Software Engineer, Desktop

A1 is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior.

You will own how this system behaves on desktop environments. Your work focuses on reliability, performance, and real-time behavior in production desktop applications.
