Job description

Our client is seeking an elite engineer with extensive experience working with low level structures and interfaces within Windows. You’ll have the opportunity to build the future of technology stacks, working in a small team with the ability to substantially influence technical direction and operate without micromanagement.

The role will be focused on solving currently unsolved challenges in the security industry. Familiarity working in undocumented or semi-documented areas of the operating system will be crucial, requiring a “hacker” mentality to tackle problems creatively. Driver development expertise is recommended and familiarity working with malware is highly beneficial.

  • Desire to work in a dynamic field, facing and solving problems which regularly have no currently known solution within the industry
  • Proficiency in C and C++ on Windows
  • Minifilter driver development
  • Experience working with system instrumentation via callbacks, hooks, or hypervisors
  • Extensive knowledge of the Windows API, particularly the lower level Nt APIs.
  • Familiarity with the underlying structures of the registry and NTFS/FAT file systems
  • Solid background in malware analysis and reverse engineering using IDA, HIEW, OllyDbg, or Windbg
  • Multi-threaded client/server application development experience

All your information will be kept confidential according to EEO guidelines.
