## Description

Please note this posting is to advertise potential job opportunities. This exact role may not be open today but could open in the near future. When you apply, a Cisco representative may contact you directly if a relevant position opens. Applications are accepted until further notice. Meet the Team Network Engineering builds the foundational software and hardware systems that connect the world. Within our Core Platform Software and Toolchains organization, our team develops, optimizes, and maintains the mission-critical compiler, debugger, and code analysis toolchains that power Cisco IOS-XE, Silicon One, and cloud-scale routing platforms. We operate at the leading edge of systems engineering—bridging modern processor architectures with LLVM/GCC optimizations, custom IR transformations, and high-fidelity runtime debugging infrastructure. As active contributors to the open source toolchain ecosystem, we solve complex low-level engineering challenges to maximize code generation efficiency, developer velocity, and binary resilience across Cisco's global product portfolio. Your Impact As a Compiler Software Engineer II, you will architect, implement, and optimize advanced compilation, code analysis, and debugging toolchains that power Cisco's core networking platforms. You will develop sophisticated compiler transformations and runtime diagnostic tools in modern C/C++, optimize LLVM/GCC backends and intermediate representations (IR) for ARM64 and x86 architectures, and enhance GDB/LLDB debugging capabilities. You will build robust automated validation pipelines using Python and CI/CD frameworks, advance DWARF debug format standards, and integrate AI-assisted developer productivity tooling into modern engineering workflows. Success in this role means driving end-to-end toolchain excellence, delivering high-performance code generation improvements, and contributing impactful enhancements to open-source systems. Minimum Qualifications Meet one of the following (completed within the past 3 years or expected to be completed within the next 12 months): -A Bachelor's degree with 0 years of work experience; OR -An educational or workforce development program (e.g., Associate's, Apprenticeship, Boot camp, or Certification) with 1 year of work experience; OR -A High school diploma (or equivalent) with 2 years of work experience. Qualifying education and work experience should be in Computer Engineering, Software Engineering, Computer Science, Information Technology, or a related field. Demonstrated programming proficiency in C or C++ with a strong foundational understanding of memory management, pointer arithmetic, and data structures. Foundational understanding of computer architecture (ARM or x86), operating system fundamentals (processes, memory management), and the ability to read assembly language. Coursework, academic research, or hands-on project experience in compiler construction, code generation, LLVM infrastructure, or debugger fundamentals (GDB, LLDB, DWARF). Preferred Qualifications Hands-on experience with LLVM, Clang, GCC, or GDB open-source toolchains, including writing custom LLVM passes or toolchain extensions. Familiarity with DWARF debug format specifications, object file structures (ELF), symbol tables, and binary analysis utilities (GNU Binutils). Practical experience developing test automation scripts using Python and Linux shell utilities in a CI/CD environment. Experience configuring or cross-compiling toolchains for Embedded Linux or networking operating systems (routers/switches). Interest or experience integrating AI-assisted developer tools or modern IDE plugins (VSCode, Language Server Protocol / DAP) to enhance software development workflows. Why Cisco? At Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era – and beyond. We’ve been innovating fearlessly for 40 years to create solutions that power how humans and technology work together across the physical
