What Machine Learning Engineer Does

In the past few years, the roles of those who work in machine learning have radically evolved with the addition of artificial intelligence to the mix. Machine learning engineers are computer programmers, but they not only program machines to execute specific tasks. Rather, they create programs that allow machines to take action without special instructions or human intervention.

Role of Machine Learning Engineers

The main aim of machine learning engineers is to improve the operational efficiency of the processes. One of the hardest tasks in machine learning is to create a result-oriented model. In reality, an engineer’s role is similar to a data scientist since both require large volumes of data and expertise in processing and evaluating data sets to create the algorithm and model. The following list summarizes the possible roles and duties of an engineer.

  • Machine learning engineers must understand the performance objectives and business aims behind model development. They must be able to develop an ML model purely based on the desired
  • Machine learning engineers collect, analyze, and processes data. They validate data quality and perform data cleaning if the available data is disorganized or contains a lot of unnecessary information.
  • To create a machine learning model, an engineer should select the optimal training datasets because the model's performance heavily depends on the quality of training.
  • ML engineers present the data in a visual form and extract useful insights from it. Based on the data's insights, the engineers select a machine learning system, perform additional research, and evaluate the design
  • An engineer must select and implement an appropriate machine learning algorithm for a specific application.
  • Engineers must train the models and fine-tune model parameters. They should statistically analyze the results.
  • Develop prototypes to analyze the model in real-time to evaluate performance and identify errors and irregularities.

Finally, machine learning engineers train, optimize, validate, and deploy machine learning systems for particular applications. The data engineers prepare the data, and the ML engineers expand on the data engineer’s work. However, the most relevant element is that ML engineers can introduce more complex ML transformations, such as feature extraction, dimensional reduction, outlier identification, missing value imputation, and normalization. Suppose the data is ready to feed the ML algorithm. In that case, the ML engineer must correctly set the training algorithm and implement it in a suitable period to deliver a satisfactory result.


Machine learning engineers need a basic understanding of mathematics, statistics, probability, data science, and software engineering

  • Machine-learning engineers' prime focus and objectives are to serve as an interface between data science, statistics, and software engineering.
  • They are responsible for developing production-ready, robust ML and AI systems, applications, and facilities in collaboration with software engineers.
  • ML engineers combine their ML and AI experience with programming and software engineering skills to make it simpler to access models and analyses that are otherwise challenging to understand and technically complicated.
  • ML engineers observe the jobs that humans are currently carrying out to look for ways to automate them.
