A DevSecOps engineer is a software professional who builds security directly into the development and deployment pipeline, rather than treating it as a final checkpoint before release. The role combines traditional DevOps skills (automating builds, managing infrastructure, streamlining deployments) with hands-on security expertise like vulnerability scanning, security testing, and compliance enforcement. If a DevOps engineer asks “how do we ship faster?”, a DevSecOps engineer asks “how do we ship faster without introducing security holes?”
What “Shift Left” Actually Means
The core philosophy behind DevSecOps is called “shifting security left,” which refers to moving security work earlier in the software development life cycle. In a traditional setup, a security team reviews code after it’s already been built and packaged. Problems found at that stage are expensive and slow to fix because developers have to revisit work they finished weeks ago.
A DevSecOps engineer embeds security into every phase, from initial design through development, testing, and deployment. That means automated security checks run every time a developer pushes new code, not just before a release. Vulnerabilities get caught in minutes instead of weeks, and developers fix them while the code is still fresh in their minds.
How the Role Differs From DevOps
A standard DevOps engineer focuses on collaboration between development and operations teams, building CI/CD pipelines, managing cloud infrastructure, and automating repetitive tasks. A DevSecOps engineer does all of that but extends the pipeline to include security testing and compliance checks at each stage. The role also involves working closely with dedicated security teams and fostering a culture where developers and operations staff share responsibility for security rather than treating it as someone else’s problem.
In practical terms, a DevOps engineer might set up an automated pipeline that builds, tests, and deploys an application. A DevSecOps engineer would add vulnerability scans, dependency checks, and compliance gates to that same pipeline so insecure code can’t reach production without being flagged.
Day-to-Day Responsibilities
The specific tasks vary by company, but a DevSecOps engineer’s work generally falls into a few categories:
- Integrating security tools into CI/CD pipelines. This includes setting up static application security testing (SAST), which scans source code for flaws before it’s compiled, and dynamic application security testing (DAST), which probes a running application from the outside to find vulnerabilities an attacker could exploit. Some teams also use interactive application security testing (IAST), which combines both approaches by monitoring an app in real time during testing.
- Automating vulnerability scanning. Rather than running manual security audits, a DevSecOps engineer configures tools to automatically scan code, containers, and infrastructure configurations every time something changes. This includes checking third-party libraries and dependencies for known security issues.
- Monitoring production environments. Code changes constantly as new patches, libraries, and configurations are introduced, and each change can expose new vulnerabilities. DevSecOps engineers set up and manage security information and event management (SIEM) systems and runtime protections that detect and respond to attacks as they happen.
- Writing and enforcing security policies as code. Instead of a PDF document listing security rules, a DevSecOps engineer translates those rules into automated checks. If a policy says databases must be encrypted, the pipeline automatically blocks any deployment that creates an unencrypted database.
- Training development teams. A significant part of the role is teaching developers and operations staff to recognize security concerns and address them proactively, rather than waiting for a security review to catch problems.
Technical Skills You Need
DevSecOps sits at the intersection of three disciplines, so the skill set is broad. On the DevOps side, you need fluency with CI/CD platforms (Jenkins, GitLab CI, GitHub Actions), containerization tools (Docker, Kubernetes), infrastructure-as-code frameworks (Terraform, Ansible), and at least one major cloud provider (AWS, Azure, or Google Cloud).
On the security side, you need working knowledge of SAST and DAST tools like SonarQube, Checkmarx, OWASP ZAP, or Burp Suite. Familiarity with container security scanning, secrets management (HashiCorp Vault, for example), and compliance frameworks relevant to your industry is also expected. You should understand common vulnerability types listed in the OWASP Top 10 and know how to remediate them.
Scripting is essential. Python, Bash, and Go are the most common languages used to glue security tools into pipelines and automate workflows. You don’t necessarily need to be a full-stack developer, but you need to read and write code comfortably enough to review pull requests for security issues and build custom automation.
Salary Expectations
DevSecOps engineers command strong salaries because the role requires both infrastructure and security expertise. As of early 2025, senior DevSecOps engineers in the United States earn an average of about $133,000 per year. The range is wide depending on experience:
- Entry-level (less than 1 year): around $84,000
- Early career (1 to 2 years): around $102,000
- Mid-level (2 to 4 years): around $136,000
- Senior (5 to 8 years): around $152,000
- Expert (8+ years): around $168,000
Top earners at the 90th percentile reach roughly $150,000 even at the senior title level, and compensation at large tech companies or in high-cost metro areas can push well above these figures when stock grants and bonuses are included.
How to Break Into the Role
Most DevSecOps engineers don’t start in the role directly. The two most common paths are moving laterally from a DevOps or site reliability engineering (SRE) background and adding security skills, or coming from a cybersecurity background and learning infrastructure automation and CI/CD tooling. Either path works, but the DevOps-first route is slightly more common because pipeline automation is the foundation everything else builds on.
Certifications can help signal your skills to employers. The Certified DevSecOps Professional (CDP), AWS Certified Security Specialty, and CompTIA Security+ are frequently listed in job postings. That said, hands-on experience matters more than credentials. Building a home lab where you set up a CI/CD pipeline with integrated security scanning, or contributing to open-source security tooling, demonstrates practical ability in ways a certification alone cannot.
Start by adding security scanning to an existing pipeline at your current job, even if nobody asked you to. Running a free SAST tool against your codebase and presenting the findings to your team is the kind of initiative that both builds your skills and makes the case for a formal DevSecOps function.
Who Hires DevSecOps Engineers
Any organization that ships software and cares about security, which increasingly means every organization. Financial services, healthcare, and government contractors have the most urgent need because of strict regulatory requirements around data protection. But tech companies, e-commerce platforms, and SaaS providers hire aggressively for the role as well, especially as cloud-native architectures make security automation both more complex and more critical.
Job titles vary. You might see “DevSecOps Engineer,” “Security Automation Engineer,” “Platform Security Engineer,” or “Cloud Security Engineer” used for positions with largely overlapping responsibilities. When evaluating job postings, focus on whether the role involves embedding security into development pipelines rather than relying on the title alone.
