Kotlin developer

We are looking for a highly efficient Mid-level Mobile Developer for a project focused on rapid iteration and modern architecture. The core mission? Build and refine mobile experiences while leveraging Gen AI tools to accelerate the development lifecycle. If you’re a mobile-first developer who treats Supabase as their go-to backend and isn't afraid to use Claude Code (or similar) to multiply their output, this is the perfect opportunity for you.

Details

• Duration: ~3 months (Initial contract until May 2026, with potential for extension).

• Rate: 100 – 120 PLN/h net + VAT (B2B).

• Model: 100% Remote.

• Intensity: Full-time engagement.

• Language: English (min. B2 – clear communication is key).

Responsibilities

• Mobile Development: Drive the mobile layer forward (strong mobile fundamentals are more critical here than specific Kotlin/KMP mastery).

• AI-Augmented Coding: Use Gen AI tools (like Claude Code, GitHub Copilot, or Cursor) to streamline workflows, generate boilerplate, and solve complex logic faster.

• Backend Integration: Work seamlessly with a Supabase backend to handle data, authentication, and real-time features.

• Rapid Delivery: Move from concept to feature in record time, maintaining a high level of independence.

Requirements

• Mobile Heavyweight: You have a solid, proven background in mobile app development.

• AI Fluency: Practical experience integrating Generative AI into your coding workflow (you know how to prompt and iterate with AI to save time).

• Supabase Knowledge: You’ve built and shipped projects using Supabase as the backend layer.

• Independence: You don't need your hand held; you see a task, find the most efficient way to do it, and execute.

• Mindset: You value speed and "working smart" over just "working hard."
