• Evaluate and integrate emerging AI coding capabilities into the team's toolchain, staying ahead of the curve on agentic AI developments.
• Define guardrails, review processes, and quality gates for AI‑generated code to ensure security, correctness, and maintainability.

Qualifications

• Deep proficiency in ReactJS (hooks, context, state management libraries such as Redux, Zustand, Recoil).
• At least 6+ years in full‑stack development with ReactJS, Typescript.
• Advanced Typescript knowledge or similar language including generics, decorators and advanced typing strategies.
• Strong experience in Python or similar frameworks (modular architecture, middleware, interceptors, guards, providers).
• Expertise in API design principals (REST, GraphQL, versioning, error handling, performance tuning).
• Proficiency with databases (SQL & NoSQL) and related tools.
• Strong command of modern HTML/CSS, responsive design and accessibility standards.
• Experience with design systems and component libraries.
• Familiarity with event‑driven architecture, messaging queues (Kafka, RabbitMQ, etc).
• Experience with AI Agent harnessed coding.
• Skilled in designing distributed systems and scalable applications.
• Knowledge of DevOps practices (Docker, Kubernetes, Terraform, CI/CD pipelines).
• Hands‑on experience with large‑scale, production‑grade applications.
