At ClickUp, you’ll have the opportunity to learn, use, and pioneer AI in ways that shape not only our product, but the future of work itself. Join us and be part of a bold, innovative team that’s redefining what’s possible! 🚀

At ClickUp, collaboration and partnership are at the heart of everything we do. As a Principal Frontend Engineer, you’ll drive the technical vision, design patterns, and scalability of our frontend systems while partnering closely with backend and integrations teams to deliver seamless, performant features. You’ll not only write code but shape the architecture that empowers our engineers to move fast and build with confidence.

You’ll set the bar for engineering excellence by influencing coding standards, driving architectural decisions, and ensuring front-end systems are designed for performance, maintainability, and long-term growth. You’ll collaborate with QA partners to ensure testability and quality are built into every solution, while mentoring engineers across the organization to raise our technical craft.

We’re scaling rapidly, so we’re looking for someone who thrives in high-growth environments, balances pragmatism with architectural rigor, and models our values of ownership, speed, and excellence.

The Role:

• Architect and evolve scalable, high-performing front-end systems in Angular 20+ that power the ClickUp platform.

• Define standards, patterns, and best practices for reusable components, state management, and system performance.

• Partner with product, design, and engineering leaders to shape technical direction and ensure architecture aligns with business needs.

• Lead initiatives to identify and resolve bottlenecks in performance, scalability, and developer experience.

• Champion testability and quality by influencing strategies for unit, integration, and end-to-end testing.

• Provide technical leadership and mentorship, guiding engineers on best practices, architectural trade-offs, and new front-end technologies.

• Drive continuous improvement in tooling, build pipelines, and developer productivity.

• Collaborate across teams (backend, integrations, QA, infrastructure) to deliver cohesive, end-to-end solutions.

Qualifications:

• 8+ years of experience with JavaScript/TypeScript and modern frameworks such as Angular or React.

• Deep expertise in state management (NgRx/Redux), RxJS, and scalable front-end application design.

• Strong understanding of HTML, CSS, accessibility, cross-browser compatibility, and responsive design.

• Proven experience making architectural decisions that balance scalability, performance, and delivery speed.

• Track record of mentoring engineers, influencing cross-team technical strategy, and elevating engineering standards.

• Excellent communication skills, able to influence stakeholders across engineering, design, and product.

• Self-starter with an operational mindset who thrives in fast-paced, high-growth environments.
