This innovation protects our customers from cyberattacks and data loss by securely connecting users, devices, and applications in any location.

Here, impact in your role matters more than title and trust is built on results. We say, impact over activity. We seek innovators who actively use AI to amplify their impact and who thrive in an environment where we leverage intelligent systems to stay ahead of evolving threats. We believe in transparency and value constructive, honest debate—we’re focused on getting to the best ideas, faster. We build high-performing teams that can make an impact quickly and with high quality. To do this, we are building a culture of execution centered on customer obsession, collaboration, ownership, and accountability.

We value high-impact, high-accountability with a sense of urgency where you’re enabled to do your best work and embrace your potential. If you’re driven by purpose, thrive on solving complex challenges, and want to be part of the team that’s helping to secure the AI age, we invite you to bring your talents to Zscaler and help shape the future of cybersecurity.

Role

We are looking for a Senior Staff Development Engineer to join our Engineering team in a hybrid capacity based in San Jose, CA (three days a week), reporting to the Senior Director, Software Engineering. You will help build the world’s largest cloud security platform, leveraging a multitenant architecture and 100+ patents to support over 15 million users. Your vision and technical expertise will enable organizations worldwide to harness speed and agility through a cloud-first strategy.

What you’ll do (Role Expectations)

  • Design, develop, and optimize system infrastructure including networking and security features to support high-performance applications

  • Ensure federal certifications such as FIPS, FedRAMP, Common Criteria, and SOC2 compliance

  • Create design and functional specification documents while performing unit testing and automation to ensure quality

  • Collaborate with cross-functional teams to resolve system-related issues, optimize performance, and innovate features to expand system capabilities

  • Apply strong software design principles to deliver reliable, scalable, and impactful product improvements

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.
