Senior Mobile Developer (Flutter / GCP / AI)

We are looking for an autonomous Senior Developer to take end-to-end ownership of the mobile ecosystem for a US-based client—spanning from initial concept and UX/UI design to deployment and long-term maintenance. This is not a role for a simple "task executor." We need a product-minded engineer who actively proposes solutions, optimizes architecture, and ensures technology effectively serves the product’s business goals. Details • Start Date: Late May 2026. • Duration: ~12 months (with a high likelihood of extension). • Client: USA (requires C1 English and comfort working in a distributed, international team). • Seniority: Senior (requires full end-to-end autonomy). Responsibilities • Full-cycle Mobile Development: Build and scale mobile applications using Flutter and FlutterFlow. • Product Engineering: Actively participate in UX/UI design and the definition of new product features. • Cloud & Infrastructure: Manage the application’s backend infrastructure on GCP (Google Cloud Platform) and integrate with third-party providers (e.g., Okta). • AI Innovation: Implement and experiment with Google AI services to enhance the product's capabilities. • Quality & Optimization: Lead testing, debugging, and continuous performance optimization for production readiness. Requirements • Mobile Mastery: Expert knowledge of Flutter and hands-on experience with FlutterFlow. • Cloud Infrastructure: Proven experience with GCP services. • Identity & Security: Practical experience with Identity Providers (specifically Okta). • Language: Business-fluent English (C1) for direct, daily collaboration with the US team. • Nice to Have: Familiarity with Google AI tools (e.g., Vertex AI, Gemini API) and a strong eye for mobile UX design.
