Your journey with us
The life of a Senior Data Engineer is very diverse. From implementing, code reviewing, and debugging data pipelines to leading large teams in complex data migrations for our clients.
Your role and tasks can switch frequently depending on the project at hand, meaning that one day you might be building a data warehouse and the next you are assisting our cloud team with providing the right information for the ideal setup for a large data platform.
You will be the key link between Deloitte leadership, Client leadership, your own technical team and both the technical & business teams at the client.
Internally you will leverage your knowledge & experience to bring your fellow data engineers to the next level, while also build PoC’s accelerators that will help our clients in getting the most out of their data.
Key Responsibilities:
- Designing, implementing and maintaining Snowflake data platforms on Azure and/or AWS, integrated with the surrounding cloud services (storage, orchestration, identity, BI).
- Connecting heterogeneous source systems - ERP, CRM, operational, financial and third-party data - into a governed central platform.
- Translating business requirements into technical solutions, and challenging them where a simpler or more scalable design exists.
- Data modelling: creating a conceptual model and translating it into a logical and physical one.
- Building and optimizing ELT/ETL data flows (SQL, dbt, Snowpark, Python) and tuning warehouse cost and performance.
- Implementing platform security on Snowflake: RBAC role hierarchies, authentication and SSO, masking and row access policies, data classification.
- Enabling AI and GenAI use cases on the platform - Snowflake Cortex, vector search / RAG patterns, and the data foundations that make them work.
- Contributing to client workshops, architecture design sessions and deliverables, with growing autonomy.
- Supporting proposals and contributing to internal assets, accelerators and knowledge sharing.
