Job summary

Apex, based in Playa Vista, CA, seeks a Senior Red Team Engineer to attack our spacecraft, ground systems, and related software from an adversary perspective. You will lead internal assessments, coordinate with external firms, and develop testing tools to ensure security across the development pipeline.

This hands-on role focuses on active security testing, not audits or policy work, and you will collaborate with the Product Security Architect and embedded security teams to harden designs from

Responsibilities

• Plan and run adversary emulation against our spacecraft, flight software, ground systems, and development pipeline, using SPARTA and MITRE ATT&CK to structure the work.
• Look for attack paths that cross system boundaries, such as a ground-system compromise that leads to control of a spacecraft, instead of testing each component in isolation.
• Lead our third‑party security assessments: set the scope, give the testers the environments and engineering support they need, and bring their results together with our own.
• Design and build our fuzzing and automated testing capability, including agent‑driven test generation, so testing runs with every release and not just once a year.
• Reverse engineer firmware and protocols, analyze embedded hardware interfaces, and review how cryptography is implemented.
• Join design reviews and technical trade‑offs to show how a proposed design could be attacked before it is built.
• Co‑chair our product security incident response process, helping triage reported vulnerabilities and coordinate fixes.
• Work with engineering teams to fix the root causes of what you find and help other engineers learn to think like attackers.
