• Participate in on-call rotations, respond to incidents, and drive continuous improvement of system reliability.
• Build and maintain observability into your systems through metrics, logging, and distributed tracing.
• Occasionally work across the stack, contributing to the React/TypeScript frontend as features require.
• Mentor engineers through code reviews, pairing sessions, and sharing knowledge about system design and best practices.
• Balance technical debt against feature delivery, making thoughtful trade-offs based on business priorities and technical constraints.
