About

Senior Data Engineer – AI & Data Orchestration London (Hybrid) Salary: Up to £60,00 to £80,000 + Equity + Bonus. Stop building pipelines that just move data. Start building intelligence. Our client is a fintech company at the intersection of behavioural science and financial technology. They don’t just crunch numbers — they understand why people make the decisions they do, and they’re using AI to make those insights scale. They’re looking for a Senior Data Engineer who gets excited about turning messy, multi-source data into elegant, AI-ready architectures. This person will be the architect behind the curtain, making sure their behavioural scientists, ML engineers, and analysts have the rocket fuel they need. What they’ll actually do: * Build rock-solid data pipelines across AWS (S3, Glue, Athena, Bedrock, OpenSearch) and Microsoft (Fabric, Power BI) * Wrangle data from everywhere: RDS, MongoDB, HubSpot, S3 lakes — you name it * Create the data foundations for their AI/ML initiatives (RAG workflows, LLMs, embeddings) * Make Power BI dashboards that actually refresh when they’re supposed to * Implement governance that doesn’t make people want to scream (metadata tagging, lineage tracking, the good stuff) * Collaborate with brilliant behavioural scientists and product teams who’ll challenge them in the best ways The ideal candidate will: * Know their way around AWS data tools (Glue/PySpark, Athena) and Microsoft Fabric * Be able to write clean Python and SQL in their sleep * Have battle scars from integrating CRMs (HubSpot, Salesforce) via APIs * Actually care about data quality, not just “it ran successfully” * Get a kick out of making complex data architectures simple and elegant * Be able to explain technical decisions to non-technical humans Bonus points: Experience with Delta Lake/Iceberg, real-time streaming, or LLM orchestration What’s on offer: * Work on genuinely interesting problems (behavioural + financial data = never boring) * Shape the data strategy from the ground up — real influence, not ticket-shuffling * Hybrid working with actual flexibility * EMI equity scheme (because they believe people should share in what they build) * Collaborate with world-class behavioural scientists and researchers * Performance bonuses tied to real outcomes The practical bit: * Location: London-based, hybrid model * Salary: Up to £80,000 * Reports to: CTO * Team vibe: Small, smart, collaborative — your voice matters from day one
