📝 Opis główny / Wstęp
For one of our projects with an International company, NTT DATA is looking for a Senior DWH Engineer to work remotely full-time. This role will be focused on Backend rather than Frontend.
Your responsabilities:
- Design and optimize the data warehouse architecture: Develop, maintain, and enhance scalable DWH solutions in Snowflake, including data modeling (star/snowflake schemas) and performance tuning of complex SQL workloads.
- Build and manage data pipelines (ETL/ELT): Create and orchestrate robust data integration processes using Matillion, ensuring seamless ingestion from e-commerce, POS, and ERP systems with high data quality and reliability.
- Translate retail business needs into data solutions: Collaborate with stakeholders to deliver data models and reporting that support key KPIs such as sell-through, margins, stock turnover, and omni-channel performance.
- Ensure data governance, security, and compliance: Implement best practices for data quality, metadata management, and access control (RBAC), ensuring compliance with GDPR and cloud security standards.
Your profile:
- University, college degree, or education in computer science.
- At least 8+ years of IT working experience, including solid work experience in multinational companies.
- Strong expertise in Data Warehouse development and management (DWH design, optimization).
- Deep understanding of fashion/retail business processes and KPIs (sell-through rates, margins, stock turnover, markdowns, omni-channel metrics).
- Advanced proficiency in SQL (complex queries, performance tuning).
- Hands-on experience with Snowflake (cloud DWH platform), Matillion (ETL/ELT tool), and Strategy (front-end/reporting tool).
- Solid data modeling skills (dimensional modeling, star/snowflake schemas).
- Experience with data governance (quality, metadata management) and integration from e-commerce, POS, ERP systems.
- Familiarity with cloud security best practices (RBAC, encryption, GDPR compliance).
- Agile collaboration skills and ability to translate business needs into technical solutions.
- Italian speaking is a plus
- Fluent oral and written in English is a must.
If you are interested and available for this opportunity as freelance contractor, please share your CV in ENGLISH as soon as possible.
