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. 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?

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.

What You’ll Do.

As a Senior engineer, responsibility includes shaping the technical vision and architecture of platform domains with a strong focus on:

• Designing and evolving scalable, high-performance system in Go
• Driving system design decisions that support both single-tenant and multi-tenant architectures at scale
• Unifying and improving infrastructure and services to enable efficient scaling and reliability
• Driving AI-assisted engineering practices, including agentic coding and tool creation
• Partnering with Engineering and Product Managers to define the technical roadmap and future platform capabilities

What We’re Looking For.

• Proven experience designing, building and operating complex distributed systems
• Strong expertise in Go and backend engineering best practices
• Deep understanding of system design, scalability and performance optimization
• 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

Our Tech Stack.

• Languages: Go, PHP 8.3, GraphQL
• Databases: MySQL, Elasticsearch, Redis
• Infrastructure: Kubernetes, EKS, AWS, GCP, DigitalOcean
• Tools: GitHub, GitLab

Location and Logistics.

This team is based in Stockholm. We operate an office-first, hybrid working model with three days a week in the office.

Equality.

We’re committed to fair, inclusive hiring and to building a team with diverse perspectives. If you need adjustments during the process, please let us know.
