Full Stack Software Engineer (Vibe Coder)

Compensation: 0.0% – 4.0%

About Us

Zer0paper OÜ builds technology products across developer tools and fintech. We are currently shipping a mobile-first escrow and verified logistics platform for e-commerce in Nigeria — secure payments, real-time delivery tracking, and dispute resolution backed by licensed financial infrastructure.

The Role

You will join an active codebase with backend services, integrations, and mobile app work already underway. Your job is to complete features, write tests, fix bugs, and ship a production-ready product. You will work primarily with Claude Code as your development tool — proficiency with AI-assisted development is essential, not optional.

Responsibilities

• Complete in-progress features across a Go backend and Flutter mobile application
• Write and maintain tests — unit, integration, and end-to-end
• Implement and refine payment flows, escrow logic, delivery tracking, and user verification features
• Work with existing integrations — payment processors, SMS/notification services, GPS tracking
• Debug, troubleshoot, and resolve issues across the full stack
• Maintain code quality and security standards appropriate for a financial product

Requirements

• Working proficiency in Go and Flutter/Dart
• Experience with Claude Code or strong demonstrated ability to ship production software using AI-assisted coding tools
• Critical thinking — you can read existing code, understand intent, identify gaps, and make sound decisions
• Familiarity with payment APIs, escrow flows, or fintech compliance is a plus
• Comfortable working asynchronously with minimal supervision

Compensation

Short-term contract with instant equity activation upon delivery of shipped projects. You ship, you own.
