The Role

We are looking for a highly skilled and commercially aware Data Engineer to join Unity Advisory in an internal-facing role, working on our Core Internal AI & Data Platform. This is a senior, hands-on engineering position responsible for designing, building, and operating scalable data foundations that enable analytics, AI use cases, and data-driven decision-making across the firm. You will play a critical role in ensuring data is reliable, well-modelled, governed, and easily accessible for internal teams. While this role will initially operate in a hands-on capacity, there is a clear opportunity to help shape data standards, influence platform direction, and contribute to the build-out of a data team as the function scales.

• Develop robust data models and semantic layers using Snowflake and AWS RDS to ensure trusted, analytics-ready data.
• Implement and maintain modern data stacks across warehousing, ingestion, and orchestration tools.
• Optimise data tracking and collection frameworks, with a focus on high-quality first-party data strategies.
• Embed best practices around data quality, testing, observability, documentation, and reliability.
• Support governance and compliance requirements, including GDPR, cookies, and internal data standards.
• Deliver efficiency gains through automation, improved data workflows, and thoughtful technology choices.
• Collaborate closely with AI engineers, full-stack engineers, and platform leads to support advanced analytics and AI/ML experimentation.
• Contribute to the evolution of Unity Advisory’s internal data platform architecture and standards.

What You Bring

• 7+ years’ experience in data engineering, analytics engineering, or closely related roles.
• Strong hands-on expertise across:

• Data Modelling & Transformation: SQL, Python
• Warehousing & ETL: Snowflake, BigQuery, Fivetran, Airbyte, Snowpipe
• BI & Analytics Enablement: Looker, Tableau, PowerBI, hex.tech, Streamlit
• Cloud Platforms: AWS and/or Google Cloud

Nice to Have

• Exposure to AI/ML workflows and experimentation.
• Experience working on internal data platforms or shared data products.
• Background in professional services, advisory, or project-based environments.
• Experience helping scale data capabilities from early-stage foundations.
