Conversion & Experimentation Manager

Open 12-month contract
Remote (UK)Conversion Optimisation

The Role

We're looking for a Conversion & Experimentation Manager to own conversion performance across client websites, landing pages, and onboarding flows. This is a 12-month contract role. SaaS experience is strongly preferred: you should understand how SaaS buyers evaluate products, what drives demo bookings and free trial activations, and the specific friction points in SaaS signup funnels. You'll run hypothesis-driven experimentation programmes delivering measurable uplift in demo conversions, trial signups, and MQL volume.

What You'll Do

  • Conduct comprehensive conversion audits on client websites and product signup flows
  • Develop experimentation roadmaps prioritised by impact, confidence, and effort
  • Design, set up, and analyse A/B and multivariate tests using experimentation platforms
  • Use session recordings, heatmaps, and user behaviour analytics to surface friction points
  • Collaborate with paid media and SEO teams to optimise post-click landing page experiences
  • Specify GA4 funnels, event tracking and conversion goals for the client’s team to implement
  • Produce test result reports with clear statistical significance analysis and recommendations
  • Develop insight-driven copy, layout, and UX recommendations for developers and designers
  • Present CRO roadmaps and test results to client stakeholders

What We're Looking For

  • 4+ years in CRO, digital experimentation, or UX analytics, including ownership of an experimentation programme. SaaS experience preferred
  • Hands-on experience running A/B tests in VWO, Optimizely, or similar, ideally on SaaS marketing sites or product signup flows
  • Strong understanding of statistical significance, sample sizes, and test validity
  • Proficient with GA4: events, funnels, audience segments, conversions
  • Comfortable working with heatmaps, session recordings, and qualitative data
  • Understanding of SaaS conversion journeys: trials, demos, PLG onboarding

Nice to Have

  • Experience with personalisation platforms (Dynamic Yield, Mutiny)
  • Basic HTML/CSS knowledge for implementing test variations
  • Familiarity with user research methods: surveys, interviews, 5-second tests
  • Experience with product analytics tools (Mixpanel, Amplitude, Heap)
