Senior Software Developer (Backend)

Roles and Responsibilities:

System Architecture and Design:
• Develop and maintain backend architecture: Design scalable, high-performance systems and APIs that can support multiple web and mobile applications.
• Microservices and distributed systems: Implement microservices architecture and ensure efficient communication between services.
• Data modeling: Design and maintain databases (relational and nonrelational) ensuring optimal performance, scalability, and data integrity.

Backend Development:
• Code development: Write clean, maintainable, and efficient code in backend technologies such as Node.js, Python, etc. or any other relevant languages.
• API development & integration: Develop RESTful and GraphQL APIs, ensuring proper documentation and versioning.
• Optimize performance: Continuously work on optimizing backend performance for web and mobile applications to reduce latency and increase response time.
• Handle concurrency & scalability: Develop solutions that can handle high traffic and ensure the system scales effectively.

Collaboration and Communication:
• Cross-functional collaboration: Work closely with frontend developers, mobile developers, product managers, and UX/UI designers to ensure seamless integration and smooth product development.
• Mentor junior developers: Provide technical leadership, code reviews, and mentorship to junior developers, helping them grow their skills.
• Stakeholder communication: Clearly communicate progress, risks, and challenges to management and other stakeholders in the product development process.

Database Management:
• Database design & optimization: Design and optimize complex SQL or NoSQL databases (e.g., MySQL, PostgreSQL, MongoDB, MariaDB, etc.) and ensure they are reliable and performant.
• Data security: Implement strong security protocols for data storage and transmission, ensuring compliance with best practices and regulations (e.g., GDPR, PCI DSS).

DevOps and Deployment:
• Continuous integration & deployment (CI/CD): Set up and maintain CI/CD pipelines for automated testing and deployment of backend services.
• Cloud infrastructure management: Deploy and manage cloud-based systems (e.g., AWS, Azure, Google Cloud) and infrastructure-as-code (e.g., Terraform, CloudFormation).
• Monitoring & logging: Implement logging, monitoring, and alerting tools (e.g., Prometheus, ELK Stack, etc.) to track system performance, identify issues, and ensure quick recovery.

Security and Compliance:
• Data protection & privacy: Ensure the backend systems are secure by implementing best practices for encryption, authentication, and authorization (e.g., OAuth, JWT).
• Security audits: Regularly audit code and systems for potential vulnerabilities and enforce robust security protocols across applications.
• Compliance with regulations: Ensure the backend systems meet regulatory and compliance requirements such as GDPR, HIPAA, or ISO standards depending on the industry.

Problem Solving and Debugging:
• Troubleshoot production issues: Quickly identify and resolve backend issues affecting web and mobile applications, ensuring minimal downtime.
• Optimize and refactor: Continuously refactor existing code and processes to improve system performance and reliability.
• Technical debt management: Work on reducing technical debt by improving legacy code, enhancing system reliability, and ensuring maintainability.

Automation and Testing:
• Unit & integration testing: Write comprehensive unit and integration tests to ensure the robustness of backend services.
• Test-driven development (TDD): Implement TDD practices to ensure code quality and reliability.
• Automated performance testing: Set up automated tools for load and performance testing to ensure backend systems are prepared for high traffic scenarios.

Version Control & Documentation:
• Version control: Use version control systems (e.g., Git, GitHub, GitLab) to manage codebases, ensuring proper branching, merging, and collaboration practices are followed.
• Documentation: Create and maintain detailed technical documentation for backend services, APIs, and system architecture to ensure transparency and ease of maintenance.

Innovation & Continuous Improvement:
• Research & development: Stay updated on the emerging backend technologies, frameworks, and best practices, and integrate them into the product roadmap where beneficial.
• Continuous improvement: 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.
