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 In the Layer-7 Security Software team, we are responsible for at least one, often two to three headline features in every PANOS release. Our code reaches many product lines in the company, and is the critical part of delivering the highest revenue licenses the company offers. Our core Application Identification and Content Inspection Engine runs on Hardware, Virtualized, Container and Cloud-delivered firewalls. Any features that require the inspection or extraction of layer-7 network payload depend on our engine. We are also developing the latest Cloud-delivered Layer-7 security infrastructure. We design and develop key innovative security features such as the industry first Machine Learning powered NGFW, Credential Phishing prevention, URL‑filtering, Cloud‑delivered Data Leak Protection (DLP), and many more exciting features.
Are you looking to tackle a variety of challenging problems across the network, firewall, and Cloud platforms with a team of collaborative and experienced software engineers? Do you want to expand into and innovate on the latest security platforms and delivery technologies? Join us to help build products that do not exist today and solve real‑world problems. Collaboration and clear communication across multi‑functional teams is essential.
