The ideal candidate has deep expertise in Python for application logic, familiarity with lower-level languages like C/C++, and a strong command of networking protocols and operating system internals.

Required Qualifications
-. 3+ years of experience in backend or systems software development, focusing on agent/client-side applications.
-. Expert proficiency in Python (including concurrency and low-level system calls).
-. Strong understanding of operating system fundamentals for both Linux and Windows (e.g., process management, file systems, permissions).
-. In-depth knowledge of TCP/IP and common network protocols, including HTTP(S) and TLS/SSL.
-. Experience in network programming, including packet capture analysis (PCAP) or socket programming.
-. Familiarity with host-based security controls, firewall configuration (iptables), and network segmentation.
-. Proficiency with Git and agile development methodologies.

Preferred Qualifications
-. Experience developing with network proxies (forward/reverse) or tunneling technologies.
-. Prior experience in security (Endpoint Detection and Response – EDR, anti-virus, monitoring) or IT Operations Management (ITOM) domains.
-. Familiarity with cloud platforms (AWS, Azure, or GCP) for connecting agent data to backend services.

Job responsibilities

Agent Development & Systems Programming
-. Design, develop, and test high-performance, low-footprint software agents/actors using Python.
-. Ensure the agent software is stable, reliable, and secure across multiple operating systems, specifically Windows and Linux environments.
-. Develop robust mechanisms for persistence, self-healing, and minimal resource utilization on the endpoint.
-. Implement secure and efficient inter-process communication (IPC) within the agent architecture.

Networking & Protocols
-. Design and implement resilient communication modules that handle diverse network environments (high latency, low bandwidth).
-. Deeply understand and leverage various network protocols, including HTTP(S), SSH, and custom protocols for command and control.
-. Work with raw network data, including parsing and analyzing PCAP data for network monitoring and telemetry.
-. Implement advanced network control mechanisms, such as configuring host-level firewalls (iptables/nftables on Linux or Windows Firewall) and managing proxies.

Operational Excellence
-. Integrate the agent with the central cloud backend (APIs, message queues) and ensure data is transferred reliably and securely.
-. Develop comprehensive unit and integration tests to guarantee high code quality and testability across different OS platforms.
-. Utilize and manage version control with Git (e.g., GitHub, GitLab) and participate in rigorous code reviews.
-. Collaborate with QA and DevOps teams on agent deployment, monitoring, and release pipelines.
