Senior Software Engineer, Front End

Summary

Temporal is revolutionizing how organizations manage distributed systems at scale through our innovative platform. Our UI team builds intuitive, powerful interfaces that make complex distributed systems understandable and usable across both our open-source offering and Temporal Cloud.

We’re seeking a Senior Front-end Engineer (also open to mid-level) to join our UI team and play a key role in building and evolving the user experience for Temporal’s products. In this role, you’ll take ownership of complex frontend features across our enterprise SaaS platform and open-source projects, delivering performant, scalable, and thoughtfully designed interfaces that handle real-time, high-volume system data.

You’ll partner closely with designers, Cloud/SDK/Server engineers, and product leaders to translate complex system behavior into clear, intuitive user experiences, while maintaining high standards for code quality, performance, and accessibility.

What You’ll Do

• Design, build, and maintain high-performance, interactive UIs using Svelte, TypeScript, Tailwind and modern development and build tools
• Own and deliver critical frontend features across:
• Temporal Open Source
• Temporal Cloud
• Developer-facing products
• Internal tools and marketing surfaces
• Focus on reliability and scalability of UI features that grow with the platform
• Build intuitive data visualization experiences that help users understand, explore, and debug complex distributed systems
• Take ownership of frontend components and features from concept through production, including iteration and refinement
• Collaborate closely with a seven-person frontend team to deliver both revenue-driving initiatives and long-term platform investments
• Contribute to extensible, customizable UI architectures that support a wide range of customer use cases
• Participate in code reviews, technical discussions, and design reviews to raise the overall quality of the frontend codebase
• Help guide frontend best practices around performance, maintainability, and accessibility

• Building fast, responsive UIs capable of rendering and interacting with large volumes of real-time data
• Designing sophisticated data visualization and exploration tools that allow users to drill deeply into system behavior
• Creating extensible client-side architectures that support customization and extensibility without sacrificing performance or clarity
• Balancing feature richness with simplicity and performance in complex enterprise applications for distributed systems
• Ensuring frontend systems remain maintainable and scalable as the product and team grow

What You’ll Bring

• Strong experience building modern web applications using TypeScript and component-based frameworks
• Experience with, or strong interest in learning, Svelte
• Proven ability to build performant, scalable frontend systems
• Solid understanding of UI/UX best practices, accessibility standards, and responsive design
• Experience working with real-time data, dashboards, or interactive visualizations
• Strong problem-solving skills and attention to detail
• Comfort owning features end-to-end and collaborating across product, design, and backend teams
• Experience working effectively in a distributed or remote-friendly team environment

Team Highlights

• Work on both open-source and enterprise-grade SaaS products
• Help shape the frontend experience for a platform used to power mission-critical distributed systems
• Solve complex technical problems at meaningful scale
• Collaborate with a highly skilled, thoughtful engineering team
• Make a tangible impact on a growing product and company

We’re building a platform that tackles some of the hardest problems in distributed systems — and we believe the user experience should be just as powerful as the underlying technology. If you’re excited about building elegant frontend solutions for complex systems and want to have real ownership and impact, we’d love to hear from you.

• The estimated pay range for this role is $180,000 CAD - $230,000 CAD.
• Additionally, this role is eligible to participate in Temporal's equity plan.
