Job description

• REDLattice is seeking an iOS CNO Software Engineer to support the development of advanced cyber capabilities for mission-critical national security programs. The ideal candidate will have experience developing iOS software, conducting vulnerability research, reverse engineering native binaries, and building custom capabilities in support of offensive cyber operations.
• In this role, you'll work as part of a highly collaborative engineering team tackling complex technical challenges across iOS platform internals, vulnerability research, exploit development, and reverse engineering. Engineers at REDLattice have the opportunity to make a direct impact, take ownership of challenging technical work, and collaborate with some of the industry's most respected cyber professionals developing next-generation mission capabilities.

Responsibilities

• Design, develop, and deploy custom CNO capabilities for the iOS platform.
• Develop, test, and debug in Objective-C, Swift, C, C++, and Python environments.
• Conduct exploit development, vulnerability research, and proof-of-concept creation.
• Debug user-space and kernel components using LLDB and other native debugging tools.
• Reverse engineer native binaries, iOS frameworks, and operating system components.
• Work with iOS internals, kernel subsystems, security mechanisms, and runtime protections.
• Perform application research and behavioral analysis.
• Trace execution with native debugging and instrumentation tools to isolate and resolve issues.
• Produce documentation for operational use and sustainment.
• Mentor junior engineers and collaborate with mission operators.

Requirements

• Advanced development in Objective-C, Swift, C, C++, and Python.
• Exploit development and memory corruption techniques.
• Kernel debugging and operating system internals knowledge.
• UNIX/Linux internals and system-level engineering.
• Network socket programming and protocol analysis.
• Reverse engineering tools including IDA Pro, Ghidra, LLDB, Frida, and Hopper (or equivalent).
• Security protections including ASLR, DEP, Pointer Authentication (PAC), code signing, sandboxing, and bypass techniques.
• Experience with Git/Bitbucket.
• Active TS/SCI with Polygraph required.
• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Cybersecurity, or a related technical discipline (or equivalent experience).
• Strong analytical, troubleshooting, and problem-solving skills.
• Excellent written and verbal communication skills.
• Ability to work independently and collaboratively within a highly technical team.
• ARM64 assembly language.
• Frida, objection, or similar instrumentation frameworks.
• Mobile vulnerability research and exploit chaining.
• iOS kernel, XNU, Mach, and Objective-C runtime familiarity.
• Jailbreak development or iOS security research experience.
• Offensive tool development and mission support experience.
• Ability to operate autonomously in a high-tempo environment.
