Red Team Engineer, Product Security

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.
Responsibilities:
•
This is a hands-on engineering role, not an audit, compliance, or security policy role.
•
About the Team
•
Apex builds spacecraft, the flight software that runs them, the ground systems and cloud software used to command them, and the test equipment and emulators used to develop them. In this industry a security failure can cost an entire mission, so we try to find the weaknesses before anyone else does.
•
Product Security is a small team with a big footprint. You would be its second core member, working directly with the Product Security Architect and alongside security engineers embedded in our flight software, ground software, and development infrastructure teams.
•
- 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.
Requirements:
•
- US Citizenship
•
- 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.
•
- Experience with embedded or cyber-physical systems in space, aerospace, automotive, robotics, industrial/OT, medical devices, or autonomous vehicles.
•
- Experience building fuzzing harnesses for embedded or protocol targets, and working with RTOS, embedded Linux, or hardware interfaces such as JTAG, SWD, SPI, I2C, or CAN.
•
- Experience with AI-assisted security testing.
•
- Familiarity with RF and satellite command links, GNSS spoofing and jamming, or ground station architecture.
•
- Experience scoping or directing the work of outside assessment firms.
