Senior Full Stack Developer with Angular & Java/Spring Boot

Svitla Systems Inc. is looking for a Senior Full Stack Developer with Angular & Java/Spring Boot for a full-time position (40 hours per week) in Argentina.

Our client is an information technology organization that develops, implements, and supports software and hardware solutions for its members. The company delivers advanced solutions, services, and support to more than 1,000 independent communications companies, energy cooperatives, and public power entities in all 50 states, American Samoa, Palau, and Canada. It is an industry leader providing information technology solutions, including billing, accounting, operations, automated mailroom services, third-party integration, and many others.

The SmartHub application is our end-consumer-facing application, where customers can log in to view and pay their bills, monitor their usage, report problems, and more. It is used by more than 5 million end consumers each month. We are in the process of rewriting the entire UI and re-engineering the application to use a new set of backend services and logic that have been built. This position is approximately 60% frontend and 40% backend.

A key aspect of this role is AI-assisted development. Our client has invested heavily in AI coding tools and development pipelines.

Comfort working in this AI-augmented development model is essential
