2) What is a machine learning engineer?

A machine learning engineer is like a software engineer by profession and sits at the intersection of software engineers and data scientists but with a specialization in machine learning. The focus of ML engineers goes beyond particularly programming machines to perform specific tasks. They are responsible for the end-to-end implementation and optimization of machine learning algorithms.

The final output of an ML engineering is a working software product ( not the visualizations or analytical insights created along the way), and the “audience” for this output are other software pieces that run with minimal or no human intervention. An ML engineer is responsible for handling the theoretical data science models and scaling them up for production levels so they can take a substantial amount of real-time data. To get a better understanding on who is a machine learning engineer, let’s look at what does a machine learning engineer does on a day-to-day basis.

What does a machine learning engineer do?

A machine learning engineer develops and implements machine learning algorithms and models to solve complex problems. They collect and analyze data, design and train models, and deploy them in production systems. They work closely with data scientists and software engineers to build scalable and efficient machine learning solutions.

A machine learning engineer performs the following tasks-

  • Implement statistical analysis and machine learning into highly available and high performance production level systems to provide ease of access to users.

  • Automate feature engineering, model training, and evaluation process.

  • Enrich machine learning frameworks and libraries.

  • Develop API’s or web services for serving the model outcomes to internal teams, stakeholders, or users.

  • Train and re-train machine learning systems as and when required.

  • Translate the machine learning models defined by data scientists from environments like Python and R notebooks to analytic applications.

3) Machine Learning Engineer vs Data Scientist

You might hear the terms data scientist and machine learning engineer used interchangeably but these are two different job roles. Talking at a high level, we are trying to differentiate between scientists and engineers and it is pretty much obvious that the two are different job roles. The Machine Learning engineer role is very much close to that of a data scientist because both work with large amounts of data and require skills to perform complex data modeling. But this is where the similarities between the two job roles end and this sparks a debate on the topic of data scientist vs machine learning engineer.

There are several definitions floating around the Internet for both job roles but these two professionals work in collaboration with each other to realize a quick and effective delivery of business value. A data scientist produces meaningful insights usually in the form of reports or charts while a machine learning engineer develops self-running software to automate predictive machine learning models. An ML engineer’s job role is the subset of a data scientist’s job role. A machine learning engineer acts as a bridge between the model-building task of the data scientist and the development of production-ready robust machine learning platforms, systems, and services.

A major difference between a data scientist and an ML engineer is that a data scientist asks “What is the best machine learning algorithm to solve a given business problem?” and tries to find an answer to the question by testing various hypotheses. On the contrary, an ML engineer asks “What is the best system to solve the problem?” and finds a solution by building an automated process that can be used for speeding up the testing of hypotheses. A machine learning engineer feeds data into the machine learning models defined by data scientists. Both data scientists and machine learning engineers are vital throughout the life cycle of a big data project and work together harmoniously to complement each other.

Here’s a list of machine learning interview questions to get you started.

Yes, the beauty of a machine learning engineer is that they can handle the end-to-end development of a machine learning solution. But, every ML engineer has his own strengths, interests, and specialized skills. Chances are that the hiring manager will ask you whether you prefer working on NLP problems or love building deep learning models or have an affinity towards computer vision. Don’t be afraid to share your specialties, and show how you specialize in one skill versus the other.

Companies will ask you to whiteboard a business use case during your interview just to understand your thought process and how well you code and analyze real-world business problems. Make sure you’re prepared for solving a custom machine learning project. The hiring managers will set up a business problem they already are working on and might ask you to propose an optimal machine learning solution for the same. For example, say if you are being interviewed at Wayfair they might ask you broad questions like “How do we optimize our television advertising budget?”. The hiring manager here is expecting you to ask other relevant questions and initiate discussion on the various data sources you might need, the metrics you will need to track, and then talk about the machine learning algorithms that you can implement to solve the given problem. The best way to prepare for a whiteboard data challenge to ace the machine learning interview is to practice diverse machine learning projects and get exposure to as many datasets and machine learning concepts as possible.
