Two Six Technologies is actively seeking a Principal Cybersecurity Researcher to join our team in Arlington, Virginia. The team is composed of intelligent individuals, passionate about reverse engineering, vulnerability research, and low-level programming. The team is growing and looking for someone with an advanced technical background that has an understanding on how to solve complex challenges and inspire creativity to address a wide range of difficult problems. If you are actively using reverse engineering and vulnerability research tools and frameworks, the team wants to talk to you!

What you will do:

  • Lead the technical planning and execution of projects in reverse engineering and vulnerability research, including task coordination, deliverables, and alignment with customer objectives.

  • Author detailed technical documentation, proposal sections, and white papers to communicate research findings and technical solutions to internal teams, stakeholders, and external audiences.
  • Provide direction and develop differentiated technical approaches to ensure customer satisfaction and support ongoing business development opportunities.

What you will need (basic qualifications):

  • Demonstrated expertise in advanced cybersecurity research concepts typically acquired in a similar technical role.
  • Expert-level proficiency in two or more of the following: low-level programming (C/C++, Assembly) and the use of industry-standard disassemblers and decompilers, binary re-hosting frameworks to enable dynamic analysis, and building custom greybox/blackbox fuzzing harnesses.
  • Proven experience in vulnerability research, including attack surface triage, identifying vulnerabilities, and developing proof-of-concept exploits to demonstrate security impact.
  • Extensive experience in technical mentorship and training, with a history of providing thorough solutions to complex problems and guiding less experienced team members.
  • Experience leading complex technical projects in reverse engineering/vulnerability research or R&D for National Security customers.
  • Experience delivering high‑quality technical documentation, such as vulnerability research and findings, industry white papers, and competitive proposals, that distills complex cybersecurity concepts for diverse audiences.
  • Experience in a client-facing technical role, demonstrating strong communication and stakeholder management skills.

Nice to have (preferred):

  • Master’s or PhD in Computer Science, Engineering, or a related technical specialty area.
  • Experience leading technical sections for multi-million-dollar proposals or contributing white papers to support business capture efforts.
  • Experience with embedded systems reverse engineering (e.g., ARM/MIPS architectures, RTOS, bare-metal environments) or cryptographic design principles.
  • Experience with custom fuzzing harness development, binary re-hosting, or accelerated RE/VR tooling.
  • Recognized participation in the external technical community (e.g., presentations, panels, or professional associations).

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
