We are working with a fast growing AI driven SaaS Platform Company where data underpins intelligent products used at scale. Large volumes of first party data flow through the platform and are shaped into trusted inputs for analytics, product features, and machine learning.
They are looking for a Senior Data Engineer to take ownership of the core data pipelines that make this platform work in practice.
This role is about working with real world data that directly feeds AI driven products. Data arrives incomplete, inconsistent, and sometimes ambiguous. Your role is to shape it into clear, reliable, decision ready datasets that product, analytics, and machine learning teams can confidently rely on.
Python and SQL are fundamental to the work.
You will design and maintain transformation logic, think carefully about data quality and edge cases, and ensure downstream behaviour remains reliable as data volumes and AI capabilities grow.
The work sits within a modern cloud data stack. You will work with technologies such as AWS, GCP or Azure, distributed processing frameworks like Spark, and modern data stores and warehouses such as Snowflake or BigQuery. The emphasis is on building robust, well structured data logic that scales alongside the platform.
You will be part of a collaborative and supportive engineering team where quality, clarity, and long term thinking are valued. Different perspectives are encouraged, and engineers are trusted to contribute in their own way. Alongside the hands on work, you will mentor and support other data engineers through code reviews, shared problem solving, and thoughtful technical guidance.
What we are looking for
- Strong, hands on experience using Python and SQL in production environments
- Experience building and maintaining data pipelines using technologies such as Spark, Snowflake, BigQuery, or similar
- Experience working in cloud environments such as AWS, GCP or Azure, with an understanding of data processing at scale
- Confidence working with messy, real world data and improving it through careful transformation and validation
If this role aligns with your experience using Python and SQL and you enjoy building the data foundations that power AI driven products while supporting other engineers to do their best work, we would like to hear from you.
