• Design, implement, and optimize end-to-end solutions for GenAI applications, from backend services to user-facing interfaces.
• Build modular and reusable UI components in Angular and React, ensuring responsive and accessible interfaces.
• Develop and optimize backend services and APIs (REST, GraphQL, gRPC) to support real-time AI-driven applications.

Backend Egineering

• Architect and maintain distributed microservices (synchronous and asynchronous) using Java, Python, and FastAPI.
• Integrate ML models into scalable, production-ready systems in collaboration with ML engineers and scientists.
• Manage workflow orchestration with DAGs and asynchronous task queues.
• Implement automated testing, CI/CD pipelines, containerization (Docker, Kubernetes), and cloud-native deployments (AWS, Azure, GCP).
• Ensure security, performance optimization, and fault tolerance in backend systems.

Frontend Engineering

• Collaborate with UX and product teams to create human-in-the-loop AI experiences with Angular and React.
• Implement robust state management (Redux, NgRx, or equivalent) for real-time, data-intensive applications.
• Optimize rendering, bundle size, and performance for enterprise-scale UIs.
• Lead UI testing (Jest, Cypress, Playwright, Jasmine, Karma) to maintain quality and reliability.

Collaboration & Leadership

• Work closely with cross-functional teams to deliver cohesive GenAI-powered products.
• Mentor junior developers, promote coding standards, and drive best practices across front-end and back-end development.
• Communicate effectively with technical and non-technical stakeholders, ensuring transparency and alignment.

Qualifications

• 7+ years of professional experience as a full stack or combined backend/frontend engineer.

• Backend expertise:
• Strong skills in Java and Python, with experience in microservices and distributed systems.
• Deep knowledge of FastAPI, OpenAPI, gRPC, and asynchronous workflows.
• Proficiency with SQL and NoSQL databases, distributed computing (Kafka, Redis, RabbitMQ), and performance optimization.

• Frontend expertise:
• Expert-level experience with Angular and React, including TypeScript, JavaScript (ES6+), HTML5, CSS3/SASS.
• Strong grasp of state management frameworks (Redux, NgRx, etc.).
• Proven ability to build responsive, accessible, and performant enterprise UIs.
• Cloud & DevOps: Hands-on with AWS/Azure/GCP, Docker, Kubernetes, and CI/CD pipelines.
• Strong understanding of security best practices across the stack.
• Excellent collaboration, problem-solving, and communication skills.
