Job Description – C++ Systems Software Engineer Engagement Type: Short-Term Contract (3 Months) Start Date: Immediate Work Commitment: 8 Hours/Day with mandatory 4-hour overlap with PST Availability Requirement: Candidates must be fully available for this engagement and should not be working another full-time role simultaneously. About the Role We are seeking highly skilled C/C++ Systems Software Engineers to work on advanced system-level infrastructure and tooling that powers AI-driven software engineering systems. In this role, you will work extensively with low-level system libraries, networking tools, debugging frameworks, and open-source infrastructure projects such as OpenSSL, FFmpeg, glibc, systemd, libssh2, tcpdump, zlib, and ImageMagick.
You will also contribute to backend infrastructure supporting AI model training and evaluation workflows, including intelligent systems similar to SWE Bench, where AI agents assist with software maintenance, bug fixing, patch validation, and automated code repair workflows. This role is ideal for engineers with strong systems programming expertise, deep Linux internals knowledge, and hands-on experience working close to operating system and networking layers. Key Responsibilities Develop, maintain, and optimize high-performance system software in C/C++.
Work with and extend open-source libraries and infrastructure components including: OpenSSL FFmpeg glibc systemd tcpdump libssh2 zlib ImageMagick FreeRDP Build infrastructure and tooling to support AI model training and evaluation workflows. Develop systems capable of generating and validating code patches based on: Bug reports Issue descriptions Vulnerability IDs PR diffs Design reproducible environments for software testing and runtime validation. Automate assessment and validation of pull requests and generated patches.
Analyze low-level system behavior using profiling, tracing, and debugging tools. Collaborate with AI engineers on integrations involving: Rust bindings Python orchestration frameworks AI-assisted engineering systems Write clean, maintainable, and well-documented production-grade code. Participate in technical discussions, debugging sessions, and architecture improvements.
Required Skills & Qualifications Mandatory Requirements Expert-level 4+ years of experience in: C (C99+) C++ (C++11/14/17) Strong understanding of: Systems programming Memory management Networking internals Multithreaded programming Hands-on experience with: Linux kernel internals glibc POSIX systems Experience working with libraries/tools such as: OpenSSL zlib FFmpeg libssh2 ImageMagick systemd tcpdump Proficiency with debugging and diagnostics tools: gdb valgrind perf tcpdump Experience integrating and extending open-source libraries and toolchains. Comfortable working with build systems including: make cmake autotools Experience with: Python scripting Bash scripting Docker Exposure to DevOps practices and deployment workflows. Good to Have Experience with AI-assisted software engineering systems.
Familiarity with static and dynamic code analysis workflows. Understanding of model evaluation pipelines and automated testing systems. Experience building: Test orchestration tools Sandboxing systems Runtime validation frameworks Exposure to Rust integrations or bindings.
Knowledge of SWE Bench-style evaluation environments. Interview & Evaluation Process Selection Process Profile Review 2 Rounds of Technical Delivery Interviews 30 Minutes Each Additional Requirements Candidates must be immediately available or able to join on short notice. LinkedIn profile is mandatory and must be included in the resume submission.
Strong communication and collaboration skills are expected. Candidates should be comfortable working in fast-paced engineering environments with high technical ownership.
