• Use Redis in production for caching, pub/sub messaging, and distributed locking.
• Build and maintain WebSocket-based features supporting high levels of concurrent activity.
• Implement and maintain payment integrations, including subscriptions, refunds, and reliable webhook processing.
• Develop and release LLM-powered functionality for external customers.
• Diagnose production issues where defects could result in financial loss, data problems, service disruption, or other material impact.
• Use LLM-based development tools responsibly to improve engineering productivity and code quality.
• Communicate technical decisions, risks, and tradeoffs clearly with company leadership and other stakeholders.
