About The Position

As a Staff Mission COMSEC Engineer, you will be the critical technical expert who designs, tests, deploys, and certifies mission-critical cryptographic capabilities for multiple space and ground systems currently in development. This is an ideal role for a security-focused technologist who wants to build encrypted systems from the ground up for cutting-edge space platforms and critical defense programs. This hands-on role requires deep technical expertise across a variety of NSA High Assurance devices securing data-in-transit across actively architected space and ground systems. You will design, deploy, measure, and document technical security methodologies and controls spanning the full mission lifecycle — including satellite operations, ground segments, Command & Control (C2) systems, and mission planning platforms — while supporting the end-to-end journey to Authority to Operate (ATO). You will ensure our systems meet the most rigorous federal security standards while accelerating delivery of critical warfighting capabilities to Department of War and Intelligence Community customers.

Requirements

10+ years in security architecture or encryption engineering, with demonstrated experience designing and deploying cryptographic systems in operational environments
Active Top Secret clearance with SCI eligibility required
DoD 8140 IAT Level III certification (CASP+, CISSP, CISA, or equivalent) required
Experience with TEMPEST requirements and processes, specifically for space systems
Experience with design and successful deployment of NSA Type 1 cryptographic solutions in operational systems
Familiarity with space system architectures including satellite operations, ground segments, and TT&C systems
Excellent communication skills with the ability to articulate security requirements to engineering teams, executive leadership, and government stakeholders
Bachelor's degree in Computer Science, Cybersecurity, Engineering, or related field (or equivalent experience)

Nice To Haves

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
Familiarity with Cross Domain Solutions (CDS), data guards, or other information flow control technologies
Understanding of zero trust architectures and modern identity solutions applied to classified environments

Responsibilities

Lead the engineering design, deployment, testing, and certification of cryptographic systems for space-based assets and ground C2 systems, providing technical leadership to cross-functional engineering teams across multiple product lines
Stay current on emerging technologies relevant to cryptographic product development and implementation
Maintain required documentation for all controlled equipment and keying material (KEYMAT) per USG regulations and best practices
Act as lead architect for resilient and survivable cryptographic security architectures and designs
Work with cross-functional engineering teams through the testing and validation of communication and command links to ensure maximum usability, stability, and system survivability
Conduct and document risk assessments and provide sound mitigation strategies
Identify and remediate findings from STIGs, vulnerability scans, penetration testing, and SCA activities to gain and maintain system Authorization to Operate (ATO)
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
