IQ Clarity
Description
As a Network Security Software Engineer, you will help support and advance a next-generation, high-throughput protocol-decoding engine capable of performing deep packet inspection at speeds exceeding 100 Gbps. This engine is central to Intrusion’s Shield security platform, and your contributions will play a direct role in safeguarding enterprise networks, data centers, and cloud systems in real time. You’ll work with cutting-edge AI-driven threat detection to stop attacks as they emerge.
Responsibilities
Design, code, and deliver new features for a Linux-based network security appliance within an agile workflow.
Improve and fine-tune high-performance C/C++ components leveraging XDP and eBPF to handle packets at line-rate throughput.
Build and maintain protocol decoders for both standard networking protocols and OT (operational technology) environments.
Partner with cybersecurity researchers and AI specialists to uncover malicious patterns and surface anomalous behavior.
Diagnose and resolve complex software defects, such as memory leaks, race conditions, and system crashes.
Develop unit tests to ensure functionality, stability, and long-term maintainability.
Package software via Linux RPMs and manage code releases using git within automated pipelines.
Produce clear design documentation (low-level and high-level) and present or justify architectural decisions.
Take part in daily stand-ups and contribute to planning during program increments.
Required Qualifications
Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent professional experience.
Strong hands‑on background in C/C++, algorithms, and data structures.
Solid understanding of key network protocols (TCP/IP, DNS, HTTP, TLS).
Proficiency developing in Linux environments.
Experience building applications that interact with SQL databases.
Preferred / Nice to Have
Prior experience creating network‑centric applications (e.g., web services, socket‑based systems).
Familiarity with containerization and virtualization technologies.
Background working with high‑availability systems.
Experience writing Linux kernel modules or device drivers.
Understanding of kernel‑level memory management and NUMA architectures.
Exposure to Python, CGI, and git.
Foundational knowledge of networking and security principles.
