Key Responsibilities

• Architect, design, and develop scalable backend systems using Java (Quarkus, Spring Boot, Spring, Java EE).
• Own the architecture — ensure modular, extensible, and high-performance service design.
• Lead and mentor a team of developers; conduct code reviews, enforce best practices, and ensure high code quality.
• Collaborate with cross-functional teams (frontend, DevOps, product, data) to deliver integrated, end-to-end solutions.
• Design and optimize database schemas (MySQL, PostgreSQL) and ensure efficient query performance.
• Implement and maintain microservices and distributed systems with strong fault tolerance and observability.
• Drive the adoption of modern development workflows — Git branching strategy, CI/CD, and code quality automation.
• Analyze system performance bottlenecks, implement monitoring, and ensure smooth production deployments.
• Contribute to architecture reviews, technical documentation, and design discussions.
• Occasionally contribute to Python-based analytics modules or automation scripts.
• Work with AWS cloud services (EC2, S3, RDS, Lambda) for deployment, scaling, and infrastructure automation.

Required Skills & Qualifications

• 5–6 years of professional experience in backend application development using Java.
• Strong proficiency in Java frameworks: Quarkus, Spring Boot, Spring, Java EE.
• Proven experience in architecture design, system decomposition, and microservices design principles.
• Solid understanding of object-oriented design (OOD), design patterns, and SOLID principles.
• Strong experience with relational databases (MySQL, PostgreSQL) and query optimization.
• Good understanding of event-driven systems, RESTful APIs, and asynchronous processing.
• Proficiency in Git for version control and team collaboration.
• Strong analytical and debugging skills; ability to diagnose complex production issues.

Good to Have

• Hands-on experience with Python for data processing or analytics integrations.
• Familiarity with AWS cloud architecture and cost optimization practices.
• Experience with CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI).
• Knowledge of Docker/Kubernetes for containerized deployments.
• Exposure to NoSQL databases (MongoDB, DynamoDB, Cassandra).
• Experience with message queues (Kafka, RabbitMQ, or AWS SQS).
• Understanding of system scalability, caching (Redis/Memcached), and observability stacks (Prometheus, Grafana, ELK).

Soft Skills

• Strong leadership, mentoring, and communication skills.
• Proven ability to drive technical decisions and balance short-term delivery with long-term architectural health.
• Collaborative mindset — works closely with product, design, and operations teams.
• Passion for clean architecture, high performance, and continuous improvement.
• Self-driven with a strong sense of ownership and accountability.
