Hire Node.js developers pre-screened for technical and cultural fit

Node.JS is an open-source JavaScript runtime environment built on and to be used with the JavaScript programming language. Because it's open-source, it's free and easily accessible to the general public. It's a full-stack, cross-platform runtime environment that can be used to develop client-side and server-side components of an application or website. With so many frameworks and environments, you may wonder why to choose Node.JS over others.

There are many advantages to working with a Node.JS developer. For example, Node.JS developers can build effective, scalable, and cross-platform applications. Node.JS has grown in popularity since its release in 2009 and is expected to remain competitive. Node.JS has many advantages over other platforms, and some of the leading enterprises and organizations use Node.JS, including YouTube, NASA, Reddit, Twitter, and Netflix.

However, finding and hiring a Node.JS developer can be challenging. Supply and demand pose significant challenges, making the quest for Node.JS developers even more difficult. Understanding what Node.JS is, how to create an effective job description, and what interview questions to ask can help.

What Is Node.JS?

Node.JS is a Chrome-built, JavaScript-based runtime platform that allows developers to create quick and scalable network applications. It's lightweight, efficient, and operates on an event-driven, nonblocking I/O model. It's cross-platform and can work in various environments, including Windows, Linux, and macOS. Though a back-end environment, it can create back-end and front-end applications. It operates on JavaScript's V8 engine.

Node.JS can create dynamic page content; collect form data; add, delete, and modify data in your database; and create, open, read, write, delete, and close files on specific servers. Its primary functions are to develop websites and back-end API services. Node.JS can also be used to build streaming web applications, real-time collaboration tools, real-time chat applications, and more.

What Does a Node.JS Developer Do?

Node.JS developers are responsible for creating logic for server-side web applications, usually through JavaScript. However, variants, such as CoffeeScript, can also be used. Developers using Node.JS create back-end features and collaborate with front-end developers to integrate their work within Node.JS applications.

Other responsibilities include:

• Crafting reusable and testable code
• Designing and executing low-latency, highly available, and performative applications
• Creating and implementing security and data protection
• Integrating data storage solutions

Because Node.JS is based on JavaScript, developers should be proficient in it.

While Node.JS developers in Latin American countries are equally skilled, the lower cost of living means they’re usually paid 30%-50% less than their US counterparts, with salaries varying based on location and experience. Revelo provides a cost-effective solution while offering highly qualified, pre-vetted Latin American developers.

How to Write a Job Description for Node.JS Developers

A well-written job description can help you pull in the best developers for your team. Be sure to include basic information, such as the job title and a clear description of the responsibilities you expect from your candidates. Laying this information out can help avoid confusion and miscommunication between you and your candidates and help ensure that your candidates’ vision and goals align with yours.  

Additionally, consider the following when writing a job description:

• Education and experience: A Node.JS developer should have a certificate or bachelor’s or master’s degree in computer science or a similar field. Alternatively, a Node.JS developer can have relevant industry experience. If your candidate lacks an education, ensure they have at least five years of experience.
• Qualifications and skills: Since Node.JS is based on JavaScript, candidates should have experience and familiarity with the JavaScript language. They should also be well-versed in API communications and database management.
• Benefits: Outline any benefits that your company offers to employees. This could include health benefits, life insurance, 401(k) and pension, and paid time off, including personal, sick, and vacation days. If you want to offer further benefits to attract candidates, consider offering remote or hybrid work.

To write an effective job description, consider the following:

• Addressing candidates directly
• Choosing a clear and concise job title
• Writing an honest blurb about your company
• Listing out the role's responsibilities in a clear and obvious way
• Ensuring that required experience and education are listed
• Highlighting attractive benefits

You should also figure out what seniority of developer you want to hire. Each level will have different experiences, educational backgrounds, and responsibilities. You can opt for a junior-level developer if your project requires less experience and skills. If your job requires more extensive knowledge and a proven track record working with Node.JS, then hiring an intermediate or senior-level developer is better.

Interview Questions for Node.JS Developers

Knowing what interview questions to ask, why you're asking them, and what answers to expect can help you search for proficient Node.JS developers.

Below are broad yet essential questions to ask but should not be the only ones you ask potential candidates. In addition, ask them more in-depth Node.js interview questions that cover their background, education, experience, and technical and soft skills.

What is Node.JS?

Asking this fundamental question ensures that your candidates are familiar with the platform you're hiring for. You should expect your candidates to answer this question clearly and concisely. They should be able to explain what Node.JS is and its use. They may also go the extra mile explaining Node.JS features and what sets it apart from similar platforms. Finally, your candidates may also explain why Node.JS is used and give real-world examples of when it has been used.

Explain the differences between back-end and front-end development

Anyone working in development should know how to answer this question. Asking them to explain the differences will allow you to assess a candidate's knowledge and familiarity with both types of development. Candidates should be able to explain what differentiates the two development styles, how each is used, and what each is used for, with examples.

What databases can be used with Node.JS?

Asking this question allows you to further gauge a candidate's knowledge of Node.JS. There are many databases out there, but some are more commonly used with Node.JS than others. For example, MongoDB is a database widely used with Node.JS; other answers may include MySQL and PostgreSQL.
