Vulnerability Researcher

Company Overview
CCG is a technology company focused on equipping customers with the capabilities and support to conduct intelligent and successful cyber operations. We do this by finding the most talented engineers and operators in the country, give them some of the most challenging problems facing the US government, and help them unleash their creativity and problem-solving skills. Excellence is our standard and mission success is our metric. 
Role As a member of the Security Research team, you will imagine weaknesses in multiple types of systems and then find, demonstrate/document, and exploit those weaknesses. You will be joining a team of mature and extremely competent Security Researchers to breakdown and fully understand how a host of different systems function. You will need to leverage extensive experience performing static and dynamic analysis and must be familiar with multiple classes of vulnerabilities. Additionally, you must be extremely comfortable communicating with team members, technical partners, and non-technical partners alike. The ideal candidate will be comfortable and confident operating at the early phases of a vulnerability research project and have the mettle to see the project through to multiple phases and iterations.    Responsibilities

• Perform vulnerability research and reverse engineering for customer tasks 
• Perform static and dynamic analysis by applying research tools such as disassemblers, debuggers, and fuzzers
• Perform exploit development which leverage discovered vulnerabilities 
• Be able to communicate security research findings internally and, when and where it is appropriate, externally

Minimum Qualifications

• Must possess a TS clearance
• Bachelors degree in Computer Engineering, Computer Science, Software Engineering, or a related technical discipline. Degree requirement can be met with four years of hands on experience in a software engineer or similar full time position
• 3+ year(s) of experience in software vulnerability research
• Experience with Ghidra, Binary Ninja, IDA or other reverse engineering/disassembler tools
• Experience working in Linux fundamentals (strong grasp of sockets, file descriptors, networking, iptables, file systems, kernel, etc.)
• Ability to read and write C and assembly languages as needed (ARM, MIPS, x86_64) with minimal oversight or supervision
• Strong programming fundamentals; particularly with networking, data structures, and data models
• Understanding of exploitation techniques such as leveraging arbitrary read-write primitives, shellcoding, and return-oriented programming / jump-oriented programming

Preferred Experience

• OS and kernel reverse engineering 
• Understanding of fuzzers such as AFL++ or libfuzzer
• Understanding of common exploit mitigation mechanisms such as SELinux, Seccomp, ASLR, and CFI.
• Understanding of dynamic analysis with gdb/gdbserver and similar tools
• Basic understanding of compiler tool chains
• Understanding of emulation using Qemu or Unicorn for running code in a non-native environment
• Experience identifying 0-days and vulnerabilities
• Develop high quality and reliable code (C, Assembly, Python, and/or JavaScript)
