## About the Role

This role is for engineers who enjoy solving complex problems where an established solution may not exist. The ideal candidate combines strong C/C++ or Rust systems engineering, exceptional debugging and problem-solving skills, and an investigative mindset-the ability to look beyond documented APIs, understand how systems actually work, and explore new ways to solve difficult technical challenges., * Education Requirement: All degrees must be in Engineering, Computer Science, or a closely related field. Bachelor's degree with a minimum of 8 years of related experience; OR Master's degree with a minimum of 6 years of related experience; OR PhD with a minimum of 3 years of related experience; OR equivalent work experience.

 * 6+ years of software engineering, systems engineering, security research, or related experience.
 * Strong programming expertise in C/C++ and/or Rust, including experience with complex, multithreaded, performance-sensitive production software.
 * Strong experience with reverse engineering, API hooking/instrumentation, protocol analysis, binary analysis, security research, or similar investigative engineering techniques.
 * Exceptional debugging and code-analysis skills, with the ability to investigate complex problems across multiple layers of a system on Windows, macOS, and/or Linux.
 * Good understanding of systems concepts like process architecture, memory management, concurrency, IPC, networking, and asynchronous programming.
 * Ability to quickly understand unfamiliar technologies and large, complex codebases.
 * Demonstrated ability to investigate ambiguous technical problems, challenge assumptions, prototype alternative approaches, and develop solutions where an established implementation path may not exist., * Experience developing or modifying Chromium, including areas such as browser/renderer architecture, Mojo/IPC, networking, sandboxing, profiles, extensions, or platform integration.
 * JavaScript/TypeScript/Python and Chrome extension experience
 * Experience with advanced debugging and analysis tools such as IDA Pro, Ghidra, Frida, Detours, packet analyzers, tracing frameworks, or equivalent technologies.
 * Experience with RDP, SSH, SMB, VNC, VDI, application streaming, remote browser isolation, or other remote-access technologies.
 * Knowledge of TCP/IP, TLS, proxies, tunneling, PKI, Kerberos, NTLM, SPNEGO, SSH authentication, and related security technologies.
 * Experience integrating native operating-system functionality with Chromium or another large cross-platform application.
 * Experience with browser media and graphics technologies such as H.264/H.265, hardware video acceleration, GPU rendering, WebGL, WebGPU, or WebCodecs.
 * Experience with WebAssembly or bringing existing native technologies into browser environments.
 * Understanding of browser security architecture including sandboxing, process/site isolation, permissions, profiles, storage, extensions, and browser trust boundaries.
 * Experience analyzing, modifying, or contributing to large open-source projects.

## Description

You will work across Chromium, operating systems, networking, security, and remote-access technologies, rapidly learning unfamiliar systems and turning research and prototypes into secure, production-quality capabilities., * Lead the change - Own critical features from conception to deployment, shaping the core of our Chromium-based Prisma Browser

 * Problem Solving: Leveraging creative approaches to overcome tough obstacles.
 * Collaborate with cross-functional teams to design, build, and optimize features.
