Role
We are looking for a visionary Principal Software Development Engineer to join our Frontend Engineering team and lead the design, development, and evolution of world-class web applications. Reporting to the Manager of Software Development Engineering, you will play a pivotal role in shaping Zscaler’s next-generation user interfaces.
This is a high-impact leadership role where you will balance hands-on architecture with strategic technical direction, mentoring and guiding other engineers to elevate our overall engineering excellence.
What You'll Do (Key Responsibilities)
- Architect & Deliver: Design and build high-quality ReactJS solutions, specializing in translating complex UI/UX designs into robust, production-ready applications while providing technical mentorship to foster a culture of innovation
- Drive Engineering Excellence: Shape and evolve Zscaler’s core design system. Champion frontend best practices, including modularity, semantic code, comprehensive automated testing, and deep performance tuning
- Cross-Functional Integration: Define clean API contracts and seamless integration roadmaps in collaboration with backend teams. Partner with DevOps to optimize CI/CD pipelines and continuously evaluate emerging technologies
- Scale & Refactor: Lead systematic refactoring efforts to ensure long-term scalability, reliability, and maintainability. Drive engineering excellence with a strong focus on accessibility (a11y) and research-driven methodologies
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: 8+ years of professional software development experience, with 5+ years specializing in large-scale, production-grade ReactJS and Redux applications
- Technical Mastery: Expert-level proficiency in ReactJS development using TypeScript, ES6+, and advanced state management paradigms
- Data Visualizations: Proven experience building highly complex UIs, data-heavy dashboards, and advanced data visualizations (e.g., D3.js)
- Testing Excellence: Deep expertise in developing extensive unit, integration, and E2E testing suites using frameworks such as Jest, Enzyme, or Cypress
- Enterprise Architecture: Proven track record of designing and deploying large-scale enterprise UIs emphasizing high availability, performance, and a seamless global user experience
- AI Tool Integration: Demonstrated curiosity and active exploration of AI tools, with a history of integrating modern technologies to enhance daily workflows and augment problem-solving capabilities
What Will Make You Stand Out (Preferred Qualifications)
- Advanced experience driving performance optimization (speed, responsiveness) using cutting-edge techniques such as lazy loading, code splitting, and tree shaking to enhance application scalability
- Strong familiarity with backend development principles and practical experience using Node.js (or similar) for API integration, tooling, and debugging
- Ability to architect and implement scalable, modular solutions tailored for multi-tenant enterprise applications, ensuring future-proofed system development
