Responsibilities:

• Design feature-flag architecture for multi-tenant SaaS
• Implement backend evaluation logic per request
• Support targeting rules (tenant, plan, environment, percentage rollout)
• Build internal tools/SDKs for developers
• Create an admin UI for managing flags and rollouts
• Add minimal logging/monitoring for feature behavior

Technologies:

• TypeScript, Next.js/Node.js
