## About the Role

* 3+ years of relevant software development experience.
 * Strong C/C++ skills, with solid grounding in memory management, concurrency, and performance tuning in production code.
 * Deep Windows internals knowledge - Win32/NT API, processes and threads, virtual memory, synchronization, and the I/O subsystem.
 * Hands-on low-level Windows development, such as kernel-mode or user-mode driver work.
 * Comfortable with Windows debugging tools - WinDbg, the Visual Studio debugger, Sysinternals, and similar.
 * Experience writing secure code and tracking down memory corruption, race conditions, and crashes from dump files.
 * Working knowledge of a scripting language such as Python for tool development and automation.
 * Familiarity with reverse engineering tools (e.g., IDA Pro, Ghidra, GDB) in addition to Windows-native debugging tools.
 * Understanding of networking fundamentals (TCP/IP, DNS, HTTP/S) and common network protocols.

Bonus points if you have:

 * Prior experience supporting the Intelligence Community, or other federal CNO/cyber mission programs.
 * Experience with exploit development, binary analysis, or vulnerability research.
 * Familiarity with anti-virus/EDR evasion techniques, obfuscation, and anti-forensics methods.
 * Familiarity with Agile/Scrum development methodologies and modern CI/CD tooling in classified environments.
 * Experience with embedded systems, firmware, or mobile platform development (iOS/Android).
 * Ability to work independently and collaboratively within a small, mission-focused team under tight timelines.

Security clearance:

 * Active TS/SCI security clearance is required.

## Description

Our team is seeking a mid-level Computer Network Operations (CNO) Developer to design, develop, and test sophisticated software capabilities in support of national security missions. The successful candidate will work within a close-knit team of developers, reverse engineers, and vulnerability researchers to build custom tools that operate reliably across diverse network environments. This role requires strong low-level programming skills, a deep understanding of operating system internals, and the judgment to operate within strict legal, ethical, and operational constraints.

This position requires working full-time on site at the Accenture Federal Services facility in Herndon, VA.

The work you'll do:

 * Design, develop, test, and maintain custom software capabilities used in computer network operations.
 * Perform low-level software development in C/C++, Python, and/or Assembly for Windows, Linux, and/or embedded targets.
 * Analyze target systems and network architectures to identify technical requirements and constraints for capability development. Collaborate with vulnerability researchers and reverse engineers to integrate exploits and achieve reliable code execution.
 * Develop and maintain command-and-control (C2) communication protocols.
 * Produce clear technical documentation, including design specifications, test plans, and operational employment guides.
 * Support integration, test, and evaluation events and provide technical support during operational missions.
 * Stay current on emerging operating system security features, offensive cyber technologies, and tradecraft to inform capability design.
 * Adhere strictly to all legal, policy, and oversight requirements governing CNO development and employment.
