PERETZ.agency is looking for a Middle / Strong Middle Front-End Developer based in Ukraine.

We currently have two large digital projects moving into active development and are looking for a developer who can take real ownership of the front-end side of the work.

Our stack:

React / Next.js / TypeScript

We build custom digital products, complex websites, e-commerce platforms, and business systems. This is not a role focused on assembling template websites or making minor UI changes.

You will work with custom designs, complex interfaces, and projects that continue to evolve after launch.

What we’re looking for

• Solid commercial experience with React, Next.js, and TypeScript
• Strong understanding of responsive front-end development
• Ability to accurately translate custom UI/UX designs into production interfaces
• Experience with APIs and back-end integrations
• Attention to detail in typography, spacing, animation, and interface behavior
• Ability to understand an existing project before adding another layer of code
• Independence and responsibility for your part of the project

The format

We are open to full-time cooperation or contract/project-based work.

There are already two substantial projects ready for active development, so this is not a vacancy published “for the future.”

The position is currently focused on developers based in Ukraine.

About PERETZ

PERETZ is a digital strategy and product agency working across the US and European markets.

We work at the intersection of business strategy, design, technology, and digital systems - building products that are expected to grow and evolve, not simply launch and disappear.
