It plays a key role in orchestrating and executing the capabilities required to identify vulnerabilities across diverse enterprise environments and technologies.\nGiven its central role in vulnerability detection, the Module Loader requires a high degree of accuracy, reliability, scalability, performance, and backward compatibility. The team works on complex engineering challenges involving vulnerability detection, networking, protocols, operating systems, security technologies, and large-scale enterprise environments.\nBe part of the team building and validating one of the foundational components powering Qualys vulnerability detection.\nCore Responsibility\nAs a Senior Software QA Engineer, you will be responsible for ensuring the quality, reliability, performance, and scalability of the Module Loader and its remote vulnerability detection capabilities.\nThis is a hands-on technical QA/SDET role where you will own quality from requirements and design through release and production. You will work closely with developers, security researchers, Product Management, and other engineering teams to understand vulnerability detection requirements and translate them into comprehensive test strategies.\nYou will be expected to go beyond functional validation and understand how vulnerability detection works, identify potential gaps and edge cases, create complex test environments, automate validation, analyze failures, and troubleshoot problems across application, operating system, network, and protocol layers.\nYou will have end-to-end quality ownership of features, including test design, automation, functional and integration testing, performance and scalability testing, regression qualification, debugging, and production issue analysis.\nPosition Requirements\nEligible candidates should meet the following criteria.\nRequired\n4+ years of hands-on experience in Software QA, SDET, or Software Testing for complex enterprise software products.\nStrong experience in testing system-level, security, networking, or distributed applications, preferably on Linux/Unix platforms.\nStrong hands-on experience with test automation using Python, Shell scripting, C/C++, or equivalent programming/scripting languages.\nAbility to independently understand complex feature requirements and technical designs and develop comprehensive test strategies, test plans, test scenarios, and automation.\nStrong understanding of Linux/Unix operating systems, processes, services, file systems, permissions, package management, and system-level troubleshooting.\nStrong knowledge of networking fundamentals and protocols, including TCP/IP, DNS, HTTP/HTTPS, SSL/TLS, proxies, and client-server communication.\nStrong debugging and problem-solving skills with the ability to investigate failures across application, operating system, and network layers.\nExperience analyzing logs, network traffic, system behavior, application failures, CPU/memory utilization, and other diagnostic information to drive issues toward root cause.\nExperience in functional, integration, regression, negative, compatibility, upgrade, and end-to-end testing.\nAbility to identify corner cases, failure scenarios, environmental dependencies, and regression risks beyond documented requirements.\nExperience validating software across heterogeneous enterprise environments involving different operating systems, services, network configurations, and software versions.\nExperience with performance, scalability, reliability, and resiliency testing of enterprise products.\nStrong focus on an automation-first approach, with experience building maintainable and reusable automated tests and reducing repetitive manual validation.\nExperience integrating automation into CI/CD pipelines and analyzing failures to differentiate product defects, automation failures, and environmental issues.\nStrong understanding of SDLC/STLC, defect lifecycle, risk-based testing, release qualification, source control, and software engineering best practices.\nAbility to work independently with developers and other engineering teams to reproduce, debug, and drive complex product issues to closure.\nStrong analytical mindset with the ability to question assumptions and identify scenarios where expected vulnerability detection behavior may produce incorrect, incomplete, inconsistent, or unexpected results.\nSelf-driven and quick learner with an interest in understanding new technologies, operating systems, protocols, applications, and security concepts.\nExcellent communication and collaboration skills with the ability to engage with different technical teams, seek clarification, challenge assumptions constructively, and build consensus.\nDesirable Requirements\nExperience in the Cyber Security, Vulnerability Management, Vulnerability Assessment, or Network Security domain.\nUnderstanding of vulnerability detection concepts and security assessment methodologies.\nExperience testing network scanners, vulnerability scanners, security products, or other network-intensive system software.\nGood knowledge of common enterprise protocols and services.\nKnowledge of SSL/TLS, certificates, authentication mechanisms, and cryptography fundamentals.\nExperience with packet analysis and network troubleshooting tools such as Wireshark/tcpdump or equivalent tools.\nExposure to C/C++ applications and debugging tools such as GDB.\nExperience creating and maintaining complex test environments consisting of multiple operating systems, applications, services, and network configurations.\nExposure to containers, virtualization, and cloud infrastructure.\nExperience developing or enhancing QA automation frameworks, test infrastructure, or large-scale test environments.\nBasic Qualifications\nBachelor's / Master's degree in Computer Science, Computer Engineering, Information Technology, or a related technical discipline (M.E / M.Tech, B.E / B.Tech, MCA) and 4 to 6 years of relevant experience as a Senior Software QA Engineer, Software QA Engineer, SDET, Automation Engineer, Software Test Engineer, or a similar technical quality engineering role.","description_format":"text","description_chars":6547,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud
