Role Description

LMI is seeking an experienced Security Lead to support a key client at the General Services Administration (GSA) in delivering a modern, web-based acquisitions system. This initiative modernizes Governmentwide Indefinite Delivery Vehicle (IDV) contracting through modular, API-driven services deployed in federal cloud environments.

The Security Lead will serve as the senior authority responsible for defining and enforcing the program’s security and compliance approach in alignment with GSA requirements. This individual must possess a comprehensive understanding of the Authorization to Operate (ATO) process for cloud applications and collaborate closely with the client’s Information Technology Security Officers (ITSOs) to ensure the development team adheres to approved security controls and compliance standards.

The ideal candidate combines deep federal security expertise, hands-on cloud security experience in AWS, and the ability to integrate DevSecOps practices into modern Agile software delivery. This position is anticipated to be majority remote, but with the ability to travel and visit the client’s offices in Washington, D.C. as frequently as needed.

  • Embed automated security controls into CI/CD pipelines to enable secure, continuous delivery
  • Ensure static and dynamic code analysis, dependency scanning, container security, and infrastructure-as-code validation are integrated into build and deployment processes
  • Promote secure coding practices and continuous monitoring across development teams
• Cloud Security (AWS)
  • Lead security architecture for applications and infrastructure deployed within AWS cloud environments
  • Configure and manage native AWS security services (e.g., IAM, Security Hub, GuardDuty)

Qualifications

• Demonstrated experience serving as a Security Lead (or equivalent role) on federal IT programs
• Extensive hands-on experience implementing federal security architectures aligned with NIST guidance, FedRAMP, and TIC/cloud security requirements
