Quick answers
Which pays more, data engineer or security engineer?
Posted mid-bands from each occupation's own corpus: Data Engineer $80k–$133k, Security Engineer $61k–$145k. At the midpoint that favors the data engineer by about $4k a year. Only postings that state pay are counted.
Are data engineer and security engineer the same job?
No — despite the similar names, their postings demand mostly different skills. Skills both sets of postings ask for: Python, AWS, Azure, CI/CD, GCP.
Can a data engineer become a security engineer?
Skill readiness is 37 percent: that share of what security engineer postings demand, a typical data engineer profile already covers.
Can a security engineer become a data engineer?
Skill readiness is 21 percent in this direction. Estimated transition: 12–24 mo. The asymmetry is the finding: data engineer to security engineer is the easier direction (37% vs 21%).
Method: each occupation’s salary band is the posted 25th–75th percentile from its own corpus; readiness is coverage of the destination’s posting-skill weight; shared skills are read from the overlap waterfall. Pairs sharing too few skills are not scored in that direction. Refreshed with the nightly scrape.
