Quality Engineering - Professional 3 (DEX & Horizon Interoperability)

Core Responsibilities

Define and drive the automation testing approach for Horizon and DEX interoperability, aligned with product and program needs

Identify areas for automation and prioritise work based on risk, complexity, and business value

Design, build, and maintain automated interoperability, integration, and end-to-end tests across Horizon and DEX, primarily in Python

Plan and execute compatibility testing across current and previously supported product versions

Partner with feature teams from the design phase so new Horizon and DEX work is testable, and automated coverage is in place before it ships into the integrated stack

Build and maintain reusable, scalable test frameworks and shared libraries across supported platforms (Windows, Linux, and other supported clients)

Standardise processes, tools, and frameworks for automated testing, CI/CD, and quality gates

Design, implement, and maintain CI/CD pipelines (GitHub Actions and Jenkins), including pipeline templates, so component, integration, and end-to-end stages are automated, stable, and properly integrated

Implement and refine quality gates and reporting dashboards; track coverage, execution stability, and pipeline health

Implement and maintain scalable test infrastructure (on-premises, virtualised, and cloud) so environments stay stable, accessible, and usable for automated runs

Extend coverage across supported deployment platforms and real-world topologies, including hypervisors and gateway or proxy network paths

Work closely with developers so automation is integrated early and tests catch issues at unit, integration, functional, and UI levels where applicable

Review test suites for consistency, maintainability, and best practices; refactor scripts and optimise execution time as the suite grows

Investigate failures that span Horizon and DEX and drive them to root cause with engineering

Engage cross-functionally on end-to-end and interoperability scenarios to improve automation

Provide documentation and support so developers can understand and, where appropriate, self-manage test environments

Continuously evaluate new tools and technologies to improve automation efficiency and reliability

Leverage AI-assisted tools to accelerate test scaffolding, mock generation, refactoring, and debugging, and apply engineering judgment to review, validate, and harden the output for reliability, security, and maintainability

Qualifications

Required

3 to 8 years of experience in test automation for enterprise and/or cloud-hosted platforms (or equivalent experience).

Strong Python skills for test automation (frameworks such as pytest); additional languages (Java, Go, PowerShell) are useful.

Hands-on experience building and maintaining CI/CD pipelines using GitHub Actions and/or Jenkins (or equivalent: Azure DevOps, GitLab CI).

Experience owning automated tests end to end — not only manual test execution.

Experience with upgrade testing and backward compatibility (mixed-version environments, upgrade paths, agent/client coexistence).

Experience testing cloud deployment and lifecycle scenarios (onboarding, configuration, upgrades), not only API-level functional tests.

Hands-on experience using a major public cloud (Azure preferred) to create and tear down test environments.

Ability to debug issues across multiple layers (on-premises components, cloud service, gateway/edge, network, endpoint) and communicate findings clearly in writing.

Preferred

Experience with Omnissa Horizon Suite of products or similar end user computing products/solutions.

Experience with monitoring solutions or telemetry products.

Familiarity working with Hypervisors and Cloud platforms (vSphere, Azure, AWS or other clouds).

Infrastructure-as-code or environment automation (Terraform, Ansible, or similar).

Experience extending an automation framework across new clouds or topologies rather than rewriting it each time.
