Job description

We're looking for an Android Software Engineer to build the mobile experience that brings this vision to life.

The Opportunity

This isn't a typical mobile role where the app is simply a front end.

You'll own how AI feels, behaves and performs on Android, building production-ready experiences that users depend on every day. From streaming AI conversations and voice interactions to intelligent recommendations and long-running workflows, you'll help define what an AI-native mobile experience should be.

If you're excited by building products at the intersection of mobile engineering and AI, we'd love to hear from you.

What You'll Be Doing

• Build and maintain high-quality Android applications using Kotlin
• Develop AI-powered experiences including chat, voice, vision and intelligent recommendations
• Design seamless user experiences for streaming responses, retries and long-running AI interactions
• Optimise application performance, responsiveness, memory usage and battery efficiency
• Collaborate with backend and machine learning engineers to shape APIs and product behaviour
• Implement analytics, monitoring and feedback mechanisms to continuously improve AI performance
• Deliver secure, scalable and reliable production applications

What We're Looking For

• 3+ years of Android development experience using Kotlin
• Experience integrating AI capabilities such as LLMs, vision or speech APIs
• Strong knowledge of Coroutines, Flow and asynchronous programming
• Experience working with REST or gRPC APIs
• Excellent debugging, profiling and performance optimisation skills
• Experience building resilient applications that handle latency, partial failures and unpredictable responses gracefully

Bonus points if you have experience with:

• ML Kit or TensorFlow Lite
• On-device machine learning
• Applications published to the Google Play Store
