    AI-First Full-Stack Engineer (Golang, any frontend tech, Claude Code)

    Full Remote · Countries of Europe or Ukraine · 5 years of experience · English - B2
    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...

    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
