Job summary

Apex is seeking a senior Red Team Engineer to attack its spacecraft, flight software, ground systems, and development pipelines. You will run internal assessments, lead external firms, and build testing tools to pressure- test designs from early in the development cycle.

The role emphasizes hands-on security work across aerospace products, working with the Product Security Architect and embedded security teams to identify and mitigate risks before deployment.

Qualifications

• 3-10 years of hands-on offensive security experience in penetration testing, red teaming, exploit development, or vulnerability research.
• Track record of building your own tools, harnesses, or automation when nothing off the shelf would do the job.
• Experience combining several smaller weaknesses into a realistic attack path.
• Solid fundamentals in operating systems, networking, and applied cryptography, and comfort reading and debugging code you have not seen before.
• Ability to own a technical project from start to finish with little direction.
• Clear communication, whether walking an engineer through a fix or explaining risk to leadership.

Responsibilities

• Plan and run adversary emulation against spacecraft, flight software, ground systems, and development pipeline using SPARTA and MITRE ATT&CK.
• Identify cross-system attack paths that cross boundaries between components.
• Lead third-party security assessments: scope, environments, support, and results integration.
• Design and build fuzzing and automated testing capabilities for every release.
• Reverse engineer firmware and protocols, analyze embedded hardware interfaces, and review cryptography.
• Join design reviews to show how a design could be attacked before build.
• Co-chair product security incident response and coordinate fixes.
• Work with engineering to fix root causes and train others to think like attackers.
