• Define PQL and expansion signals with Sales/RevOps, validated against conversion outcomes, with a CRM handoff process
• Start a structured experimentation programme across onboarding, email and in-app
• Report on results, learnings and experiment outcomes
• Document journeys, segmentation logic, triggers, PQL definitions and naming conventions

Required qualifications

• 5-7 years in lifecycle, CRM, retention or growth marketing at a product-led or self-serve company, with a track record of moving activation, retention or expansion metrics
• Prior contract, consulting or agency experience, or a clear record of delivering scoped work independently to a deadline
• Hands-on ownership of lifecycle programmes for a freemium, free-trial or pay-as-you-go funnel
• Strong experience with email/CRM platforms (HubSpot or equivalent) and in-product messaging tools (Pendo, Appcues, Intercom, Braze, Customer.io, Iterable or similar)
• Experience defining activation, building behavioural segments and triggers, and using product usage data to drive messaging
• Analytical fluency: cohort analysis, activation and retention curves, funnel conversion, LTV; able to run own analysis in HubSpot/Hex or equivalent without a data team
• Experience designing and running experiments and knowing which results to trust
• Experience partnering with Sales/RevOps on PQL or usage-based handoff
• A clear communicator who can prioritise, push back and manage stakeholders without close supervision

Before you apply

• This is not a traditional B2B SaaS marketing role: demand gen, MQL/SQL pipeline, events and sales-led nurture are not the right background
