How to become a DevSecOps Engineer
A DevSecOps engineer moves security into the delivery pipeline itself: hardening containers and CI runners, scanning infrastructure as code before it deploys, and gating a release on a failed security check rather than catching the problem after the fact. Most people reach this title from a platform or DevOps background rather than a pure security one.
Typical entry route: Mid level, and more often reached from a DevOps or platform engineering background than from a security-first career path. Cloud security certifications carry more weight here than any dedicated DevSecOps credential, since none is yet standardized.
What the job asks for
Skills real devsecops engineer postings ask for
Marked against what SecMissions teaches today: covered means a mission builds this skill directly, partly means the underlying reasoning is taught but the tool or workflow context is not, and planned means it is an open gap.

Where this role is hiring
Demand, sourced
This is one of the more clearly emerging titles in the field, and the closest tracked skills gap figure is security engineering: the 2025 ISC2 Cybersecurity Workforce Study found 27 percent of teams naming security engineering as a critical or significant gap, and named risk assessment, application security, and cloud security as adjacent, overlapping shortages this role often ends up covering.
Honest gaps
What we do not cover yet
We would rather tell you this than let a gap surface after you have paid for a plan.
- A dedicated CI or CD pipeline security domain, which does not exist in the catalog today.
- Infrastructure as code scanning and GitOps workflow content.
- Kubernetes cluster hardening beyond a single container boundary mission.
