Backend Developer

Backend Developer: Design scalable systems, develop performant code, manage databases, ensure security, and collaborate with teams. Proficient in Node.js, Python, and cloud platforms.

Roles and Responsibilities:

1. System Architecture and Design:
   Develop and maintain backend architecture: Design scalable, high-performance systems and APIs that can support multiple web and mobile applications.
   Implement microservices architecture and ensure efficient communication between services.
   Design and maintain databases (relational and nonrelational) ensuring optimal performance, scalability, and data integrity.
2. Backend Development:
   Write clean, maintainable, and efficient code in backend technologies such as Node.js, Python, etc. or any other relevant languages.
   Develop RESTful and GraphQL APIs, ensuring proper documentation and versioning.
   Continuously work on optimizing backend performance for web and mobile applications to reduce latency and increase response time.
   Develop solutions that can handle high traffic and ensure the system scales effectively.
3. Collaboration and Communication:
   Work closely with frontend developers, mobile developers, product managers, and UX/UI designers to ensure seamless integration and smooth product development.
   Provide technical leadership, code reviews, and mentorship to junior developers, helping them grow their skills.
   Clearly communicate progress, risks, and challenges to management and other stakeholders in the product development process.
4. Database Management:
   Design and optimize complex SQL or NoSQL databases (e.g., MySQL, PostgreSQL, MongoDB, MariaDB, etc.) and ensure they are reliable and performant.
   Implement strong security protocols for data storage and transmission, ensuring compliance with best practices and regulations (e.g., GDPR, PCI DSS).
5. DevOps and Deployment:
   Set up and maintain CI/CD pipelines for automated testing and deployment of backend services.
   Deploy and manage cloud-based systems (e.g., AWS, Azure, Google Cloud) and infrastructure-as-code (e.g., Terraform, CloudFormation).
   Implement logging, monitoring, and alerting tools (e.g., Prometheus, ELK Stack, etc.) to track system performance, identify issues, and ensure quick recovery.
6. Security and Compliance:
   Ensure the backend systems are secure by implementing best practices for encryption, authentication, and authorization (e.g., OAuth, JWT).
   Regularly audit code and systems for potential vulnerabilities and enforce robust security protocols across applications.
   Ensure the backend systems meet regulatory and compliance requirements such as GDPR, HIPAA, or ISO standards depending on the industry.
7. Problem Solving and Debugging:
   Quickly identify and resolve backend issues affecting web and mobile applications, ensuring minimal downtime.
   Continuously refactor existing code and processes to improve system performance and reliability.
   Work on reducing technical debt by improving legacy code, enhancing system reliability, and ensuring maintainability.
8. Automation and Testing:
   Write comprehensive unit and integration tests to ensure the robustness of backend services.
   Implement TDD practices to ensure code quality and reliability.
   Set up automated tools for load and performance testing to ensure backend systems are prepared for high traffic scenarios.
9. Version Control & Documentation:
   Use version control systems (e.g., Git, GitHub, GitLab) to manage codebases, ensuring proper branching, merging, and collaboration practices are followed.
   Create and maintain detailed technical documentation for backend services, APIs, and system architecture to ensure transparency and ease of maintenance.
10. Innovation & Continuous Improvement:
    Stay updated on the emerging backend technologies, frameworks, and best practices, and integrate them into the product roadmap where beneficial.
    Participate in regular retrospectives and team meetings to identify areas for improvement in processes, technology, and collaboration.

Key Skills & Competencies:
Proficiency in backend programming languages (e.g., Node.js, Python, Java, etc.).
Strong experience with relational and non-relational databases.
Expertise in API design and development (REST, GraphQL).
Experience with cloud platforms (AWS, Azure, Google Cloud) and CI/CD pipelines.
Strong understanding of data structures, algorithms, and system design.
Familiarity with DevOps practices, containerization (Docker, Kubernetes).
Strong problem-solving and debugging skills.
Excellent communication and collaboration skills.
