I recommend Lemon to anyone looking for top-quality engineering talent. We previously worked with TopTal and many others, but Lemon gives us consistently incredible candidates.

FAQ about hiring Sinon developers

Where can I find Sinon developers?

You can find Sinon developers on popular searching platforms. Outline the job description (a web developer with unit testing experience with Sinon in this case), then post it on LinkedIn, Indeed, Glassdoor, or similar. If you’d like to search in a more specialized place, try going for a freelance platform or an agency. Also, many developers share their work and experience in developer communities and forums, like Stack Overflow and Github, so you might also find a fit there.

Apart from that, check out platforms like Lemon.io, which search for the best specialists, carefully test them, and then connect with businesses within 24-48 hours of submitting a request.

What is the no-risk trial period for hiring Sinon developers on Lemon.io?

A no-risk trial period for hiring Sinon developers on Lemon.io is a paid period (20 hours or less), which can help if it’s difficult to decide whether a developer is a good fit without actually seeing them perform real-life tasks. It’s also a nice option if you want to check if the developer gets along well with the existing team before actually signing up for a subscription.
If anything goes wrong at any point, though, we will also connect you with another developer who is a perfect fit for your project’s requirements.

Is there a high demand for Sinon developers?

Yes, there is a high demand for Sinon.js developers, and the library itself is pretty popular. Sinon helps to keep unit tests fast and deterministic by providing test spies, stubs, and mocks for easy mocking and verification of JavaScript function calls. Moreover, it can be easily integrated with the popular testing frameworks. Simon.js can be used pretty much on any project written with JavaScript, so numerous industries integrate it.

How quickly can I hire a Sinon developer through Lemon.io?

You can hire a Sinon.js developer through Lemon.io in under 48 hours! This is the time we need to hand-pick a few candidates that match your requirements perfectly. The only thing we need is a project description, and you’ll be connected with specialists whose skills with the technologies you are working with have already been checked by our tech interviewers. Of course, we also realize that it’s crucial for you to conduct your own interviewing and make sure that the candidates’ experience is what you’re looking for, so that might take a few more days.

What are the main strengths of Lemon.io’s platform?

The main strengths of Lemon.io’s platform are our careful matching process, which results in most clients hiring one of the 2 to 3 candidates we present them with, and the fact that we help save clients’ resources. That is possible because of the following factors:
1. All of the developers on the platform have 4+ years of experience and have been pre-vetted by our recruiters and trusted technical interviewers (they have already completed several projects with us and got excellent feedback).
2. We find top specialists on 300+ websites and other sources. Our community now has developers from over 50 countries in various time zones.
Moreover, for developers, being a part of the community is also quite advantageous, as they don’t have to take care of all the sales and administration tasks. Most importantly, they can work directly with ambitious startups from the USA and Western Europe without competing with hundreds of other applicants.
