<h1 style="text-align: center;"><span style="font-family: tahoma, arial, helvetica, sans-serif; color: rgb(126, 140, 141);"><strong>Human Data Quality Engineer (Founding Team)&nbsp;</strong></span></h1> <p style="text-align: center;">&nbsp;</p> <p style="text-align: center;"><span style="font-family: tahoma, arial, helvetica, sans-serif; color: rgb(126, 140, 141);"><strong><em>Prolific</em></strong></span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif;">Prolific isn’t just enabling AI innovation – we’re redefining it. While foundational AI technologies are becoming commoditized, Prolific’s human data infrastructure provides the high-quality, diverse data required to train the next generation of AI models. Through our platform, we empower researchers and companies to access a global, ethically curated participant base, ensuring cutting-edge AI research and training grounded in inclusivity and precision.</span></p> <p style="text-align: center;">&nbsp;</p> <p style="text-align: center;"><span style="font-family: tahoma, arial, helvetica, sans-serif; color: rgb(126, 140, 141);"><strong><em>The Role</em></strong></span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif;">As one of the founding members of Prolific's newly formed AI Data Services team, you'll help build the quality systems behind some of the world's most advanced AI models. Data quality is a strategic priority for Prolific, so this is a high-visibility role with direct exposure to senior stakeholders. This isn't a traditional QA role. We are not looking for someone to review data against a predefined checklist. We are looking for an innovative thinker that can leverage their expertise to define what good means where no definition exists yet.</span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif;">Acting as a strategic thought partner, you’ll work at the intersection of human data, machine learning, evaluation across frontier use-cases that define what high-quality human data looks like for the next generation of advanced AI. This means that much of the work involves novel problems with no established answer, so you’ll be comfortable working through ambiguity.. .&nbsp;</span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif;">Your primary focus is working directly with clients and alongside frontier AI labs, translating what their models need into robust human data and evaluation strategies. Rather than checking quality at the end of a project, you'll engineer quality into every stage of the lifecycle, from study design and participant strategy through to evaluation, launch readiness and client delivery.You will also work alongside our product engineering, and supply teams to define and build the quality infrastructure that will enable us to deliver high quality human data at scale.</span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif;">Much of the work you'll tackle won't have an existing playbook. You'll help create it.</span></p> <p>&nbsp;</p> <p style="text-align: center;"><span style="font-family: tahoma, arial, helvetica, sans-serif; color: rgb(126, 140, 141);"><strong><em>What You’ll Be Doing</em></strong></span></p> <ul> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Design the quality frameworks that underpin complex human data programmes, from evaluation rubrics through to launch readiness.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Work with clients as a strategic thought partner, challenging annotation schemas and data requirements when they won't produce the signal the model needs.&nbsp;</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Advise on project design and how the choice of schema can impact data quality.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Build quality upstream across the operational workflow, from recruitment, screening, and training through to writing guidelines and running calibration sessions.&nbsp;</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Build scalable quality systems, measurement frameworks and automated checks using Python and SQL.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Partner with product and engineering to build the quality infrastructure that delivers high-quality human data at scale.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Investigate data quality and integrity issues, identifying root causes and turning insights into scalable improvements.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Architect and build dashboards, monitoring and reporting that provide clear visibility into quality and operational performance.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Raise the quality capability across the company, upskilling operations and acting as a thought mentor to junior analysts.</span></li> <li style="font-family: tahoma, arial, helvetica, sans-serif;"><span style="font-family: tahoma, arial, helvetica, sans-serif;">Help define how Prolific approaches quality across new AI domains, shaping best practice as the team grows.</span></li> </ul> <p style="text-align: center;"><span style="font-family: tahoma, arial, helvetica, sans-serif;
