We believe the future of work is Human + AI and are building an AI-native enterprise where human potential is amplified by machine intelligence to solve the world’s hardest security challenges. Driven by deep customer obsession, we are committed to the mission, outcome, and to each other. We bring these commitments to life through three core behaviors: ownership and collaboration, trust through outcomes and impact, and a challenge culture with ongoing feedback. Ready to make an impact at the company pioneering security transformation in the AI era? Join us at Zscaler.

Role

We are looking for an Principal Software Development Engineer (Layer 7 Security & Proxy) to join our team. This is a hybrid role (minimum 3 days a week in Santa Clara, CA office), reporting to the Director, Software Development Engineering in the Zero Trust Exchange department. This architect role is essential to provide technical leadership for the ZIA proxy architecture, with a strong focus on advanced Layer 7 protocols and SSL inspection. You will help improve the quality of code shipped to production by driving sound architectural decisions, implementing innovative solutions, and raising the overall engineering bar for the team. Additionally, you will play a key role in modernizing the ZIA code base by addressing technical debt, fixing existing issues, and rewriting components where necessary. Ultimately, this role is critical for supporting and accelerating the delivery of key proxy roadmap features on a strong and scalable foundation.

Establish reference architectures and design patterns for ZIA components and integrations
Provide technical leadership, mentoring, and architectural governance across virtual and product teams

Who You Are (Success Profile)

You thrive in ambiguity, comfortably building the path as you walk it and viewing dynamic environments as the raw material to create something meaningful.
You are customer-obsessed, building deep empathy for both internal and external users while anchoring your decisions in solving real-world problems.
You are driven by innovation, bringing deep curiosity to complex technical challenges and constantly seeking better, more secure, and scalable solutions.
You think at scale, connecting your daily work to the larger mission to build solutions that support a high-growth, global organization.
You lead with integrity by holding yourself and others to high standards of accountability and building trust through consistent, transparent action.

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
12 + years of experience of total experience and proven experience in designing and implementing networking security software and public clouds infrastructure
Deep understanding of Proxies, HTTP/2, QUIC, TCP/IP, TLS/DTLS and SSL proxies
Proficient in C language
Demonstrated success in designing, optimizing, and troubleshooting high-throughput, low-latency network security products
Bachelor’s degree in Computer Science, Information Technology, or related field

What Will Make You Stand Out (Preferred Qualifications)

Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency
Mastery of TCP/IP, DNS, Http(s), VPN technologies (IPSec, SSL VPN), NAT, and load balancing
Knowledge of BSD/Linux operating systems, virtualization technologies, and DPDK or similar kernel bypass techniques
