Senior Java Engineer (AI-Driven Engineering)

About Patrianna: Patrianna is a fast-scaling product development company headquartered in Gibraltar, with a dynamic, global team powering growth at the intersection of technology and entertainment. They build innovative solutions shaping the future of social gaming, delivering experiences to millions of players worldwide.

Driven by speed, ambition, and bold ideas, Patrianna is a product-creation and problem-solving team thriving in a high-performance environment. They seek exceptional talent—smart, adaptable, and motivated individuals eager to make an impact, scale business functions at pace, and continuously improve.

AI-Driven Engineering Culture: Patrianna is actively building an AI-driven engineering organization where artificial intelligence is a core part of software development—not an experiment, trend, or optional add-on. AI is embedded into workflows, from system design and prototyping to refactoring, testing, and code review. Engineers must be fully comfortable with AI-driven environments and treat AI as a primary productivity multiplier.

Strong engineering judgment, architectural ownership, and accountability remain essential. AI amplifies engineers’ capabilities without replacing their responsibility for technical decisions.
