Centra; Wrocław; Hybrid; PLN 180,000 - 300,000; Full time

Job summary

Centra is building a data and insights module for its API‑first ecommerce platform. You will own data pipelines, standardise key fashion KPIs, and help design scalable data systems used by 300+ clients across the globe in a hybrid, office‑first model in Wroclaw or Stockholm.

You’ll transform raw transactional data into high‑performance tables that power real‑time dashboards, contribute to architectural decisions, and build serverless APIs while expanding data sources and ensuring reliability.

Qualifications

• 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

Responsibilities

• 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.
