Role Overview

• You will work with the development team to build APIs, implement business logic, work with databases, integrate third-party services, and help ensure our applications are secure, reliable, and scalable.
• Training & Project Requirement: This role requires that the individual should have completed a relevant training. A personal or group project is acceptable following this — and even better, prior experience on a live project is considered an added advantage.

• Implement authentication, authorization, and access-control features.
• Help identify and fix backend bugs.
• Write clean, reusable, and maintainable code.
• Participate in code reviews and technical discussions.
• Write unit and integration tests for backend functionality.
• Assist with API documentation.
• Use Git and GitHub for source control and collaboration.
• Work with frontend developers to integrate APIs.
• Follow security and data-protection best practices.

Preferred Technical Skills

• Basic understanding of JavaScript and/or TypeScript.
• Familiarity with Node.js.
• Knowledge of backend frameworks such as NestJS, Express.js, or similar technologies.
• Basic understanding of SQL and relational databases.
• Familiarity with REST APIs and JSON.
• Basic understanding of authentication concepts such as JWT, sessions, and role-based access control.
• Familiarity with Git and GitHub.
• Understanding of HTTP methods, status codes, and client-server architecture.

Nice to Have

• Experience with PostgreSQL.
• Familiarity with Docker.
• Knowledge of Redis, queues, background jobs, or caching.
• Experience integrating payment, email, SMS, identity verification, or other external APIs.
• Basic understanding of cloud deployment.

What We Are Looking For

• Strong willingness to learn.
• Good problem-solving skills.
• Ability to understand technical requirements.
• Attention to detail.
• Ability to communicate problems clearly.
• Comfortable asking questions when requirements are unclear.
• Ability to work collaboratively with other developers and designers.
