• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
• 13+ years of hands-on software application development experience with distributed systems and cloud storage solutions
• Proficiency with Java, Spring frameworks (e.g., Spring Boot, Spring Cloud, Spring Security), and containerization with Docker or Kubernetes
• Deep understanding of cloud platforms such as AWS or GCP and experience with observability tools like DataDog, Grafana, or Prometheus
• Expertise across the full Software Development Life Cycle, including version control with Git, design, deployment, and system optimization

What Will Make You Stand Out (Preferred Qualifications)

• Experience integrating AI/ML model inference, AI security controls, or automated threat intelligence into high-throughput microservices
• Expertise in designing for SLAs, high availability, disaster recovery, and cost optimization
• Background in test-driven development (TDD), Agile workflows, CI/CD pipelines, and relational or NoSQL databases

At Zscaler, we are committed to building a team that reflects the communities we serve and the customers we work with. We foster an inclusive environment that values all backgrounds and perspectives, emphasizing collaboration and belonging. Join us in our mission to make doing business seamless and secure.
