Set the technical bar: define what good code, design and reviews look like, lead design discussions, code reviews and architecture sessions, and record decisions
Shape and design the backend-for-frontend service with backend engineers, covering API contracts, authentication, role-based access and background processing
Design extensible patterns so new evaluation types, workflows and partner integrations fit cleanly as the platform grows into a shared service
Lead the implementation of components that span multiple services and modules, working across the stack from development to infrastructure
Make the platform reliable at scale, with no lost expert work and fast, stable performance for hundreds of concurrent users
Diagnose and resolve complex technical issues across distributed systems, and complete the most complex bug fixes
Design and maintain data models that support both operational and analytical use cases
