Senior Frontend & Fullstack Engineer (TypeScript / PHP / Product Design)

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
