  • Knowledge of modern software engineering principles, including version control, testing frameworks, and agile workflows.
  • Experience with high-side development environments and non-attributed network configurations.

  • Experience or interest in offensive cyber operations, vulnerability research, and software reverse engineering.
  • Knowledge of Android application architecture and experience or interest in mobile vulnerability research.
  • Experience with low-level programming in C/C++ and utilizing debuggers such as gdb or similar tools.
Perks and Benefits:
  • 8 weeks paid leave - 4 weeks of personal leave, 3 Yay! days, take off on your birthday,11 paid holidays and optional leave up to 6 days through Belay's volunteer program
  • 10% matching in 401(k) contributions vested on day one
  • $5,000 annual training/tuition
  • Student Loan Repayment Program
  • 100% company-funded HSA
  • Rich medical coverage (100% coinsurance)
  • Dental coverage including orthodontia
  • Up to $420,000 in life insurance, premiums 100% company funded
