About The Position

Prolific for Researchers is continuing to grow and scale its direct and product-led growth motion (self-serve), and we're looking for a Growth Marketing Manager to own the full funnel for our PLG segment, from acquisition through to activation, lifecycle and retention. This role sits at the intersection of full-funnel PLG strategy and hands-on channel execution. You'll be the primary owner of how researchers discover, pilot and stick with Prolific through self-serve channels, and you'll also own paid acquisition strategy on behalf of the wider Prolific for Research marketing team, meaning your work directly supports Industry, Academic and Partnerships campaigns as well as PLG. It's a role for someone who wants genuine end-to-end ownership rather than a single stage of the funnel, and who's comfortable being the connective tissue between all marketing channels, product and lifecycle.

Requirements

4–7+ years' experience in Growth or Performance Marketing, with demonstrable ownership of an end-to-end product-led growth (PLG) funnel within a B2B SaaS environment.
Proven experience driving measurable improvements across acquisition, activation and retention—not just campaign execution.
Strong understanding of paid acquisition across Google Ads, Meta, LinkedIn and other digital channels, with experience shaping strategy and optimising performance.
Experience building and optimising onboarding, lifecycle and in-product engagement programmes using tools such as Pendo, Appcues or similar.
Strong analytical mindset, with experience measuring funnel performance, defining PQLs, and using platforms such as HubSpot, Metabase or equivalent to inform decisions.
Working knowledge of organic growth channels, including SEO, content-led growth and emerging search (AEO), alongside paid acquisition.
Confident cross-functional stakeholder manager, able to partner with Product, Sales, RevOps and Customer Success, balance competing priorities and influence decisions.
Comfortable working autonomously in a fast-paced, high-growth environment with end-to-end ownership.

Responsibilities

Own the end-to-end product-led growth (PLG) strategy for Prolific's self-serve customer journey, driving acquisition, activation, engagement and retention.
Develop and optimise onboarding, lifecycle marketing, in-product messaging, referral programmes and customer journeys to improve activation, adoption and long-term retention.
Own paid acquisition strategy across search, social and display, working with agency partners and internal teams to optimise performance, budgets and channel effectiveness.
Drive organic growth through SEO, content and emerging acquisition channels, continually testing new opportunities to grow the self-serve funnel.
Partner closely with Product, Sales, RevOps and Customer Success to define PQLs, optimise handoffs and improve the end-to-end customer experience.
Lead a culture of experimentation, using data and insights to continuously optimise funnel performance and measure success across acquisition, activation, conversion and retention.
