Customize and configure AI agents for STAT-specific workflows and establish team norms for responsible, effective AI use in a compliance-sensitive context
Track and communicate the productivity and quality impact of AI adoption across the team
Actively mentor engineers at all levels — finding teachable moments, delivering direct feedback, and investing in others' growth
