Senior Full Stack Software Engineer

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 the partnerships, solutions, and data teams; understand how the catalog gets licensed and delivered, and where the current tooling slows a deal down

60 days: Develop and Cultivate

• Take a major feature or workflow from ambiguous ask to shipped, including its design
• Start raising the bar on quality, design consistency, and performance across the squad's code
• Become the engineer others come to when they're stuck in the presentation layer

90 days: Make an Impact

• Lead a significant initiative end to end, from talking to the people who need it through design, build, and rollout
• Identify at least one leverage opportunity (a reusable component, an architectural improvement, a workflow that should be self-serve) and drive it
• Have a visible effect on how the team ships: patterns adopted, reviews that teach, fewer things falling through cracks

What You Bring

Must Haves

• 5+ years building production web applications that real users depend on
• Deep TypeScript and React experience, with Next.js or a comparable full-stack framework in production
• You've shipped user-facing features end to end: UI, API, data model, and tests
• Strong design judgment: you can design a complex workflow yourself, hold a bar for visual and interaction detail, and articulate why one UI decision beats another
• Solid backend fundamentals: API design, Postgres, auth and permission modeling, and cloud services (we use AWS)
• You've built data-heavy or media-heavy interfaces and know how to keep them fast: streaming, pagination, caching, and knowing what not to load
• You've worked directly with the users of what you build and let that shape what you shipped
• Attention to detail without losing speed, and a bias to action
• Curious and proactive

Nice to Haves

• Experience with media playback in the browser (HTML5 video/audio, HLS, containers and codecs)
• Experience building UX over embeddings or vector search
• A portfolio, side projects, or shipped work that shows your design taste
• Experience building or maintaining a design system across multiple apps
• Familiarity with auth systems (we use Clerk) and permission modeling
• Experience working with sensitive or regulated data (HIPAA, PHI)
• Prior startup experience as a founding or early engineer
