• 3+ years of backend development experience.
• Strong expertise in Java (Spring Boot) or Node.js.
• Solid understanding of System Design (HLD/LLD, Distributed Systems).
• Experience with event-driven architectures (Kafka, RabbitMQ, async pipelines).
• Hands-on experience building low-latency, high-throughput systems.
• Strong database knowledge (PostgreSQL, MongoDB, etc.).
• Understanding of security, performance optimization, and reliability.
• Experience with CI/CD, Git, Docker, Kubernetes.
• Exposure to React / React Native is a plus.

Good to Have (Differentiators) :

• Experience in FinTech / Crypto / Web3 / Blockchain.
• Built systems for trading, payments, or real-time financial data.
• Experience with AI agents, automation pipelines, or agent-based systems.
• Exposure to parallel AI workflows (coding / testing / refactoring).
• Contributions to open source or technical blogs.
• Experience handling production-scale systems.

Key Responsibilities:

• Design, develop, and maintain scalable backend applications using Java and Spring Boot.
• Build and consume RESTful APIs and ensure secure, reliable API integrations.
• Develop microservices-based architecture and deploy applications in cloud environments.
• Work with cloud platforms such as AWS/Azure/GCP for application deployment and management.

• Implement CI/CD pipelines and support DevOps practices.
• Optimize applications for performance, scalability, and reliability.
• Collaborate with cross-functional teams including frontend, QA, DevOps, and product teams.
• Participate in code reviews, technical design discussions, and architectural decisions.
• Troubleshoot production issues and provide timely resolution.

Required Skills & Qualifications:

• 5–10 years of hands-on experience in Java (Java 8 or above).
• Strong experience with Spring Boot, Spring MVC, Spring Data, Spring Security.
• Solid understanding of RESTful API design & development.
• Experience in microservices architecture.
• Hands-on experience with at least one cloud platform (AWS / Azure / GCP).
• Knowledge of containerization tools like Docker and orchestration tools like Kubernetes.
