Ready to make an impact at the company pioneering security transformation in the AI era? Join us at Zscaler. Role We are looking for a Sr. Production Engineer to join our team. This is a hybrid (3 days a week in San Jose, CA) or Bellevue, WA role, reporting to the Senior Manager, Site Reliability Engineering in the Cloud Infrastructure & Operations department. Join Zscaler to be a force multiplier for the reliability of a global platform protecting over 15 million users. In this role, you will provide the technical vision and hands-on execution to drive an "automation-first" culture across the company. By maturing our observability and architectural standards, you will directly reduce our Mean Time to Mitigate (MTTM) and shape the scalability of our globally distributed, multi-cloud infrastructure. What you’ll do (Role Expectations) • Design and implement highly available, scalable infrastructure across AWS, Azure, GCP, and bare-metal environments • Drive an "automation-first" culture by writing code (Python/Go) to eliminate manual toil and build self-healing systems • Implement and maintain sophisticated observability (Prometheus, Grafana, OpenTelemetry), define SLIs/SLOs, and establish error budgets • Act as a lead Incident Commander (TDO on-call), develop response playbooks, and conduct deep-dive post-incident analyses • Partner with Engineering and partner teams to conduct operability reviews Who You Are (Success Profile) • You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful. • You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution. • You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact. • You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust. • You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose. What We’re Looking for (Minimum Qualifications) • Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain • 4 years of experience managing reliability, scalability, and availability for large-scale production services with deep expertise in programming (e.g., Python, Go, or C/C++) • Strong background in networking protocols, Linux/FreeBSD systems, and distributed architecture • Experience in high-stakes incident management and participation in a 24/7 on-call rotation • Proficiency in leveraging ITIL frameworks and incident data to drive service maturity through systematic problem management and technical operability reviews What Will Make You Stand Out (Preferred Qualifications) • Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency • Experience implementing AI-driven AIOps tools, machine learning models for anomaly detection, or predictive capacity planning to optimize infrastructure reliability and automate incident response • Extensive experience with public cloud (AWS, Azure, GCP), Infrastructure-as-Code (Ansible, Terraform), and chaos engineering or disaster recovery planning at scale • Expertise in global routing (BGP), traffic tunneling (GRE, IPSec), L7 proxy architectures (HAProxy), DNS at scale, and OS networking stack internals #LI-CM3 #LI-Remote Zscaler’s salary ranges are benchmarked and are determined by role and level.
