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

Why Join Centra?

Our engineers 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.

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.

What You’ll Do.

You’ll tackle performance-critical systems, apply domain-driven design and use modern architecture patterns. Whether it’s designing an 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 our technical direction.

• Strong experience with modern PHP. Knowledge of GraphQL and REST APIs is a plus

• Passion for performance, clean code and software engineering best practices like CI and observability

• A problem-solving mindset and sharp attention to detail

• Collaborative spirit and strong communication skills, with fluency in English

• Proven ability to incorporate AI coding tools into development workflows while maintaining high standards of code quality and engineering discipline

• Strong knowledge of web application security, including common vulnerabilities (e.g. XSS, SQL injection, CSRF, SSRF, command injection) and how to prevent them in practice

• Experience implementing secure authentication and data protection patterns, including OAuth 2.0 / OIDC, MFA, session security, encryption (in transit and at rest), and secure secret management

• Familiar with modern security and operational practices, including secure HTTP standards (CORS, CSP, HSTS), dependency auditing (CVEs), rate limiting, least privilege, and integrating security into CI and observability workflows
