Job Title: Backend Node.js Developer
Level: Mid / Senior (3–5 years experience)
Employment Type: Full-time(Remote)

Role Overview

We are looking for an independent, detail-oriented Backend Node.js Developer who writes clean, maintainable code, designs robust database structures, and knows how to optimize queries and background jobs for performance and reliability.

You will own server-side logic, database design, API integrations, and scheduled jobs/cron tasks that keep the system running smoothly.

Key Responsibilities

1. Backend Development & APIs

• Design, develop, and maintain RESTful (and/or GraphQL) APIs using Node.js (Express, NestJS, or similar).

• Implement business logic, data validation, and error handling in a clean, structured way.

• Ensure APIs are secure, reliable, and backward compatible where needed.

2. Database Design, Rules & Optimization

• Design and maintain database schemas (tables/collections, relationships, indexes).

• Implement database rules and constraints (foreign keys, unique constraints, validations) to maintain data integrity.

• Write efficient queries and stored logic where appropriate.

• Perform query optimization (indexes, query refactoring, avoiding N+1, caching strategies) to improve performance.

• Work with relational (e.g., PostgreSQL/MySQL) and/or NoSQL (e.g., MongoDB) databases as required.

3. Cron Jobs, Scheduling & Background Tasks

• Design and implement cron jobs and scheduled tasks (daily/weekly/monthly jobs, maintenance scripts, notifications, clean-ups).

• Manage background processing using job queues (e.g., BullMQ, Agenda, or similar).

• Monitor job executions, handle failures, and implement retries and alerting for critical jobs.

• Ensure that scheduled tasks and jobs are idempotent, fault-tolerant, and efficient.

4. Code Quality & Best Practices

• Write clean, modular, testable code following best practices and agreed coding standards.

• Maintain a clear project structure and separation of concerns (services, controllers, repositories, etc.).

• Participate in code reviews, refactor legacy code where needed, and help improve team standards.

• Effectively utilize SonarQube for code quality and security. 

• Add unit and integration tests for critical logic using tools like Jest, Mocha, or similar.

5. Performance, Security & Reliability

• Optimize backend performance (response time, throughput, memory usage).

• Implement security best practices: input validation, auth, rate limiting, OWASP considerations, secure storage of secrets.

• Use logging and monitoring tools to track system health and diagnose issues.

• Contribute to scaling strategies (horizontal scaling, database optimization, caching layers like Redis).

6. Independent Ownership & Collaboration

• Work independently on assigned modules/features, from design to deployment.

• Break down tasks, estimate work, and manage your own timelines effectively.

• Collaborate with frontend developers, product owners, and other stakeholders to clarify requirements.

• Provide technical input on architecture, trade-offs, and implementation choices.

Required Skills & Qualifications

Education

• Degree/Diploma in Computer Science, Software Engineering, IT, or equivalent hands-on experience.

Technical Skills

• 3–5 years of backend development experience, with strong proficiency in Node.js.

• Hands-on experience with one or more Node.js frameworks: Express, NestJS, Koa, etc.

• Strong understanding of relational databases (PostgreSQL/MySQL) and/or NoSQL (MongoDB).

• Experience with:

  • Database schema design and indexing strategies

  • Query optimization and performance tuning

  • Implementing cron jobs and scheduled tasks (node-cron, Bull, Agenda, or similar)

• Familiarity with Redis or other caching mechanisms is a plus.

• Experience with authentication & authorization (JWT, OAuth2, etc.).

• Comfort with Git and modern development workflows.

Soft Skills & Mindset

• Works well with minimal supervision, able to take a problem and drive it to completion.

• Strong sense of ownership and responsibility for stability and quality of backend services.

• Good communication skills; able to explain technical decisions clearly.

• Analytical thinker with a habit of documenting decisions and processes.

Nice-to-Have

• Experience with microservices or distributed systems.

• Experience with Docker and containerized deployments.

• Familiarity with CI/CD pipelines.

• Knowledge of message brokers (e.g., RabbitMQ, Kafka).

• Experience working in an agile/Scrum environment.
