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.



* Own and evolve the existing Java + Oracle codebase while driving the migration to Python + PostgreSQL * Lead the rewrite of critical carrier integrations on the new stack * Introduce and champion automated testing in a codebase with no prior test coverage * Help shape the AI-assisted development workflow for maintaining and evolving the legacy system * Manage your own deployments and take accountability for what runs in production * Collaborate with Engineering and Product Managers across the full product lifecycle * Extensive Python experience with solid ecosystem knowledge * Proven track record working with and improving legacy codebases * Experience planning and executing technology migrations #J-18808-Ljbffr
