Responsibilities
The DevSecOps Engineer will design and maintain secure CI/CD pipelines with integrated security gates and automated workflows. They are responsible for managing infrastructure-as-code, ensuring configuration compliance, and supporting vulnerability management across hybrid environments.
Requirements
Candidates must have at least ten years of DevSecOps experience, including five years in cybersecurity within large government agencies. A professional certification such as CISSP, IAT III, IAM III, or IASAE III is required, along with the ability to obtain a VA Tier 4 Public Trust clearance.
Full job description
Custom Software Systems, Inc. (CSS) is seeking a DevSecOps Engineer to support our clients' enterprise cybersecurity engineering program. You'll own the secure CI/CD lifecycle and the integration work that wires their cybersecurity tooling into a working, automated pipeline — building the automation, workflow libraries, and telemetry standards that let security scale without adding manual effort. This is hands-on engineering with enterprise scope and a heavy automation-and-integration focus.
Responsibilities
Engineer secure CI/CD pipelines with security gates enforced in the pipeline, and integrate disparate security tooling (SIEM, scanners, ticketing) into automated, orchestrated workflows.
Build and maintain the automation backbone: a version-controlled workflow/SOAR library, engineering runbooks and playbooks, and data-normalization and labeling standards across tools that don't natively agree.
Harden and manage enterprise baseline configurations using infrastructure-as-code and configuration management at scale, with change control that survives an audit.
Produce the recurring engineering deliverables this role owns — integration and schema documentation, monthly tool-optimization reporting, and audit-remediation and requirements-traceability artifacts.
Support continuous security validation, vulnerability management, and incident response across cloud-native and hybrid environments.
Citizenship
· US Citizenship
Required Qualifications
Minimum of ten (10) years of DevSecOps experience
At least five (5) of those ten (10) years in cybersecurity and cloud security at a large government agency comparable in size and scope to VA, DoD, IRS, or GSA.
Secure CI/CD pipeline engineering with in-pipeline security gates; integrating SIEM/scanners/ticketing into automated workflows; infrastructure-as-code and configuration management at scale; and data-normalization/schema work across disagreeing tools.
S.-based; able to obtain and maintain the VA Tier 4 / High Risk Public Trust and PIV.
Certifications
One current certification: IAT III, IAM III, or IASAE III ( CISSP preferred)
