Here's what we’re looking for:

• Proven success in a product-centric engineering role—or strong desire to step into one.

• A passion for crafting beautiful, accessible interfaces for complex systems, with a keen eye for detail.

• Experience building and scaling enterprise-grade web apps and thinking holistically about user interactions.

• A collaborative spirit: you mentor teammates, thrive on design/code reviews, and inspire others to innovate.

• Proficiency in TypeScript/JavaScript, React, or Go (bonus points for design-system experience).

• Strong communication skills in English for daily collaboration with our U.S.-based team.

Why you’ll love it here:

You’ll join a tight-knit, high-impact team where your ideas shape product direction and your code powers world-class digital experiences. We value clear communication, thoughtful design, and a culture of continuous learning.
