Role Description

LMI, a trusted government contractor with decades of experience delivering cutting-edge solutions, is seeking a driven and innovative Platform Engineer to support the deployment and maintenance of IronSled, a DevSecOps product tailored for government-authorized environments. This position requires an active Secret clearance and can be performed remotely or hybrid (with occasional on-site work in government-authorized environments).

  • Develop, enhance, and operationalize the IronSled platform to enable secure software delivery at scale.
  • Design, deploy, and maintain cloud and on-premise infrastructure solutions compliant with federal security standards (e.g., FedRAMP High, NIST 800-53).
  • Build and optimize IronSled’s platform features for usability, reliability, and security.
  • Develop, integrate, and maintain CI/CD pipelines with security automation processes.
  • Operate and troubleshoot platform services for high availability and performance.
  • Collaborate with cybersecurity teams to align infrastructure and application configurations with government security requirements.
  • Implement observability tools and dashboards for real-time monitoring of platform health and security compliance.
  • Partner with developers, security specialists, and client stakeholders to deliver secure solutions.
  • Create comprehensive documentation for technical processes and operational procedures.

Qualifications

  • 5+ years of experience as a platform engineer, DevSecOps engineer, systems administrator, or similar role.
  • Experience managing both cloud (e.g., AWS GovCloud, Azure Government) and on-premise environments.
  • Active Secret clearance required.
  • Expert-level proficiency in cloud platforms like AWS, Azure, GCP, or other government-authorized providers.
  • Strong knowledge of container orchestration tools (e.g., Kubernetes, OpenShift).
  • Hands-on experience with Infrastructure as Code (IaC) tools (e.g., Terraform, Ansible, CloudFormation).
  • Familiarity with secure CI/CD pipelines (e.g., GitLab, Jenkins, CircleCI) and security automation tools (e.g., SonarQube, Aqua Security, Twistlock).
  • Knowledge of network security, identity management (e.g., IAM, RBAC), and secure communications protocols (e.g., TLS/SSL).
  • Understanding of FedRAMP High, NIST 800-53 frameworks, and other government security requirements.
  • Experience with accreditation and audits for classified or regulated environments.
  • Strong collaboration skills with cross-functional teams.
  • Effective communication and documentation skills for technical processes.

Requirements
