We rely on AI to significantly influence how work is done and to accelerate delivery, while maintaining a high bar for code quality, system reliability, and architectural clarity. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Preference for AI-free workflows or resistance to AI-assisted development is NOT aligned with how we operate. Strong engineering judgment, architectural ownership, and accountability remain essential. AI amplifies our engineers - it does not replace responsibility for technical decisions.
