YOUR MISSION
As a Mission Security Engineer III, you will be a critical technical expert securing national security space systems, classified ground-based Command and Control (C2) infrastructure, and space vehicle hardware and software.
This is a hands-on role that blends deep technical Information Technology (IT) expertise with cybersecurity and compliance acumen. We are looking for candidates with deep expertise in at least one of the following disciplines:
Cybersecurity compliance (NIST 800-53 controls implementation and validation)
DevSecOps
Software Development
Operating systems & hosting (Windows / Linux)
Cloud infrastructure deployment (AWS/Azure)
Containerization infrastructure, Kubernetes, EKS, AKS
Boundary protection
Endpoint Detection and Response / Extended Detection and Response (EDR/XDR)
Security Information and Event Management / Security Operations Center (SIEM/SOC) deployment
You will work as part of a highly capable, cross-functional team to design, deploy, measure, and document classified systems from the ground up — navigating dynamic, cross-program priorities that change daily. You will be responsible for ensuring our systems meet the most rigorous federal security standards while accelerating delivery of critical warfighting capabilities to Department of War and Intelligence Community customers.
This is an ideal role for a security-focused technologist with deep IT or cybersecurity technical skills who is eager to take novel, innovative approaches to cybersecurity and compliance. If you're energized by the challenges of securing mission-critical systems that protect lives and national interests, join our team.

Implement end-to-end security controls for ground-based C2 systems, spacecraft hardware and software platforms, spanning firmware, embedded systems, cloud-native applications, and operational technology
Ensure security architectures enable effective monitoring, logging, and incident response without compromising operational tempo
Implement security controls and zero trust architecture throughout the product development lifecycle, minimizing RMF findings through strong upfront engineering
Implement and validate DISA STIG requirements at the OS, container, platform, and application layers within products as they are developed
Integrate RMF controls into CI/CD pipelines through DevSecOps practices including Infrastructure as Code (IaC), automated security scanning, and continuous monitoring tooling
Identify and remediate findings from STIGs, vulnerability scans, penetration testing, and SCA activities to maintain ATO posture
Support all RMF Steps 1–6, with emphasis on control implementation, assessment preparation, and remediation for DoD and IC programs
Ensure compliance with NIST 800-53, CNSSI 1253, ICD 503, JSIG, and other applicable frameworks for National Security Systems (NSS) handling classified information up to TS/SCI
Support cloud Provisional Authorization (PA) and inherited control models across classified cloud environments (e.g., Impact Level (IL)-6 Cloud Service Providers (CSPs))
Contribute technically to security artifacts including SSPs, SAPs, SARs, and POA&Ms
Serve as a credible technical voice with government ISSOs, ISSEs, and third-party assessors during ATO and reauthorization activities

3–5 years of combined experience in a technical IT field, security engineering, DevSecOps, and/or software development
Active Top Secret clearance with SCI eligibility required
DoD 8140 IAT Level II certification (Security+, CySA+, or equivalent) required
Experience implementing or utilizing NSA Type 1 cryptographic solutions in operational systems
Experience with RMF processes and achieving ATOs for complex systems
Working knowledge of NIST SP 800-53 security controls and how they map to technical implementation
Hands-on experience implementing STIGs at the OS, container, platform, and application level
Familiarity with space system architectures including satellite operations, ground segments, and TT&C systems
Bachelor's degree in Computer Science, Cybersecurity, Engineering, or related field (or equivalent experience)
Preferred Qualifications
Active TS/SCI clearance with polygraph
Direct experience securing C2 systems, space systems, or other DoD mission systems
Experience supporting DoD or IC customers through ATO, re-ATO, or continuous authorization
Direct experience within IL-5 or IL-6 impact level cloud environments
Knowledge of cloud security control inheritance and shared responsibility models within DoD IL-5 or IL-6 environments
Familiarity with Cross Domain Solutions (CDS), data guards, or other information flow control technologies
Experience with FedRAMP High, CMMC, or DoD IL-5/IL-6 authorizations
Experience integrating security tooling (e.g., SIEMs, vulnerability scanners, audit/logging systems) into development workflows
Understanding of zero trust architectures and modern identity solutions applied to classified environments
Work Environment
This role will be onsite in Denver, CO (preferred) or Long Beach, CA #LI-Onsite
Fast-paced, mission-critical environment supporting national security space operations
Requires coordination across distributed teams including spacecraft engineers, ground operations, and government partners
May require participation in on-call rotation for security incident response and mission-critical system support
High degree of autonomy and ownership as a trusted, cleared team member
Occasional travel to government sites, launch facilities, or partner locations may be required
