Job summary:
We're looking for a Senior Data Engineer to help us shape the future of our data platform. You'll play a key part in designing, building, and running modern cloud-based data pipelines that power insight and innovation across the business.
This is a hands-on role with the scope to influence strategy, lead technical delivery, and guide our transition to Snowflake. You'll work closely with senior stakeholders to translate business needs into practical data solutions, while helping the team continuously improve our data engineering practices.
If you enjoy solving complex data challenges, mentoring others, and seeing the impact of your work, we'd love to hear from you.
What you'll be doing
As a Senior Data Engineer, you'll be part of a growing, forward-thinking team that's modernising how we design, deliver, and use data across the organisation. You'll combine deep technical expertise with strategic thinking to make sure our data platforms are reliable, scalable, and future ready.

• Designing and developing data pipelines: Build and optimise data pipelines in a cloud environment (primarily Snowflake), enabling smooth and secure data flow across multiple systems.
• Leading our cloud migration: Drive the transition of existing on-premises ETL routines into a fully cloud based architecture. You'll identify opportunities to simplify, automate, and enhance our data processes along the way.
• Creating high-quality data models: Design and maintain logical and physical data models in Snowflake, ensuring they're well-structured, high-performing, and easily accessible to analytics and business teams.
• Ensuring data quality and reliability: Implement monitoring, validation, and automated testing so our data remains accurate, consistent, and trustworthy across all sources.
• Collaborating with cross-functional teams: Work closely with analysts, data scientists, product managers, and business stakeholders to understand their needs and translate them into data-driven solutions.
• Applying advanced engineering practices: Use technologies like DBT, Airflow, and containerisation tools to automate workflows and improve operational efficiency.
• Tuning and optimising performance: Leverage advanced Snowflake features such as clustering, caching, and resource monitors to maximise performance and cost-effectiveness.
• Driving innovation and process improvement: Identify ways to make our data platforms more efficient, sustainable, and easier to maintain, bringing in new ideas and best practices.
• Championing DevOps principles: Contribute to continuous integration and deployment processes, helping ensure smooth, repeatable data releases.
• Mentoring and supporting others: Share your knowledge, guide junior engineers, and help build a positive, inclusive engineering culture where everyone can learn and thrive.

• Around 7+ years' experience in data engineering, data warehousing, or similar roles.
• Proven experience with Snowflake and cloud-based data platforms.
• Strong SQL skills and experience in one or more programming languages (Python, Java, or Scala).
• Experience designing and implementing ETL/ELT processes and working with tools like DBT, Airflow, or similar.
• A strong understanding of data warehousing concepts, file formats (Parquet, ORC, Avro), and performance optimisation.
• Familiarity with DevOps practices and containerisation tools to support efficient deployment.
• The ability to communicate clearly with both technical and non-technical colleagues.
• A passion for mentoring, learning, and sharing knowledge within the team.
• Relevant certifications such as AWS Data Analytics or Snowflake certification.
