About The Position

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.

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.

Nice To Haves

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+.

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).
