Role Overview:

We are seeking highly skilled C/C++ engineers to work with system-level libraries and tools such as OpenSSL, FFmpeg, glibc, libssh2, zlib, systemd, tcpdump and support infrastructure for AI-driven software engineering systems. In addition, you will play a key role in building the backend stack for model training and evaluation pipelines that support intelligent systems like the SWE Bench, where AI agents assist in real-world software maintenance and patching workflows

Responsibilities:

• Develop, maintain, and extend high-performance, secure system software in C/C++.
• Integrate and work with open-source projects such as OpenSSL, FFmpeg, glibc, systemd, tcpdump, libssh2, ImageMagick, and FreeRDP.
• Design tools and infrastructure to support model training and evaluation workflows.
• Build systems for suggesting code patches based on bug reports, issue descriptions, and vulnerability IDs.
• Automate assessment of PRs and patch diffs for correctness and completeness.
• Develop solution plans, set up reproducible environments, and evaluate test outcomes.
• Collaborate with AI engineers on integrations involving Rust bindings and Python-based orchestration tools.
• Analyze low-level system behavior using profiling, tracing, and debugging tools.
• Write clear, maintainable code and documentation for internal systems and external libraries.

Required Qualifications:

• Expert-level experience in C and/or C++ (C99+, C++11/14/17).
• Strong understanding of systems programming, memory management, and networking internals.
• Hands-on experience with Linux kernel, glibc, and multithreaded programming.
• Familiarity with libraries such as OpenSSL, zlib, FFmpeg, libssh2, and ImageMagick.
• Proficiency with debugging and diagnostics tools like gdb, valgrind, perf, and tcpdump.
• Experience integrating or extending open-source libraries and toolchains.
• Comfortable with build systems such as make, cmake, and autotools.
• Experience with Python, bash scripting, and Docker.
• Exposure to DevOps practices.

Good to have:

• Experience with model evaluation workflows involving static and dynamic code analysis.
• Understanding of AI-assisted code generation tools and feedback loops.
• Background in building tools for test orchestration, sandboxing, and runtime validation.
