Job description

Senior Mobile Developer — B2B Contract | Warsaw | Start Immediately

• Full-time
• In-office
• Relocation bonus
• Milestone bonuses

Overview

We're building a mobile app that talks to real-world access control and operational systems—secure logins, biometrics, BLE-based access, payments, and reporting, all in one platform. We need a hands-on mobile developer to own the app and ship features fast, working side-by-side with our .NET backend team and directly with the CEO.

This starts as a B2B contract with real potential to grow into a bigger, long-term role—architecture, team leadership, the works—if it  it  it's a fit on both sides.

This is a senior-level role only. We need someone with a proven track record—live, shipped apps in production and a portfolio to show it. No juniors, no mid-level.

What’s In It for You

• 6,000 - $6,500 /month (B2B contract).
• Relocation bonus if you're moving to Warsaw.
• Milestone bonuses for major deliveries (first release, key integrations, platform go-live).
• Modern Warsaw office.
• Direct access to the CEO—your work shapes the product.
• Fast-moving, low-bureaucracy environment with genuine long-term growth opportunities.

Start immediately. Interview process takes days, not weeks.
