Senior Attack Engineer, Offensive Tooling
About The Position
We are looking for an Offensive Tooling Engineer to design, develop, and maintain a custom implant framework and supporting C2 infrastructure. You will build cross-platform post-exploitation capabilities in Rust, develop evasion techniques, and create tooling that operates reliably in defended environments. This is a hands-on engineering role — you will own the full lifecycle from concept through deployment, testing, and monitoring. Your work will have a significant impact on the effectiveness of the NodeZero proactive security platform towards helping defenders prepare themselves against real world threats.
Requirements
- Strong proficiency in Rust, including unsafe code, FFI, async runtimes (tokio), and cross-compilation
- Deep knowledge of Windows internals: Win32 API, process injection, memory manipulation, DLL loading, PE format
- Experience with credential access techniques (DPAPI, LSASS, browser credential stores)
- Familiarity with Linux internals: libc, process enumeration
- Understanding of networking at the packet level (TCP/IP, ICMP, custom binary protocols)
- Demonstrated experience building or maintaining C2 / implant software (custom or open-source)
- Background in red team operations or offensive tool development
- Proficiency in Python for developing and maintaining attack automation and integration
- Experience developing production safe, high quality code deployed to end user machines
Nice To Haves
- Experience with privilege escalation technique development
- Experience researching and implementing EDR evasion techniques
- PE parsing and reflective loading
- Integration testing offensive tools against defended environments
Responsibilities
- Develop and maintain a multi-platform implant written in Rust (Windows, Linux, macOS; x86/x64/ARM)
- Build and extend C2 server infrastructure, task dispatch, and communications protocols
- Implement post-exploitation modules: credential access, process injection, privilege escalation, lateral movement
- Research and implement AV/EDR evasion techniques to keep tooling operational against modern defenses
- Design and build network pivoting and tunneling capabilities
- Write integration tests that exercise tooling against real targets across multiple OS and architecture combinations
Benefits
- Inclusive Team: We value diversity and promote an inclusive culture where everyone can thrive.
- Growth Opportunities: Be part of a dynamic and growing team with numerous career development opportunities.
- Innovative Culture: Work in a collaborative environment that encourages creativity and out-of-the-box thinking.
