A lot of this work is called explanatory data analysis or EDA for short.<\/p>\n<p class=\"wp-block-paragraph\">The latter is mainly about building PoC machine learning models and decision systems that benefit the business. Then, working with software and machine learning engineers, to deploy those models to production and monitor their performance.<\/p>\n<p class=\"wp-block-paragraph\">Many of the machine learning algorithms will typically be on the simpler side and be regular supervised and unsupervised learning models, like:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">XGBoost<\/li>\n<li class=\"wp-block-list-item\">Linear and logistic regression<\/li>\n<li class=\"wp-block-list-item\">Random forest<\/li>\n<li class=\"wp-block-list-item\">K-means clustering<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">I was a data scientist at my old company, but I mainly built machine learning models and didn\u2019t run many A\/B tests or experiments. That was work that was carried out by data analysts and product analysts.<\/p>\n<p class=\"wp-block-paragraph\">However, at my current company, data scientists don\u2019t build machine learning models but mainly do deep-dive analysis and measure experiments. Model development is mainly done by machine learning engineers.<\/p>\n<p class=\"wp-block-paragraph\">It all really comes down to the company. Therefore, it is really important that you read the job description to make sure it\u2019s the right job for you.<\/p>\n<h3 class=\"wp-block-heading\">What do they\u00a0use?<\/h3>\n<p class=\"wp-block-paragraph\">As a data scientist, these are generally the things you need to know (it\u2019s not exhaustive and will vary by role):<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Python and SQL<\/li>\n<li class=\"wp-block-list-item\">Git and GitHub<\/li>\n<li class=\"wp-block-list-item\">Command Line (Bash and Zsh)<\/li>\n<li class=\"wp-block-list-item\">Statistics and maths knowledge<\/li>\n<li class=\"wp-block-list-item\">Basic machine learning skills<\/li>\n<li class=\"wp-block-list-item\">A bit of cloud systems (AWS, Azure, GCP)<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">I have roadmaps on becoming a data scientist that you can check out below if this role interests you.<\/p>\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-towards-data-science wp-block-embed-towards-data-science\">\n<div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"Ib2OCLqSbX\"><p><a href=\"https:\/\/towardsdatascience.com\/how-id-become-a-data-scientist-if-i-had-to-start-over-d966a9de12c2\/\">How I\u2019d Become a Data Scientist (If I Had to Start Over)<\/a><\/p><\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" title=\"\u201cHow I\u2019d Become a Data Scientist (If I Had to Start Over)\u201d \u2014 Towards Data Science\" src=\"https:\/\/towardsdatascience.com\/how-id-become-a-data-scientist-if-i-had-to-start-over-d966a9de12c2\/embed\/#?secret=cg3DS3iK4r#?secret=Ib2OCLqSbX\" data-secret=\"Ib2OCLqSbX\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div>\n<\/figure>\n<h2 class=\"wp-block-heading\">Machine Learning\u00a0Engineer<\/h2>\n<h3 class=\"wp-block-heading\">What is\u00a0it?<\/h3>\n<p class=\"wp-block-paragraph\">As the title suggests, a machine learning engineer is all about building machine learning models and deploying them into production systems.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">It originally came from software engineering, but is now its own job\/title.<\/p>\n<p class=\"wp-block-paragraph\">The significant distinction between machine learning engineers and data scientists is that machine learning engineers deploy the algorithms.<\/p>\n<p class=\"wp-block-paragraph\">As leading AI\/ML practitioner <a href=\"https:\/\/huyenchip.com\/ml-interviews-book\/contents\/1.1.3.3-machine-learning-engineer-vs.-data-scientist.html\" rel=\"noreferrer noopener\" target=\"_blank\">Chip Huyen<\/a> puts it:<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><em>The goal of data science is to <strong>generate business insights<\/strong>, whereas the goal of ML engineering is to <strong>turn data into products<\/strong>.<\/em><\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\">You will find that data scientists often come from a strong maths, statistics, or economics background, and machine learning engineers come more from science and engineering backgrounds.<\/p>\n<p class=\"wp-block-paragraph\">However, there is a big overlap in this role, and some companies may bundle the data scientist and machine learning engineer positions into a single job, frequently with the data scientist title.<\/p>\n<p class=\"wp-block-paragraph\">The machine learning engineer job is typically found in more established tech companies; however, it is slowly becoming more popular over time.<\/p>\n<p class=\"wp-block-paragraph\">There also exist further specialisms within the machine learning engineer role, like:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">ML platform engineer<\/li>\n<li class=\"wp-block-list-item\">ML hardware engineer<\/li>\n<li class=\"wp-block-list-item\">ML solutions architect<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">Don\u2019t worry about these if you are a beginner, as they are pretty niche and only relevant after a few years of experience in the field. I just wanted to add these so you know the various options out there.<\/p>\n<h3 class=\"wp-block-heading\">What do they\u00a0use?<\/h3>\n<p class=\"wp-block-paragraph\">The tech stack is quite similar for machine learning engineers as for data scientists, but has more software engineering elements:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Python and SQL, however, some companies may require other languages. For example, in my current role, Rust is needed.<\/li>\n<li class=\"wp-block-list-item\">Git and GitHub<\/li>\n<li class=\"wp-block-list-item\">Bash and Zsh<\/li>\n<li class=\"wp-block-list-item\">AWS, Azure or GCP<\/li>\n<li class=\"wp-block-list-item\">Software engineering fundamentals like CI\/CD, MLOps and Docker.<\/li>\n<li class=\"wp-block-list-item\">Excellent machine learning knowledge, ideally a specialism in an area.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\">AI Engineer<\/h2>\n<h3 class=\"wp-block-heading\">What is\u00a0it?<\/h3>\n<p class=\"wp-block-paragraph\">This is a new title that cropped up with all the AI hype going on now, and to be honest, I think it\u2019s an odd title and not really needed. Often, a machine learning engineer will do the role of an AI engineer at most companies.<\/p>\n<p class=\"wp-block-paragraph\">Most AI engineer roles are actually about GenAI, not AI as a whole. This distinction normally makes no sense to people outside of the industry.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">However, AI encompasses almost any decision-making algorithm and is larger than the machine learning field.<\/p>\n<figure class=\"wp-block-image\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/contributor.insightmediagroup.io\/wp-content\/uploads\/2025\/05\/0JOKOqqfegxrJAwhC.png?ssl=1\" alt=\"\" class=\"wp-image-604458\"><figcaption class=\"wp-element-caption\">Image by\u00a0author.<\/figcaption><\/figure>\n<p class=\"wp-block-paragraph\">The current definition of an AI engineer is someone who works mainly with LLM and GenAI tools to help the business.<\/p>\n<p class=\"wp-block-paragraph\">They don\u2019t necessarily develop the underlying algorithms from scratch, mainly because it\u2019s hard to do unless you\u2019re in a research lab, and many of the top models are open-sourced, so you don\u2019t need to reinvent the wheel.<\/p>\n<p class=\"wp-block-paragraph\">Instead, they focus on adapting and building the product first, then worrying about the model fine-tuning afterwards. So, they wu<\/p>\n<p class=\"wp-block-paragraph\">It is a lot closer to traditional software engineering than the machine learning engineer role as it currently stands. Although many machine learning engineers will operate as AI engineers, the job is new and not fully fleshed out yet.<\/p>\n<h3 class=\"wp-block-heading\">What do they\u00a0use?<\/h3>\n<p class=\"wp-block-paragraph\">This role is evolving quite a bit, but in general, you need good knowledge of all the latest GenAI and LLM trends:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Solid software engineering skills<\/li>\n<li class=\"wp-block-list-item\">Python, SQL and backend langauges like Java or GO are useful<\/li>\n<li class=\"wp-block-list-item\">CI\/CD<\/li>\n<li class=\"wp-block-list-item\">Git<\/li>\n<li class=\"wp-block-list-item\">LLMs and transformers<\/li>\n<li class=\"wp-block-list-item\">RAG<\/li>\n<li class=\"wp-block-list-item\">Prompt engineering<\/li>\n<li class=\"wp-block-list-item\">Foundational models<\/li>\n<li class=\"wp-block-list-item\">Fine tuning<\/li>\n<\/ul>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">I also recommend you check out Datacamp\u2019s associates AI engineer for data scientist track, that will also set you up nicely for a career as a data scientist. This is linked in the description below.<\/p>\n<\/blockquote>\n<h2 class=\"wp-block-heading\">Research Scientist\/Engineer<\/h2>\n<h3 class=\"wp-block-heading\">What is\u00a0it?<\/h3>\n<p class=\"wp-block-paragraph\">The previous roles were mainly industry positions, but these next two will be research-based.<\/p>\n<p class=\"wp-block-paragraph\">Industry roles are mainly associated with business and are all about generating business value. Whether you use linear regression or a transformer model, what matters is the impact, not necessarily the method.<\/p>\n<p class=\"wp-block-paragraph\">Research aims to expand the current knowledge capabilities theoretically and practically. This approach revolves around the scientific method and deep experiments in a niche field.<\/p>\n<p class=\"wp-block-paragraph\">The difference between what\u2019s research and industry is vague and often overlaps. For example, a lot of the top research labs are actually big tech companies:<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Meta Research<\/li>\n<li class=\"wp-block-list-item\">Google AI<\/li>\n<li class=\"wp-block-list-item\">Microsoft AI<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">These companies initially started to solve business problems, but now have dedicated research sectors, so you may work on industry and research problems. Where one begins and the other ends is not always clear.<\/p>\n<p class=\"wp-block-paragraph\">If you are interested in exploring the differences between research and industry more deeply, I recommend you read this document. It\u2019s the first lecture of <a href=\"https:\/\/docs.google.com\/document\/d\/1VuofeF5okBATz1F7HRQmOgi5Jc4bmUiHMYjRqwF-29s\/edit?usp=sharing\" rel=\"noreferrer noopener\" target=\"_blank\">Stanford\u2019s CS 329S, lecture 1: Understanding machine learning production<\/a>.<\/p>\n<p class=\"wp-block-paragraph\">In general, there are more industry positions than research, as only the large companies can afford the data and computing costs.<\/p>\n<p class=\"wp-block-paragraph\">Anyway, as a research engineer or scientist, you will essentially be working on cutting-edge research, pushing the boundaries of machine learning knowledge.<\/p>\n<p class=\"wp-block-paragraph\">There is a slight distinction between the two the jobs. As a research scientist, you will need a Phd, but this is not necessarily true for a research engineer.<\/p>\n<p class=\"wp-block-paragraph\">A research engineer typically implements the theoretical details and ideas of the research scientist. This role is usually at large, established research companies; in most situations, the research engineer and scientist jobs are the same though.<\/p>\n<p class=\"wp-block-paragraph\">Companies may offer the research scientist title as it gives you more \u201cclout\u201d and makes you more likely to take the job.<\/p>\n<h3 class=\"wp-block-heading\">What do they\u00a0use?<\/h3>\n<p class=\"wp-block-paragraph\">This one is similar to machine learning engineering, but the depth of knowledge and qualifications is often greater.<\/p>\n<ul class=\"wp-block-list\">\n<li class=\"wp-block-list-item\">Python and SQL<\/li>\n<li class=\"wp-block-list-item\">Git and GitHub<\/li>\n<li class=\"wp-block-list-item\">Bash and Zsh<\/li>\n<li class=\"wp-block-list-item\">AWS, Azure or GCP<\/li>\n<li class=\"wp-block-list-item\">Software engineering fundamentals like CI\/CD, MLOps and Docker.<\/li>\n<li class=\"wp-block-list-item\">Excellent machine learning knowledge and a specialism in a cutting-edge area like computer vision, reinforcement learning, LLM, etc.<\/li>\n<li class=\"wp-block-list-item\">PhD or at least a master\u2019s in a relevant discipline.<\/li>\n<li class=\"wp-block-list-item\">Research experience.<\/li>\n<\/ul>\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dotted\">\n<p class=\"wp-block-paragraph\">This article has just scratched the surface of machine learning roles, and there are many more niche jobs and specialisms within these four or five I mentioned.<\/p>\n<p class=\"wp-block-paragraph\">I always recommend starting your career by getting your foot in the door and then pivoting to the direction you want to go. This strategy is much more effective than tunnel vision for only one role.<\/p>\n<h2 class=\"wp-block-heading\">Another thing!<\/h2>\n<p class=\"wp-block-paragraph\">I offer 1:1 coaching calls where we can chat about whatever you need\u200a\u2014\u200awhether it\u2019s projects, <a href=\"https:\/\/towardsdatascience.com\/tag\/career-advice\/\" title=\"Career Advice\">Career Advice<\/a>, or just figuring out your next step.
