Job description

At Intelliforce, we work on the kinds of security problems where deep technical skill directly supports mission success. In this role, you will join the team as a senior CNO Vulnerability Researcher, focused on finding software vulnerabilities, reverse engineering complex systems, and helping drive security research that matters in real operational environments. This is a strong fit for an engineer who likes hard targets, low-level problem solving, and technical work that pushes past the obvious.

What Makes This Opportunity Stand Out

This role gives you the chance to work at the sharp end of vulnerability research while also helping lead projects and mentor others. You will research vulnerabilities, reverse engineer software to bypass security mechanisms, support user land and kernel development efforts, and stay current on the tools and techniques shaping modern security research. The work is technical, mission-driven, and broad enough to keep the job interesting, especially for someone who enjoys both hands-on research and helping guide a team.

At Intelliforce, your work is visible and your expertise matters. Because we support prime programs, our teams stay close to meaningful mission work with real momentum. Because we are a small business, leadership is accessible, communication is direct, and strong technical contributions get noticed. Add in long-term stability, strong benefits, and a people-first culture, and this becomes more than another vulnerability research role. It is a chance to do serious technical work with real mission impact.

Day‑to‑Day Responsibilities

• Research and discover software vulnerabilities across mission-relevant targets
• Reverse engineer software to identify security mechanism bypasses and other weaknesses
• Lead projects when needed and help guide technical direction across the team
• Assist with the design, development, documentation, testing, and debugging of user land and kernel software and systems
• Stay current on tools, techniques, countermeasures, and trends in computer network vulnerabilities, static and dynamic program analysis, network security, and encryption
• Communicate status clearly to leadership and stakeholders
• Supervise and mentor subordinate project staff and collaborative technical teams

Minimum Qualifications

• Clearance: Top Secret Clearance with Polygraph, must be active. We do not have the ability to sponsor clearances
• Citizenship: Must be a U.S. Citizen. We cannot sponsor visas
• Bachelor’s degree and 12 or more years of experience
• Or High School diploma and 16 or more years of experience
• Or Associate’s degree and 14 or more years of experience
• Or Master’s degree and 10 or more years of experience
• Or PhD and 8 or more years of experience
• 7 years of position-specific relevant experience
• Experience in vulnerability research
• Current active TS/SCI with Polygraph required

Required Skills

• Experience in vulnerability research
• Experience in reverse engineering and common security research tools such as IDA Pro, Ghidra, Radare, Binary Ninja, SysInternals, GDB, and WinDBG
• Proficiency in Python, C, C++, or Assembly for x86 or x64
• CNO capability development experience
• Proficiency with low-level internals in one or more technology areas such as Windows, Linux, or Mobile
• Strong troubleshooting and debugging experience
• Ability to communicate clearly with leadership and technical teams
• Ability to mentor and supervise junior staff when needed

Desired Skills

• Degree in Computer Science or a related technical field
• 9 years of position-specific relevant experience
• Experience leading technical security research efforts
• Strong background in low-level software analysis across multiple operating environments

Benefits

• Ample PTO to rest and recharge—plus all federal holidays and your birthday off, just because
• Multiple medical plan options, including ones with zero deductible or premium for employees
• Generous 401(k) with immediate vesting—because your future matters now
• Exciting bonus opportunities, from profit sharing to quarterly awards and President’s Club recognition
• A culture of collaboration, connection, and fun, with regular team activities that go beyond the work
