Build the data platform powering a new generation of AI-driven consumer intelligence. You’ll work at the intersection of AWS, large-scale behavioural data and agentic AI, creating scalable pipelines and data products that turn ethically sourced, consented consumer data into meaningful insights.

• Designing, building and optimising scalable AWS data pipelines and ETL/ELT processes
• Developing data solutions using Python, SQL and Spark
• Processing large and complex behavioural datasets
• Improving data quality, reliability, performance and monitoring
• Using Claude and other AI-assisted development tools to support delivery
• Collaborating with engineers, analysts and data scientists
• Identifying opportunities to automate and improve data workflows
• Contributing ideas as the platform and its data products continue to evolve

What we’re looking for

• Hands-on data engineering experience using Python and SQL
• Practical Spark or PySpark experience
• Experience building production data pipelines using AWS data services
• A good understanding of scalable ETL/ELT design and data quality
• Experience using Claude or another AI-assisted development tool, with the ability to review and validate generated code
• Strong communication skills and an interest in working within a small, collaborative team

This is an opportunity to work with cutting-edge data and AI technology, take ownership beyond one narrow area and help shape a platform as the business grows.
