Backend Developer

Key Responsibilities:

● System Architecture & Design: Design and implement scalable, secure, and highperformance backend solutions that handle large volumes of requests and data.

● Backend Development: Write efficient, maintainable, and testable code in Java, Node.js, and Python for our microservices architecture.

● API Development: Develop and maintain RESTful APIs, and work with GraphQL where appropriate, to support seamless integration with front-end services and external systems.

● Database Management: Design and optimize SQL ( PostgreSQL) and NoSQL (MongoDB, Cassandra, etc.) database schemas to ensure efficient data storage, querying, and integrity.

● Distributed Queuing Systems: Design and implement distributed messaging systems ( Kafka) to handle asynchronous processing and communication across services.

● Performance Tuning & Optimization: Identify bottlenecks and optimize systems for speed, scalability, and efficiency while maintaining high availability.

● Code Reviews & Mentorship: Provide technical leadership by conducting code reviews using SonarCube, mentoring junior developers, and promoting best practices in backend development. ● Testing & Documentation: Ensure robust testing frameworks are in place (unit, integration, end-to-end), and document backend solutions for clarity and maintainability.

● Continuous Integration/Continuous Deployment (CI/CD): Collaborate with DevOps engineers to implement CI/CD pipelines, automate testing, and streamline the deployment process.

● Collaboration: Work closely with front-end developers, product managers, and other stakeholders to deliver well-rounded solutions and ensure alignment with business objectives.

Required Qualifications:

● Experience: 3+ years of backend development experience with a strong focus on Java, Node.js, and Python.

● Databases: Expertise in designing and optimizing both SQL ( PostgreSQL) and NoSQL (MongoDB, Cassandra) databases.

● Distributed Systems: In-depth knowledge of distributed queuing systems (e.g., Kafka) and how they integrate with microservices architectures.

● API Development: Strong experience designing and developing RESTful APIs and working with GraphQL.

● Cloud Infrastructure: Familiarity with cloud platforms (AWS) and infrastructure-ascode tools (e.g., Terraform).

● Microservices Architecture: Experience with building and maintaining microservices architectures, leveraging containerization technologies such as Docker and Kubernetes.

● Version Control: Proficiency in using Git for version control.

● Security: Strong understanding of security practices, including secure authentication (OAuth, JWT), data encryption, and API security.

● Problem-Solving: Excellent analytical and debugging skills to solve complex technical problems and optimize system performance.

● Communication: Excellent written and verbal communication skills, with the ability to clearly document and explain complex technical concepts.
