Ready to build something meaningful?

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

We are looking for an AI-First Golang Developer. We don’t need coders, we need Golang backend engineers who build features end-to-end using Claude Code.

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 Golang Developer, 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, ideally, or can be discussed. 1 month’s notice will not work.

What you’ll actually do:

• Own features end-to-end: from specs to deployment to fixing bugs
• Use Claude Code to generate 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:

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

Products you will build:

• API: platform features, tooling, multi-agent system, etc.

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 Golang experience — you’ll review AI’s code in these, and you must understand how it works
• Broad architectural knowledge of building backend
• 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 the European timezone
