Senior Frontend Developer (SvelteKit)
EU remote | Senior Frontend (SvelteKit + Tailwind). Architect a performance-first frontend from scratch: sub-second loads, CWV targets, design system ownership.
We usually respond within a week
Location: Fully Remote from Europe
Daytime Schedule
We are hiring a Senior Frontend Engineer to design and build a new web frontend from the ground up using SvelteKit and Tailwind CSS. The mandate is a performance first rebuild: sub-second load times, excellent Core Web Vitals and a clean architecture that the team can scale on for years.
You will own frontend architecture decisions, set the standards for the codebase, and work directly with product, design, and backend to ship a fast, accessible, SEO-strong web experience. You will also be expected to work fluently within an agentic AI development workflow, using AI coding agents as a core part of how you ship.
