Senior JavaScript developer job description template

You want your senior JavaScript developer job description to do three things: introduce candidates to your company’s culture and values, help them understand the role’s responsibilities, and get them excited about possibly working for your company!

You can use this template as a starting point and mix it up as you see fit.

Let’s start with the job title.

Job title

The job title is critical as it’s the first thing candidates see before reading your job description. To this end, keep the title short but informative. You want to capture a candidate’s attention. However, don’t make it too broad – like “JavaScript Developer” – as this will blend into the background.

How do you make it stand out on a job board? Add qualifiers like seniority level, type of developer (front-end, back-end, full-stack), and whether the role is full-time, part-time, or freelance. The role’s location (remote or office-based) is also worth mentioning.

For example, a good job title could be ” Full Stack Senior JavaScript Developer – Web Design – (Remote)”. In this example, the seniority level, type of development work, and location are all included.

Now that you’ve created your job title, it’s time for the next step. You want to craft your perfect senior JavaScript developer job description.

To make a positive first impression with your job description, showcase your company and what makes it a great workplace. Highlight your company’s culture, size, mission, goals, and perks. Also include benefits, office hours, and remote working options. Anything that sets your company apart from others.

At, we aim to stand out by injecting humor into our job descriptions. We believe that work should be fun and try to reflect that in our recruiting process. We’ll leave it up to you to decide if our approach is effective!

We believe that the current system for hiring and being hired as a software engineer isn’t working. For hirers, the process is long and time-intensive, typically requiring a developer from their team to pause their other work and manage technical vetting. On the other side, job seekers must wade through recruiter spam, repetitive interviews, code tests, and cryptic job descriptions just to answer the question: is this a job I want and would be good at?’s vetting and matching are designed and run by a team of developers passionate about fixing technical hiring. Each job posted to the platform is vetted by a senior developer, and each new job seeker who joins the platform has a 1-1 conversation with a member of the team so we can personally pitch them to clients they’d love.

  • You consider yourself to be a linchpin, not a cog.
  • You’re very nerdy about something. Star Wars, a particular subreddit, Web3, backyard chickens, famous guitar history, anything.
  • Career growth and financial success are core motivations for you.
  • You thrive in remote office environments.
  • You’re looking for a team culture that is curious, respectful, supportive, and at least once a day, hilarious.
