• Serve as the technical collaborator for new features and platform improvements, making thoughtful tradeoffs around reliability, performance, maintainability, and speed of execution.
• Partner closely with product, design, AI, and data teams to develop intelligent, data-driven capabilities that improve performance and user experience for customers and end users.
• Anticipate future product and platform needs, and proactively design solutions that support team growth, product expansion, and increasing scale.
• Improve system observability, resiliency, and performance to ensure our onsite experiences remain fast, reliable, and effective
