Here’s why so many data scientists are leaving their jobs

Yes, I am a data scientist and yes, you did read the title correctly, but someone had to say it. We read so many stories about data science being the sexiest job of the 21st century and the attractive sums of money that you can make as a data scientist that it can seem like the absolute dream job. Factor in that the field contains an abundance of highly skilled people geeking out to solve complex problems (yes it’s a positive thing to “geek out”), there is everything to love about the job.

But the truth is that data scientists typically “spend 1–2 hours a week looking for a new job” as stated in this article by the Financial Times. Furthermore, the article also states that “Machine learning specialists topped its list of developers who said they were looking for a new job, at 14.3 per cent. Data scientists were a close second, at 13.2 per cent.” These data were collected by Stack Overflow in their survey based on 64,000 developers.

I too have been in that position and have recently switched data science jobs myself.

So why are so many data scientists looking for new jobs?

Before I answer that question I should clarify that I am still a data scientist. On the whole, I love the job and I don’t want to discourage others from aspiring to be data scientists because it can be fun, stimulating and rewarding. The aim of this article is to play devil’s advocate and expose some of the negative aspects of the job.

From my perspective, here are 4 big reasons why I think many data scientists are dissatisfied with their jobs.

1. Expectation does not match reality

Big data is like teenage sex: everyone talks about it, nobody really knows how to do it, everyone thinks everyone else is doing it, so everyone claims they are doing it… — Dan Ariely

This quote is so apt. Many junior data scientists I know (this includes myself) wanted to get into data science because it was all about solving complex problems with cool new machine learning algorithms that make huge impact on a business. This was a chance to feel like the work we were doing was more important than anything we’ve done before. However, this is often not the case.

In my opinion, the fact that expectation does not match reality is the ultimate reason why many data scientists leave. There are many reasons for this and I can’t possibly come up with an exhaustive list but this post is essentially a list of some of the reasons that I encountered.

Every company is different so I can’t speak for them all but many companies hire data scientists without a suitable infrastructure in place to start getting value out of AI. This contributes to the cold start problem in AI. Couple this with the fact that these companies fail to hire senior/experienced data practitioners before hiring juniors, you’ve now got a recipe for a disillusioned and unhappy relationship for both parties. The data scientist likely came in to write smart machine learning algorithms to drive insight but can’t do this because their first job is to sort out the data infrastructure and/or create analytic reports. In contrast, the company only wanted a chart that they could present in their board meeting each day. The company then get frustrated because they don’t see value being driven quickly enough and all of this leads to the data scientist being unhappy in their role.

Robert Chang gave a very insightful quote in his blog post giving advice to junior data scientists:

It’s important to evaluate how well our aspirations align with the critical path of the environment we are in. Find projects, teams, and companies whose critical path best aligned with yours.

This highlights the 2-way relationship between the employer and the data scientist. If the company isn’t in the right place or has goals aligned with that of the data scientist then it’ll only be a matter of time before the data scientist will find something else.

For those that are interested Samson Hu has a fantastic series on how the analytics team was built at Wish which I also found very insightful.

Another reason that data scientists are disillusioned is a similar reason to why I was disillusioned with academia: I believed that I would be able to make a huge impact on people everywhere, not just within the company. In reality, if the company’s core business is not machine learning (my previous employer is a media publishing company), it’s likely that the data science that you do is only going to provide small incremental gains. These can add up to something very significant or you may be lucky to stumble on a gold mine project but this is less common.

2. Politics reigns supreme

The issue of politics already has a brilliant article dedicated to it: The most difficult thing in data science: politicsand I urge you to read it. The first few sentences from that article pretty much sum up what I want to say:

When I was waking up at 6 AM to study Support Vector Machines I thought: “This is really tough! But, hey, at least I will become very valuable for my future employer!”. If I could get the DeLorean, I would go back in time and call “Bulls**t!” on myself.

If you seriously think that knowing lots of machine learning algorithms will make you the most valuable data scientist then go back to my first point above: expectation does not match reality.

The truth is the people in the business with the most clout need to have a good perception of you. That may mean that you have to constantly do ad hoc work such as getting numbers from a database to give to the right people at the right time, doing simple projects just so that the right people have the right perception of you. I had to do this a lot in my previous place. As frustrating as it can feel, it was a necessary part of the job.
