Tech Lead, Offensive Security

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

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

Use of AI in hiring

Hadrian uses AI-assisted tools in our recruiting and hiring processes to help our team work more efficiently. This may include tools that help organize and analyze recruiting data, as well as an AI-powered notetaker that can record and transcribe interviews and help coordinate feedback. 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.

Consideration of Criminal History

Hadrian will consider for employment qualified applicants with criminal histories in a manner consistent with the requirements of all applicable laws. We do not ask about criminal history on our application, and we do not consider criminal history before making a conditional offer of employment.
