Backend Developer

Responsibilities

• Back-End Development: Design, develop, and maintain scalable, high-performance server-side applications and APIs, ensuring efficient integration with front-end and third-party systems.
• System Integration: Work with third-party services and APIs (e. g., Salesforce, SAP ERP, payment gateways, CRM systems) to ensure smooth and reliable data flow and synchronization.
• API Development: Develop and maintain RESTful APIs and microservices that integrate with various internal and external systems.
• Data Management: Implement and manage data storage solutions, including relational and non-relational databases, ensuring efficient data retrieval and processing.
• Collaboration: Work closely with front-end developers to integrate user-facing elements with server-side logic and collaborate with DevOps teams for deployment and performance monitoring.
• Optimization: Ensure the performance, security, and scalability of applications, optimizing code for speed and efficiency.
• Security: Implement security best practices to protect user data and prevent vulnerabilities, with particular focus on secure API design and data privacy.
• Testing and Debugging: Write unit tests, and integration tests, and perform debugging to maintain high-quality code. Continuously monitor and improve the robustness and reliability of the system.
• Agile Development: Participate in Agile/Scrum processes, attending sprint planning, daily stand-ups, and retrospectives. Ensure timely delivery of backend services.
• Continuous Improvement: Stay up-to-date with the latest backend development trends, technologies, and best practices.
  

Requirements

• Core Backend Technologies: Strong proficiency in Java (Spring, Spring Boot), Node.js, or Go Experience with microservices and API-first design.
• Database Expertise: Solid experience working with both relational (PostgreSQL, MySQL) and relational databases (MongoDB, Cassandra, Redis).
• System Integration: Experience integrating with large, complex third-party systems, including but not limited to Salesforce, SAP ERP, CRM platforms, and other enterprise applications.
• API Design & Development: Expertise in designing and developing RESTful APIs and Web Services(SOAP, REST), with a deep understanding of API authentication, authorization, and versioning.
• Cloud & DevOps: Experience deploying applications to cloud platforms like AWS, Azure, or Google Cloud. Familiarity with containerization (Docker, Kubernetes) and CI/CD pipelines.
• Security & Data Privacy: Strong understanding of security practices, including OAuth, JWT, and general web application security, with a focus on protecting sensitive data and compliance with standards like GDPR.
• Scalability & Performance: Knowledge of techniques to optimize the performance and scalability of backend systems, such as caching strategies (Redis, Memcached), load balancing, and horizontal scaling.
• Version Control: Proficiency with code versioning, branching, and merging in collaborative development environments.
• Testing & Quality: Experience with automated testing frameworks such as JUnit, Mocha, orJUnit5 and a strong focus on writing testable, maintainable code.
• Microservices & Distributed Systems: Experience in building and maintaining distributed systems and services using a microservices architecture.
• Integration Tools: Familiarity with ETL (Extract, Transform, Load)tools, middleware, and integration patterns for communicating with third-party systems and services.
• Message Queues & Event-Driven Systems: Experience working with message brokers likeRabbitMQ, Kafka, orSQSfor asynchronous communication in distributed systems.
• Team Collaboration: Strong ability to collaborate in an Agile development environment, working with front-end developers, product managers, and other team members.
  

Preferred
