Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.

For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.

Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.

We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

    • Monitor & assist in compliance with standards such as NIST SP 800-53/171, FISMA, DoD directives, or equivalent frameworks such as ISO 27001, and drive remediation efforts for any identified vulnerabilities.

    • Foster a collaborative team environment, providing guidance and mentorship to junior staff on ComSec and ATO best practices.

    • Evaluate project outcomes through post-implementation reviews, capturing lessons learned to improve future processes.

    • Assist in managing or collaborating on other IT & Cybersecurity projects.

    Requirements:

  • • Bachelor's degree in Information Technology, Cybersecurity, Project Management, or a related field; Master’s degree preferred; Certification is a plus.

    • Minimum of 5 years of experience in project management, with at least 3 years focused on cybersecurity, ComSec, or ATO processes in regulated industries (e.g., government, defense, or finance).

    • Strong understanding of cybersecurity frameworks, including NIST RMF, FedRAMP, DISA, and DoD Instruction 8510.01.

    • Proficiency in project management methodologies (e.g., Agile, Waterfall) and tools for tracking progress and risks.

    • Knowledge of ComSec principles, including encryption standards, secure hardware (e.g., TEMPEST), and communication security policies.

    • Excellent communication and interpersonal skills, with the ability to translate technical concepts to non-technical stakeholders.

    • Proven ability to manage multiple projects simultaneously in a fast-paced environment, with strong problem-solving and decision-making capabilities.

    • Experience with risk assessment tools, vulnerability scanning, and compliance auditing.
