I see job offers asking for a “jack of all trades” in Data Science. Someone who knows everything: Data Engineer, Analyst, Scientist, and even Machine Learning Engineer.
Really? 🤦♂️ (It’s not just multipurpose positions in marketing anymore.)
Data science is a field with specialized roles, each with its own skills and tools:
📊 Data Engineer: Cleans, transforms, and moves large volumes of data. Think rivers and seas of information. Needs Spark, Hadoop, SQL, Clouds…
📈 Data Analyst: Translates that data into business language, creates visualizations, tells the story behind the numbers. Needs Python, SQL, Tableau, Power BI, and communication skills!
🔬 Data Scientist: Explore data, create predictive models, look for hidden patterns. You need Python, scikit-learn, TensorFlow, statistics…
🤖 Machine Learning Engineer: Build, optimize, and implement those models in systems and applications. You need Python, JS, APIs, Cloud…
Asking one person to do all that for a basic salary is to understand NOTHING about what is needed (the only thing missing is for them to ask you to pay for their cloud server).
It’s like asking a single doctor to be a surgeon, cardiologist, pediatrician, and radiologist all at the same time.
If you are an entrepreneur, be clear about what you need and hire the right specialist (or team).
If you’re a professional, don’t sell yourself as a “jack of all trades” if you’re not (and if you are, charge accordingly!).
Let’s stop burning professions to save a few bucks.
