Data Engineering Jobs vs Data Science Jobs
What is Data Engineering?
Data engineering is a subset of data science, a comprehensive term that incorporates numerous fields of information related to working with data. Fundamentally, data science is tied in with getting data for analysis to deliver significant and valuable insights. The data can be additionally applied to offer some value for machine learning, BI, data stream analysis, or any other type of analytics.
If you are a data scientist who wants to do ML modeling, taking a data engineer job might be boring for you. You sit there and write SQL all day long and think about containers, migrations, processes, and file types. A data engineer who is dedicated to only ML is called a machine learning engineer and he has a few more skills than a data engineer like putting an ML model into production.
Today it is really hard to find true data scientist jobs. Most real data scientist jobs have moved on to deep learning. Traditional ML-like Random Forest or basic algorithm-based Python modeling has moved to the cloud. That is, there are too many off-the-shelf cookie-cutter applications that just allow you to upload your data and run a few pre-built algorithms without requiring any other knowledge. Essentially, that’s what data scientists of that kind do.
Deep learning, also known as the deep neural network, is one of the approaches to machine learning. Other major approaches include decision tree learning, inductive logic programming, clustering, reinforcement learning, and Bayesian networks.
Deep Learning is a machine learning strategy that shows devices and computers how to do logical functioning. Deep learning gets its name from the way that it includes diving deep into numerous layers of the network, which additionally incorporates a hidden layer. The deeper you jump, the more intricate insights you remove. Read Deep Learning vs Machine Learning vs Artificial Intelligence.
Deep learning involves mathematical modeling, which can be thought of as a composition of simple blocks of a certain type, and where some of these blocks can be adjusted to better predict the final outcome.
Deep Learning Jobs
At present, any result that can be achieved using Random Forest, Gradient Boosting, or any other top algorithm can be replicated more or less using deep learning. Today, any real-world complex problem can only be solved using deep learning.
If you look at any complex problem that big-tier companies like Google have solved, there will be some deep learning in there somewhere. The one thing that is not clear is the title for data scientists who do deep learning exclusively instead of traditional machine learning. Deep learning scientist, or maybe deep learning engineer.

More Data Engineering Jobs
Data engineers are in increasingly high demand compared to other data-driven professions. In a sense, this represents an evolution for the broader field.
When machine learning become hot 5-8 years ago, companies decided they need people that can make classifiers on data. But then frameworks like Tensorflow and PyTorch became really good, democratizing the ability to get started with deep learning and machine learning.
This commoditized the data modeling skillset.
Today, the bottleneck in helping companies get machine learning and modeling insights into production centers on data problems.
How do you annotate data? How do you process and clean data? How do you move it from A to B? How do you do this every day as quickly as possible?
Data Science Job Market will be Competitive
It is getting harder and harder to find work that does real ML and DL. 70 – 90% of the jobs are for data engineers but are titled Data Scientists.
Due to less demand for real ML and DL, the competition is really high for those jobs. I would actually make a bold claim that Machine Learning as we knew it circa 2010 is pretty much dead! It has been democratized, automated, packaged, and put into drop-down menus so even a marketing guy can run it.
Right now the push seems to be to get the data right and the only person that can do that is the data engineer! No one is worried about the ML portion because you could just connect your BI to cloud AI and even a high-level tech-savvy manager or marketing guy can run the show! lol. Or a data engineer for that matter!
Challenges with Data Scientist Jobs
So, if you are looking for data scientist jobs, competition is going to be tougher. There are going to be fewer positions available for what is looking to be an abundance of newcomers to the market trained to do data science.
There will always be a need for people that can effectively analyze and extract actionable insights from data. But they have to be good.
Downloading a pre-trained model off the Tensorflow website on the Iris dataset probably is no longer enough to get that data science job.
It’s clear, however, with the large number of ML engineer openings that companies often want a hybrid data practitioner: someone that can build and deploy models. Or, said more succinctly, someone who can use Tensorflow but can also build it from the source.
Machine learning research tends to get its fair share of hype because that’s where all the cutting-edge stuff happens, all the AlphaGo and GPT-3 and what-not.
However, you will probably find more of those kinds of roles at industry research labs that can afford to take capital-intensive bets for long stretches of time rather than at a seed-stage startup trying to demonstrate product-market fit to investors as it raises a Series A.
Deep Learning Jobs are Increasing
Deep Learning is an extremely exciting development that has sparked an AI revolution in many aspects of our lives and is the key technology behind the recent spectacular developments in fields such as biomedical signal analysis, image recognition, driverless cars, speech processing, and natural language processing.
Deep Learning and Natural Language Processing are the Hottest In-Demand Skills
Regardless of whether it is parking assistance through technology or face recognition at the air terminal, deep learning is fuelling a ton of automation in this day and age. Notwithstanding, deep learning’s importance can be connected most to the fact that our reality is creating dramatic amounts of data today, which needs structuring on a huge scale.
Natural language processing is another skill set with the AI discipline that is more in demand this year. A lot of startups and companies are looking for people with experience in speech recognition and NLP and hires a lot of new graduates as well.
