Prolific: Senior Product Designer

Headquarters: Remote, UK

Senior Product Designer

Team: Product, Research & Design

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

As part of our operational evolution we are looking for our first ever Senior Product Manager to be fully dedicated to building for our Research customers. You will take a ‘founder mindset’ to our heritage business, leading strategy and execution for a broad‑remit product team focused on academic and business research customers, many of them self‑serving, but increasingly more of them institutional or enterprise users.

Impact

You will be the Product person responsible for the product impact and outcomes of the team and future teams building in our Research Group. Online research is shifting rapidly with the advent of AI tools for good and bad (consider: AI‑enabled online research fraud) and this has reshaped the playing field. This role will inherit a platform which has been used and loved by researchers for over 12 years, with the opportunity to own, evolve and, where necessary, start again, for our next chapter. You’ll report directly into the VP Product of Prolific, and will work cross‑functionally while accountable for a stream‑aligned team.

Responsibilities

• You will be responsible for product managing a stream‑aligned team of your own. This means you’ll be accountable for the outcomes and impact of that team. You’ll be advising and building with the General Manager for Research, as well as varied collaborators.

Culture

Adding on to our Prolific Principles, we expect colleagues in the Product, Research, and Design Group to demonstrate reliability, grit, diplomacy, a bias for action, and a dogged focus on value – you’ll be a champion of these behaviors yourself, and in the culture of your team. Accountability and autonomy are two sides of the same coin, and we expect you to demonstrate both.

What you’ll be doing

• You’ll bring your varied Product career experience to bear to solve customer problems and create new opportunities for users to fall in love with Prolific.
• You’ll raise the bar of our product – and Product team – by making bets and building products that customers love and which drive commercial value for our business.
• You will be an unblocker and simplifier of complexity: colleagues will bring you problems, and emerge optimistic, with solutions.
• You’ll partner productively with Product Design, User Research, Analytics, and Engineering to find ways to deliver products in a test‑learn‑iterate fashion.

What you’ll bring

• An extensive and varied track record working embedded in technology teams alongside engineers and designers.
• Experience of optimising funnels in close collaboration with marketing and/or customer‑facing disciplines, or of working within a growth team.
• Competence or expertise in most or all of:
  • The industry’s prevailing Product/Engineering methodologies, hands‑on experience of Agile frameworks, continuous discovery, continuous delivery, JTBD frameworks, thin or vertical slicing, self‑organising teams, advocacy of ‘thinking in bets,’ test‑learn‑iterate loops, etc.
  • Strong commercial acumen alongside data‑informed decision‑making.
  • A storyteller’s flair, a model teamplayer, belief in ‘strong opinions weakly held’, personal accountability, and a relentless can‑do attitude.

Even better if you have

• Scale‑up or startup experience.
• AI/ML training / AI/ML development experience.
• A track record of giving back to your Design community.
