• Lead the design of highly scalable, fault-tolerant distributed systems serving 10M+ users
• Set the full-stack engineering standards across React/Next.js frontend and Node.js / Python backend
• Drive cross-team technical alignment — partner with Engineering Managers, Product, and Data leadership
• Author Architecture Decision Records (ADRs) and technical RFCs; own org-wide design reviews
• Identify and eliminate systemic engineering bottlenecks — performance, reliability, developer velocity
• Translate ambiguous business problems into clear, phased engineering roadmaps
• Own production SLAs, incident command, and post-mortem culture for your domain
