L3Harris is seeking a highly qualified Information Security Systems Engineer (ISSE) with strong cloud security expertise to join the Network Security Engineering Team supporting secure managed network and cloud solutions for federal government and enterprise customers.

The ideal candidate is a technically strong ISSE with demonstrated AWS security experience, capable of designing, implementing, and putting into operation, security controls across cloud-native applications and infrastructure. This role partners closely with Engineering, DevOps, and Architecture teams to embed security throughout the Software Development Lifecycle (SDLC), automate controls within CI/CD pipelines, and ensure alignment with industry standards and regulatory requirements. The successful candidate will bring hands-on experience securing AWS environments and integrating DevSecOps practices to deliver scalable, resilient, and compliant cloud capabilities.
  • This is a 100% onsite position at L3Harris offices located in Melbourne, Florida and cannot be performed remotely.

  • Design and secure AWS cloud and hybrid architectures, including IAM, VPC networking, containers (EKS/ECS/Fargate), and serverless (Lambda), aligned to Zero Trust principles.
  • Integrate security into Agile development and SDLC processes by defining cybersecurity requirements, implementing secure coding practices, and deploying application security controls (SAST, DAST, SCA, container scanning, API security).
  • Automate and enforce security controls within DevSecOps pipelines using Infrastructure-as-Code (Terraform, CloudFormation), policy-as-code, and CI/CD platforms (GitHub, GitLab, Jenkins, CodePipeline).
  • Implement and manage cloud-native logging, monitoring, and detection capabilities (CloudTrail, GuardDuty, Security Hub, Config) and support incident response and automated remediation.
  • Support compliance and risk management initiatives (NIST 800-53, ISO 27001, SOC 2, FedRAMP, GDPR) through secure baseline management, control implementation, and remediation tracking.
  • Collaborate with Systems Integration & Test (SI&T) and cross-functional engineering teams to validate security controls and maintain required documentation.

Qualifications:
  • Bachelor's degree with a minimum of 4 years of relevant experience, or a Graduate degree with 2 years of relevant experience. In lieu of a degree, 8 or more years of directly related experience will be considered.
  • Experience with hands-on AWS security experience (IAM, KMS, Secrets Manager, VPC architecture, encryption in transit/at rest).
  • Experience in network and platform security.
  • Experience securing containerized environments (Docker, Kubernetes) and implementing DevSecOps practices within CI/CD pipelines.
  • Strong scripting and automation skills (Python, Bash, PowerShell) with Git-based version control experience.

Preferred Additional Skills:
  • Experience operationalizing security automation to support continuous monitoring, vulnerability management, and compliance validation.
  • Strong knowledge of secure architecture principles, networking technologies, Zero Trust, and SASE models.
  • Experience securing enterprise infrastructure within regulated environments (e.g., Government, Financial Services, Healthcare), including NIST and FISMA compliance.
  • Expertise in threat modeling, risk analysis, and cross-functional collaboration with engineering and executive stakeholders.
  • Relevant certifications such as AWS Certified Security - Specialty, AWS Certified Solutions Architect - Professional, CISSP, CCSP, CSSLP, CCNA, CCNP, CompTIA Security+, or equivalent credentials.
