About this role

Senior Mobile Developer Bluegeko Daily tasks: - Mobile app features (iOS/Android or cross-platform) — real, production, shipping code. - Work with Authentication, biometrics, push notifications, and BLE functionality. - API integrations with our .NET/C# backend team. - Direct input into how the app connects to our customer portal, payments, and reporting systems. - Fast decisions, zero bureaucracy—you work directly with the CEO and core team.

Musts: API, Android, iOS What You Bring Proven track record: Live apps you've shipped that are currently in production, with a portfolio or App Store/Google Play links to prove it. Strong senior-level commercial experience—this is not an entry-level role. Comfortable working with APIs and collaborating with a backend team (bonus if you know .NET/C#). Working knowledge of mobile security fundamentals: authentication, permissions, push notifications, and BLE.

Independent, clear communicator who delivers. Based in Warsaw or willing to relocate, and available to start immediately. Senior Mobile Developer — B2B Contract | Warsaw | Start Immediately Full-time In-office Relocation bonus Milestone bonuses The Opportunity 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'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.
