Full Stack Software Engineer

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.

- 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

- Ship your first features to production in both apps

- Sit with the teams that use our tools while they work; come back with a list of the friction you saw

- Build a working map of the catalog domain: how content is ingested, curated, sampled, and delivered, and which teams touch each step

- Own well-scoped features end to end with light guidance, from a one-line ask to shipped, tested product

- Make design decisions on your own features that hold up: clear layouts, sensible states, interactions that feel right

- Become the go-to engineer for at least one surface area (e.g., delivery exports or customer access flows)

- Deliver a meaningful feature independently, from talking to the people who need it through design, build, and rollout.

- Contribute at least one improvement to our shared UI components or testing patterns that other engineers pick up

- 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

- 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
