In this role, you will work on complex, systems-level software that underpins networking, security, and operating system functionality. You’ll collaborate closely with other engineers to troubleshoot and enhance large-scale software systems, improve test automation reliability, and ensure high-quality releases across multiple projects.

A typical day includes debugging failures in automated pipelines, enhancing test coverage for networking and security components, analyzing low-level system behavior using traces and debugging tools, and validating fixes through both automated and manual testing. You’ll gain deep, hands-on exposure to the Windows networking stack while working across both Windows and Linux environments.

Responsibilities:

• Design, develop, test, and maintain systems-level software and supporting utilities
• Analyze system and software requirements and translate them into robust technical solutions
• Debug, troubleshoot, and fix complex issues in both new and legacy codebases
• Enhance and stabilize automated test suites to improve coverage and pipeline reliability
• Investigate test failures across multiple projects and drive issues to resolution
• Collect, analyze, and interpret diagnostic data such as logs, instrumentation, and system traces
• Implement enhancements and updates to existing software to meet evolving standards
• Prepare clear and detailed software design, test, and validation documentation
• Perform post-implementation validation and resolve defects identified during testing
• Execute periodic manual testing for networking and security scenarios (e.g., VPN, IPSec, WSL)

Qualifications:

• Bachelor’s degree in Computer Science, Computer Engineering, or a related technical field
• 5–7 years of professional software engineering experience
• Strong foundation in computer science principles, including data structures, algorithms, and software design
• Proven experience designing and developing large-scale systems software
• Hands-on experience writing systems-level code in C and C++
• Experience debugging and maintaining both new and legacy production systems
• Proficiency with debugging and diagnostic tools (e.g., Windows Debugger, gdb, Wireshark, tcpdump)
• Experience collecting and analyzing system traces such as WPP/ETW
• Working knowledge of networking protocols such as IPSec, TCP, and QUIC
• Experience working in both Windows and Linux operating system environments
• Ability to work independently, diagnose complex problems, and drive solutions to completion

Preferred Qualifications:

• Strong experience developing in a Windows OS environment
• Familiarity with VPN technologies, IPSec-based connection security, and software-defined networking
• Experience enhancing and maintaining test automation across networking and security components
• Expertise with PowerShell scripting and YAML-based configurations
• Experience improving test pipeline stability and measuring quality through automated test metrics
• Comfort collaborating in an onsite engineering environment focused on close teamwork and rapid iteration
