Company Overview: We are building Protege to solve the biggest unmet need in AI — getting access to the right training data. The process today is time intensive, incredibly expensive, and often ends in failure. The Protege platform facilitates the secure, efficient, and privacy-centric exchange of AI training data. Solving AI’s data problem is a generational opportunity. We’re backed by world-class investors and already powering partnerships with some of the most ambitious teams in AI. The company that succeeds will be one of the largest in AI — and in tech. We’re a lean, fast-moving, high-trust team of builders who are obsessed with velocity and impact. Our culture is built for people who thrive on ambiguity, own outcomes, and want to shape the future of data and AI. ABOUT THE ROLE Protege is hiring a Senior Software Engineer for our Presentation team, the squad that builds the surfaces where Protege's data catalog meets the people who use it. That means two products: the internal dashboard our team uses to catalog, curate, package datasets, and the customer portal where AI labs browse, stream, and evaluate content before they license it. This is a product engineering role in a TypeScript and Next.js codebase. You'll talk directly with the people who use what you build, design the interfaces yourself, and ship the whole feature: UI, API, data model, and tests. The datasets behind these screens are large and multimodal (video, audio, motion capture, documents, medical imaging), so a lot of the craft is making that volume feel fast, legible, and good to use in a browser. As a senior engineer, you'll take on the largest and most ambiguous initiatives on the team: the ones that span both apps, cross into other squads' services, or need someone to figure out what the right product even is before building it. You'll partner with the team lead on direction and priorities, lead design on complex workflows, and raise the bar for everyone shipping in this codebase. This role is ideal for product engineers who want to design what they build, talk to the people who use it, and own features end to end. WHAT YOU’LL DO: • Lead the team's larger initiatives from discovery through design, build, and rollout, such as search previews at catalog scale or the presentation of a new content modality • Talk directly with the partnerships, solutions, and sales teams who use what you build; understand the business context behind each request and bring that view back to the team's priorities • Design complex workflows and data-heavy interfaces yourself: information hierarchy, interaction patterns, and every state a screen can be in • Build the workflows our partnerships and solutions teams use every day: sample creation, customer access management, and delivery exports • Build the customer-facing experience for browsing, streaming, and evaluating multimodal samples • Make large multimodal datasets feel instant in a browser: streaming playback, previews, lazy loading, and export at scale • Build UI on top of embedding-based search so users can find the right clips within catalogs of millions • Decide what runs client-side, in a route handler, or in a backend service, and work with our data teams when the answer crosses squad boundaries • Handle sensitive data correctly: scoped access, secure share links, and PHI-aware routes • Set the bar for quality on the squad: testing, performance, design consistency, and UX detail • Lead design discussions, review code, and unblock other engineers • Turn repeated one-off UI and workflow patterns into reusable components in our shared design system WHAT SUCCESS LOOKS LIKE: 30 days: Learn and Build Relationships • Get productive in the codebase and ship your first improvements to both apps • Build a working map of the presentation stack: the two apps, the services behind them, and how content flows from ingestion to a customer's screen • Meet
