Head of Product Marketing

Head of Product Marketing 

Prolific

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models.

The role

We're looking for a Head of Product Marketing to run product marketing as a discipline at Prolific. You'll own how we position, message, and launch our products and participant capabilities to AI and Research customers - packaging platform, participant supply, and services into coherent solutions that land across very different buying contexts.

This is a player-coach role. You'll manage a team of three PMMs – each embedded in different parts of the business – while staying operational on the highest-stakes positioning and launches. You'll be the connective tissue between Product, Sales, and the vertical marketing teams, ensuring we speak with one voice about what Prolific does and why it matters.

You'll need to operate across very different buying contexts: technical AI teams evaluating data integration pipelines, academics navigating data quality and funding questions, and enterprise buyers building business cases. If you're energised by growing a PMM function in a world of complexity, this will be a good fit.

What you’ll be doing in the role 

• Lead and develop a team of 3 PMMs, setting direction, removing blockers, and building their craft across positioning, launches, and sales enablement
• Own Prolific's product positioning and messaging architecture – the foundational narratives that vertical teams and sales build on
• Build and run the product launch framework: the process, the templates, the cross-functional coordination that makes launches predictable and effective
• Own solutions packaging and go-to-market strategy for combination of platform, participants and services
• Partner with Product leadership to shape roadmap priorities based on market signal and competitive positioning
• Work directly with Sales leadership to understand what's landing in deals, what's not, and translate that into better narratives and sales enablement materials
• Conduct and synthesise market, competitive, and customer research to inform product strategy and go-to-market decisions
• Set the standard for PMM craft at Prolific – how we write, how we launch, how we measure impact

What you’ll bring to the role

• 7+ years in product or solutions marketing, with at least 2 years leading or managing PMMs
• Experience building PMM as a function – not just executing within an established playbook
• Proven ability to translate complex, technical products into positioning that lands with different buyer types
• Strong stakeholder management across Product, Sales, and executive teams – you know how to influence without authority and build trust with technical and commercial leaders
• Track record of shipping launches that moved business metrics, not just "got out the door"
• Excellent writing and synthesis skills – you can take messy inputs and produce clear, compelling outputs
• Experience in product marketing or solutions marketing for complex B2B products, marketplaces, or platform businesses - ideally with multi-stakeholder buyer journeys
