Full Job Description
The Role:

As our Tech Lead overseeing Offensive Security, you will build and lead Hadrian's offensive security capability from the ground up. Hadrian's software-defined, ITAR-controlled factories are a high-value target, and your job is to find what an adversary would find first - across our manufacturing software, robotics and OT, cloud, corporate systems, physical devices, and AI. This is a hands-on principal role for someone who has done elite red-team work and wants to own an entire offensive function.

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.


Benefits for Full-time Employees
  • Medical, dental, vision, and life insurance plans for employees
  • 401k
  • Relocation support may be provided for certain situations, based on business need.
  • Flexible vacation policy
  • Equity

About Hadrian

Hadrianadri?ja?n?s]; 24 January 76 – 10 July 138) was Roman emperor from 117 to 138. He was born in Italica, a Roman municipium founded by Italic settlers in Hispania Baetica and he came from a branch of the gens Aelia that originated in the Picenean town of Hadria, the Aeli Hadriani. His father was of senatorial rank and was a first cousin of Emperor Trajan. Hadrian married Trajan's grand-niece Vibia Sabina early in his career before Trajan became emperor and possibly at the behest of Trajan's wife Pompeia Plotina. Plotina and Trajan's close friend and adviser Lucius Licinius Sura were well disposed towards Hadrian. When Trajan died, his widow claimed that he had nominated Hadrian as emperor immediately before his death. Rome's military and Senate approved Hadrian's succession, but four leading senators were unlawfully put to death soon after. They had opposed Hadrian or seemed to threaten his succession, and the Senate held him responsible for their deaths and never forgave him. He earned further disapproval among the elite by abandoning Trajan's expansionist policies and territorial gains in Mesopotamia, Assyria, Armenia, and parts of Dacia. Hadrian preferred to invest in the development of stable, defensible borders and the unification of the empire's disparate peoples. He is known for building Hadrian's Wall, which marked the northern limit of Britannia.
