Senior Analytics Engineer

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? You will build and own the data backbone of our new Data & Insights module. It’s a brand new team, greenfield development, everything to play for. You’ll take raw transactional data from our clients and transform it into a high-performance analytics engine that powers real-time and analytical dashboards, making key architectural decisions along the way to ensure scalability, reliability, and speed. What You’ll Do. • Build data pipelines. Design and orchestrate near real-time data ingestion from client databases (CDC, AWS DMS, GCP Datastream, Azure Data Factory/Fabric, etc.) • Standardise metrics. Define and implement a single source of truth for key fashion KPIs using SQL and transformation tools (dbt, Dataform, etc.) • Own performance and scalability so that everything goes faster. Architect caching and performance layers to support fast, reliable dashboards across 300+ clients, making pragmatic trade-offs between cost, latency and complexity. • Develop APIs. Design and maintain serverless APIs (e.g. Lambda, Cloud Run) that power the frontend experience. • Expand data sources. Evaluate, ingest, and integrate new third-party data sources alongside existing datasets. What We’re Looking For. • Experience building and owning data platforms or products from scratch, including making architectural decisions. • Expert-level SQL and strong experience modelling complex business domains. • Proven ability to design scalable data systems in a cloud-native environment (AWS, GCP, or similar.) • Comfortable making independent technical decisions within a product context, balancing speed, quality, and long-term maintainability. • Strong product thinking/product engineering mindset. You don’t just build tables, you understand how data drives decisions for customers and why a brand needs this data. • Experience with Infrastructure as Code (Terraform or CDK.) • MLOps experience is a plus You might be a senior data or analytics engineer who enjoys owning problems end-to-end, or a tech lead who prefers to stay hands-on while shaping architecture and product direction. Either way, you're excited about a role building a new module within an established company tackling complex problems in the e-commerce space. Our Recruitment Process.
