Ratios of data engineers to data scientists


A common issue is to figure out the ratio of data engineers to datascientists. The general things to consider when choosing a ratio is howcomplex the data pipeline is, how mature the data pipeline is, and the levelof experience on the data engineering team.Having more data scientists than data engineers is generally an issue. Ittypically means that an organization is having their data scientists do dataengineering. As I’ve shown, this leads to all sorts of problems.A common starting point is 2-3 data engineers for every data scientist. Forsome organizations with more complex data engineering requirements, this canbe 4-5 data engineers per data scientist. This includes organizations wheredata engineering and data science are in different reporting structures. Youneed more data engineers because more time and effort is needed to create datapipelines than to create the ML/AI portion.I talk more about how data engineering and data science teams should interactwith each other in my book Data Engineering Teams.

Data Engineers doing data science


A far less common case is when a data engineer starts doing data science.There is an upward push as data engineers start to improve their math andstatistics skills. This upward push is becoming more common as data sciencebecomes more standardized. It’s leading to a brand new type of engineer.

Machine learning engineers and data engineers


The transition of data engineer to machine learning engineer is a slow-movingprocess. To be honest, we’re going to see similar revisions to what amachine learning engineer is to what we’ve seen with the definition of datascientists.To explain what I mean by slow moving, I will share the experience of thosewho I’ve seen make the transition from data engineer to machine learningengineer. They’ve spent years doing development work as a software engineerand then data engineer. They’ve always had an interest in statistics ormath. Other times, they just got bored with the constraints of being a dataengineer. Either way, this transition took years. I’m not seeing peoplebecome machine learning engineers after taking a beginning stats class orafter taking a beginning machine learning course.As I much as I razz the data scientists for being academics, data engineersaren’t the right people, either. An engineer loves trues and falses, theblack and white, and the ones and zeros of the the world. They don’t likeuncertainty. With machine learning, there is a level of uncertainty of themodel’s guess (engineers don’t like guessing, either). Unlike mostengineers, a machine learning engineer can straddle the certainty of dataengineering and the uncertainty of data science.

What Does a Machine Learning Engineer Do?


Machine learning engineers sit at the intersection of software engineering anddata science. They leverage big data tools and programming frameworks toensure that the raw data gathered from data pipelines are redefined as datascience models that are ready to scale as needed.Machine learning engineers feed data into models defined by data scientists.They’re also responsible for taking theoretical data science models andhelping scale them out to production-level models that can handle terabytes ofreal-time data.Machine learning engineers also build programs that control computers androbots. The algorithms developed by machine learning engineers enable amachine to identify patterns in its own programming data and teach itself tounderstand commands and even think for itself.

How Much Does a Data Scientist Make?


What data scientists make annually also depends on the type of job and whereit’s located. Remember, it is a much broader role than machine learningengineer. That said, according to Glassdoor, a data scientist role with amedian salary of $110,000 is now the hottest job in America.As the demand for data scientists and machine learning engineers grows, youcan also expect these numbers to rise.Related: Machine Learning Engineer Salary Guide

R vs. Python for data science: Usage


When it comes to usage in data science, experts are divided in their opinions.Some data scientists prefer R to Python because of its visualization librariesand interactive style. R comes with great abilities in data visualization,both static and interactive. Interactive visualization built with R packageslike Plotly, Highcharter, Dygraphs, and Ggiraph take the interaction betweenthe users and the data to a new level.But again, if you are looking for higher performance or structured code Pythonis the go-to language. It is because Python has some of the best librariessuch as SciKit-Learn, IPython, numpy, scipy, matplotlib, etc. NumPy is thefoundational library for scientific computing in Python, and it introducesobjects for multi-dimensional arrays and matrices, as well as routines thatallow developers to perform advanced mathematical and statistical functions onthose arrays with fewer codes. Matplotlib is the standard Python library forcreating 2D plots and graphs.Both Python and R have their individual merits. So, if you are a newbieworking on a data science project, then I would advise you to use both R andPython interchangeably.

What does a machine learning engineer do?


In practical terms, the job of a machine learning engineer is close to that ofa data scientist. Both roles work with vast quantities of information, requireexceptional data management skills and the ability to perform complex modelingon dynamic data sets.But here the similarity ends. Data professionals produce insights, usually inthe form of charts or reports that are presented to a human audience. Machinelearning engineers, on the other hand, design self-running software toautomate predictive models. Each time the software performs an operation, ituses those results to carry out future operations with a greater degree ofaccuracy. This is how the software, or machine, “learns.”A well-known example of ML is the recommendation algorithm of Netflix, Amazonand other consumer-facing services. Each time a user watches a video orsearches for a product, these sites add more data points to its algorithm. Asthe amount of data grows, the algorithm’s recommendations to the user forother content become more accurate — all without any kind of humanintervention.ML is closely related to AI, and ML encompasses deep learning (DL). Thissubfield uses artificial neural networks to “think” and solve complex problemswith multi-layered (deep) data sets. Some commons examples of DL includevirtual assistants, translation apps, chatbots and driverless cars. Over time,these technologies will become even more accurate and practical.

Why machine learning engineers are in demand


Businesses today are awash in data, from customer interactions to IoTnetworks. Attempting to process all that information manually is like drinkingfrom a fire hose. Machine learning has become essential for taking fulladvantage of a company’s data.Applications of ML are as varied as the data itself. A few common applicationsinclude: * Image and speech recognition — Machine learning excels at auto-tagging images, text-to-speech conversions and anything else that requires turning unstructured data into useful information. * Customer insight — Association rule learning, the way ML software makes connections, drives the algorithms at the heart of e-commerce, telling consumers who buy product A that they might like product X. * Risk management and fraud prevention — ML algorithms can analyze huge volumes of historical data to make financial predictions, from future investment performance to the risk of loan defaults. Regression testing also makes it easier to spot fraudulent transactions in real time.

What to expect in a machine learning engineer job description


Because ML is an emerging role, not many IT specialists have direct experiencewith it. That’s why most machine learning engineer job descriptions today seekout data scientists with a programming background.The reverse can also be true: Coders and programmers with solid data skillscan transition to become machine learning engineers, though they may needexperience in a data role beforehand.A job description for machine learning engineers typically includes thefollowing: * Advanced degree in computer science, math, statistics or a related discipline * Extensive data modeling and data architecture skills * Programming experience in Python, R or Java * Background in machine learning frameworks such as TensorFlow or Keras * Knowledge of Hadoop or another distributed computing systems * Experience working in an Agile environment * Advanced math skills (linear algebra, Bayesian statistics, group theory) * Strong written and verbal communications

Machine learning engineer salary


As a fairly new job title, there aren’t enough data points to give adefinitive range for machine learning engineer salaries. However, as this rolelies between data science and software engineering, your could use informationfrom the Robert Half Technology 2020 Salary Guide to make a fairly accurateestimate of how much employers are likely to offer potential new hires. Hereare some starting salary midpoints (national median salary) for relatedpositions: * Big data engineer: $163,250 * Data architect: $141,250 * Data scientist: $125,250 * Data modeler: $101,750 * Developer/programmer analyst: $108,500 * Software engineer: $125,750

2. Machine learning and data science is the most sought-after group of


software engineersAnd while the average software engineer already gets a lot of attention fromrecruiters, certain specialties and skillsets tend to draw even higheroutreach volume.Here is how the supply of software engineering talent stacks up relative todemand from companies:Engineers specializing in machine learning & data science top the overallgroup when it comes to market demand albeit their talent pool is the smallest.They are followed by those who work in mobile and front-end development, twoof the specialties with larger talent pools. And if you need to hire test andquality assurance talent, you’ll likely have an easier time relative to otherspecialties.”
