O projekcie:
Mobile Developer (.NET) — 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
- up to 6,000/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.
Wymagania:
- 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.
Codzienne zadania:
- 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.
