The Role: 

We're hiring a QA Engineer to own quality for our SaaS-based Quantum Security Posture Management platform. This role is focused on rigorous, product-level testing - functional correctness, regression coverage, and automation - for a platform that models Layer 2/Layer 3 networks and evaluates security posture. You'll work closely with developers to catch defects early and build confidence in every release.

Responsibilities:

• Design, write, and execute detailed test cases and test plans for platform features: network discovery, topology mapping, policy/rule analysis, posture scoring, alerting, and reporting.
• Perform functional, regression, integration, and API testing across releases and sprints.
• Validate correctness of Layer 2/Layer 3 network modeling (VLANs, routing, ACLs, NAT, firewall rules) as represented and analyzed by the product.
• Build and maintain automated test suites (UI and API level - Selinium, REST Assured, Pytest) to increase regression coverage and reduce manual testing effort.
• Set up and maintain test environments/labs, including virtual network topologies (e.g., GNS3, EVE-NG, containerlab) and multi-vendor device configs (Cisco, Juniper, Palo Alto, Fortinet).
• Log, triage, and track defects; work with engineering to reproduce, root-cause, and verify fixes.
• Participate in sprint planning, story grooming, and release readiness reviews, providing a quality/risk perspective.
• Contribute to test strategy improvements, including shift-left testing practices and CI/CD test integration.
• Maintain clear, thorough test documentation (test cases, coverage matrices, defect reports).

Requirements:

• 10+ years of experience in software QA/testing, ideally for SaaS or enterprise infrastructure products.
• Working knowledge of Layer 2/Layer 3 networking (VLANs, subnetting, routing protocols, ACLs, NAT, firewall logic).
• Foundational security knowledge - firewall policies, segmentation, common vulnerabilities/misconfigurations.
• Experience with manual and automated testing (e.g., Selenium, Playwright, Postman/Newman) and defect tracking tools (Jira, etc.).
• Comfortable testing REST APIs and validating JSON/data payloads.
• Strong attention to detail and ability to write clear, reproducible bug reports.

Preferred Qualifications:

• Scripting experience (Python, Bash) for test automation.
• Experience with virtual network labs (GNS3, EVE-NG) or cloud networking (AWS VPC, Azure VNet).
• Exposure to CI/CD pipelines and test integration.
• Certifications such as ISTQB, CCNA, or Security+.
