Senior Frontend Developer

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.

Responsibilities

• Architect and build a new web frontend from scratch using SvelteKit and Tailwind CSS

• Define rendering strategy across SSR, SSG, ISR, and edge where appropriate

• Hit and hold performance targets: LCP < 2.0s, INP < 200ms, CLS < 0.1 on real-user metrics

• Build a reusable component library and design system implementation in Svelte

• Translate product requirements and design specs into clean, composable, accessible components

• Own SEO fundamentals: semantic HTML, metadata, structured data, sitemap, canonicalization

• Set up and enforce testing standards: Vitest for unit, Playwright for E2E

• Establish frontend tooling and DX: linting, formatting, type checks, pre-commit hooks, CI gates

• Lead code reviews and raise the quality bar across the frontend

• Drive technical planning, ADRs, and architecture discussions

• Integrate with backend APIs and contribute to API contract design where it affects the frontend

• Support CI/CD pipelines and deployments on AWS

Required Skills

• Strong production experience with Svelte and SvelteKit

• Expert-level TypeScript and modern JavaScript

• Deep Tailwind CSS experience, including design token strategy and avoiding utility sprawl

• Strong HTML5, CSS3, accessibility and responsive design

• Proven track record building high-performance web apps measured against Core Web Vitals

• Experience designing scalable frontend architectures from greenfield

• Experience building and maintaining reusable component libraries

• State management patterns in Svelte (stores, context, runes)

• Vitest for unit testing

• Playwright for end-to-end testing

• Strong Git and GitHub workflow proficiency (PRs, reviews, CI/CD)

• Experience with performance monitoring and optimization (Lighthouse, WebPageTest, RUM)

• Hands-on experience implementing agentic development workflows using tools such as Claude Code, Cursor or equivalent.

Nice to Have

• Experience with edge runtimes (Cloudflare Workers, AWS Lambda@Edge)

• Experience deploying to AWS (CloudFront, S3, ECS, or equivalent)

• Experience with CI/CD pipelines

• Experience implementing design systems end-to-end

• Experience integrating AI-powered features into production frontends

• Prior experience migrating from React/Next.js to Svelte/SvelteKit
