Lead Product Designer in London

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 our new Lead Product Designer at Prolific, you will take your place as one of the movers and shakers of Prolific's Product, Research, and Design Group.

Impact: You will be the Design person responsible for the impact and outcomes of one of the teams building our core data collector experience. This is a career‐defining moment to shape how some of the world's biggest technology companies are building AI.

Domain: You’ll bring experience crafting amazing product experiences for enterprise and B2B customers. You will be able to quickly absorb and synthesize large complex business systems and naturally spot ways to simplify them. In a fast‐moving and evolving market with emerging needs and priorities, you’ll apply your excellent research and usability testing skills to ensure best solution fit.

Responsibilities: You’ll report into the Head of Product Design, and will represent Design cross‐functionally across a product group while accountable for the design output of a stream‐aligned team.

Culture: Building on 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 Design 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’s experience and the Design team – by making bets and building products that customers love and which drive commercial value for our business.
• As a player/coach, you’ll be directly impacting the professional development of Designers across a product group, while solving problems hands on within your embedded team.
• You’ll partner productively with Product Managers, 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. We want to learn from your past experiences.
• Experience in either line managing or acting as player/coach for other Designers.
• An understanding and empathy, ideally via demonstrable experience, of the different needs businesses and enterprises have when it comes to their software products (B2B) vs what individual consumers expect (B2C).
• Competence or expertise in most or all of: The industry’s prevailing Design tools, models, and methodologies, hands‐on experience working with design systems, vision prototyping, usability testing, service design, data‐led decision making and design for accessibility.
• A storyteller’s flair, a model team player, belief in 'strong opinions weakly held', personal accountability, and a relentless can‐do attitude.

Even better if you have:

• Scale‐up or startup experience.
• A track record of giving back to your Design community.
