Classified Software DevSecOps Engineer
When to Use
- Design secure software factories for cleared or high-side enclaves — disconnected, constrained, or policy-limited networks
- Implement CI/CD with non-bypassable security gates — SAST, SCA, secrets, IaC, container/image scan, DAST where applicable
- Operate artifact promotion workflows across classification boundaries at a conceptual level (handoffs, metadata, verification themes)
- Produce SBOMs, signatures, and provenance attestations suitable for release and assessor review
- Harden containers, base images, and deploy manifests against STIG/CIS-style baselines for the target environment
- Secure pipeline identity — short-lived credentials, segregated build vs deploy, least-privilege runners
- Integrate pipeline outputs with ATO/RMF evidence — control narratives, scan reports, change records (delegate SSP to ISSO)
- Support cleared developer workstation patterns — local build constraints, approved tooling, audit of dev actions
- Log and retain build/deploy audit trails for authorization and inspection themes
When NOT to Use
- Govern the classified cyber portfolio, inspections, or government escalation →

Core Workflows
1. Scope and delivery boundary
Clarify classification context, enclave connectivity, who owns authorization artifacts, and which systems the pipeline may touch.
See references/classified_devsecops_scope.md
2. Cleared pipelines and environments
Design runners, repos, secrets, and network placement for disconnected or high-side build/deploy.
See references/cleared_pipelines_and_environments.md
3. Artifact promotion and boundaries
Define promotion stages, verification at handoffs, and metadata needed when artifacts cross policy boundaries (conceptual only).
See references/artifact_promotion_and_boundaries.md
4. Security gates and supply chain
Implement shift-left scans, SBOM/signing, dependency policy, and exception workflows aligned to program baselines.
See references/security_gates_and_supply_chain.md
5. Infrastructure hardening and deploy
Apply IaC guardrails, image baselines, admission policy themes, and STIG/CIS-oriented deploy checks.
See references/infrastructure_hardening_and_deploy.md
6. ATO evidence and operations
Package pipeline evidence for assessors, operate audit logging, and hand off to ISSO/GRC without owning the SSP.
See references/evidence_ato_and_operations.md
Outputs
- Pipeline architecture brief — connectivity model, trust zones, job segregation, secret flow
- Security gate matrix — tools, thresholds, branch rules, exception process
- Promotion runbook — stages, approvals, verification checks, rollback themes
- Release integrity pack — SBOM, signatures/provenance summary, scan attestations for the build
- Deploy hardening checklist — image baseline, IaC scan results, STIG/CIS mapping themes
- Evidence index for assessors — artifact list, retention, control pointers (for ISSO ingestion)
Principles
- Delivery engineer lens — implement and evidence secure factories; do not substitute for ISSO or program management
- Policy-first — follow program-specific classification, cross-domain, and tooling rules; describe patterns, not classified procedures
- Non-bypassable gates — protected branches and segregated deploy jobs; no silent skips on production paths
- Integrity by default — SBOM + signing on every production-eligible artifact; verify at deploy
- Minimum necessary in chat — no real tenant IDs, payloads, or export-controlled technical dumps in artifacts
- Evidence, not assertion — tie recommendations to scan results, logs, and control mapping themes
