We are looking for an AI-First Full-Stack Engineer: Golang Backend, Svelte (or any other frontend technology) Frontend. We don’t need coders, we need engineers who build features end-to-end using Claude Code.

Key highlights:

• AI coding experience (mandatory!): experience with Claude Code — #1 priority, or other agentic coding tools. Claude Code is what is used on the project
• Full-Stack Engineer with 5+ years of experience. We also consider really strong candidates with 4 years of experience
• Backend experience with Go is a primary requirement; frontend experience comes secondary.
• Svelte is the preferred frontend technology for this project, but candidates with other frontend experience are considered as well.
• Strong proficiency in English (Strong Upper-intermediate level or Advanced)
• Full-time
• Fully remote
• Start: ASAP, ideally, but can be discussed
• Long-term project

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

Our stack:

• Frontend: SvelteKit, turbo monorepo, Vercel
• Backend: Golang monorepo
• AI: Claude Code (mandatory), other agentic coding tools

Products you will build:

• API: platform features, tooling, multi-agent system, etc.
• UIs: internal UIs, B2B dashboards, B2C web apps

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
• You’re a perfectionist who loves to code
• You need detailed specs before starting
• You see AI as a threat rather than leverage
