How to Outsource Freelance Ruby on Rails Experts

When it comes to Ruby on Rails developers outsourcing, the three vital factors you need to bear in mind are years of experience, hourly rate, and type of work arrangement. Besides, the scope of the project and your budget can also be the driving factor that decides who is the talent that fit your requirements.

To make your search easier, we collected information about places you can find RoR developers, approximate prices on their work, and how to prepare your job description. Let’s start with it.

Ruby on Rails Job Description

It’s important to write a clear Ruby on Rails job description if you want to attract proficient developers or development teams. It’s also vital to establish the right expectations upfront to streamline the vetting process and save everyone time and money.

What to Write in Ruby on Rails Developer Job Description?

An average job description includes the following parts: company introduction, job description itself, responsibilities, skills, and experience you’re expecting from your candidates. If your JD precisely describes the job position, and the pricing is average or higher than that on the market, chances are you’ll get lots of applicants. 

Company Introduction

Write 2-3 sentences describing your business in this section. Provide details on the company’s culture and benefits. This is an excellent place to provide a link to your business’s website. The finest applicants will conduct extensive research before their interview. 

Job Description

Be specific about the job you expect your new developer to complete.

Here is the sample job description:

‘‘We’re searching for a competent Ruby on Rails Developer to help us manage data transfer between our users and the server. You’ll be in charge of building and maintaining the core database’s server-side logic, as well as testing performance, troubleshooting, and integrating front-end aspects into the rails application’’.

Another example is

We need an experienced Rails developer to help us build a new eCommerce site. We need a fully developed web application with custom reports defined in the attached document.

The right developer will provide us with the full back-end and front-end code, and we will need you to deploy it to our production server. We will also need future improvements and enhancements with a maintenance contract after the website is fully developed and deployed. We’ve attached business requirements for your review.

The estimated duration of this project is three months. We need the completed app by XYZ date.”

It’s likely that most developers will have questions and want to discuss the project further, but this gives every developer a basic idea of what you’re looking for.

A good project description will help the developer give you a more accurate estimate and delivery date, so it’s one of the most important parts of finding the right developer and defining your project timeline.


Be clear and honest about the responsibilities. You can choose from the following tasks of the Ruby on Rails developer:

  • Design, develop, and maintain Ruby code that is efficient, reusable, and dependable.
  • Databases, key-value stores, blob stores, and other data storage methods may be integrated.
  • User-facing elements created by front-end developers are combined with server-side logic.
  • Identify bottlenecks and bugs, then come up with remedies.
  • Assist with code quality, structure, and automation’’.

How to write an effective Ruby on Rails job post

Your project description should give the developer a basic idea of what’s being built, and then define the deliverables that you expect.

For instance, do you want the developer to hand you the code and you’ll upload it to your production server?

Or do you want the developer to deploy the code for you? You might also want a maintenance contract for future bugs and improvements. The developer needs to know the time that will need to be spent on the project to give you a good estimate.

Below is a sample of how a project description may look. Keep in mind that many people use the term “job description” but a full job description is only needed for employees. When engaging a freelancer as an independent contractor, you typically just need a statement of work, job post, or any other document that describes the work to be done.

You can contact an experienced Ruby developer by selecting their profile if you think you’ve found a good fit. Once the terms for a project have been finalized, a client hires an RoR developer and pays the upfront fee.

Clients look through the site’s list of freelance developers and development companies by using its robust filter tools to find the right fit. You can filter developers based on their price range, body of work, and much more.
