About The Position

Protege is hiring a 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. This role is ideal for engineers who want to ship whole features, not tickets, and grow fast by building directly for the people who use their work.

Requirements

2+ years building production web applications that real users depend on
Strong TypeScript and React, with experience in Next.js or a comparable full-stack framework
You've shipped user-facing features end to end: UI, API, data model, and tests
Design sense: you can take a feature from rough idea to a clean, usable interface, and you notice when spacing, hierarchy, or an interaction feels off
Comfort working across the stack, including Postgres and cloud services (we use AWS)
You notice when a flow is confusing or slow, and you fix it without being asked
Comfort with ambiguity and evolving priorities; you'd rather ship and iterate than wait
Curious and proactive

Nice To Haves

Experience with media playback in the browser (HTML5 video/audio, HLS, containers and codecs)
Experience building search or data-heavy interfaces over large datasets
A portfolio, side projects, or shipped work that shows your eye for UI
Familiarity with auth systems (we use Clerk) and permission modeling
Experience working with sensitive or regulated data (HIPAA, PHI)
Prior startup experience

Responsibilities

Ship features across our internal dashboard and customer-facing portal, from design through tests and rollout
Talk directly with the partnerships, solutions, and sales teams who use what you build; watch how they work, find the friction, and turn it into features
Design the interfaces you build: layout, hierarchy, interaction, and the empty, loading, and error states, often starting from a rough idea rather than a finished mock
Build the workflows our catalog 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
Implement playback, preview, and file-handling UX for content that lives across buckets
Build UI on top of embedding-based search so users can find the right clips within catalogs of millions
Extend and consume the API routes behind these surfaces (Next.js route handlers, Postgres, AWS)
Handle sensitive data correctly: scoped access, secure share links, and PHI-aware routes
Contribute to our shared design system and component library, and write tests as part of shipping
