Job Description

This position is for a Window’s CNO Developer position. Applicants should have an understanding of Windows Operating System internals, including using the Windows API and both documented and undocumented Windows Kernel data structures. As a Windows CNO Developer, you develop capabilities in support of operations. Your primary focus will be developing tools that work in both user and kernel space. You will play a crucial role in developing custom capabilities used on live systems. You will be a key player supporting national security interests.

This position requires a TS/SCI clearance. Cohere will sponsor qualified individuals on a case by case basis.


When assessing candidates for the CNO Developer position, Cohere is looking for candidates with the following knowledge, skills, and abilities:

Coding – Candidates should be able to demonstrate extensive experience coding in C/C++ and Python, including understanding Object Oriented Programming, Networking (sockets), Multithreading, and implementing cryptographic protocols for data at rest and data in transit. You should be capable of developing technical solutions to complex problems.

Exploitation – You should have expertise in a wide range of techniques, including stack and heap attacks such as buffer overflows, off by one vulnerabilities, memory leaks, and format string attacks, and understand how to bypass protections like stack canaries, DEP, K/ASLR, CFG, KPP, SMEP/SMAP.

Reverse Engineering – you should be experienced using RE tools including both debuggers and disassemblers. You should be capable of automating the analysis of binaries.

Creative Thinking – as Operating Systems evolve, tools that worked before might not work in the future. We need team members who are driven to learn and excited about solving hard problems who can adapt to changing environments.

Communication – Just as important as your technical skills, as a Subject Matter Expert, you are expected to advise and assist the other teammates. This requires being able to clearly break down and explain complex techniques to others.

Collaboration – You should know how to use a version control system and CI/CD tools, preferably git or gitlab.

Leadership – You may function in a project leadership role, and you should be comfortable leading small teams.
