  • Raise the engineering bar across performance, accessibility, reliability, and code quality
  • Mentor other engineers and help shape the engineering culture as the team scales

Qualifications
  • 6+ years of frontend engineering experience with deep expertise in React and TypeScript
  • Strong architectural instincts and experience building complex, data-heavy, user-facing products
  • Ability to break down ambiguous problems and drive from concept to shipped solution
  • Track record of owning large product surfaces end-to-end
  • High standards for UI polish, edge-case behavior, and accessibility
  • Comfort working closely with design and product leadership
  • Bonus: experience with Microsoft Office add-ins, LLM-powered products, or legal tech
