Back End Developer

We are looking for an experienced and highly analytical Backend Developer to design, build, and maintain scalable and robust systems. The successful candidate will possess in-depth knowledge of system design, API creation, and database schema development, with a strong understanding of deployment and DevOps principles.

Primary Tech Stack:

• Backend:

  Node.js, Express.js, RESTful APIs, Microservices, Serverless Architectures, Event-Driven Architectures, GraphQL, WebSockets

• DevOps:

  AWS (EC2, Lambda, S3, RDS, DynamoDB), GitHub Actions, CI/CD Pipelines, Docker

• Databases:

  PostgreSQL, MongoDB, Redis, Cassandra

• Testing:

  Jest, Unit Testing, Integration Testing, End-to-End Testing

Responsibilities:

• Design, develop, and maintain efficient, reusable, and reliable backend systems with a focus on high availability, fault tolerance, and scalability.
• Create well-documented and scalable APIs (RESTful, GraphQL) and optimize database schemas for performance and data integrity.
• Ensure the best possible performance, quality, and responsiveness of applications through profiling, monitoring, and optimization techniques.
• Implement robust security and data protection measures, including authentication, authorization, encryption, and vulnerability management.
• Collaborate with frontend developers and other stakeholders to integrate user-facing elements with server-side logic and ensure seamless data flow.
• Participate in rigorous code reviews, adhere to coding standards, and maintain high code quality through continuous refactoring and testing.
• Contribute to all phases of the development lifecycle, including requirements gathering, architectural design, development, testing, deployment (CI/CD), and post-launch maintenance and support.
• Have an understanding of deployment strategies (blue/green, canary), server management (Linux, container orchestration), and infrastructure as code (IaC) principles.

Requirements:

• Proven experience (5+ years) in building scalable, high-performance, and resilient backend systems.
• In-depth knowledge of system design principles (e.g., SOLID, DRY, Twelve-Factor App) and architectural patterns (e.g., Microservices, Event Sourcing, Domain-Driven Design).
• Strong proficiency in at least one backend programming language (e.g., Python, Node.js) with a deep understanding of its ecosystem and best practices.
• Extensive experience with designing and implementing RESTful APIs, including versioning, pagination, and error handling.
• Solid understanding of relational (e.g., PostgreSQL, MySQL) and/or NoSQL (e.g., MongoDB, Cassandra, Redis) database systems, including advanced querying, indexing, and optimization.
• Experience with cloud platforms (e.g., AWS, GCP), including compute, storage, networking, and managed services.
• Familiarity with containerization and orchestration tools (e.g., Docker, Kubernetes) and their application in production environments.
• Understanding of DevOps practices and principles, including CI/CD pipeline setup and management, infrastructure automation, and monitoring tools (e.g., Prometheus, Grafana).
• Excellent problem-solving, analytical, and communication skills, with the ability to articulate complex technical concepts to both technical and non-technical stakeholders.
