Businesses in just about every industry are using machine learning to innovate, boost productivity, and lower costs. It's helping companies improve customer relations, automate key practices, and scale at a rapid rate. Smart business leaders are joining the trend by hiring experience machine learning engineers to lead up their machine learning efforts.

Of course, it isn’t always easy finding a great team of machine learning engineers. It can be challenging to find people with the right experience or even the right set of complementary soft skills needed to seamlessly integrate into your business and work effectively with your current employees.

Assembling the right team takes time, patience, and a clear set of benchmarks. This article will lay out strategies for creating a top-of-the-line machine learning engineering staff. You’ll learn how to locate the best engineers and how to get them to join your team. You’ll also learn how to define their roles and what kinds of salaries you should be paying them.

What Is Machine Learning?

Machine learning is a broad term that refers to automating computer processes and building algorithms that can make decisions on their own. It can be applied to just about every sector in today’s economy, from construction to public transportation.

You've likely interacted with machine learning without being aware. In online retail, for example, machine learning powers chatbots that help customers make decisions about their purchases. Machine learning tools can also help businesses make accurate predictions about consumer tastes and behaviors. Platforms like Spotify and Netflix likewise use machine learning algorithms make predictions about what kind of entertainment you might enjoy.

Machine learning has found application in the industrial sector, too. It's being used to track supplies and make predictions about when and where inventory will be needed. It also helps plan when maintenance and repairs need to be carried out so that businesses don’t experience unplanned downtime.

What Do Machine Learning Engineers Do?

It may help to think of machine learning engineers as being both data scientists and computer programmers at once. The best machine learning engineers have a bent for statistics and a passion for data. They combine that with technical skills to build machine learning models that can analyze data, identify patterns, and create accurate predictions.

As was mentioned, machine learning engineers create the bots on websites that chat with customers, answer questions, and collect information. They also build machine learning models, which are algorithms designed to look for patterns in data. These models sift through mountains of data to come up with the most important information.

Machine learning engineers' essential duties usually include:

  • Planning, implementing, and overseeing the operations of machine learning models
  • Carrying out data-based analysis based on the needs of your business
  • Fine-tuning existing machine learning algorithms to better suit the changing needs of your business
  • Reporting to the stakeholders in your business about the results of their machine learning experiments
  • Coordinating with stakeholders to plan and refine your company’s machine learning strategy

In many cases, they act as a bridge between your company’s technical and non-technical staff. They can help assess exactly where machine learning tools might improve your business, make sure those tools are implemented correctly, and maintain clear lines of communication with stakeholders to ensure that the project is accomplishing its goals.

What Are the Key Machine Learning Roles?

Before you begin the process of hiring, you’ll need to have a solid understanding of the different positions on a typical machine learning team. Here are some of the most common machine learning roles:

Data Analysts

Data analysts are at the front lines of machine learning. They take data and mine it for insights into just about anything, from consumer behavior to traffic patterns.

A good data analyst will have experience working with a few different computer languages. They’ll also be familiar with data visualization tools. Most data analysts have a background in statistics, though they may also have a specialty in a particular business niche like marketing or risk analysis.

Data Engineers

This role is primarily geared towards building the infrastructure that allows analysts to do their job. Data engineers handle capturing, storing, and processing data so that it can be accessed and analyzed.

They should be experienced working with tools that manage large volumes of data, like Hadoop or Spark. They should also be familiar with managing data structures and algorithms as well as overseeing ETL projects.

Data Scientists

Data science has some overlap with data analysis since both involve analyzing and interpreting data. However, data scientists also work closely with other members of your business by sharing their data-driven insights. This means that data scientists need to have all the technical skills that data analysts possess — but data scientists also need strong soft skills like verbal and written communication skills.

Data scientists are often responsible for building ML algorithms that can analyze patterns in data. In addition to their other technical skills, data scientists need to know how to use Python and SQL. Like data analysts, they should have a strong foundation in statistics.

Research Scientists

These are responsible for staying current with the very latest developments in machine learning and artificial intelligence so that they can implement new tools whenever they might benefit your business. Research scientists may have more formal education in computer science than other machine learning professionals possess. A good research scientist is also familiar with areas on the cutting edge of machine learning like Computer Vision or Natural Language Processing (NLP).

It’s worth noting that not every business needs to employ a research scientist. If your company is in the tech sector, it’s probably useful to have someone on staff who has their finger on the pulse of latest developments. If your competitors are using the latest technology and leaving you behind, then it might be worth your while to hire a research scientist so that you can catch up with them or even overtake them.

Machine Learning Engineers

Data scientists usually work very closely with machine learning engineers to build and update machine learning models. Machine learning engineers don’t just focus on one model — they're concerned with the overarching machine learning infrastructure and its role in your business.

A good machine learning engineer will have experience using cloud services and deployment tools like Cortex and PastAPI. They'll also be familiar with data orchestration tools like Kubernetes and different deployment strategies.

What Is a Typical Machine Learning Engineer Salary?

Machine learning engineers earn different salaries based on their locations. That’s why many businesses choose to hire remote engineers based abroad.

Machine Learning Engineering Salaries in the United States

The average annual salary of US machine learning engineer is $157,007.

That figure will change depending on your exact location, of course. The average annual salary of a US machine learning engineer living in New York City is $186,862. In Cupertino, CA, the average machine learning engineer can earn $182,962. also notes that many machine learning engineers based in the United States earn benefits like health insurance, dental and vision insurance, 401K, and gym memberships. Where relevant, machine learning engineers may be eligible for relocation expenses and other perks.

Machine Learning Engineering Salaries in Eastern Europe

Workers in Eastern Europe often earn less than those in the United States or Western Europe. In Romania, for example, the average machine learning engineer earns about RON 79200 or $17,222.

In Poland, the average machine learning engineer earns more than in Romania, but still significantly less than they might in the United States. They typically bring home PLN 136668, or the equivalent of $32,880 U.S. dollars.

Machine Learning Engineering Salaries in Latin America

Machine learning engineers earn lower salaries in Latin America, largely because the cost of living is much lower than it is in the United States. In Brazil, for example, the average annual cost to hire senior Brazilian machine learning engineers is around $99,692.

In Colombia, the average annual cost to hire senior Colombian machine learning engineer is around $101,264.

And in Chile, the average annual cost to hire a senior Chilean machine learning engineer is approximately $106,960.

Where to Find Machine Learning Engineers

Once you’ve determined the machine learning positions that you need to fill, it’s time to start assembling your team. Here are some of the best ways to find experienced machine learning engineers for your team.

Job Boards

As old fashioned as it may sound, job boards can still be an effective means of recruiting engineers to join your business. Be aware that job boards are probably more geared at recruiting younger, less experienced engineers. If you’re looking for relatively junior staff members to fill entry-level roles like data analyst, then a job board may be a good place for you to start. If, however, you’re looking for more senior staff, you may need to use a different approach.

If you do choose to use job boards, be sure to use specialized boards. Generalist job sites like Idealist or Monster Jobs may attract too many candidates who lack the qualifications that you need. Instead, look for boards that are aimed at skilled workers in the tech sector. You have a better chance to find what you're looking for on sites like and Data Elixir.

If you’re using job boards, you should also be prepared to spend plenty of time looking at resumes, checking references, and conducting interviews. When you place an ad on a job board, you’ll probably generate a massive response — and that means that you’ll need to spend a lot of time sifting through applications and examining candidates to find that one that’s right for you.


Some companies hunt out the best tech talent by holding competitions. Sometimes referred to as hackathons, these competitions are becoming popular with larger employers, especially institutions like universities and government agencies.

Prospective employers hold hackathons that challenge competitors to solve existing problems or propose new approaches to a project. The creator of the best solution may be offered a job. One unexpected benefit of hackathons is that people who participate in such competitions may be more likely to sign up with the company. That’s good news if your company is struggling to attract and retain the best tech talent.

Of course, organizing a hackathon does come with some built-in downsides. Like most hiring processes, it involves a major time investment. You’ll have to dedicate a lot of labor hours to planning, publicizing, and judging the competition.


Sometimes, companies do well when they outsource projects to a business that specializes in machine learning and artificial intelligence. At its best, this relieves pressure on your business by shifting the project to a different team. Outsourcing can save businesses money since they won’t be paying benefits and other bonuses. Of course, you may also end up paying higher rates to outsource a project depending on the business that you contract with.

Outsourcing tends to work best when you have a well-defined project with clear benchmarks. It also helps if you have staff with the capacity to oversee the work and determine whether the progress is up to expectations.

Outsourcing may not work as well if you want to build a long-term machine learning strategy for your business which would require the ongoing involvement of a trained machine learning engineer. Likewise, outsourcing may not be right for you if you want to be more involved in the day-to-day operations of your machine learning team.
