- Strong socket programming and packet-level understanding of IP, TCP, and application-layer protocols
- Proficiency tracing execution with debuggers/tools such as WinDbg, gdb, IDA Pro
- Experience reverse engineering native binaries
- Experience developing proof-of-concept exploit software

- file system internals (e.g., NTFS, ext2, btrfs)
- access control mechanisms (MAC/DAC)
- process/thread APIs, data structures
- Understanding of modern mitigations (ASLR, DEP, NX), approaches to bypass them, and methods to detect bypass attempts
- Experience with version control (e.g., git, GitLab)
- Native-level mobile development experience (Android native/NDK or similar)
- Vulnerability analysis experience
- Assembly familiarity, preferably ARM
