Responsibilities

• Design, develop, test, and maintain scalable backend services using Java, Spring Boot, and established software engineering practices.
• Build modern web applications using React, TypeScript, reusable components, responsive layouts, and accessible interaction patterns.
• Develop and consume REST APIs using an API-first approach; maintain clear OpenAPI/Swagger contracts and error handling.
• Design modular, maintainable solutions using microservices and appropriate object-oriented and event-driven design patterns.
• Use Node.js where appropriate for lightweight services, backend-for-frontend components, integrations, or development tooling.
• Design and optimize PostgreSQL data models and queries with attention to integrity, performance, and audit history.
• Design and implement reliable integrations with internal and external systems using REST APIs, webhooks, messaging, and other appropriate integration patterns.
• Containerize applications and contribute to cloud-based deployment patterns, configuration management, and environment consistency.
• Build and maintain Jenkins-based CI/CD pipelines with automated testing, quality gates, and repeatable deployments.
• Instrument applications with structured logging, metrics, tracing, and actionable error reporting.
