50% of companies have between 1-10 data scientists on staff. The percentage with 11 or more data scientists increased from 18% in 2018 to 39% in 2024. (Algorithmia)
-
81% of companies with extensive machine learning experience have embraced the "data scientist" job title, while 39% use "machine learning engineer." (O‘Reilly)
Average US Salary: Machine Learning Roles
| Role | 2022 Average Salary | 2021 Average Salary | Increase |
|---|---|---|---|
| Machine Learning Engineer | $146,085 | $137,845 | 6% |
| Data Scientist | $120,000 | $117,345 | 2% |
The exponential growth in machine learning job postings and salaries makes sense given limited talent supply struggling to keep pace with surging employer demand.
In my experience, organizations are being forced to grow their own in-house machine learning talent through training and development programs. The war for talent also drives many to partner with specialized machine learning consultancies like ours to supplement their teams.
