Ready to make an impact at the company pioneering security transformation in the AI era? Join us at Zscaler.

Role

What You'll Do (Key Responsibilities)

• Build Performant, Secure Tooling: Implement security-sensitive logic that runs on every page load with minimal overhead. You must care deeply about latency, memory consumption, and ensuring the browsing experience is never degraded
• Write Quality, Maintainable Code: Produce highly readable, modular code that follows established patterns and conventions, while actively participating in and elevating team code reviews
• Collaborate Cross-Functionally: Partner closely with UI/UX designers, backend engineers, and QA to ship features end-to-end, maintaining clear communication regarding progress and blockers

Who You Are (Success Profile)

• You Think at Scale: You connect your day-to-day work to the larger company mission and think globally. You build solutions, processes, and architectures that are not just effective today, but are built to last and support a high-growth organization
• You are Driven by Innovation: You possess a deep curiosity for how things work and are energized by solving complex technical hurdles. You believe in the power of technology to accelerate transformation and consistently hunt for more secure, scalable methods
• You are a Problem-Solver: You actively seek out engineering challenges because you are energized by finding solutions, knowing that solving the hardest problems delivers the biggest business and customer impact
• You are Data-Driven: You lean on data and analytics to uncover engineering truths, measure what matters, and guide informed architectural decisions replacing "I think" with "I know."
• You are a Learner: You have a true growth mindset and never stop developing your technical or leadership skills. You actively seek and implement feedback to become an exceptional collaborator and teammate

What We're Looking For (Minimum Qualifications)

• Experience with at least one modern frontend framework or reactive UI library (e.g., React, Vue, Svelte); ability to pick up new frameworks quickly
• Proficiency with HTML5 and CSS3, including building responsive, component-based UIs
• Demonstrated curiosity and active exploration of AI tools, with a proven history of integrating new technologies to enhance daily workflows and augment problem-solving

• A basic understanding of web application security risks (XSS, CSRF, content isolation) and safe coding practices, combined with exposure to Node.js for tooling, scripting, or API integration
