This is a hands-on engineering role - you'll contribute directly to production code, build pipelines, and review implementations while shaping the long-term data platform architecture. You'll operate as the technical authority for DFP - guiding design patterns, ensuring code quality, and solving complex problems in distributed data systems. You'll collaborate closely with peer charters to ensure the data foundation remains reliable, scalable, and production-ready. Data Platform Architecture * Lead the hands-on design, coding, and evolution of DFP's cloud-native data architecture (AWS/GCP/Snowflake). * Architect and implement scalable ingestion and transformation pipelines using Fivetran, Databricks, and Airflow/DBT. * Design and code modular data services and APIs that unify campaign, conversion, and audience datasets across 20+ marketing platforms. * Build and optimize schemas, transformations, and ETL logic for high-performance, reusable data workflows. * Contribute directly to the DFP codebase (Python, SQL, Spark) - developing pipelines and infrastructure alongside the engineering team. * Establish data versioning, testing, and governance frameworks ensuring reliability, lineage, and compliance. Data Engineering Leadership * Drive best practices in data modeling, CI/CD, code reviews, and performance optimization. * Collaborate across engineering teams to define data contracts, schema validation rules, and automated quality checks. * Mentor junior engineers by pairing on code, reviewing pull requests, and helping them deepen technical maturity. * Participate actively in sprint planning and retrospectives, ensuring engineering execution aligns with platform goals. * Partner with Product and Data Science teams to translate analytical requirements into efficient, production-grade data solutions. AI-Ready Infrastructure * Design and maintain pipelines supporting Retrieval-Augmented Generation (RAG) and Context Engine workflows. * Build high-performance APIs and caching strategies enabling low-latency data access for AI agents and orchestration systems. * Implement vector-based data retrieval layers (pgVector, Pinecone) and ensure efficient embedding pipelines for AI contexts. * Partner with AI teams to monitor data latency, cost efficiency, and observability metrics. Collaboration & Governance * Partner with Platform Operations and Security to enforce privacy, compliance, and access control frameworks (GDPR, SOC2). * Work cross-functionally with analysts, AI engineers, and platform leads to deliver production-grade, business-critical data products. * Lead by example in data documentation, pipeline testing, and lineage tracking - ensuring transparency and reproducibility across all pipelines. ## Related Videos - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [HTTP headers that make your website go faster](https://www.wearedevelopers.com/videos/1676-http-headers-that-make-your-website-go-faster) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Enjoying SQL data pipelines with dbt](https://www.wearedevelopers.com/videos/823-enjoying-sql-data-pipelines-with-dbt) - [AI Model Management Life Circles: ML Ops For Generative AI Models From Research to Deployment](https://www.wearedevelopers.com/videos/1152-ai-model-management-life-circles-ml-ops-for-generative-ai-models-from-research-to-deployment) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Data Analyst Salary in the UK](https://www.wearedevelopers.com/magazine/278-data-analyst-salary-in-the-uk) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london)
