Principal Software Engineer in Test; Automation & AI

Job Summary

We're scaling the Prisma SASE Test team and seeking Test Engineers with an Automation‑First Mindset leveraging AI. We are looking for strong technical leaders who take ownership of their areas and are driven to solve problems at every level, in innovative ways. Collaboration and teamwork are at the foundation of our culture and we need engineers who can communicate and work well with others toward a common goal.

Great opportunity to work on AI assisted automation initiatives.

• Design and implement AI‑powered test generation using LLMs to create test cases from requirements, API specs, and user stories.
• Build intelligent test selection systems that predict which tests to run based on code changes (ML‑based test impact analysis).
• Develop self‑healing test frameworks that use AI to detect and adapt to UI/API changes automatically.
• Create anomaly detection pipelines to identify flaky tests and performance regressions without manual triage.
• Leverage AI agents to automate exploratory testing and generate edge‑case scenarios.

• Develop and execute sophisticated software tests and frameworks to validate Prisma SASE functionality and scale, working closely with Development, Product Management, SRE and Technical Marketing teams.
• Provide thorough technical leadership in the areas of cloud‑based orchestration, cloud‑delivered security, cloud networking and automation design.
• Participate in system design so that quality assurance is considered throughout the entire lifecycle of the Prisma Access feature development.
• Develop and/or enhance automated test infrastructure to enable building scalable & flexible tests that reflect real‑world network deployment scenarios.
• Enhance test strategies, automation & build infrastructure with feedback and analysis from real‑world customer deployments.

• 8+ years of experience.
• Understanding of computer networks and protocols.
• Automation skills – Python (backend), JavaScript, Playwright (frontend).
• Strong Python for backend validations with experience building tools, frameworks and reporting.
• Experience with Playwright or similar browser automation.
• Built and led automation frameworks for a team.
• CI/CD pipeline experience (Jenkins, Git Lab CI, Git Hub Actions).
• Understanding of containers, Kubernetes and orchestration.
• Cloud platforms: AWS, Azure, or GCP.
• Security protocols: SSH, IPsec, TCP/IP, DNS, TLS/SSL.
• Bachelor’s Degree or Master’s Degree in Computer Science/Engineering/Networking or equivalent experience required.

• Experience with LLM APIs (Claude, Gemini) for test generation or code analysis.
• Understanding of prompt engineering for automation workflows.
• Experience building AI agents or agentic workflows.

• U.S. citizenship required: due to the nature of the data accessed and federal contract requirements, candidates must be U.S. citizens. Permanent residents (green card holders) are not eligible for this specific role.

• You won't just maintain tests—you'll redefine how testing works using AI to amplify coverage, eliminate repetitive work, accelerate feedback loops, and surface defects earlier in the development cycle.

The compensation offered for this position will depend on qualifications, experience, and work location. For candidates who receive an offer at the posted level, the starting base salary (for non‑sales roles) or base salary + commission target (for sales roles) is expected to be the annual range listed below.
