Senior Data Engineer

Senior Data Engineer | Python | Airbyte | Apache | BigQuery | EducationTech | Remote, London | £70k   Looking to help shape Data Strategy for a scaling Tech-for-Good business?   I'm partnered with a AI‑first data and analytics platform built for schools, multi‑academy trusts and education groups. Their technology connects fragmented school data - attendance, behaviour, wellbeing, assessment, SEND and unstructured documents - and uses a multi‑agent AI system to surface actionable insights for school leaders in seconds.   They are in a high‑growth phase, backed by Innovate UK funding, with a roadmap spanning predictive analytics, supplier intelligence, and international expansion. The team is mission‑driven, remote‑first, and growing quickly - every hire has very meaningful impact.   They are looking for a Senior Data Engineer to build and maintain the data infrastructure that underpins the entire platform.   You’ll own and extend the ELT pipeline - Airbyte (OSS) for extraction, Airflow on Astro for orchestration, dbt via Cosmos for transformation - and the BigQuery lakehouse beneath it, with a semantic layer on top.   These are hands‑on, build‑and‑operate roles in a team that takes engineering quality seriously.   Core Responsibilities: ELT Pipeline Ownership: Extend and maintain the Airbyte → Airflow → dbt → BigQuery pipeline. Connector Development: Build custom Airbyte OSS connectors for MIS systems and third‑party platforms. dbt Modelling: Design and maintain dbt models across bronze/silver/gold layers. Lakehouse Engineering: Own schema design, optimisation, partitioning and clustering in BigQuery. Pipeline Reliability: Ensure data quality, observability and freshness across all pipelines. Architecture Contribution: Help shape the evolving data platform as the product and dataset scale.  In return, you’ll get a competitive salary of up to £70k, and very flexible work arrangements across the UK.   Unfortunately we cannot offer sponsorship at this time.   Please contact me at (url removed) to discuss further!   Senior Data Engineer | Python | Airbyte | Apache | BigQuery | EducationTech | Remote, London | £70k
