Senior Full-Stack Engineer

Onsite Full Time IT & Technology

Own features end to end across our React + TypeScript front end and Supabase/Postgres back end — from the live coaching UI reps stare at on every call to the edge functions that serve cue cards in under a second. You ship weekly, sit on real sales calls, and care as much about the product as the code.

What you'll do

  • Design, build, and ship full-stack features across React/TypeScript, Tailwind, and Supabase (Postgres, edge functions, RLS).
  • Own problems end to end: scope, build, test, deploy, and measure — not just close tickets.
  • Keep the live coaching surface fast and reliable; profile and fix latency and rendering regressions.
  • Write clear, reviewable code and thoughtful PRs; raise the bar on testing and observability.
  • Pair with product and design, and sit on real sales calls to ground decisions in how the product is actually used.

What we're looking for

  • 5+ years building and shipping production web applications.
  • Strong TypeScript and modern React (hooks, data fetching, performance).
  • Solid relational data modeling and SQL; comfort with Postgres.
  • Experience owning features from design through deploy in a fast release cadence.
  • Clear written communication and an async-first working style.
  • Supabase, edge/serverless functions, or row-level-security experience.
  • Real-time systems (WebSocket/WebRTC, streaming) or low-latency UI work.
  • Early-stage startup experience.

How we hire

Our process has a few stages — it's a real role, so we take it seriously on both sides:

  • Intro call with the hiring manager — the role, your background, and what you want next.
  • Team conversations — meet the people you'd work with day to day.
  • A practical exercise drawn from real work — no whiteboard puzzles, no weekend-eating take-homes.
  • An on-site visit to our Saint Paul office to meet the team in person.
  • Final conversation and references, then an offer.

We move as quickly as we can and keep you posted at every step.
