Best sites to hire machine learning developers

Companies are throwing money into automating tasks and improving their workflows, so it’s no surprise that the demand for machine learning engineers has skyrocketed. This demand shows no signs of slowing.

However, knowing the best sites to hire machine learning developers with the skills you’re looking for can be a challenge. Where do you look? And what services do these platforms offer? There are so many questions and seemingly so few answers.

So, in this blog, we’ll provide nine of the best sites to hire machine learning developers for a project or as a permanent addition to your team. 

These sites vary in their approach. Some will do the legwork for you and match you with a suitable candidate (or candidates). Others will provide you with a list. The sites also cater to different timelines and budgets.

Without further ado, let’s jump to these sites and find out more!

Hire machine learning developers

We’ve broken this list of sites into different categories.

First up, we have the job boards. These can be the best sites to hire machine learning developers, but you’ll have to manage the hiring process. You basically post a job and wait for developers to apply.

Popular job boards include Glassdoor, Indeed, and ZipRecruiter. 

If you decide to go down the job board route, our machine learning software engineer job description template [LINK to article when it goes live] may help you.

Next, we have freelance marketplaces, including Upwork and Fiverr. These marketplaces let you connect with developers immediately. 

Freelance marketplaces can be an excellent choice if you have the time and confidence to interview candidates. However, you’ll have to handle all the hiring details yourself.

Finally, we have agencies like DevSpace and Agencies are excellent for companies who need help hiring but are short on time. However, they’re often more expensive.

Knowing which are the best sites to hire machine learning developers depends on your needs, so consider the following:

  • Your timeline and budget for hiring a machine learning developer
  • Your experience in hiring top machine learning developers
  • Your ability to test technical skills
  • The number of developers you need to hire
  • The level of expertise required for your machine learning developers

Let’s dig deeper.

Job boards

#1: Indeed

With over 250 million unique monthly visitors, Indeed is one of the biggest players in the job-hiring space. It operates in more than 60 countries and has been helping job seekers and companies since 2004. So let’s start by looking at its pricing. 


Free plans are available on Indeed, letting you post unlimited jobs. Paid subscriptions are also available. 

A paid subscription gives you various features, such as setting up alerts and reaching out to candidates. There are two types of subscriptions available – Standard and Professional:

  • Standard subscription: $120/month or $1,150/year
  • Professional subscription: $300/month or $2,880/year

What sets Indeed apart from most job boards is that it lets you search and view resumes for free. But when you find a candidate you want to contact, there’s a monthly fee. 

On the Standard subscription, you can contact up to 30 job seekers a month. However, you’ll need a Professional subscription to contact up to 100 candidates.

Contact credits get deducted from your subscription each time you contact a candidate. Each additional contact credit costs $3.

Optional pay-per-click (PPC) for job advertising is also available. Advertising means your job listings appear above free listings in Indeed’s search results. In other words, it’s like Google.

Indeed PPC starts at $5/day, and you can set your budgets. You’re charged per candidate application response. However, you only pay when people click on the job.

Pros and cons of Indeed

In terms of the best sites to hire machine learning developers, Indeed is a good place to start. It helps employers get their job listings in front of as many potential candidates as possible. The site also aggregates job postings from other job sites and cross-posts them.

You can also post unlimited jobs for free and view applicant resumes online. These features make it a strong choice for small businesses needing to hire quickly and cost-effectively. 

However, you may receive applications from candidates who have mass-applied for numerous jobs. This can make the hiring process lengthy and cumbersome. The applicant tracking tool is also limited, and subscribing to its add-ons can be expensive.

#2: Glassdoor

Founded in 2007, Glassdoor is an American site that lets current and former employees anonymously review their workplaces. 

Glassdoor is popular with employers who want to promote their company culture to job seekers. It’s also possible for companies to post jobs through this platform via Indeed. In 2020, Glassdoor and Indeed formed a partnership to streamline job postings.


Just like Indeed, a free plan is available on Glassdoor. This free plan lets you see employee insights, respond to reviews, and update your company information.

You can also upgrade to a custom-priced paid plan. Unlike Indeed, sponsored job ads are included in paid plans.You can expect to pay around just over $1,000/month for 21-50 job ads.

Pros and cons of Glassdoor

Glassdoor gives you a free company page. It also gives you branding features and the ability to manage reviews, and you can post an unlimited number of jobs on the free plan.

However, the free plan does not include branded job postings and job advertising, and no resume search tool is available. Additionally, the platform lacks an applicant tracking system (ATS). 

Finally, Glassdoor, unlike Indeed, does not provide a feature to search for resumes of passive job seekers and contact them.

#3: ZipRecruiter

ZipRecruiter is next in our list of the best sites to hire machine learning developers.

This platform has been a leading job board for over a decade, connecting more than 110 million job seekers with over 2.8 million businesses. The site’s AI-matching technology creates opportunities to connect employers and Angular developers.

You can use over 500 customizable templates to post a job on ZipRecruiter. The platform will then send the job opening to over 100 job sites. 

Its AI technology invites the most suitable candidates to apply, and you can auto-send pre-written messages to the best candidates. The platform also sends job alert emails and mobile notifications to candidates.


Pricing is straightforward and depends on the number of job postings needed. After a free trial, the Standard plan costs $16 per day per job, and the Premium plan costs $24 per day per job. 

Alternatively, you can pay a flat monthly rate for each job posting. This is helpful if you know your job could take a while to fill. 

The flat rates are as follows:

  • Standard plan – $299 per job per month
  • Premium plan – $419 per job per month
  • Pro plan – $719 per job per month
Pros and cons of ZipRecruiter

One of the best features of ZipRecruiter is its AI-matching technology. This tech can save you time and effort when hiring machine learning developers. 

Also, when you post a job on ZipRecruiter, the site posts it on over 100 job sites. This means you can receive applications within minutes of posting. You can also try the platform for free for four days and choose from hundreds of job templates.

Despite its advantages, ZipRecruiter may not be the best site to hire machine learning developers. Compared to Glassdoor and Indeed, ZipRecruiter offers fewer features, and it’s expensive for small businesses with just one job opening.

#4: MLConf

Machine Learning Conference (MLConf for short) has a free-to-post job board for companies interested in hiring machine learning developers. If you want to hire machine learning engineer talent through a job board, MLConf is a great place to start.


MLConf sponsors events across the US that help data science professionals meet, share new research, and swap ideas. As such, MLConf’s job board is a terrific place to find machine learning developers – and it’s completely free.

Pros and cons of MLconf

The MLConf community is growing through its bi-monthly newsletter, blog posts, interviews, and free meetups. As a result, there are lots of machine learning developers looking for jobs on their job board.

Job posts also remain active until you fill your positions.

However, MLConf doesn’t screen or vet applicants, so you may receive applications from candidates who’ve mass-applied for numerous jobs – just like on Indeed. This lack of screening can make the hiring process lengthy and cumbersome. 

Freelance marketplaces

#5: Upwork

Upwork is one of the best sites to hire machine learning developers. It boasts millions of freelancers and thousands of active jobs. 

The site lets you hire machine learning developers for simple coding tasks or full-suite projects. To get started, you provide details about your project and say whether it’s a part-time, contractual, or full-time opportunity. 

Next, you’ll receive proposals. You can then screen, vet, and interview candidates to ensure they’re the right fit.


With Upwork’s Client Marketplace plan, you pay a 5% fee on all payments. So, for example, if your payment is $100, you’ll be charged an additional $5 by Upwork. 

However, eligible clients in the U.S. who pay with a checking account can enjoy a discounted rate of 3%. In this case, you’ll only pay an additional $3 for a $100 payment.

Under the Client Marketplace plan, features include:

  • Access to Upwork’s Rising Talent, Top Rated, and Top Rated Plus freelancers
  • Inviting up to 30 freelancers to your job
  • Extra reporting options

Also, you only have to pay a fee when making payments instead of a monthly subscription cost.

Pros and cons of Upwork

Because of Upwork’s vast network, you’ve got thousands of machine learning developers to choose from. The hiring process is also entirely in your hands. 

These two points are both pros and cons.

While Upwork is an excellent option for hiring machine learning developers on a budget, hiring can be time-consuming. It also requires a basic understanding of the role you’re hiring for. This is because you’re responsible for the entire process, including interviewing and vetting candidates.

#5: Fiverr

Fiverr is a marketplace that provides freelance services at a minimum cost of $5.00 per project. In addition, it lets employers connect with machine learning developers from around the world.


Freelancers set their pricing. Their “gigs” range between $5.00 and $995.00 per project, and the freelancer keeps 80% of each transaction.

When you place an order to work with a freelance machine learning developer, you pay Fiverr the gig price plus a 5% service fee. The minimum service fee is $2.

Fiverr holds your payment until the freelancer completes the work. Once complete, the freelancer gets paid. The website administrators provide support in case of a dispute or incomplete order.

Pros and cons of Fiverr

Just like Upwork, Fiverr seems like an obvious choice when answering the question of the best site to hire machine learning developers. You’ll have thousands of talented developers to choose from. However, there will be duds. Because the entire hiring process is in your hands, you need to know your stuff to find qualified freelancers. 

While customer support can resolve disputes, Fiverr won’t refund you if a freelancer doesn’t have the skills you’re after. 


With millions of vetted candidates, Hired is right up there with Upwork as one of the largest marketplaces for hiring developers. 

Hired helps employers find engineers through its custom-matching software. The platform offers a range of features that lets employers create a company profile, search for candidates using their search algorithm, and request interviews with candidates.


With Hired, two pricing options are available. 

The first option is Pay Per Hire. This option is for employers who need flexibility, costing 15% of the first-year base salary per hire. 

The second option is Unlimited Hiring. This option is a custom annual subscription for teams that want predictability. Employers pay a fixed yearly fee for unlimited hiring and premium customer support.

Pros and cons of

Hired’s search algorithm matches you with a pool of developers and eliminates gender and racial identifiers to ensure fair hiring. This matching means you can select a developer based solely on their technical skills and experience.

You can also send customized assessments to potential hires for free and run programming challenges in real-time or asynchronously. Challenges like this with a complete coding playback let you see how the devs work.

However, employers must still have some technical experience to send customized assessments to candidates. This assessment stage is a crucial step in the hiring process. It’s also unclear how much an annual subscription would cost a company. Again, prices are customized, and employers must apply for a demo to learn more.


#8: is an agency that uses an AI-powered agile process to connect businesses with development teams. They work with companies that want to avoid handling product development themselves.

To do this, they can tap into their network of machine learning developers to help you with your project. They’ve got something for everyone.


Pricing varies from project to project, depending on the scope.

Pros and cons of DevTeam

DevTeam has a rigorous screening, vetting, and testing process to identify developers with skills. The site also lets you request experts who specialize in specific machine learning tools, meaning you can find developers for most tasks.

However, their pricing isn’t disclosed on-site, and exactly how they match machine learning developers to jobs is unclear.
