DevSecOps Technical Evangelist

The DevSecOps Technical Evangelist exists because the hardest problem in application security isn't finding vulnerabilities — it's getting developers to care about fixing them before they ship. This role is the answer to that problem. Whether working for a security vendor or inside a large engineering organization, the evangelist's job is to meet developers where they work and make security something they do instinctively rather than something security teams enforce on them afterward.

A typical week looks nothing like a typical engineer's week. Monday might involve writing a technical post on secrets detection in GitHub Actions, including a working repository people can fork. Tuesday is a customer-facing workshop on container image scanning in a Kubernetes CI pipeline, live-coded in front of 40 engineers. Wednesday involves an internal meeting with the product team to explain why a particular policy feature is being misunderstood by developers in the field — with specific examples pulled from community forum threads. Thursday is travel to a regional conference for a 45-minute talk on software supply chain security. Friday is responding to three GitHub issues on the demo repo that people found by following the blog post.

The role requires genuine engineering ability. Audiences at KubeCon or AppSec EU are not impressed by abstract advice — they want to see a working pipeline with Trivy scanning images, OPA enforcing admission policies, and Semgrep running in the PR gate. If the demo breaks live, the evangelist needs to debug it in real time. That technical accountability is what separates effective evangelists from marketing content dressed in engineering language.

On the internal side, the role often includes building and running security champion programs: identifying engineers with security interest in each product team, giving them training and tools, and creating a feedback channel between those champions and the central security function. Done well, this multiplies the security team's reach dramatically without expanding headcount.

The visibility the role creates is real and cumulative. A well-delivered KubeCon talk reaches thousands of engineers in recorded form. A GitHub repository that solves a real pipeline problem gets starred by people at companies the speaker has never heard of. Over two or three years, a good evangelist builds name recognition in the developer security community that translates directly into career options.

Engineering foundation:

• 5+ years in application security, platform security, or DevOps/DevSecOps engineering
• Hands-on experience integrating SAST (Semgrep, Checkmarx, SonarQube), SCA (Snyk, OWASP Dependency-Check), DAST (Burp Suite, OWASP ZAP), and secrets scanning (Trufflehog, GitLeaks) into CI/CD pipelines
• Proficiency in at least one scripting language (Python preferred; Go or Bash acceptable) and one IaC tool (Terraform, Pulumi, or CDK)
• Container security: image scanning, Dockerfile hardening, Kubernetes RBAC, admission controllers, runtime policy (Falco, Sysdig)

Cloud and platform knowledge:

• Production experience in AWS, GCP, or Azure security controls: IAM least privilege, VPC architecture, KMS, secrets management (Vault, AWS Secrets Manager)
• Familiarity with GitHub Actions, GitLab CI, Jenkins, or Tekton pipeline construction
• Working knowledge of OPA/Rego or Kyverno for policy-as-code

Certifications (valued):

• AWS Security Specialty or equivalent Azure/GCP security certification
• Certified Kubernetes Security Specialist (CKS)
• CSSLP from (ISC)² for enterprise and compliance-focused audiences
• OSCP for roles emphasizing offensive tooling integration

Communication and community:

• Demonstrated public presence: conference talks, published technical writing, open-source contributions, or podcast appearances — this is not optional for competitive candidates
• Ability to explain threat models, attack chains, and mitigations without condescension to audiences ranging from junior developers to CISOs
• Experience facilitating workshops or leading training sessions for technical audiences

What separates top candidates:

• A GitHub profile with substantive security tooling or pipeline examples, not just forks
• A specific talk, post, or project that reached an audience outside their employer — and the ability to describe what worked and what didn't

The DevSecOps evangelist role sits at the intersection of two trends that are both accelerating. First, developer security tooling has exploded into a crowded market: SAST, SCA, CNAPP, DAST, ASPM — every category has five to fifteen funded vendors competing for pipeline real estate, and all of them need credible technical voices explaining why their approach matters. Second, large enterprises have realized that centralized security teams cannot scale to cover every pull request across hundreds of product teams, and internal evangelism and champion programs are the structural answer.

Vendor demand is strong and likely to stay that way. Security ISVs — Snyk, Wiz, Lacework, Semgrep, Chainguard, and a long list of Series B and C companies — compete for the same small pool of engineers who can code fluently and present publicly. The supply of genuinely credible technical evangelists is constrained by the dual requirement: most engineers who can build the demos don't want to travel and present, and most communicators who enjoy the conference circuit can't debug a Kubernetes admission webhook live on stage. That gap keeps compensation high.

The AI coding assistant wave is creating an entirely new surface area. Every organization that has deployed GitHub Copilot or similar tooling is now asking how they prevent AI-generated code from introducing vulnerabilities at scale. Evangelists who have built a specific point of view on AI security guardrails — and can demonstrate working implementations — are fielding more inbound interest than they can respond to.

The risk to the role is consolidation. If the DevSecOps tooling market contracts to three or four dominant platforms, the number of vendors needing evangelists shrinks. But even in a consolidated market, platform engineering teams at large companies will continue to need internal advocates who can drive adoption of whatever security tooling the platform exposes.

For people already in application security or DevOps engineering, the path into this role runs through building a public presence before applying — one or two accepted conference talks and a maintained GitHub repository are more persuasive than any resume line. The salary trajectory is attractive, and the career optionality created by external visibility is real: former evangelists are disproportionately represented among security startup founders, VCs, and CISOs at growth-stage companies.

Dear Hiring Manager,

I'm applying for the DevSecOps Technical Evangelist role at [Company]. I've spent six years in application security engineering, the last three building and running the developer security program at [Company] — a 1,200-engineer organization running 400+ microservices on Kubernetes across two cloud providers.

The work that's most relevant to this role was standing up our security champion program. I started with eight engineers who had expressed interest in security, gave them a curriculum I built around Semgrep custom rules and GitHub Actions pipeline integration, and created a biweekly forum where they could bring real vulnerabilities they'd found or security friction they'd encountered. Eighteen months later we had 34 active champions across 19 teams, a 60% reduction in SAST findings reaching production, and an internal Slack community with over 400 members. I presented the program design at AppSec EU last year — the talk is publicly available and has been referenced in three subsequent conference submissions by other practitioners.

On the tooling side, I maintain a public repository of pipeline security templates covering Trivy image scanning, Trufflehog pre-commit hooks, and OPA admission policies for our Kubernetes clusters. It has around 900 stars and a handful of external contributors. I use it as the basis for workshop content when I run external sessions.

I'm specifically interested in [Company]'s focus on software supply chain security — it's where I've been spending most of my independent research time over the past year, particularly around SLSA framework adoption and SBOM generation in Gradle and Maven builds. I'd welcome the chance to talk through how that work aligns with what your team is building.

[Your Name]
