Descripción Del Trabajo

Joining a fast-growing European logistics tech company building the infrastructure that makes last-mile delivery smarter, greener, and more reliable. This is a backend engineering role at the heart of a critical platform migration, embedded in an empowered product squad.


The challenge

The PUDO platform processes thousands of daily parcel events across Spain and Portugal on a large, battle-tested Java + Oracle codebase. The mission: keep that system stable and reliable while progressively migrating it to a modern Python + PostgreSQL stack. This is not a rewrite from scratch. It requires technical judgment, respect for what works, and the ability to plan and execute a migration without disrupting live operations.
