Principal Security Researcher - Cloud & AI (Cortex Cloud)

Company Description

Our Mission

At Palo Alto Networks® everything starts and ends with our mission:

Being the cybersecurity partner of choice, protecting our digital way of life.
Our vision is a world where each day is safer and more secure than the one before. We are a company built on the foundation of challenging and disrupting the way things are done, and we’re looking for innovators who are as committed to shaping the future of cybersecurity as we are.

Who We Are

We believe collaboration thrives in person. That’s why most of our teams work from the office full time, with flexibility when it’s needed. This model supports real-time problem-solving, stronger relationships, and the kind of precision that drives great outcomes.

Job Description

Your Career

As a Principal Security Researcher on the Cortex Cloud research team, you’ll lead deep, hands-on security research across cloud and AI environments- from uncovering vulnerabilities and novel attack paths to building the protections that stop them.

Your impact doesn’t end with detections. This team is also responsible for driving product innovation: identifying gaps in how cloud environments are secured, finding new ways to close those gaps, and partnering with engineering, product and marketing to take those ideas from a POC to implementation. Whether it’s a new detection engine, risk signal, or protection method- your research directly shapes the product.

You'll research the AI attack surface in depth, and push the boundaries of what cloud and AI security can achieve. If you're looking for a role where research leads to real-world defense- and product innovation is part of your day job- this is the team.

Your Impact

Research and uncover vulnerabilities and abuse paths in cloud services, with a strong focus on AI, identity, and data pipelines
Collaborate with product and engineering to ship detections and logic based on your findings
Research-driven impact - drive innovation from idea to execution: Identify emerging security gaps, build proof-of-concepts, and partner with engineering, product and marketing to translate research into actual product features and detection logic.
Represent the team through public blogs, conferences and research collaborations with cloud vendorsPublish internal or external research and represent the team at industry events or blogs.
Lead the discovery of novel attack vectors- e.g., cross-tenant access, NHI abuse, RAG poisoning, privilege escalation

Qualifications

Your Experience

Minimum of 6 years in security research, including at least 2 years focused on cloud security
Deep understanding of IAM, network, and data services posture in AWS, Azure, or GCP Research
Strong understanding of the attacker’s mindset and proven experience in applying defensive tactics
Hands-on experience in programming and scripting with C++/Python
Experience with AI / Web/ Cloud/ K8S vulnerability research
Proven ability to conceptualize, plan, and execute research from ideation through POC to full implementation

Nice to have

Hands-on experience detecting or simulating attacks in AI pipelines (e.g., RAG poisoning, prompt injection, model exfiltration)
Public research, blog posts, or conference presentations
Resourcefulness and creativity in problem-solving, achieving high standards in challenging scenarios
Deep understanding of the cybersecurity market, including key players, customer needs, and emerging trends
Excellent communication and teamwork skills, with the ability to lead initiatives and work collaboratively across the organization

Additional Information

The Team

This is one of the most impactful and innovative teams within Cortex Cloud.

We’re a small, senior group of researchers responsible for uncovering vulnerabilities, modeling attacker behavior, and leading product innovation across the posture management platform. Our work has led to multiple vulnerability disclosures in GCP and Azure, and we regularly publish blogs, speak at top conferences, and collaborate with cloud vendors to push the industry forward.

But research is just the beginning. We turn findings into real-world protection- designing detections, building proof-of-concepts, and working closely with product and engineering to bring our ideas to life. The detections we build, the attack paths we model, and the features we invent are used by thousands of customers across Cortex Cloud’s key modules: CIEM, DSPM, AISPM, and KSPM.
