Immediate Start! Back End Developer

Backend Developer

Backend Developer responsible for building and maintaining the server-side infrastructure. This includes managing data, building APIs, integrating with external services, and ensuring the backend can handle scaling, security, and performance optimally.

Job Overview :

As a Backend Developer, you will be responsible for developing, maintaining, and optimizing the server-side application, database systems, and integrations that power core functionalities. You will ensure the backend is efficient, secure, scalable, and maintainable, collaborating with the frontend team and other stakeholders.

Key Responsibilities :

1. API Development & Integration :

Design, develop, and maintain RESTful APIs and GraphQL services to serve data to the frontend.

Build and manage microservices for specific ERP functionalities (e.g., Inventory, Orders, User Management, etc.).

Integrate third-party APIs and services (payment gateways, authentication systems, etc.).

Work with API Gateway (AWS) to manage, monitor, and throttle API requests.

1. Database Design & Management :

Design and maintain PostgreSQL databases, ensuring data integrity, normalization, and efficient query performance.

Implement ORM (Object-Relational Mapping) solutions like Prisma, Sequelize, or Django ORM for easier database management.

Manage database migrations, backups, and high-availability configurations.

Design and implement caching mechanisms to improve database query performance (e.g., Redis).

1. Authentication & Authorization :

Implement secure user authentication and authorization systems (OAuth 2.0, JWT, Amazon Cognito).

Handle user sessions and roles to ensure that only authorized users can access specific data or perform actions.

1. Performance Optimization :

Optimize server-side performance to ensure the ERP system can handle high traffic and large data sets.

Perform database indexing and query optimization to reduce load times.

Set up and monitor auto-scaling infrastructure (e.g., AWS EC2 Auto Scaling, AWS Lambda for serverless functions).

1. Security & Compliance :

Implement best practices for securing the backend, including data encryption, rate limiting, and API security.

Ensure that sensitive data is stored and transmitted securely, using services like AWS KMS (Key Management Service).

Comply with industry standards for data protection and privacy (e.g., GDPR).

1. Testing & Debugging :

Write unit, integration, and API tests using testing frameworks like Jest, Mocha, or PyTest (depending on language).

Debug backend issues and optimize performance for a seamless user experience.

Conduct thorough testing for edge cases, system loads, and failure scenarios.

1. Collaboration & Agile Development :

Work closely with the frontend team to ensure smooth integration of APIs with the user interface.

Participate in agile development cycles, attending daily standups, sprint planning, and code reviews.

Contribute to architecture decisions and system design for scaling and maintaining the ERP platform.

1. Infrastructure & DevOps :

Manage cloud infrastructure, using AWS EC2, S3, Lambda, and other services.

Implement CI / CD pipelines for seamless deployment and updates using GitHub Actions, Jenkins, or AWS CodePipeline.

Use tools like Terraform or CloudFormation for infrastructure-as-code (IaC).

Node.js (JavaScript / TypeScript) or Python (Django / Flask).

Preferred Skills & Qualifications :

Familiarity with serverless architecture (AWS Lambda).

Experience with container orchestration tools like Kubernetes or Docker Swarm.

Experience with GraphQL and tools like Apollo Server for building GraphQL APIs.

Knowledge of monitoring and logging tools like AWS CloudWatch, Prometheus, or ELK Stack.

Familiarity with server-side rendering frameworks like Next.js (for full-stack development).

Advanced Database Management : Sharding, Replication, High Availability, and Failover mechanisms.

Education & Experience :

Degree or Experience in Computer Science, Software Engineering, or related field.

At least 6+ years of experience as a backend developer.

Proven experience in developing APIs, integrating with third-party services, and handling large-scale databases.

Soft Skills :

Strong problem-solving and analytical skills.

Excellent written and verbal communication skills.

Ability to work collaboratively in a team-oriented, agile environment.
