Two Six Technologies is seeking a Principal Firmware Reverse Engineer. You will work with a range of clients supporting national security missions. You will become a trusted advisor while learning and performing valuable technical and industry skills. This role is technical at its core – along with in-depth reverse engineering and exploit development you will transition those findings into capabilities.

Job Responsibilities & Duties
Given the technical nature of this role, experience in computer science, computer engineering, or a similar field is required. Significant proven experience in reverse engineering (RE) or vulnerability research (VR) can show your fit even if your background is outside of one of these fields.

You should be comfortable taking on complex technical problems for which there is often no known answer. You should be comfortable with ambiguity and forging your own path; our small team setting will provide you opportunity for outsized impact. While you will receive extensive training, mentorship, and coaching, you must be comfortable executing against goals independently since there’s no playbook for breaking unique complex systems.

Qualifications & Skills- Required:

  • Bachelor’s (or higher) degree in computer science, engineering, or a related field (solid knowledge in RE or VR may substitute for a specific degree)
  • Minimum 5 years of experience firmware development using low-level programming languages (C and at least one assembly language), scripting languages (e.g., Python), and the *nix command line
  • Strong familiarity with cybersecurity principles and a strong interest in learning more
  • Minimum 5 years of experience with common disassemblers/decompilers and reverse engineering tools (IDA, Ghidra, Binary Ninja)
  • Experience with software reverse engineering concepts: static analysis, dynamic analysis, fuzzing techniques
  • Experience providing technical/functional direction and developing techniques to implement, ensuring customer satisfaction.
  • Experience leading a small technical team of engineers and researchers
  • Active Top Secret clearance
  • Must be willing to obtain and maintain a SCI & Polygraph clearance

Nice to have, but not expected:

  • Familiarity with Binary Ninja API or Ghidra scripting
  • Familiarity building or securing embedded devices and other digital systems
  • Familiarity with embedded binary reverse engineering (ARM, RTOS, etc.)
  • Familiarity with basic cryptography design and implementation concepts
  • Experience in a client-facing technical role
  • An active Top Secret DoD or IC security clearance

Clearance Requirements:

  • Active Top Secret clearance, and ability to obtain a Polygraph

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.


Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
