About The Position

We are seeking a passionate Cybersecurity Engineer to join the JETSII Contract, focusing on protecting spacecraft systems, Flight Software (FSW), and embedded hardware architectures. This role involves leading proactive cybersecurity activities, identifying, assessing, and simulating cyber threats against mission-critical space systems. We are looking for a highly motivated professional to contribute to NASA's deep space exploration endeavors and make a difference in understanding the universe.

Requirements

Typically requires a bachelor's degree in Engineering and a minimum of 2- 5 years of experience in the field or in a related area.
Bachelor's degree in Engineering, Cybersecurity, or Cyber Operations.
Experience performing security testing on software, firmware, embedded systems, or mission-critical platforms.
Experience conducting threat modeling and risk assessments for complex systems.
Experience performing vulnerability assessments on critical software and hardware systems.
Experience with embedded software penetration testing, red teaming, or vulnerability research applied directly to aerospace or critical infrastructure platforms.
Demonstrated experience writing custom testing scripts and low-level code (C/C++, Python, Assembly) targeting resource-constrained environments
Strong analytical and problem-solving skills.
Excellent verbal and written communication skills, including the ability to clearly communicate technical findings to both technical and non-technical audiences.
Ability to obtain and maintain a Top Secret security clearance.

Nice To Haves

Experience with spacecraft, satellite, aerospace, defense, or other safety-critical systems.
Experience with Flight Software (FSW) development, testing, or security assessments.
Knowledge of secure software development practices and DevSecOps methodologies.
Ability to work effectively in a cross-functional engineering environment and support multiple projects simultaneously.

Responsibilities

Lead rigorous security testing, threat modeling, and vulnerability assessments targeting Flight Software (FSW) and embedded spacecraft hardware.
Conduct security evaluations to identify and mitigate security weaknesses.
Research advanced spacecraft vulnerabilities and emerging cyber threats affecting spaceflight architectures and embedded systems.
Execute rigorous, non-disruptive penetration testing and red-teaming campaigns targeting the Space Segment (flight software, RTOS, on-board buses), Link Segment (RF telemetry, CCSDS protocols), and Ground Segment (mission control).
Conduct deep-dive "bounty hunting" and vulnerability analysis on third-party software, open-source repositories, and embedded microcode used in safety-critical systems.
Plan and execute interactive Red Team versus Blue Team exercises to validate defensive capabilities and improve cyber resilience.
Collaborate with software, systems, and integration teams to incorporate cybersecurity best practices throughout the development lifecycle.
Document findings, provide risk-based recommendations, and support remediation and mitigation activities.
Perform other duties as assigned.
