• Define and enforce data modelling, data contracts, quality, and engineering standards.
• Partner with Analytics, Data Science, Product, Finance, and business teams to translate requirements into scalable data solutions.
• Lead technical and design reviews and act as a trusted advisor for complex data architecture decisions.
• Mentor Data Engineers and raise the overall engineering and modelling standards of the team.

Requirements

• Minimum 10+ years of Data Engineering experience, with experience operating at Staff, Lead, Principal, or equivalent level preferred.
• Proven experience designing large-scale data warehouses from the ground up.
• Strong knowledge of dimensional modelling, Data Vault, conformed models, and modern data architecture principles.
