Overview & Responsibilities
Join our client as a Senior Systems Architect & Integration Engineer supporting the Department of Defense (DoD) and Air Force at the heart of national security. In this long-term role, you won’t just maintain systems – you will bridge the gap between complex Intelligence, Surveillance, and Reconnaissance (ISR) data and the warfighter. You will design, integrate, and secure the next generation of targeting and collection management solutions using modern DevSecOps and cloud-native architectures. You will…

• Lead the high-level solution architecture for complex ISR and Targeting systems, ensuring they are scalable, resilient, and aligned with Air Force mission objectives.
• Design and implement robust, secure API-based integrations to connect disparate DoD data sources, ensuring seamless interoperability across the enterprise.
• Architect and manage diverse data environments, utilizing both RDBMS and Polyglot (NoSQL) database solutions to handle high-velocity mission data.
• Oversee the deployment and orchestration of containerized applications using Kubernetes, ensuring a secure and automated CI/CD pipeline from development to production.
• Proactively identify and remediate vulnerabilities using tools like Fortify; ensure all solutions meet rigorous DoD cybersecurity standards and Risk Management Framework (RMF) requirements.
• Apply Design Thinking and agile methodologies to lead technical workstreams, translate mission requirements into engineering specifications, and mentor junior staff.
• Identify opportunities to leverage AI/ML (including Gemini and LLMs) to automate collection management and enhance decision-making for ISR analysts.

Required Qualifications

• Must be a U.S. Citizen with an active TS/SCI clearance.
• 10+ years of post-degree, paid professional engineering experience (excluding internships).
• Bachelor’s degree in Engineering, Computer Science, Math, Physics, or Chemistry.
• Expertise in Object-Oriented Design (OOD) and System Integration.
• Hands-on experience with Kubernetes and DevSecOps workflows.
• Deep knowledge of SQL and at least one NoSQL database platform (i.e. MongoDB Enterprise, Couchbase Server, MarkLogic, Apache Cassandra / DataStax, Apache HBase, ScyllaDB, Redis, Amazon DynamoDB, Amazon Neptune, Neo4j, Elasticsearch (ELK Stack), ArangoDB).
• Proficiency in Microsoft Office Suite for technical reporting and briefings.

Preferred Qualifications

• Prior experience in the US Armed Forces (any rank/branch).
• Specific domain knowledge in ISR (Intelligence, Surveillance, and Reconnaissance), Targeting, or Collection Management.
• Familiarity with Cyber Scan tools like Fortify.

Terms of Employment

• Full-Time, Permanent
• Work Schedule: Onsite (4 days/week), Remote (1 day/week), Travel (1 day every 2-3 weeks to Warrenton, VA)

Overview & Responsibilities
We are seeking a high-level Linux Systems Subject Matter Expert to provide technical leadership and advanced engineering support for mission-critical environments. This role is not merely about maintenance; it requires a deep-tier specialist capable of kernel-level tuning, performance optimization, and the integration of Dassault Systèmes Cameo (No Magic) suite within a secure, multi-site architecture. The successful candidate will be the primary technical authority for Linux-based infrastructure, ensuring high availability and peak performance for complex modeling and simulation workflows. You will…

• Perform deep-dive troubleshooting and performance optimization using CLI-level mastery. This includes kernel parameter tuning, memory management optimization, and I/O scheduling to support data-intensive MBSE tools.
• Support and optimize the Cameo Systems Modeler (and associated No Magic products) environment. This includes managing Teamwork Cloud (TWCloud) deployments, coordinating updates, and ensuring seamless integration with underlying Linux distributions.
• Develop sophisticated scripts (Bash, Python, or Ansible) to automate repetitive tasks, hardening procedures, and environment provisioning.
• Maintain rigorous security standards in accordance with TS/SCI protocols. Apply STIGs (Security Technical Implementation Guides) and manage RMF (Risk Management Framework) requirements without compromising the performance of the Cameo environment.
• Act as the technical bridge between the Ft. Washington and Warrenton facilities, ensuring configuration parity and reliable data synchronization across geographically dispersed nodes.

Required Skills & Qualifications
Expert-Level Linux Administration

• Extensive experience in a “headless” environment. You should be comfortable navigating complex filesystems, managing processes, and debugging network stacks exclusively via the command line.
• Proven ability to modify kernel parameters (sysctl), manage modules, and optimize the OS for specific application workloads (e.g., database performance for TWCloud).
• Expertise in LVM, NFS, and encrypted storage solutions (LUKS) within a Linux context.

Dassault Systèmes / Cameo Experience

• Hands-on experience with Cameo Systems Modeler, Teamwork Cloud, and Cameo Collaborator.
• Knowledge of the Java Virtual Machine (JVM) tuning required to keep Cameo/MagicDraw running efficiently under heavy model loads.
• Understanding of the licensing servers (FlexNet/FlexLM) associated with Dassault products.

Security & Clearance

• Must possess an active Top Secret clearance with SCI eligibility (Active TS/SCI is highly preferred).

Preferred Qualifications

• Experience with RHEL/CentOS or Rocky Linux in a secure government environment.
• Background in Model-Based Systems Engineering (MBSE) workflows.
• Experience with containerization (Docker/Podman) or orchestration (Kubernetes) for deploying No Magic services.
