Node.js Developer - Server Side Component (5-10 yrs)

The - Senior Node.js Developer job description outlines the key responsibilities and requirements for a mid-to-senior level software development position that primarily focuses on back-end development using Node.js.

A candidate for this role is expected to have 5-12 years of hands-on experience, demonstrating proficiency in Node.js and related technologies, and be capable of handling complex tasks related to server-side development, performance optimization, and system integration.

Job Overview :

The Senior Node.js Developer will be responsible for creating and maintaining the server-side logic that powers web applications. These server-side components handle requests from the front-end, perform necessary computations, interact with databases, and send back responses.

The role also includes ensuring that the server-side infrastructure can handle a high load and function smoothly at scale. Collaboration with front-end developers is essential to ensure seamless integration between the client-side and server-side components of the application.

Key Responsibilities :

1. Develop and Maintain Server-Side Components :

- The developer will create and maintain the essential back-end components that handle data processing, authentication, and any business logic that needs to be executed on the server.

- This is crucial for ensuring that the application functions effectively and reliably.

2. Ensure Optimal Performance :

- A major part of the role is to ensure that the back-end infrastructure is optimized for high performance.

- This includes optimizing how data is fetched from the database, how API requests are processed, and how the server responds to requests quickly, even under high traffic.

3. Collaboration with Front-End Developers :

- As a Node.js developer, one of the primary responsibilities is to collaborate with front-end developers.

- The integration of user-facing elements, which include HTML, CSS, and JavaScript, with back-end logic, such as APIs and databases, is essential to provide a seamless user experience.

4. Write Reusable, Testable, and Efficient Code :

- The candidate is expected to write clean and maintainable code that can be reused across the application and is easily testable.

- Writing testable code is crucial in maintaining the quality and robustness of the application, reducing the risk of bugs.

5. Security Protocols and Data Protection :

- Security is an important aspect of server-side development.

- The developer will be tasked with implementing security measures to protect user data, such as encryption, access controls, and secure data storage practices. Ensuring that the application is secure against vulnerabilities like SQL injection or cross-site scripting (XSS) is critical.

6. Debugging and Performance Optimization :

- Debugging is an integral part of any development role.

- The Senior Node.js Developer will be responsible for troubleshooting issues that arise in production and ensuring that performance bottlenecks are identified and resolved.

- This includes optimizing code to handle large-scale data efficiently and ensuring that server requests are handled smoothly.

Requirements :

1. Proven Experience as a Node.js Developer :

- The ideal candidate should have 5-8 years of experience specifically working with Node.js or in a similar back-end development role.

- This experience should encompass the full software development life cycle, from coding to testing and deployment.

2. Strong Knowledge of JavaScript and Node.js Frameworks :

- Since Node.js is based on JavaScript, a deep understanding of both JavaScript fundamentals and advanced concepts is required.

- Familiarity with popular frameworks like - Express.js- , which simplifies the development of web applications, is also essential.

3. Experience with RESTful APIs and Web Services :

- Node.js is commonly used to build RESTful APIs that allow communication between the front-end and back-end of applications.

- Understanding how to design and implement RESTful APIs is a core skill.

4. Familiarity with Database Technologies :

- The developer should be comfortable working with databases such as - MongoDB- (NoSQL), - MySQL- , or - PostgreSQL- (relational).

- The candidate should be able to design efficient database schemas and write optimized queries to fetch and manipulate data.

5. Problem-Solving Skills :

- Strong analytical and problem-solving skills are crucial to this role.

- The developer must be able to think critically to solve complex coding challenges, ensuring that the code is efficient, scalable, and robust.

6. Bachelor's Degree in Computer Science or Related Field :

- A formal education in computer science, software engineering, or a related field provides a strong foundation in the theoretical aspects of programming, algorithms, and data structures, which is important for the role.
