How to write a Ruby developer job description

How to write a ruby developer job description featured image

Hiring the best Ruby developer is key to ensuring your company’s web apps work smoothly. Without a knowledgeable and skilled developer, you run the risk of downtime and outages that frustrate employees and turn away customers. So it’s crucial to hire a Ruby developer who knows this programming language inside and out.

The process of hiring a Ruby developer starts with writing a great job description. It should clearly describe who you want to hire and why they’d want to work for your company.

In this guide, we’ll explain how to write a compelling Ruby developer job description and share a template you can use to kickstart your hiring process.

What is a Ruby developer?

A Ruby developer is a programmer who is highly proficient in the Ruby coding language. Ruby is commonly used for building web apps and static websites, scripting, and automating software processes.

Ruby is also the coding language used for the popular Ruby on Rails web application framework. A Ruby developer can help your company build new web apps using Ruby on Rails or maintain existing apps.

Key skills to look for in Ruby developers

Look for these skills when hiring a Ruby developer:

  • Ruby proficiency: Candidates should have a deep understanding of and experience using the Ruby programming language. 

  • Ruby on Rails experience: Ruby on Rails is based on Ruby and is used for many web apps, so having a developer with Ruby on Rails experience can expand your business’s capabilities.

  • HTML and CSS competency: HTML and CSS are used alongside Ruby for many static websites. Competency in these programming languages can help your developer work more efficiently.

  • Collaboration: The developer you hire should have strong collaboration skills to work smoothly with the rest of your development team and project managers.

  • Time management: Candidates must be able to manage multiple projects and stay ahead of deadlines for launching web apps or introducing new features.

How to write an effective Ruby developer job description

Your Ruby developer job description should describe the developer you want to hire and persuade candidates to work for your company.

Describe your ideal Ruby developer

Your job description should explain exactly what you’re looking for in a Ruby developer. That includes discussing not only the programming skills you expect them to have but also the soft skills they should bring to the job.

For example, if the developer you want to hire will join an existing team of developers, you can highlight collaboration and communication as skills you’re looking for in a candidate.

The more detailed you can be in this part of your job description, the more likely it is that you’ll attract applicants who will be a good fit for your company.

Highlight the benefits of working for your company

Your job description also needs to persuade Ruby developers that they should work for your company instead of competitors. You should highlight not just the salary you can offer, but also non-monetary benefits like time off, remote or hybrid work, a great company culture, and more.

It’s also a good idea to discuss your company’s mission. Ruby developers who share your company’s values are more likely to apply for your role and to remain with your company for the long term if hired.

Ruby developer job description template

Here’s a simple job description template you can use to hire a Ruby developer:

Ruby developer job description template

Company introduction

Your job description should start out by introducing your company, including when it was founded, what markets you serve, and whether you have won any industry or business awards. You can also highlight your company’s mission here.

Additionally, your introduction should mention how Ruby programming has contributed to your business’s success and how you see a Ruby developer unlocking more potential.

Benefits of working with [your company]

After you introduce your company, your job description should highlight what makes it special.

List the benefits you offer all employees as well as any optional benefits (e.g. remote work) that a Ruby developer could receive. This is a good place to briefly describe how much paid time off your company offers and whether your role includes benefits like health insurance and matched retirement contributions.

2 things to avoid when writing a job description for Ruby developers

Introducing bias into your job description

A Ruby developer job description that uses biased language can result in a smaller and less diverse applicant pool. It can also put you on the wrong side of employment discrimination laws and result in costly lawsuits.

Gendered phrases are one of the most common ways that bias is introduced into job descriptions. Avoid male-coded phrases like “aggressive” or “competitive,” which can discourage women from applying for your role.

It’s also important to avoid ageist phrases like “young” or “digital native,” which can introduce bias against older applicants.

Leaving out soft skills

While the bulk of a Ruby developer’s work will depend on their coding proficiency, soft skills like collaboration, communication, and time management are still essential to a candidate’s success.

Developers often collaborate within small teams and need to work closely with project managers to deliver a functioning app. They may also have multiple competing projects and need to be able to prioritize effectively to meet deadlines.

Next steps: Attracting and assessing Ruby developer candidates

Once you have a polished Ruby developer job description, you can post it on online job boards to start soliciting applications. Working with a recruiter or advertising your job description on social media can help you attract even more qualified developers.

Is a Ruby developer the same as a Ruby on Rails developer?

Ruby is a general-purpose programming language, while Ruby on Rails is a web app framework built using the Ruby language. Many Ruby developers have experience with it, but not all. You can use TestGorilla’s Ruby on Rails skills test to evaluate candidates’ proficiency in this area.

How many years of experience should a Ruby developer have?

A Ruby developer may only need one to two years of experience to take on most projects. This programming language is designed to have a gentle learning curve. That said, unique web apps or projects that require additional programming languages like Javascript may require a developer with more experience.
