Overview

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure driving AI development. In a world where foundational AI technologies are commoditised, the quality and diversity of human-generated data differentiates products and models.

The Role

As our new Senior Product Designer at Prolific, you will be a key contributor within Prolific's Product, Research, and Design Group. Impact: You will design products, services, and customer experiences for groups such as data collectors, financial controllers, and integrating developers. This is a career-defining opportunity to shape how major technology companies build AI and interact with the humans who contribute to it. You will work in a flat, cross-functional team of engineers, product managers, and researchers and be expected to contribute in kind.

Domain: We operate in the infrastructural layer of AI models, providing fairly compensated human data to build, fine-tune, and align/evaluate AI systems. Success hinges on understanding and improving complex journeys for data collection from machines and humans, including related processes like payments and APIs. You’ll frequently operate with low signals and low data in emerging AI use cases and markets.

Responsibilities
You will be responsible for product design for a value stream and will be embedded in a team alongside engineers, product managers, and data scientists. You’ll build and advocate for functional and delightful customer journeys that deliver significant value. You’ll work experimentally and iteratively with colleagues from several disciplines. You’ll conduct user research independently with support from our consulting user researchers. You’ll be the person accountable for customer experience and satisfaction in your domain.

Our CultureWe build on Prolific Principles: demonstrate commercial acumen, reliability, grit, and diplomacy; operate with trust and empathy; be a champion of these behaviours within your team. Accountability and autonomy are key. We are committed to an inclusive and diverse team, offer flexible hours, a flat open culture, and meaningful share option allocation. Diversity of thought matters; we seek culture add, not culture fit.

What you'll be doing

• Designing meaningful products: Identify and solve a wide range of problems through discovery, definition and design.
• Think strategically: Look beyond the immediate task to connect the dots, shape the product at a high level, and ensure alignment with the bigger picture.
• Shaping outcomes that matter: Help define, monitor and improve product experience for Prolific users.
• Elevating design at scale: Contribute to our design system and evolve processes to enable faster, more consistent, and enjoyable experiences.
• Driving a culture of experimentation: Explore and outline a range of solutions to solve customer and business problems. Champion data-informed design and rapid prototyping to deliver value.

How you’ll do it

• Understand people deeply: Build deep understanding of motivations and behaviours of data collectors, account administrators, integrating developers, and participants through workshops, research and feedback loops.
• Design journeys with impact: Create flows, user journeys and mental models to help users achieve their goals.
• Bring ideas to life: Produce service maps, wireframes and prototypes to inspire clarity and collaboration.
• Validate and refine: Test and evaluate prototypes and experiments for usability, value and feasibility to solve the right problems the right way.
• Collaborate across disciplines: Work with product and engineering teams to co-create design solutions and rollout strategies.
• Inspire and influence: Articulate design decisions clearly across the Prolific team and help elevate the role of design and your vision.

What you'll bring

You are comfortable with asynchronous and synchronous work in a fast-paced, changing environment. You are a deep systems thinker who is curious about people's behaviour and passionate about how great design improves user productivity and enjoyment. You understand product design principles and have extensive practical experience applying them.

• Design tools, such as Figma.
• Experience with information architecture and mapping complex systems and business processes.
• Experience of interface design and a strong understanding of good visual and interactive design in dynamic contexts.
• Comfort with product analytics and A/B or multivariate testing
• Experience working in fast-paced environments.

Even better if you have

• Knowledge of B2B and Enterprise customer needs and how to delight them.
• Knowledge of the AI development landscape and how humans are involved in training them.
• Knowledge of developer experience, APIs, and common developer tools.
• Proven success in a scale-up environment.
• Inclusive design and accessibility.
