Senior Principal Security Researcher

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 Secret or above clearance
Should have a Bachelors degree in Computer Engineering, Computer Science, Software Engineering, or a related technical discipline. Note: This degree requirement is met with four years of professional hands-on experience in a VR, software engineer, or similar full-time position
2 or more years 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, writing shellcode, and return-oriented programming / jump-oriented programming

  Preferred Experience

OS and kernel instrumentation and reverse-engineering
Understanding of fuzzers such as AFL++ or libfuzzer
Understanding of common exploit mitigation mechanisms such as SELinux, Seccomp, ASLR, and CFI.
Comfortable with performing dynamic analysis using gdb/gdbserver and/or similar tools
Understanding of compiler toolchains and their application
Understanding of emulation using Qemu or Unicorn for running code in a non-native environment
Experience identifying/productizing 0days and software vulnerabilities
Passionate on developing high-quality, reliable code (C, Assembly, Python, and/or JavaScript)
