Job Description: About the Role The Brocade Switch and Networking (BSN) business unit of Broadcom is seeking a highly skilled  Software QA Test Engineer – Brocade Switch & Networking (BSN)  to test, verify, and automate the security validation of Brocade’s storage area network (SAN) based networked solutions. In this role, you will be an integral part of a high-performing test team responsible for verifying Brocade’s Fabric OS (FOS), associated hardware switching platforms, management APIs, and developing robust, automated security and functional test suites with focus on the lifecycle of the product line. The ideal candidate possesses a solid foundation in software and hardware engineering principles, a deep understanding of system quality assurance, and a proven track record of designing, executing, and automating complex test plans. We are looking for a professional who can bridge the gap between QA automation engineering and offensive/defensive cybersecurity, with hands-on experience configuring, troubleshooting, and verifying enterprise network operating systems, AAA infrastructures, and cryptographic boundaries. Primary Responsibilities As a Software QA Test Engineer focused on Security and Test Automation, you will own the end-to-end quality assurance and automation processes for critical FOS security features. Your day-to-day responsibilities will include: Security Test Strategy & Planning:  Translate complex security technical specifications, regulatory standards, and break fix changes into comprehensive automated and manual test plans covering functional, integration, regression, performance, and security testing. Automation Framework Development:  Design, develop, and maintain robust test automation frameworks and scripts (primarily in Python) to automate CLI and API testing, improving testing efficiency, execution speed, and coverage. Hardware & Software Backward Compatibility:  Test security policy persistence, cryptographic boundary alignment, and config persistence during firmware migrations with mixed FOS versions (e.g., FOS v10.x, and v9.x).  Ensure seamless security enforcement on Gen 6 and Gen 7 hardware platforms alongside modern Gen 8 platforms. SNMP:  Design and execute test plans validating SNMP GET, GETNEXT, GETBULK, SET, and TRAP/INFORM operations against device MIBs. Verify custom and standard MIB objects (OIDs) return accurate, correctly typed values consistent with actual device/system state.  Test SNMP trap generation, timing, and content for fault, performance, and configuration-change events. Test SNMPv1/v3 support, including authentication and encryption. Perform interoperability testing with common NMS/monitoring tools to confirm real-world compatibility. Develop and maintain automated python test scripts to Test SNMP behavior across builds and regression cycles.  Identify, document, and track SNMP-related defects (incorrect OID values, missing traps, malformed responses, memory leaks under polling load) through resolution. Authentication & Multi-Factor/Federated Authentication (MFA/FA):  Verifying port-level authentication (DH-CHAP E-Port and F/N-Port, FCAP E-Port) and federated authentication (FA) utilizing OAuth 2.0 / JWT tokens with external Identity Providers (IDPs) such as Azure/Entra ID, including M2M (machine-to-machine) flows. Network & Firewall Policy Validation:  Test firewall policies, verifying INPUT and OUTPUT rulesets, ephemeral port restrictions, and default rate-limiting mechanisms. Secure Shell & Secure File Transfers:  Test SSH/SCP/SFTP basic functionality, client/server options, SSH rekeying, host key management and outbound secure file transfers. Auditing & Event Messaging:  Test secure syslog-ng, client authentication, security RAS logs, CLI history completeness, PII/CDA sanitization (GDPR compliance), and TLS/SSL failure records. Cryptographic & Certificate Management:  Verify classic and quantum-safe cryptographic parameters (such as TLSv1.3 ciphers, HTTPS Key Encapsulation Mechanisms - KEM, and post-quantum algorithms like ML-DSA and ML-KEM), certificate operations, CSR generation, SAN/CN validation, and path/revocation validation. Defect Management & Advisory:  Partner with development teams to identify, document, investigate, and track software defects and security vulnerabilities using industry-standard tools. Advise area leads on the overall quality status of assigned features. Qualifications & Requirements (Must Have) Education:  Bachelor’s Degree in Engineering (Computer Science, Cyber Security, Electrical, or equivalent). Experience:  Minimum of  8 years  of hands-on software testing experience, with a heavy focus on security testing and test automation. Automation Scripting:  High proficiency in  Python  for test automation, with hands-on experience automating APIs and CLI-based tools. QA Methodologies:  Robust understanding of software testing methodologies, including functional, negative, boundary, performance, scale, and longevity/stress/soak testing. Networking & Protocols:  Solid foundational knowledge of enterprise networking, routing, cryptography, and core communication protocols (TCP/IP, SSL/TLS, SSH, HTTPS, SFTP, SCP, and cryptographic handshake mechanics). Operating Systems & Virtualization:  Hands-on experience with the installation, configuration, usage, and troubleshooting of Linux, Windows, VMware environments, AAA infrastructure (LDAP, RSA, RADIUS, TACACS+), Federated IDP infrastructure (SAML, OIDC), PQC infrastructure, and vulnerability/intrusive scanner applications. Storage Systems:  Solid foundational knowledge of SAN/Storage technologies. Professional Skills:  Excellent analytical and problem-solving skills, exceptional written and verbal commu
