AI-Driven Engineering Culture

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on.
AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions

• Troubleshoot and resolve complex production issues, taking full ownership of system reliability and performance
• Facilitate technical discussions and foster collaborative problem-solving across cross-functional teams

What we are looking for

• Extensive production experience with Java and deep understanding of JVM internals and ecosystem
• Strong system design capabilities with proven ability to document and implement complex architectures
