Security Engineer vs Site Reliability Engineer: which is more exposed to AI?
Effectively tied: 3 points separate Security Engineers from Site Reliability Engineers.
Security Engineer scores 40% time-weighted AI exposure and Site Reliability Engineer scores 43% — close enough that the headline number tells you almost nothing. The difference lives underneath it: Security Engineers lose the most ground on "generate security reports" (82%), while for Site Reliability Engineers it is "write runbooks and documentation" (85%). Both roles sit inside Computer & Math, so the exposure difference reflects task design rather than a change of field.
Seven dimensions, side by side.
What actually creates the gap.
Both roles hand a similar slice of the week to substitutable work — 19% for Security Engineers, 23% for Site Reliability Engineers — but it is different work. Security Engineer exposure concentrates in "generate security reports"; Site Reliability Engineer exposure concentrates in "write runbooks and documentation". Two roles can share a score and face completely different disruption timelines.

Both roles lean on judgement, cognitive, procedural — that is the part of your experience that travels intact. Beyond that, the two capability profiles are unusually close: no dimension separates them by more than 15 points, which is why the switch difficulty below reads the way it does.
Site Reliability Engineer appears in our dataset as a mapped adjacent career for Security Engineers: the move raises exposure by 3 points, landing at 43%. Switch difficulty reads low — capability profiles are 5 points apart on average and both sit in the same family.

Is Security Engineer or Site Reliability Engineer more at risk from AI?
Site Reliability Engineer. It scores 43% time-weighted AI exposure against 40% for Security Engineer — a 3-point gap. 23% of site reliability engineer work time is already fully substitutable by current models, versus 19% for Security Engineers.
Which pays more, Security Engineer or Site Reliability Engineer?
Site Reliability Engineer, by roughly $10k at the median ($135k versus $125k). Note that the higher-paying role here is also the more AI-exposed one, which matters if you are weighing pay against durability.
Can a security engineer switch to being a site reliability engineer?
Site Reliability Engineer appears in our dataset as a mapped adjacent career for Security Engineers: the move raises exposure by 3 points, landing at 43%. Switch difficulty reads low — capability profiles are 5 points apart on average and both sit in the same family.
Which role is growing faster, Security Engineer or Site Reliability Engineer?
Security Engineer, at 30% projected ten-year growth versus 18% — a 12-point difference. Growth and AI exposure are separate signals: a role can grow in headcount while the content of the work is substantially rewritten.
