Frontier Ux Engineer Jobs

Human Data Quality Engineer (Founding Team) Prolific 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. The Role 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. 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.. . 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 h

Our Product Management team drives product initiatives from inception through execution, makes impacts and launches products/features across our global footprint. We collaborate closely with engineers, designers, analysts, marketers, and other cross-functional team members to ship remarkable features and products. Role Overview We are looking for a Senior Product Manager, Trading to own trading products on the Crypto.com App end-to-end. Retail trading is where users feel the product every day - and where volume, engagement, and retention compound. Every improvement you ship shows up in how people trade, how often they come back, and how Crypto.com wins share in a crowded market. Your mandate is to drive trading products from discovery through launch and iteration: roadmap clarity, feature definition, customer insight, and shipping at global scale. You will run your roadmap with independence within Trading's strategic priorities. You prioritize initiatives, cut tradeoffs, and make the call on what ships when. You report to the Senior Director of Product Management, who sets strategic direction. You own the how and the when. If you've shipped trading or financial products at scale, this will feel familiar. The difference is you'll be doing it at the frontier of crypto retail trading- perpetuals, spot, and adjacent markets- where the rails keep moving and the playbook is yours to write. No layers. No politics. What You'll Actually Do: Own the Trading roadmap. You set milestones, surface dependencies, and keep strategic priorities honest. You make the prioritization call when everything can't ship at once. Define and ship trading experiences. You write the specs, run user studies, iterate on feedback, partner with QA on test plans, and clear the backlog. Nothing in your charter goes live without your sign-off. Stay close to how traders actually behave. You interview and observe customers. You ask "Show me how you currently

P-150 At Databricks, we are passionate about enabling data teams to solve the world's toughest problems — from making the next mode of transportation a reality to accelerating the development of medical breakthroughs. We do this by building and running the world's best data and AI infrastructure platform so our customers can use deep data insights to improve their business.
