Founding Product Engineer
Own the experience from the first document upload to a fax someone can confidently send and track.
The opportunity
Fax brings files, recipients and delivery history into one browser workspace. You’ll work with the founder to turn the places where people get stuck into small, measurable improvements.
This role spans the interface, application services and the data behind them. A typical project might start with a failed upload, follow it through the queue and end with a clearer way to resume the draft.
What you’ll work on
- Build and maintain the upload, recipient, preview and account flows across the frontend and backend.
- Design reliable APIs and data models for drafts, files and account ownership.
- Trace bugs across the browser, server and workers, then add checks that catch the failure next time.
- Scope work with design and support and ship changes in increments that are easy to review.
What you’ll bring
- Experience shipping a full-stack web product and supporting it after release.
- Comfort with TypeScript, React, SQL and the boundaries between browser and server code.
- Ability to explain technical trade-offs and turn an ambiguous problem into a useful first release.
Useful, but not required
- Experience with Next.js, Postgres or Supabase.
- Work on document tools, file uploads or subscription products.
Your first months
- Walk through the fax workflow, trace a draft end to end and ship one improvement that makes it easier to complete.
- Own a larger piece of the review or account experience and agree on how to measure its effect.
