We’re working with a fast-growing AI SaaS business where data sits at the core of everything they build.

They’re looking for a Senior Data Engineer to take ownership of the pipelines that power their platform.

You’ll be working with real-world, messy data and shaping it into reliable, decision-ready datasets used across product, analytics, and machine learning.

Python/PySpark and SQL are central to the role.

The Role:

  • You’ll design and maintain data pipelines, handle edge cases, and ensure data quality as the platform scales.
  • The environment is modern and cloud-based, using tools such as AWS, GCP or Azure, alongside Spark, Snowflake or BigQuery.
  • You’ll also play a key role in supporting and mentoring other engineers through code reviews and collaboration.
  • You’ll be joining a supportive team that values different perspectives, encourages thoughtful problem solving, and gives engineers the space to contribute in their own way.

What we’re looking for:

  • Strong Python and SQL experience in production
  • Experience with Spark, Snowflake, BigQuery or similar
  • Cloud experience (AWS, GCP or Azure)
  • Comfortable working with complex, messy data
  • Experience owning pipelines end-to-end
  • Collaborative mindset with mentoring experience
