Job Level

Tech Stack

About the role

  • Own frontend features end-to-end: From scoping and architecture to shipping and iterating—without waiting to be told what to do next.
  • Write clean, well-structured TypeScript: Produce code that your teammates are proud to review and that follows best practices.
  • Make pragmatic technical decisions quickly: Know when to go deep into a problem and when to move fast to hit a deadline.
  • Proactive maintenance: Identify and fix pain points in the codebase. If you spot something broken or brittle, you fix it.
  • Product collaboration: Work closely with product and design, but push back when something doesn't make sense for the user or the implementation.
  • Set the bar for quality: Maintain sensible abstractions and avoid unnecessary complexity to ensure long-term maintainability.
  • Contribute to technical direction: Have a voice in architecture decisions, tooling choices, and code standards.

Requirements

  • 8+ years of frontend experience: You have a proven track record of shipping complex SaaS products.
  • Expert-level TypeScript: You reach for strong typing instinctively, not as an afterthought.
  • Deep React experience: Expert knowledge of React and modern frontend tooling (Vite, ESLint, testing frameworks, etc.).
  • Self-starter mindset: You are comfortable with ambiguity, can define your own next steps, and don't need a detailed spec to get started.
  • High standards: You care deeply about readability, correctness, and long-term maintainability.
  • Shipping velocity: Proven ability to ship fast without accumulating crippling technical debt.
  • Product instincts: You think about the user experience, not just the code implementation.
  • Remote-first: Experience working effectively in a remote, async-first team.
Benefits
  • 32 days PTO (incl. public holidays)
