Senior Backend Developer Job Summary:
The Senior Backend Developer will lead the design, development, and optimization of server-side architecture, APIs, and data systems that power our digital products. 

This role demands a strong technical foundation, strategic thinking, and leadership capabilities to ensure the backend infrastructure is robust, scalable, secure, and aligned with business goals.

With 2+ years of hands-on experience, the ideal candidate will take ownership of backend development initiatives, mentor junior developers, and collaborate closely with cross-functional teams including product managers, frontend engineers, and DevOps. The role involves translating complex business requirements into efficient backend solutions, driving performance improvements, and ensuring high availability and reliability of services.

The Senior Backend Developer will also play a key role in setting coding standards, reviewing code, and contributing to architectural decisions that shape the future of our technology stack. A proactive mindset, strong problem-solving skills, and a passion for clean, maintainable code are essential.

Key Responsibilities:
Architect and Develop Scalable Backend Systems:Design, build, and maintain robust server-side applications and APIs that support high-performance, scalable, and secure digital products. 

Cloud-Native Development & Deployment:Leverage cloud platforms (e.g., AWS, Azure, GCP) to architect and deploy backend services using modern cloud-native practices such as containerization (Docker), orchestration (Kubernetes), and serverless computing. 

Database Design & Management:Integrate and manage relational and NoSQL databases (e.g., PostgreSQL, MongoDB, DynamoDB), ensuring data integrity, performance optimization, and scalability. 

API Design & Integration:Develop RESTful and GraphQL APIs with a focus on clean architecture, versioning, and documentation. Ensure seamless integration with frontend and third-party services.

Security & Reliability:Implement best practices for authentication, authorization, data protection, and secure coding. Ensure high availability and fault tolerance across backend systems.

Performance Optimization:Continuously monitor and improve application performance through profiling, caching strategies, and load balancing.

AI/LLM Integration (Preferred):Collaborate with data science and AI teams to integrate machine learning models or large language models (LLMs) into backend workflows, enabling intelligent features and automation.

Leadership & Mentorship:Lead backend development initiatives, mentor junior developers, conduct code reviews, and contribute to technical decision-making and architectural planning.

Cross-Functional Collaboration:Work closely with frontend developers, DevOps engineers, product managers, and QA teams to ensure smooth end-to-end delivery of features and enhancements.

System Maintenance & Continuous Improvement:Troubleshoot, debug, and upgrade existing systems. Drive continuous improvement through refactoring, automation, and adoption of emerging technologies.

Documentation & Knowledge Sharing:Maintain clear and comprehensive technical documentation. Share knowledge and promote best practices across the engineering team. Required Skills:

Technical Proficiency

• Expertise in backend programming languages such as Node.js, Java, Python, or Go, with the ability to write clean, maintainable, and efficient code.
• Strong experience with database technologies, including relational (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis), with a solid understanding of data modeling, indexing, and performance tuning.
• Proficient in designing and consuming RESTful APIs, and familiar with GraphQL and microservices architecture.
• Hands-on experience with message queues and event-driven systems (e.g., Kafka, RabbitMQ) for building scalable and decoupled services.
• Deep understanding of authentication, authorization, and security best practices, including OAuth, JWT, and data encryption.

Cloud & DevOps Skills

• Cloud platform experience (AWS, Azure, or GCP), including deploying and managing backend services using containers (Docker), orchestration tools (Kubernetes), and serverless functions.
• CI/CD pipeline knowledge, with experience in automated testing, integration, and deployment using tools like Jenkins, GitHub Actions, or GitLab CI.

Leadership & Collaboration

• Proven ability to lead backend development efforts, including planning, task delegation, and code reviews.
• Mentorship experience, guiding junior developers and fostering a collaborative, high-performance engineering culture.
• Strong cross-functional collaboration skills, working effectively with frontend developers, DevOps engineers, product managers, and QA teams.

AI/LLM Integration (Preferred)

• Exposure to AI/ML workflows or LLM integration, supporting intelligent features such as recommendation engines, chatbots, or automated decision systems.

Soft Skills

• Excellent problem-solving and debugging skills, with a proactive approach to identifying and resolving performance bottlenecks and system issues.
• Effective communication and presentation abilities, capable of articulating technical concepts to non-technical stakeholders.
• Adaptability and continuous learning mindset, staying current with backend technologies, frameworks, and industry trends.

Professional Experience

• 2–5 years of hands-on experience in backend or server-side development, with a track record of delivering scalable and secure applications.
• A strong portfolio or GitHub profile demonstrating real-world projects, architectural contributions, and leadership in backend development.
