Conversional is an AI sales execution platform. We connect customer interactions, bookings and sales data in one system, so sales activity turns into predictable revenue instead of guesswork: AI lead scoring, full pipeline visibility, complex multi-location scheduling, call attribution.


What you’ll do

  • Build and evolve our calendar and booking widgets: embedded on customer sites, used on every kind of device.
  • Build our enterprise dashboard: pipeline and lead views, reporting, coaching and performance tooling. Dense, high-volume data that has to stay fast and legible.
  • Own interaction and UI decisions end to end. You get problems and constraints, not finished designs.
  • Work with a modern frontend stack and modern tooling, and have a real say in what we adopt next.



What we’re looking for

  • 6+ years of professional frontend experience.
  • Strong React and TypeScript. Fluent in CSS, not dependent on a component library to make something look right.
  • Deep understanding of how the browser actually works, Not just the framework’s abstraction over it.
  • Experience with dense, data-heavy product surfaces: tables, filters, charts, dashboards, rather than marketing pages.
  • Demonstrable performance work: you can name something you made faster and how you measured it.
  • Real experience working with AI agents on production code, structuring tasks for them, reviewing their output, catching decisions they made for you.
  • Product and design instinct. You notice when a flow is annoying and fix it without being asked.



How we work

  • You will work in a remote team on a 40 hours per week basis
  • Our goal is a long-term work relationship. Our product is complex, so we prefer a stable and reliable team
  • We do value personal connections, so we organize personal get-together and meet in some nice location on this planet
  • We have a positive attitude and a culture of mutual help and responsibility
  • We practice radical candor: If something does not work, we say so. And then we move on better than before
