What You’ll Do
Build and run Hadrian’s offensive security function: red-team operations, penetration testing, and adversary emulation across software, robotics/OT, cloud, and physical devices.
Perform reverse engineering and vulnerability research on firmware, embedded controllers, and third-party components in our manufacturing environment.
Develop AI-driven offensive tooling to scale coverage, and assess the security of Hadrian’s own AI and autonomy systems.
Drive findings to remediation with engineering and the blue team, run purple-team exercises, and measure risk reduction over time.
Represent Hadrian’s security posture to customers, auditors, and DoD stakeholders.
What We’re Looking For
Deep, hands-on red-team and penetration-testing experience at a top-tier engineering organization (e.g., Block, Stripe, Anthropic, Google, AWS).
Strong reverse engineering skills (Ghidra, IDA Pro, or Binary Ninja) and a track record of finding and weaponizing real vulnerabilities.
Proficiency building offensive tooling in Python, Go, or C/C++ and leveraging AI to accelerate offensive work.
Ability to operate fully autonomously — set strategy and own outcomes without a team beneath you at the start.
Must be a U.S. person under ITAR (see requirements below).
What Will Set You Apart
Hardware, embedded, or OT/ICS security experience (JTAG/UART, firmware extraction, industrial protocols).
Recognized external presence — talks at DEF CON, Black Hat, or Recon, and published research or CVEs.
Experience attacking or securing AI and agentic systems.
Background in aerospace, defense, robotics, or manufacturing.
Experience standing up a red team or offensive program from zero.

USE OF AI IN HIRING

These tools support our team and are not used to make hiring decisions. All candidate evaluations and hiring decisions are performed by humans. If an interview will be recorded, you will be notified in advance and may opt out at any time with no impact on your candidacy. Candidate data processed through these tools is subject to the same protections described in our Privacy Policy https://www.hadrian.co/privacy-policy.
