Job Description

We're not just building an ecommerce platform. We’re reshaping how fashion & lifestyle brands scale globally.

Our API-first, headless SaaS platform supports over 300 brands in delivering localized, high-performance shopping experiences across 120+ countries.

Brands trust Centra to run operations in 20+ markets - a reflection of the platform’s flexibility and efficiency.

Why Join Centra?

This role gives real opportunity to shape technical direction and improve how engineering is done at Centra. You’ll build high-performance systems in Go and evolve our development practices through better tooling and modern workflows. Our teams operate with high autonomy, fast feedback loops, and strong ownership.

This is not just a backend role though. It’s an opportunity to define how modern engineering teams work - combining strong system design with AI-driven development to build scalable, future-proof platforms.

• Proven ability to incorporate AI coding tools into development workflows while maintaining high standards of code quality and engineering discipline.
• Excellent communication skills in English, able to explain complex systems clearly
• Strong ownership mindset with attention to detail and quality
• GraphQL experience is nice to have, but strong API design, backend fundamentals and the ability to learn quickly are more important
