Job Description

Position Summary

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 leveraging discovered vulnerabilities
• Communicate security research findings internally and, when and where appropriate, externally Mentor fellow security researchers

Minimum Qualifications

• Must be able to obtain and maintain a TS/SCI security clearance (note, only US Citizens are eligible for security clearances)
• Bachelor's degree in Computer Engineering, Computer Science, Software Engineering, or a related technical discipline and 11 years of professional experience
• Experience participating in CTFs, hackathons, or other cyber competitions
• Experience with Ghidra, Binary Ninja, IDA or other reverse engineering/disassembler tools
• Experience working in Linux fundamentals (understanding sockets, file descriptors, networking, iptables, file systems, kernel, etc.)
• Ability to read and write C and assembly languages as needed ( ARM, MIPS, x86_64)
• 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
• Proven track record of exploit creation targeting Android operating systems and Chrome web browsers

Preferred Experience

• Currently possess a Top Secret security clearance
• 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
• Strong understanding of dynamic analysis with gdb/gdbserver and similar tools
• Basic understanding of processor tool chains and the Android NDK
• Understanding of emulation using Qemu or Unicorn for running code in a non-native environment
• Experience identifying 0-days and vulnerabilities
