Data Engineer - Data Platform Modernisation
Harnham is partnering with a major European consumer organisation on a large-scale modernisation of its data platform.
Operating across multiple markets with millions of consumers, the organisation has grown significantly over time, resulting in a complex data estate spanning different technologies, platforms and legacy environments.
They are now investing in consolidating this into a standardised, modern Snowflake-based data platform and are looking for experienced Data Engineers to help accelerate the migration.
The Role
You'll join a dedicated migration project, working alongside an established internal Data function to move legacy workloads onto the organisation's modern data stack.
This isn't simply building new Snowflake pipelines. You'll need to understand existing workloads across technologies such as Redshift, EC2, R and Python, determine how they work, and redesign them within the new architecture.
