POST verdict

A modern blue-team seat that earns its keep. Take it if you're equally comfortable in security and platform engineering, skip it if you're not.

Pick this if
  • You've worked closely with platform or DevOps teams already
  • You enjoy building paved roads and golden images more than gates
  • You can write production code, not just security policy
  • You're patient with embedded influence rather than top-down authority
Skip this if
  • You see security as a gate, the role won't work
  • You haven't shipped meaningful infrastructure or code
  • You want public credit for the wins

What "doing well" looks like in the seat

  • Engineering teams adopt your guardrails without being told
  • Your patterns reduce misconfigurations before they ship
  • You can defend your tooling choices to platform engineering peers
  • Your detections cover platform primitives, not just endpoints
The bit you're probably underestimating

The role only really exists at orgs with a mature platform team and a security function that's prepared to embed inside it. At less mature orgs, the title is aspirational and the day-to-day is closer to traditional cloud security with a friendlier hat. Diligence the platform team's maturity, the funding model, and who owns the paved roads. If those are unclear, the seat isn't ready.
