Who is a Machine Learning Engineer?

Machine learning engineering is the process of employing software engineering concepts, analytical and data science skills, and combining both of those to take an ML model that has been generated and make it available for usage by the product or the users. Machine learning (ML) is a topic of study focused on comprehending and developing “learning” methods, or methods that use data to enhance performance on a certain set of tasks. It is regarded as a component of artificial intelligence. To generate predictions or choices without being explicitly taught to do so, machine learning algorithms develop a model based on sample data, often known as training data.

Machine learning algorithms are utilized in a wide range of applications, including computer vision, email filtering, speech recognition, and medicine, where it is difficult or impractical to create traditional algorithms to carry out the required tasks. Not all machine learning is statistical learning, although a portion of it is strongly related to computational statistics, which is centred on computer prediction. The discipline of machine learning benefits from the methodology, theory, and application domains that mathematical optimization research provides. A similar area of study is data mining, which focuses on unsupervised learning for exploratory data analysis. Some machine learning applications use data and neural networks to simulate the operation of a biological brain. Machine learning is also referred to as predictive analytics when used to solve a variety of business problems. To help create high-performance machine learning models, machine learning engineers must evaluate, organize, and analyze data as well as run tests and optimize the learning process.

A machine learning engineer is more of a tech expert that creates, updates and maintains AI systems that support models. They take algorithms developed by data scientists and scale them to work in a production environment or organizational process, in other words. MLEs make sure the models are delivered to your phones, PCs, and other electronic devices. Highly trained programmers known as machine learning engineers create artificial intelligence (AI) systems that leverage massive data sets for research, development, and generation of learning and prediction-making algorithms. To automate predictive models, machine learning engineers conduct research, create, and design self-running software.

A machine learning (ML) engineer creates artificial intelligence (AI) systems that use massive data sets to produce and construct algorithms capable of learning and eventually generating predictions. You must learn how to program if you want to work in the field of artificial intelligence and machine learning. A programmer needs to be familiar with a variety of languages, including C++, Java, and Python. However, not all successful machine learning engineers need to be experts in HTML or JavaScript. Machine learning is by nature an iterative process. To be effective in this role, one needs to enjoy that style of development. Building a machine learning system requires one to build a very simple model quickly at first, then iterates on getting it better with each iteration. Languages like R, Lisp, and Prolog have also become important languages for machine learning.

The majority of machine learning engineers have backgrounds in computer science, engineering, mathematics, or data science, however, they can come from any subject. While having a strong foundation in math and computer science is essential, many people are choosing to pursue certification courses, many of which can be completed online, to gain the additional skills and knowledge required to become a Machine Learning Engineer. These knowledge areas include understanding supervised and unsupervised learning, deep learning, regression, classification, clustering methods, and neural networks. An ML Engineer would most likely be a member of a bigger data science team, depending on the size of a business. The members of that team could be data scientists, analysts, engineers, architects, and database administrators.

Depending on their degree of authority, Machine Learning Engineers could potentially engage with a wide range of diverse stakeholders within an organization, including everyone from top business leaders to marketing, sales, IT, software development, or web development teams. The study of machine learning is still somewhat young. Numerous approaches, instruments, algorithms, and applications still need to be developed. ML engineers must prioritize learning by nature, much like software developers do. It’s also crucial to use courses, blogs, tutorials, and podcasts to stay current in a sector that is still developing and changing quickly. You should exhibit strong data science expertise and relevant experience in a similar ML function to succeed as a machine learning engineer. Someone with first-class machine learning engineering skills will be able to improve the performance of predictive automation software.

Essential Skills

  • Communication Skills: Communication skills are crucial for machine learning engineers because they frequently collaborate with other team members. They frequently communicate with the other team members to exchange ideas, go through tasks, and respond to inquiries. Additionally, they speak with clients to discuss their work and respond to inquiries regarding their projects. Your professional trajectory may change drastically if you have strong communication abilities. This is because, even though you are the best at comprehending the data and insights produced by machine learning, it is also crucial that you can communicate these insights to non-technical team members, shareholders, or clients. This may also entail employing data storytelling, in which case you must be able to present your data narratively with a beginning and an end at specific outcomes you have discovered by applying machine learning to the data. This is so that a firm may focus more on the actionable insights that can be drawn from the data, which are ultimately more essential to a company than the data analysis. And if you can successfully communicate these thoughts, the sky is the limit for you in your line of work.
  • Data Modeling and Evaluation Skills: Data modelling and evaluation skills are essential for machine learning engineers. Finding patterns that are hidden from the naked eye requires first understanding the underlying structure of the data. The data must also be evaluated using an algorithm that is appropriate for the data. For instance, the data will determine which machine learning algorithms, such as regression, classification, clustering, dimension reduction, etc., to apply. A regression approach for accuracy might be a random forest, whereas a classification algorithm for vast data and speed might be naive eyes. Similar to how the probability clustering procedure is k means and the k mode for categorical variables. To properly contribute to data modelling and evaluation, you need to be aware of all these specifics of different techniques.


  • Mathematics and Statistics knowledge: Without at least a basic understanding of math, machine learning is impossible to grasp. Whether you have formal training in math and statistics or not, you’ll need to have math skills equivalent to those found in high school to keep up. A formal concept of probability and methods developed from it are at the core of many machine learning algorithms. The study of statistics, which offers many measures, distributions, and analysis techniques required for creating and testing models from observable data, is closely related to this. Many machine learning methods are just extensions of statistical modelling techniques. Your ability to evaluate data and use it in practical applications will be aided by your statistical skills. This can assist you in creating powerful machine learning models and deciphering your research’s findings. To increase your knowledge, think about reading books or taking a statistics course.
  • Computer Science Fundamentals and Programming Skills: This is another prerequisite for developing into a competent machine learning engineer. Different computer science concepts, such as data structures (stack, queue, tree, and graph), algorithms (searching, sorting, dynamic and greedy programming), space and time complexity, etc., must be familiar to you. The good news is that if you have a bachelor’s degree in computer science, you presumably already know all of this! You should be knowledgeable in a variety of programming languages, including Python and R for machine learning and statistics, Spark and Hadoop for distributed computing, SQL for managing databases, Apache Kafka for pre-processing data, etc. It’s great if you are familiar with Python’s libraries, such as NumPy, Pandas, Matplotlib, Scikit-learn, TensorFlow, etc. Python is a very popular programming language, especially for Machine Learning and Data Science.


  • Machine Learning Algorithms Knowledge: Knowing every common machine learning algorithm is crucial for knowing when to use which algorithms. Most machine learning (ML) algorithms fall into one of three categories: supervised, unsupervised, or reinforcement learning algorithms. For example, Naive Bayes Classifier, K Means Clustering, Support Vector Machine, Apriori Algorithm, Linear Regression, Logistic Regression, Decision Trees, Random Forests, etc. are some of the more popular ones. Therefore, it’s beneficial if you have a thorough understanding of each of these algorithms before starting your career as an ML developer.
  • Neural Networks Understanding: The role of neural networks in machine learning cannot be taken for granted. These networks, which are modelled after neurons in the human brain, have multiple layers, including an input layer that receives data from the outside world and multiple hidden layers that transform it into information useful for the output layer. These networks show a keen understanding of parallel and sequential computations that are used to analyze or learn from data. There are numerous varieties of neural networks, including Feedforward Neural Networks, Radial Basis Function Neural Networks, Recurrent Neural Networks, Convolutional Neural Networks, and Modular Neural Networks. Being an ML engineer does not require you to fully comprehend all of these neural networks, but you must be familiar with the foundations.
