Clearly define the role

Creating a spot-on job description for a JavaScript developer role starts with understanding the nuances of the job you're hiring for. First, clearly define what this developer will do in your organization. Will they focus on front-end development, backend, or full-stack?

Collaborate with your technical team

Next, work with your technical team to list the specific technologies the developer should be proficient in. For JavaScript roles, you might require expertise in frameworks like React, Angular, or Vue.js. Also, mention the developer tools they should be familiar with, like Node.js or Webpack.

Divide skills into must-haves and nice-to-haves

For the skills section, segregate them into "must-haves" and "nice-to-haves." Must-haves could be core JavaScript knowledge, experience with RESTful APIs, and version control using Git. Nice-to-haves might include experience with GraphQL, mobile app development, or familiarity with cloud services like AWS.

Emphasize valued soft skills

Be explicit about the soft skills you value. Communication, teamwork, and problem-solving skills are usually key for any developer role.

Showcase unique aspects of your company

To make sure you're attracting top-tier talent, highlight the unique aspects of the role and your company. Are there professional growth opportunities? Are you using cutting-edge tech stacks? Sharing these perks can pique the interest of top candidates.

Keep your job description up-to-date and compliant

Remember to ensure that your job description is up-to-date, free from discriminatory language, and compliant with legal regulations. Below, we've created a job description template you can use as the basis of your JavaScript developer job post.

Creating a JavaScript developer job description involves striking a balance – detailed yet concise, specific but not restrictive. Let's go over five common pitfalls to steer clear of.

5 things to avoid when writing a javascript developer job description graphic
  1. Using jargon: Avoid heavy use of technical lingo. You don't want to scare off good candidates who might not yet be familiar with every acronym.

  2. Being too vague or too specific: Vague descriptions attract inexperienced or unqualified candidates, while being overly detailed with an abundance of requirements may overwhelm and deter qualified applicants.

  3. Ignoring soft skills: It can be too easy to focus on technical abilities and neglect qualities like teamwork or communication skills.

  4. Non-inclusive language: Ensure your description is free from gendered terms and other discriminatory language. You want to be open to a diverse candidate pool.

  5. Outdated requirements: JavaScript frameworks and tools evolve. Make sure you're not asking for experience in outdated technologies, unless necessary for the role.
