Senior PHP Developer

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. Backed by a 50 million SEK investment from the H&M Group, we power leading names like COS, ARKET, & Other Stories, Weekday, Nudie Jeans, and Paul Smith. Brands like Holzweiler trust Centra to run operations in 20+ markets with small, efficient teams—a reflection of the platform’s flexibility and efficiency.

Why join Centra?

Building meaningful solutions

Here, developers are deeply involved in solving real business challenges—not just writing code. You’ll work closely with cross-functional teams to build solutions that directly impact the success of internationally recognized brands.

Engineering that challenges and inspires

You’ll tackle performance-critical systems, apply domain-driven design and use modern architecture patterns. Whether it’s designing a GraphQL API, or optimizing cross-border flows, your contributions will have both technical depth and business relevance. You’ll take real ownership of your work and help shape technical direction.

Growth beyond Senior

Our engineers’ development doesn't stop at “senior.” We support continued progress through both technical mastery and leadership opportunities—whether you want to deepen your expertise, shape architecture, mentor others, or lead teams. You’ll have the freedom and support to advance in the direction that suits you best.
