Lead Data Engineer
As a Lead Data Engineer, you will act as the technical authority within the data engineering team, responsible for defining how data solutions are designed and built across the organisation.
You will own the day-to-day technical direction of the data platform, ensuring that pipelines, data models, and warehouse structures are scalable, maintainable, and aligned to best practice.
Working closely with the Data Engineering Manager and the Head of Data Engineering & Governance, you will translate strategic direction into practical engineering approaches, while mentoring engineers and driving high technical standards across the team.
This is a senior individual contributor role with significant influence, operating as a peer to the Data Engineering Manager, with a focus on technical leadership rather than people management.
Responsibilities
-
Technical Ownership & Architecture
- Own the technical design and implementation approach for data pipelines, warehouse models, and transformations.
- Define and evolve data modelling standards (e.g. star schema, incremental models, partitioning strategies).
- Ensure solutions are scalable, performant, and cost-efficient across the data platform.
- Review and approve technical designs and code across the team.
- Act as the primary escalation point for complex technical challenges.
-
Data Platform & Warehouse Ownership
- Act as the day-to-day technical owner of the data warehouse (BAU).
- Ensure consistency and maintainability across datasets, pipelines, and transformations.
- Drive improvements in performance, reliability, and observability.

Engineering Standards & Best Practice
- Define and enforce engineering standards, patterns, and reusable components.
- Promote strong practices in:
- version control
- testing and validation
- CI/CD for data pipelines
- Ensure high-quality documentation of data models and pipelines.
- Identify and address technical debt proactively.
-
Data Quality & Reliability
- Lead implementation of data quality checks and monitoring frameworks.
- Ensure pipelines are robust, observable, and alerting appropriately.
- Drive improvements beyond basic checks (e.g. volumetric, anomaly detection, trend validation).
- Support root cause analysis and resolution of data incidents.
-
Technical Leadership & Mentorship
- Provide hands-on technical guidance to engineers and senior engineers.
- Mentor team members on system design, coding standards, and problem-solving.
- Lead technical discussions, design reviews, and knowledge sharing.
- Support capability uplift across the team.
