Senior Cybersecurity Engineer with Security Clearance

Position Overview:
We are seeking a mission-driven Senior Cybersecurity Engineer to support the development, integration, and protection of advanced space-based defense systems. The ideal candidate will have a strong background in cybersecurity engineering within DoD environments, with direct experience applying RMF processes, conducting risk assessments, and securing complex, multi-domain systems-especially those aligned with SDA or USSF missions. This role requires proactive problem-solving, deep technical expertise, and the ability to work cross-functionally with engineers, program managers, and security teams. Key Responsibilities:
Design and implement secure architecture solutions for terrestrial and space-based systems. Lead cybersecurity efforts in support of system development, testing, and deployment. Apply RMF (Risk Management Framework) to obtain and maintain system ATOs. Conduct vulnerability assessments and support mitigation planning using tools like ACAS, Nessus, STIGs, and SCAP. Develop and maintain cybersecurity documentation, including SSPs, POA&Ms, and CONOPS. Perform security engineering analysis on emerging technologies, including satellite communications, mesh networks, and edge computing. Collaborate with cross-functional teams to integrate security into all phases of the system lifecycle. Support security audits, assessments, and incident response efforts as needed. Required Qualifications:
Active DoD Secret Clearance (TS/SCI preferred or must be eligible). Bachelor's degree in Cybersecurity, Computer Science, Information Assurance, or related field (or equivalent work experience). 7+ years of cybersecurity engineering experience, preferably in a DoD or defense aerospace environment. Deep knowledge of RMF, NIST 800-53, STIGs, and DISA compliance tools. Familiarity with DoD systems engineering lifecycle and security accreditation processes. Proficient in vulnerability management, incident response, and network hardening. Excellent technical writing and documentation skills. DoD 8570 IAT Level II or III certification (e.g., Security+, CASP+, CISSP, CISM). Preferred Qualifications:
Prior experience supporting SDA, USSF, MDA, or similar space-focused DoD programs. Experience securing space systems, embedded systems, or satellite ground stations. Hands-on experience with SIEM platforms (e.g., Splunk, ELK), endpoint protection, and Zero Trust architectures. Experience with DevSecOps pipelines, container security, or cloud (AWS GovCloud/Azure IL5) environments.
