Principal, Data Analyst/BI Engineer

About the role

We are looking for a Principal, Data Technology to serve as a key technical anchor for the data and measurement ecosystem behind our client work. This is a builder's role, and you are equal parts data engineering expert and marketing technology specialist. You understand how modern platforms are architected, governed, and scaled; how semantic and analytical layers enable trusted decision-making; and how the underlying infrastructure, automation, and operational processes run reliably at scale. You are equally fluent in marketing technology and measurement strategy. You understand how customer interactions become measurable signals, how consent and privacy requirements shape data collection, and how those signals flow through an organization's technology ecosystem to support activation, optimization, and business intelligence. You'll support the full signal-to-insight lifecycle, from data capture and collection, through identity, consent, and measurement frameworks, into data pipelines, modeling, governance, and ultimately the reporting and analytical experiences that drive business decisions. This role is responsible for ensuring every layer of the ecosystem works together as a cohesive, scalable, and trustworthy platform. At DEPT®, we take an engineering-first approach to solving business problems with data. As a principal technical leader within the practice, you'll guide the direction for data and measurement capabilities while remaining hands-on to define architecture, challenge assumptions, and drive delivery with credibility.

• Privacy by Design: Maintain the compliance posture for data tracking, covering CCPA/CPRA, GDPR, and consent frameworks, ensuring measurement holds up in a signal-loss, cookie-deprecation environment built on durable first-party data.
• Practice & Team Leadership
• Raise the Bar: Set high technical standards and elevate the specialists around you through advanced code reviews and architectural workshops.
• Technical Face: Represent the practice's data capability to client stakeholders.
