Job Summary
Your Career
We are seeking an AI-savvy Principal QA Test Engineer to transform how we test and validate Prisma Access Add-on Services (Remote Browser Isolation, Application Acceleration, Application Security, and Privileged Remote Access). As a technical leader, you will design and implement autonomous QA workflows that leverage AI to achieve unprecedented test coverage, efficiency, and defect detection. You will take ownership of quality outcomes, mentor teams, and drive innovation in how we approach testing at scale.
YOUR IMPACT
AI-Driven Testing & Autonomous Workflows
Design and implement autonomous QA workflows using AI agents and LLM-based testing frameworks to achieve continuous, intelligent test execution
Build AI-powered test generation systems that automatically create comprehensive test suites from requirements, specifications, and production telemetry
Develop intelligent test oracles using LLMs to validate complex system behaviors, API responses, and user experiences beyond traditional assertions
Create AI-assisted defect prediction and prevention systems that proactively identify reliability and security risks before they reach production
Implement agentic testing workflows that autonomously explore application state spaces, identify edge cases, and generate regression tests
Quality Engineering & Measurable Outcomes
Own and drive key quality metrics: Defect Containment Effectiveness (DCE >95%), Customer Found Regression (CFR 30%)
Lead root cause analysis (RCA) for production incidents and customer-found defects, implementing durable fixes that reduce MTTR and defect escape rates
Drive systematic quality improvements through data-driven insights, reducing vulnerability remediation time and production incident frequency
Participate in system design to ensure quality, observability, and testability are built-in throughout the Prisma Access feature development lifecycle
Test Infrastructure & Platform Development
Develop and enhance AI-augmented test infrastructure that enables scalable, flexible, and @context-aware testing reflecting real-world deployment scenarios
Build RAG (Retrieval-Augmented Generation) pipelines for test knowledge bases, enabling intelligent test selection and prioritization
Design shared testing platforms and patterns for multi-dimensional testing: functional, scale, performance, resiliency, security, and chaos engineering
Integrate AI models and prompts into CI/CD pipelines for continuous quality assessment and intelligent test orchestration
Technical Leadership & Collaboration
Provide technical leadership in browser security, cloud orchestration, distributed systems, and AI-assisted quality engineering
Mentor and upskill team members on AI/ML testing techniques, prompt engineering for test automation, and modern quality practices
Collaborate with Development, SRE, Product Management, and Technical Marketing to align quality strategy with business outcomes
Lead design discussions and articulate technical trade-offs clearly to cross-functional stakeholders
Continuous Learning & Innovation
Stay current with AI/ML advancements and translate them into practical testing innovations (e.g., agentic workflows, multimodal testing, AI-powered observability)
Experiment with emerging AI testing tools and frameworks; share findings and drive team adoption of proven practices
Leverage customer deployment data and telemetry to enhance test strategies and improve CFD efficacy
Qualifications
Your Experience
10+ years of experience in QA/Test Automation Engineering with demonstrated impact on product quality and team practices
3+ years of hands-on experience with AI/ML technologies, including LLMs, prompt engineering, and AI-assisted development workflows
Proven track record of building autonomous testing systems or AI-powered quality engineering tools
Deep expertise in cybersecurity, cloud networking, or distributed systems testing
Strong proficiency in Python and/or Go for test automation and AI workflow development
Experience with LLM frameworks (LangChain, LlamaIndex, AutoGen) and AI model integration
Expertise in REST API testing, web UI automation (Selenium, Playwright, Puppeteer), and cloud-native application testing
Technical Skills
Hands-on experience with AI-powered test generation, intelligent test selection, and autonomous test execution
Experience building RAG pipelines, vector databases, and knowledge graphs for test intelligence
Strong understanding of prompt engineering, few-shot learning, and fine-tuning for testing use cases
Proficiency with observability platforms (Prometheus, Grafana, Splunk) and log analysis using AI
Experience with cloud providers (AWS, Azure, GCP) and infrastructure-as-code (Terraform, CloudFormation)
Knowledge of microservices architecture, distributed systems testing, and performance optimization
Experience with test management systems (TestRail) and defect tracking (JIRA)
Preferred Experience
Experience with browser security solutions: enterprise browsers, remote browser isolation, browser extensions
Background in building AI agents for software testing or autonomous DevOps workflows
Experience with multi-agent systems and orchestration frameworks
Knowledge of security testing, penetration testing, or vulnerability assessment automation
Contributions to open-source testing frameworks or AI/ML testing tools
Experience measuring and improving quality metrics (DCE, CFR, ADDR, MTTR, defect escape rate)
Education
M.S./B.S. degree in Computer Science, Electrical Engineering, or equivalent military experience required
EXPECTATIONS AT PRINCIPAL LEVEL
Scope & Complexity
Given ambiguous goals ("reduce customer-found defects," "improve test coverage"), you independently define the problem, build comprehensive plans, and deliver measurable outcomes
Own service-level quality outcomes across multiple Prisma Access add-on services
Lead multi-team quality initiatives and manage dependencies across Engineering, Product, and SRE
Technical Depth
Anticipate subtle failures in complex, AI-assisted systems; proactively audit for security gaps and reliability risks
Design test architectures that span multiple services and define API testing contracts
Integrate AI @context pipelines into testing workflows; tune models and prompts for accuracy and latency
Leadership & Influence
Mentor junior and mid-level engineers on AI testing practices and quality engineering
Lead adoption of new testing practices (e.g., agentic workflows, AI-assisted RCA) and measure impact
Collaborate effectively across teams and influence peers without authority to align on quality standards
Time Horizon & Impact
Focus extends beyond immediate execution to the operational roadmap and lifecycle of testing services
Drive improvements that compound over multiple release cycles, measurably improving quality metrics quarter over quarter
