Zscaler is looking for an experienced Principal Software Engineer to lead the delivery of innovative API tooling and frameworks. This role is important to creating a world-class developer experience by building tools and frameworks that allow seamless UI creation, integration and binding data sources represented by APIs. The Principal Engineer in this role will work with cross-functional teams, including UI/UX engineers and Data Engineers, to expedite the development of new services and UI components using modern technologies like generative AI for some workflows.

The Principal Software Engineer will also create tooling and client SDKs that facilitate the binding of data sources to UI and client-side components, thereby shortening the time it takes to build Zscaler applications. This requires developing frameworks that support UI construction using modern patterns such as MVC, MVVP, binding data sources, and integrating components built on design systems, including Material Design. On the backend services side, there is a focus on accelerating the creation and deployment of new APIs and related tooling to promote the aforementioned UI components. Collaboration with product managers and engineering teams is necessary to ensure that the tools and frameworks developed align with Zscaler's strategic goals, balancing rapid development cycles with long-term maintainability and scalability.

We're looking for an experienced Principal Software Engineer to join our API Team. Reporting to the Director, Software Development Engineering, you'll be responsible for:

Lead the design and implementation of advanced API tooling and frameworks, ensuring UI creation and seamless integration with Zscaler's API services.
Develop client SDKs that provide easy-to-use interfaces for data binding and UI component integration, applying modern UI frameworks and design patterns.
You will improve the space of UI and API integration, using new approaches like generative AI to automate and enhance the development of UI components.
Participate in hands-on coding and development, focusing on creating tools that improve developer productivity and refine the API development process.
Use domain-driven design principles to align tooling and framework development with our needs and technical goals.
Mentor engineering teams on best practices for building frameworks and API tooling, encouraging an inclusive engineering culture and collaborate with UI/UX engineers to build backend systems that support scalable, maintainable, and performant applications.

What We're Looking for (Minimum Qualifications)

Proficiency plus 10+ years of experience in at least one programming language (Go, Java, C++, Rust, Go, Javascript etc.)
Experience (7+ years) in building frameworks and tooling for API and UI development, with a focus on enhancing developer experience and productivity.
Experience with API design standards, best practices (e.g., Swagger/OpenAPI 3.0, REST, JSON, gRPC, Protobuf), and API-first design principles.
Proficiency in modern UI design patterns (MVC, MVVP, etc.) and experience with popular front-end frameworks (React, Angular, etc.).
Work with UI/UX engineers and product managers to align development efforts with user needs and team goals.
Leadership and mentoring skills, with a commitment to promoting an inclusive engineering culture.

What Will Make You Stand Out (Preferred Qualifications)

Background in developing client SDKs in general and tooling that facilitates data binding, UI integration, Authz & Authn, using languages such as JavaScript, TypeScript, or similar.
Experience with API tooling and frameworks that promote rapid UI development, with a focus on integration, automation, and testing.
Expertise in domain-driven design and its application in creating scalable and maintainable frameworks.
Experience with container technologies (Kubernetes, Docker, etc.) and cloud computing platforms (AWS, GCP, etc.).
