Senior Frontend Engineer

The Opportunity

Canals is growing quickly, and the complexity of what we’re building is too. We’re looking for a Senior Frontend Engineer to help us design and build rich, performant web applications that make intricate supply-chain operations simple and intuitive.

You’ll own major parts of our frontend architecture, collaborate closely with product and design, and bring beautiful, highly-usable experiences to life. This is a high-impact role for someone who loves turning messy real-world workflows into elegant, reliable interfaces.

What You’ll Do

• Build and maintain core frontend features using Svelte, TypeScript, and modern web tooling.
• Own large, complex UI projects end-to-end — from architecture and implementation to polish and performance.
• Collaborate with product designers and backend engineers to translate business logic into intuitive interfaces.
• Shape and evolve our design system and component libraries for consistency and speed.
• Optimize performance, accessibility, and reliability across browsers and devices.
• Review code, mentor teammates, and help raise the overall technical bar of the frontend team.

What You'll Bring

• Typically, 5+ years of professional experience in frontend or full-stack engineering.
• Expert-level knowledge of TypeScript, and modern JavaScript/HTML/CSS.
• Proven experience shipping complex, data-driven web apps in production.
• Deep understanding of frontend architecture, state management, and API integration patterns.
• An eye for design and empathy for users — you care about how things look and feel.
• Strong communication and collaboration skills in a remote, async environment.
• Experience with frontend performance optimization is a plus.
