About the position

Introduction to the position

As a Mobile SDK Engineer at ToumAI, your mission will be to design, implement and maintain high-performance Voice AI SDKs used inside mobile applications across multiple platforms and technologies. You will work on cross-platform and native SDKs (Flutter, Android, iOS, React Native), enabling real-time voice interactions, agentic workflows and on-device or hybrid execution, with strong constraints on latency, reliability, security and developer experience. Your work will directly impact how external developers integrate ToumAI Voice AI capabilities into their mobile applications.

Your role

• Design and implement mobile SDKs supporting voice capture, streaming, events, actions and lifecycle management. • Develop and maintain SDKs across Flutter, Android (Kotlin/Java), iOS (Swift) and React Native. • Ensure consistent APIs, behaviors and feature parity across all supported platforms. • Optimize SDK performance for low latency, low memory footprint and battery efficiency. • Implement secure communication between mobile SDKs and backend voice services. • Support on-device, hybrid and cloud-based execution modes. • Build SDK abstractions that simplify integration for third-party developers. • Collaborate with Voice AI, backend and platform teams to integrate pipelines and agentic workflows. • Participate in debugging, profiling and optimization on real devices. • Contribute to SDK documentation, samples and integration guidelines.

Your qualifications

• Strong interest in mobile systems and SDK development. • Solid experience in mobile development with at least one of: Flutter, Kotlin/Java (Android), Swift (iOS), React Native. • Experience building SDKs or shared libraries (not only applications). • Strong understanding of mobile constraints: lifecycle, threading, audio, performance and security. • Proficiency in one or more native languages (Kotlin/Java, Swift) is highly valued. • Experience with cross-platform bridges and native bindings is a plus. • Familiarity with real-time audio processing or streaming is a strong plus. • Understanding of networking, security and API design on mobile platforms. • Ability to collaborate with backend, ML and product teams. • Strong problem-solving mindset and attention to detail. • Proficiency in English required; French or Arabic is a plus.

Benefits

At ToumAI, you will build core developer-facing products, not just internal tools. You will: • Own SDK components used by external partners and customers • Work on real-time Voice AI systems under tight constraints • Influence API design and cross-platform architecture • Contribute to both cloud and on-device AI experiences If you enjoy building clean, efficient SDKs that other developers love to use, this role is for you.
