Clearance Requirement: Ability to obtain and maintain a U.S. Government security clearance; active Secret or higher preferred.

Responsibilities

• Lead end-to-end red team assessments, penetration tests, and threat-informed adversary emulation against authorized space and mission systems.
• Develop assessment plans, attack paths, test cases, and Rules of Engagement that define objectives, authorization boundaries, safety controls, prohibited actions, and stop-work criteria.
• Assess Linux-based systems, embedded devices, flight and payload software, ground-station services, mission networks, cloud environments, and supporting applications for exploitable weaknesses.
• Research and validate vulnerabilities in firmware, operating systems, communications interfaces, authentication flows, APIs, containers, identity services, and other mission-relevant components.
• Create or adapt operator tooling, exploits, proof-of-concept code, automation, and test harnesses to support repeatable assessment objectives.
• Coordinate closely with system owners, engineers, operators, range personnel, and defensive teams to execute testing without unacceptable impact to safety, availability, or mission operations.
• Correlate technical access with realistic mission effects and help customers understand how weaknesses could affect command, telemetry, payload data, availability, or operational trust.
• Document evidence, reproduction steps, attack chains, severity, and prioritized remediation recommendations in clear technical reports and executive briefings.
• Support purple-team validation, detection engineering, remediation retesting, and after-action activities to confirm that identified attack paths have been reduced or closed.
• Mentor operators, contribute to internal tradecraft and lab development, and support technical scoping, customer discussions, and proposal efforts when needed.

Requirements

• Seven or more years of hands-on experience in red teaming, penetration testing, vulnerability research, exploit development, or closely related offensive security work; equivalent military, government, or industry experience will be considered.
• Advanced Linux knowledge, including networking, permissions, services, process behavior, logging, troubleshooting, and security controls.
• Hands-on embedded-systems knowledge, including firmware analysis, boot processes, hardware-software interfaces, common processor architectures, debugging, and at least some exposure to RTOS or embedded Linux environments.
• Practical cloud-security knowledge in at least one major platform such as AWS, Azure, or Google Cloud, including identity and access management, networking, logging, storage, compute, and common misconfiguration paths.
• Experience assessing enterprise networks and applications, including TCP/IP, routing,
