How does this role differ from a SOC analyst?
SOC analysts watch live telemetry and respond to alerts as they fire. Engineering-side security work happens earlier: modelling threats against a design, wiring scanners into pipelines, fixing whole classes of vulnerability in shared libraries, and setting identity and secrets standards. One reduces time to detect; the other reduces how much there is to detect.
