Job Description

We're searching for a Founding Product Engineer who'll own the entire user-facing surface of our training platform: everything from the daily interfaces our users interact with to the systems that make it all run. This role requires taking vague features and shipping them from start to finish. We care just as much about how the product feels to use as whether it technically works.

Job Responsibility

  • Take full ownership of product areas: scoping, designing, building, and iterating on them
  • Build clean, fast, polished web interfaces with Next.js that feel almost native
  • Write simple, performant backend services in Bun/TypeScript
  • Deploy and manage infrastructure on AWS (EKS, S3, and the usual suspects) using Kubernetes
  • Obsess over the small things, from loading states, smooth animations, solid error handling to edge cases
  • Make smart product tradeoffs with little hand-holding
  • Help shape our product culture and engineering standards as one of the first engineers on the team

Requirements

  • Proven experience shipping complete products, not just individual features
  • Serious frontend skills: comfortable with React/Next.js, CSS, and modern web APIs
  • A sharp eye for design and motion
  • Solid backend chops: can build APIs, work with databases, and troubleshoot production issues
  • Enough infrastructure comfort to handle AWS, containers, and Kubernetes
  • Ability to move independently in ambiguous situations
  • Real taste and strong opinions about what makes software feel good to use

Nice to have

  • Experience with Bun, or eagerness to dive in
  • Background in developer tools, infrastructure products, or building for technical users
  • Familiarity with Cloudflare (Workers, R2, etc.)
  • Time spent at early-stage startups or as an early employee
  • Open-source contributions or a public portfolio you're proud of
  • Comfort using design tools like Figma to mock things up yourself when needed

What we offer

  • bonus
  • equity
  • benefits
  • relocation assistance
