Your Impact As a Software Quality Engineer, you will independently own assigned test areas and validate complex, end-to-end customer workflows across physical, virtual, and cloud environments. You will combine hands-on system testing, automation, network-security expertise, and disciplined defect investigation to identify integration and regression risks before release. You will work closely with software development, platform, automation, product, and release teams throughout the development lifecycle. This role requires strong technical judgment, execution ownership, and clear communication of product-quality risks. In this role, you will: * Develop and execute risk-based test plans for Cisco Secure Firewall products and their management, data-plane, platform, and ecosystem integrations. * Validate end-to-end workflows across firewall management, threat inspection, routing, switching, NAT, VPN, identity, logging, policy deployment, and related security capabilities. * Test complex deployment topologies, including standalone, high-availability, clustered, multi-instance, virtualized, and cloud-based environments. * Perform feature integration, system, regression, upgrade, rollback, backward-compatibility, resiliency, recovery, scale, stress, and longevity testing. * Design, implement, maintain, and troubleshoot automated tests using Python-based frameworks and supporting tools. * Build, configure, and maintain representative test environments containing network devices, security appliances, traffic generators, virtual machines, and cloud resources. * Reproduce, isolate, and characterize complex software and system failures using packet captures, logs, traces, core files, system metrics, and diagnostic tools. * Document defects with clear reproduction procedures, technical evidence, business impact, and severity justification. * Participate in feature handoffs, technical reviews, test-plan reviews, defect triage, and cross-functional quality reviews. * Use AI-assisted engineering and testing tools where appropriate to accelerate test design, failure analysis, and automation development while validating outputs and protecting confidential information. ## Related Videos - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [WeAreDevelopers LIVE - Node and Package Security](https://www.wearedevelopers.com/videos/2138-wearedevelopers-live-node-and-package-security) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [The Time Paradox: Building Timezone-Safe Python/Django Applications](https://www.wearedevelopers.com/videos/1915-the-time-paradox-building-timezone-safe-python-django-applications) - [Enabling automated 1-click customer deployments with built-in quality and security](https://www.wearedevelopers.com/videos/83-enabling-automated-1-click-customer-deployments-with-built-in-quality-and-security) ## Related Articles - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
