Vulnerability Researcher

Zetier seeks senior Vulnerability Researchers to analyze and counter malicious software and develop operationally critical cyber capabilities. Candidates will demonstrate practical experience designing, developing, and deploying tools intersecting command and control, persistence, and networking.

Required:

• Highly experienced (4+ years) reverse engineering compiled programs (e.g. C/C++)
• Fluent reading common assembly languages (e.g. x86, x86-64, ARM)
• Experienced developing in scripting languages (e.g. Python, Javascript)
• Familiarity with debuggers and decompilers (e.g. gdb, Binja, IDA Pro)
• Ability to obtain and maintain a U.S. security clearance
• Compliance with EO14042 (COVID19 vaccination)

Desired:

• Experience developing/defeating mitigations (e.g. ASLR, DEP, N^X)
• Developed defeats of common anti-RE techniques (e.g. obfuscation)
• Detailed understanding of embedded platforms (e.g. FPGA, physical memory)
• Securely implemented cryptographic primitives (e.g. AES-GCM, SHA256, ECDSA)
• Familiar with program analysis tools and techniques (e.g. control flow, program slicing, taint tracing)
• Effective use of automated analysis (e.g. fuzzers, emulation, sandbox)
• Deep knowledge of file systems and formats (e.g. ELF, PE, Mach-O)
• Effective communication with customers and teammates
• Experience developing proof-of-concept exploits
• Active U.S. security clearance
