Math High-Pay Career in Data Science

https://towardsdatascience.com/data-science-jobs-with-their-salaries-171acd3bf9be

Gone are the days where Math graduates were destined to low-pay teachers in the 1960s to 1990s.

Now Math career is the hottest high pay job in the 2 key engines of the “4th Industrial Revolution” , ie Mind Automation by Machine Learning (in Big Data) and its ‘Young Mother’ Artificial Intelligence.

The 3 top jobs (by order of pay) :

1. Data Scientist (US $120K) :

Skills : Math (Stats, Linear Algebra, Calculus, Probability, & potentially Algebraic Topology / Homological Algebra) + A. I.

Mathematician PhD preferred.

2. Data Architect / Engineer (US $100K)

Skill: Math + IT (especially in Big Data technologies).

3. Data Analyst / (US $65K)

Skills : IT + Business + some Math (Stats).
