Senior Software Engineer

Svitla Systems Inc. is looking for a Senior Software Engineer for a full-time position (40 hours per week) in Romania. Our client builds AI agents that automate back-office functions for material manufacturers.

About the Role:

You'll build the infrastructure for autonomous manufacturing operations, and AI agents are coordinating complex workflows in parallel. Also, you'll provide transaction processing that can't fail when real money is moving. You'll stitch together the software layer for how physical goods actually move, building data pipelines that extract intelligence from unstructured supplier documents and emails, and delivering integrations to ERPs and freight systems where APIs barely work or don't exist.
