Responsibilities include C/C++ kernel and userland development, Python server and binary-stream processing, firmware extraction, black-box analysis, debugging with GDB and JTAG, fuzzing, test automation, and applying AI/ML to reverse-engineering workflows. The role supports intelligence, defense, and justice customers and requires a current Top Secret clearance.

Lead development of computer network exploitation tools and capabilities for government and critical infrastructure missions. Research operational concepts, support exploitation of commercial networks and computer systems, analyze shell scripts, binaries, and source code, and document technical work. Collaborate with end-users to define requirements and manage the full CNE software development lifecycle. The role requires strong CLI, scripting, collaboration, and network analysis skills.

Lead and build an organic targeting and collection capability for offensive cyber and red-team missions. Perform end-to-end target development, managed-attribution persona creation, deep/dark web collection, credential and blockchain analysis, and deliver finished intelligence. Design AI/LLM automation, build collection tooling and cloud infrastructure, mentor analysts, and author SOPs while ensuring OPSEC and compliance.

The Senior Data Scientist will develop data pipelines for AI applications, optimize data structures, manage databases, and ensure data quality and security.

Develop and integrate advanced Cyber Network Operations (CNO) tools, provide embedded operational support, rapid prototyping, vulnerability research, and software development (design, test, debug). Document findings, present results, manage risks and priorities, and support mission execution in fast-paced government cyber environments.

As a Mobile Application Reverse Engineer at SIXGEN, you will perform static and dynamic analysis of Android and iOS apps, utilize reverse engineering tools, analyze network packets, and contribute to security assessments, while mentoring junior engineers.

Lead end-to-end systems engineering for cyber capability development, producing architecture and design documentation, guiding implementation, coordinating with government stakeholders, and delivering technical briefings and integration/test plans to ensure secure mission outcomes.

As a Software Engineer, you'll design, develop, and deploy software applications for government missions, collaborating with teams to ensure security and performance standards are met.

Perform deep static and dynamic malware analysis, reverse engineering, and media exploitation across Windows and UNIX/Linux; produce technical intelligence, IOCs, and reports; support incident response, DCO/OCO, and USCYBERCOM operational teams; improve enterprise malware analysis platforms and detection capabilities.

Provide systems administration and support for classified federal environments: design, deploy, and maintain Linux and Windows servers, virtualization (ProxMox, Docker), PKI/PGP, networking (VLAN/VPN/iptables/SSH), endpoint OS support (Windows, macOS), scripting/automation (bash, Python, PowerShell), hardware/software diagnostics, and after-hours emergency response. Must hold Top Secret clearance and collaborate across engineering and administrative teams.
