Ready to build something meaningful?

Let’s talk. Your next big adventure might just start here.

We don't need coders, we need engineers who build features end-to-end using Claude Code. Without any "hand-coding".

Details: 
 • AI coding experience (mandatory!): experience with Claude Code - #1 priority, or other agentic coding tools. Claude Code is what is used on the project 
• Senior Full-Stack Engineer (SvelteKit Frontend, Golang Backend), 5+ years of experience, can potentially consider really strong candidates with 4 years of experience 
• Strong proficiency in English (Upper-intermediate level or Advanced)
 • Full-time
 • Fully remote
 • Start: ASAP!

Sharing more details about the responsibilities and requirements below.

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 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 appsYou 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
 • You're outside European/African timezones
