Spectral is a seven-year $1.2B program to provide the U.S. Navy’s next‑generation signals intelligence, electronic warfare, and information operations software technologies. The Spectral system is critical to the ability for our forces to fight and win in the increasingly sophisticated and complex cyber and electronic threats of our adversaries.

We are seeking someone with technical experience who is highly skilled in cyber engineering to be responsible for toolset design, implementation, automation, and optimization of Spectral enterprise‑wide security solutions. Desired cyber engineering skillsets will be responsible for continuous development of secure software solutions and hardened mission applications.

The ideal candidate brings hands‑on cyber engineering experience with cyber analytics and reverse engineering tactics on Kubernetes infrastructure, who thrives in fast‑paced, complex environments, and has a proven track record of technical advancements in cyber engineering, cybersecurity engineering, analysis, and modern software deliverables.

Responsibilities

• Automate cybersecurity architecture within the infrastructure as code (IaC) for on‑prem and distributed platforms and mission applications with end‑to‑end integrated Zero Trust capability to deliver high quality software outcomes.
• Engineer and integrate security controls into the IaC, platform as a service (PaaS), and mission applications to automate and streamline outputs for IAM, encryption, logging, and monitoring compliance validation.
• Streamline hardening of IaC, PaaS, and mission applications leveraging STIG/SRGs, CIS benchmarks, and industry best practices.
• Support secure software deployments, containerized platforms and mission applications.
• Coordinate and engineer cybersecurity tools pipeline integration, enforcement, and automate tool outputs into dynamic decision‑making dashboards.
• Engineer and automate RMF security control implementation into the IaC, PaaS, and mission applications to modernize and rapidly produce body of evidence for continuous delivery, monitoring, updates, and improvements.
• Modernize vulnerability remediation outcomes and engineer continuous system resiliency, adaptability, drift correction, and responsiveness to updates.
• Write Ansible playbooks and scripts and perform peer review of cyber engineer as well as software developer code commits.
