Product Engineer (Frontend & Design)
About the Role
FX Replay is looking for a Product Engineer with a strong frontend and product design background. We're looking for someone who can operate across product design, frontend engineering, and growth—someone with strong UI taste who can design polished experiences, build them hands-on in code, and care deeply about how they perform and convert.

This isn't a traditional frontend engineering role, nor is it a product design role. It's a Product Engineer role that blends product design, frontend engineering, and experimentation. You should be comfortable designing interfaces, building interactive prototypes, and working with our design system in Figma while also independently shipping real, production-ready experiences.

We need someone who is more design-forward than a traditional frontend engineer—someone who naturally thinks like a product builder, makes strong UI decisions, raises the visual quality of the product, and doesn't rely on a separate designer to polish every detail before release.





You'll work primarily in ploy.ai (our product, built with Astro, React, and TypeScript), where you'll design, build, and optimize acquisition funnels, landing pages, pricing and checkout flows, subscription experiences, plan-limit interactions, and other growth-oriented product journeys.

Just as importantly, you're genuinely strong in Astro and React and comfortable working directly in the codebase. You should be able to jump into unfamiliar code, understand it quickly, investigate issues independently, and deliver production-ready solutions while maintaining high standards of design quality, usability, responsiveness, accessibility, and conversion.

Above all, we're looking for someone who is growth-driven and experimentation-minded—a Product Engineer who naturally frames product decisions around user experience, business impact, experimentation, and continuous improvement.

What You'll Do
Design, build, and maintain polished
