Middle Full-Stack Engineer

We are looking for a Middle Full-Stack Engineer to join our AI & Automation Engineering team and work on our Internal Operational Platform — a growing product designed to automate workflows across multiple departments at AI Digital.

The platform is being developed as a central place where teams can access tools supporting their internal processes. The team is currently expanding its functionality, supporting existing applications, and gradually bringing more workflows from different departments onto the platform.

This is a hands-on full-stack engineering role with a strong backend and integration focus, within an established engineering stack and in close collaboration with engineers and business stakeholders as the platform continues to evolve.

Responsibilities

• Build and maintain full-stack applications using Java/Spring Boot and React/TypeScript.
• Develop new functionality for our Internal Operational Platform and support existing applications as the platform continues to expand.
• Transform AI-generated and vibe-coded MVPs into reliable, production-ready applications while preserving the original product intent.
• Refactor prototype logic into clean backend services, typed APIs, PostgreSQL schemas, and maintainable frontend workflows.
• Design and implement PostgreSQL schemas and manage database migrations with Liquibase.
• Develop REST APIs following an OpenAPI contract-first approach and work with typed frontend API clients.
• Integrate applications with BigQuery and support reliable data publishing and integration flows.
• Implement and maintain backend observability using Spring Boot Actuator, Prometheus metrics, and structured logging.
• Contribute to application quality through testing, monitoring, maintenance, and production support.
• Collaborate with business stakeholders and other engineers to translate real workflows into practical technical solutions.
