Senior Data Engineer

• Help bring our data platform to the next level and empower Chip to be a truly data-driven business
• Co-own the architecture of our data platform alongside the Analytics Engineer — not just implementing designs, but making the calls on how ingestion, modelling, and the semantic layer should actually work
• Provide technical leadership across the wider data engineering team as we grow
• Design, build, and run scalable, secure data pipelines across multiple sources — with an eye on compute sizing and query performance
• Co-own architecture decisions across ingestion, modelling, and the presentation layer — defining how the platform should work, not just building to spec
• Design and evolve our medallion architecture (Bronze, Silver, Gold) as the platform matures
• Define more detailed engineering standards — naming conventions, partitioning, testing strategy, contract templates
• Apply Databricks best practices and Infrastructure as Code across the platform
• Own governance patterns in Unity Catalog — permissions, access models, and how we handle sensitive data
• Set technical governance standards the rest of the team builds against
• Enable downstream consumers with self-service patterns, so the data team isn’t the bottleneck for every request
• Provide technical leadership across the data engineering team — mentoring other engineers, reviewing code, and raising the engineering bar
