably improve key growth metrics.
• Design and launch high-velocity experiments (A/B tests, pricing tests, onboarding improvements, upsell flows, paywalls, landing pages).
• Translate hypotheses into testable experiences.
• Make fast trade-offs between polish and speed.
• Contribute to experiment ideation - not just execution.
• Use data to inform design decisions and refine direction.
• Help define what “good” looks like in conversion, activation, and retention flows.
• Balance short-term optimisation with long-term product quality.

Requirements

• Have 3+ years designing consumer web or app experiences.
• Have worked in a growth, optimisation, or experimentation-heavy environment.
• Understand A/B testing principles and experimentation trade-offs.
• Are comfortable working with product analytics (Amplitude, HotJar, etc.).
• Care about business outcomes as much as user experience.
• Can articulate the “why” behind design decisions.
• Move fast without sacrificing thinking.
• Are comfortable with ambiguity and incomplete information.

Nice to have

• Experience designing paywalls or subscription flows.
• Experience with pricing or monetisation experiments.
• Experience in gamified or educational products.

Benefits

• Fully remote.
• Flexible working, with trust and autonomy (and occasional intensity).
• Dedicated work equipment.
• £2,500 annual learning budget.
• Annual company retreat.
• Regular company-paid lunches.
• Health insurance (where applicable).
• Enhanced parental leave.
• Pension / 401k options.
