Join Zendesk and Shape the Future of Employee Service Software

Zendesk’s Employee Service business is the future of the company and a key part of our growth strategy. With strong investment, focus, and executive support, this is an exciting opportunity to work on a team at the center of our Employee Service vision.

The Service Catalog team plays a pivotal role in this transformation, providing a powerful catalog-based experience for HR Service Management (HRSM), IT Asset Management (ITAM), and broader Employee Service solutions. Our goal is to empower organizations to streamline employee requests, automate service fulfillment, and create exceptional workplace experiences—whether employees are requesting IT equipment, HR services, or other internal resources.

We are looking for a Senior Software Engineer with a frontend or full-stack focus to lead the development of structured service catalog user interfaces, automation-driven request workflows, and interactive enterprise service browsing experiences. This role is ideal for engineers who thrive on solving complex UI performance challenges, designing scalable front-end architectures, and building self-service automation experiences for structured request fulfillment.

What You’ll Do

Architect & Develop Scalable Front-End Solutions

  • Design and build enterprise-scale UI components that support structured service request workflows, approval chains, and automated service fulfillment.

  • Architect and implement hierarchical service catalog browsing, structured request bundling, and multi-layered service interaction models.

  • Optimize front-end performance, focusing on load times, rendering efficiency, and client-side caching strategies.

  • Work with GraphQL and REST APIs, integrating structured request workflows, service selection automation, and customized approval routing.

  • Ensure accessibility, responsiveness, and intuitive user experiences across all service catalog features.

  • Contribute to the evolution of Zendesk’s front-end architecture, driving improvements in scalability, reusability, and maintainability.

  • Optimize front-end performance, ensuring low-latency request interactions, real-time UI updates, and scalable service fulfillment experiences.

Lead Technical Innovation & Collaboration

  • Work closely with Product Managers, Designers, and Engineers to create user-friendly, configurable service catalog UI components.

  • Lead system design reviews and UI architecture discussions, influencing best practices for service request workflow UX and automation-driven interactions.

  • Enhance developer experience by contributing to design system optimizations, UI performance frameworks, and automation-driven interaction models.

  • Experiment with new front-end technologies, advocating for improvements in extensibility, scalability, and real-time service request execution.

Mentor & Strengthen the Engineering Team

  • Act as a technical mentor, helping junior engineers grow their front-end expertise.

  • Conduct code reviews, ensuring high-quality, maintainable, and testable front-end code.

  • Foster a culture of collaboration, knowledge sharing, and continuous learning within the team.

What We’re Looking For

Required Qualifications

  • 5+ years of professional experience in frontend or full-stack development, with a focus on enterprise service catalogs, structured service request automation, or interactive service browsing interfaces.

  • Strong expertise in JavaScript, TypeScript, React, and Redux, with experience in state management for structured workflows and interactive request models.

  • Experience building and optimizing GraphQL and REST API integrations, ensuring efficient data fetching, request fulfillment interactions, and service selection UI responsiveness.

  • Deep knowledge of component-based front-end architectures, optimizing UI workflows for structured service request lifecycle automation.

  • Proven experience developing user-friendly, hierarchical catalog browsing interfaces with search, categorization, and nested service relationships.

  • Familiarity with front-end build tools (Webpack, Babel, Vite) and performance profiling tools.

  • Proven ability to drive front-end architecture improvements and optimize complex UI applications.

  • Experience building and maintaining high-scale, enterprise-grade UI applications.

  • Excellent problem-solving, critical thinking, and collaboration skills.

  • Strong verbal and written communication skills, with the ability to clearly explain technical decisions.

Preferred Qualifications

  • Experience building self-service portals, structured catalog browsing UIs, or request fulfillment workflow interfaces.

  • Familiarity with micro frontend architectures, UI extensibility models, and enterprise-scale front-end scalability strategies.

  • Experience working with observability tools (e.g., DataDog) and optimizing UI responsiveness for structured workflows.

  • Previous contributions to open-source UI frameworks, request lifecycle automation tools, or enterprise self-service interaction models.
