We are seeking a Senior Svelte Front-end Developer with experience in Golang (so that they are full-stack). It is essential that the person is highly product-driven, self-motivated, speaks excellent English, and enjoys using coding AI tools like Claude Code.
Our stack:
- Frontend: SvelteKit, turbo monorepo, Vercel
- Backend: Golang monorepo
- AI: Claude Code (mandatory), other agentic coding tools
What you'll actually do:
- Own features end-to-end: from specs to deployment to fixing bugs
- Use Claude Code to generate SvelteKit frontend and Golang backend code
- Review AI output for quality and architectural fit
- Fix bugs to learn our codebase, then rapidly build new features
- Make quick decisions on what to build vs buy vs generate with AI
- Talk to customers when they report issues and ship fixes the same day
You must have:
- Ownership mentality with a strive for elegantly simple, high-quality solutions
- Strive for max quality - you test your own work thoroughly since we have no QA team, everything you ship MUST work
- Product mindset - you care about WHY we're building something
- Proven experience using Claude Code or similar agentic AI (Cursor, Windsurf)
- Strong SvelteKit and Golang experience - you'll review AI's code in these, and you must understand how it works
- Broad architectural knowledge of building modern full-stack applications
-
Excellent spoken English and a good internet connection for daily video calls
You are a great fit if you:
- Get frustrated when development takes weeks instead of days
- You think in features and architecture, and not single lines of code
- Can spot subtle bugs in AI-generated code quickly
- You ship fast, but always verify it actually works
- Have shipped real products that customers actually use
- Think "how can AI build this?" as your first instinct
‼️ Red flags (don't apply if):
- You've never used Claude Code or similar AI coding tools
- Your English is intermediate
- You need detailed specs before starting
- You see AI as a threat rather than leverage
