Senior Data Engineer

Are you ready to shape the backbone of a data‑driven organisation? NewDay are looking for a Senior Data Engineer to lead the design, build, and evolution of the core pipelines and platforms that power analytics, reporting, and sophisticated data science across our business.

How you'll contribute

- Leading the development and optimisation of ingestion and transformation pipelines using technologies such as Spark, Scala, Python, AWS, DBT, and Snowflake

- Architecting and evolving the organisation’s Data Lake environment to ensure it remains robust, scalable, secure, and future‑ready

- Owning and improving ETL processing, table refreshes, defect resolution, and other BAU activities, while driving automation to reduce manual effort

- Championing performance optimisation through concurrency, multi‑threading, automation, and best‑practice engineering patterns

- Guiding Agile delivery, mentoring engineers, and ensuring high‑quality, cloud‑native data solutions are shipped via CI/CD

- Integrating data from multiple sources and solving sophisticated data challenges with creativity, technical depth, and strategic thinking

- Influencing data engineering standards, patterns, and governance across the wider organisation

We're looking for these essential skills

- Hands-on experience using DBT to design, build and improve data transformations within a complex data environment.

- Engineering experience using Python and SQL, with the ability to solve complex data problems at scale.

- The ability to design and guide modern data engineering solutions, with knowledge of data modelling, ETL/ELT, data warehousing and scalable data pipelines.

- The ability to lead and develop Data Engineers, combining hands-on technical contribution with coaching, technical direction and ownership of delivery.

- An interest in AI and automation, with the technical curiosity to explore how emerging technologies could improve engineering quality, productivity and ways of working.

It's a plus if you also have these skills

- Experience using AWS or another major cloud platform. Our environment includes EMR, Athena, Lambda, S3, Glue and Step Functions, but we're open to transferable experience solving similar problems.

- Experience with Snowflake, Spark, Scala or Airflow, or transferable experience with comparable technologies and solving similar data engineering challenges.

- Experience with Git, GitHub and CI/CD practices, including tools such as GitHub Actions.

- Knowledge of real-time data processing, data governance, data quality or observability.

- Experience using AI-enabled engineering tools or automation to improve data engineering productivity, quality or reliability.

We know great candidates don't always meet every requirement. If you have strong data engineering foundations, hands-on DBT experience and experience solving sophisticated problems at scale, we'd encourage you to apply even if you haven't worked with every technology listed above.

The impact you’ll make
Your work will strengthen the foundation of our entire data landscape. By improving reliability, reducing manual intervention, and accelerating time to insight, you’ll unlock new opportunities for analytics, innovation, and strategic growth. You’ll help define how data engineering is done at NewDay — and ensure the organisation is ready for what comes next.
