Senior Android Engineer (Fully Remote - £100k+)

Senior Android Engineer | Fully Remote | £100k-£120k

A fast-growing AI company with $100m+ in funding is building a new generation of AI-native applications designed to change how people manage work and everyday life.

Rather than another chatbot, the product is a unified AI workspace connecting email, Slack, Lark and other communication platforms, with AI agents capable of coordinating tasks, conversations and scheduling autonomously.

The Role

We're looking for a Senior Android Developer to own the mobile experience and help define how AI feels, behaves and performs on mobile.

You'll be building a production AI application where streaming, latency, reliability and non-deterministic behaviour are fundamental to the product.

What You'll Do

• Build and maintain production Android applications using Kotlin.
• Integrate LLMs, voice, vision and AI-powered features through backend APIs.
• Build UX for streaming responses, retries, partial results and long-running workflows.
• Work closely with backend and ML engineers on APIs and system behaviour.
• Optimise performance, memory usage and responsiveness.
• Implement analytics, logging and feedback mechanisms to improve AI performance.
• Explore on-device AI using MLKit / TensorFlow Lite.

What We're Looking For

• Hands-on experience integrating AI/ML features, such as LLMs, speech or vision.
• Strong Coroutines and Flow experience.
• Experience with REST/gRPC APIs.
• Strong debugging and performance profiling skills.
• Comfortable building products dealing with latency, partial failures and non-deterministic behaviour.
• Experience with MLKit or TensorFlow Lite is a plus.
• Experience shipping production apps to the Google Play Store.

Why Join?

You'll be joining a $100m+ funded AI company and working on a product where AI is the core experience, not an add-on.

You'll have genuine ownership over the Android architecture and the way users interact with autonomous AI agents on mobile.
