Machine Learning Engineer

We’re hiring on behalf of A1, a high‑talent team building the next generation of AI‑native productivity applications. Their mission is to replace repetitive digital work with AI that can reliably complete real tasks for everyday users. Rather than building another chatbot, A1 is creating long‑running AI workflows that manage conversations, coordinate actions, maintain context, and interact with external services — all with minimal user input. As a Machine Learning Engineer, you will own critical ML subsystems in production. This is a hands‑on, high‑impact role focused on depth and reliability at scale. What you’ll do - Build core ML systems powering a proactive, long‑horizon AI product. - Own the full lifecycle: data preparation, training, evaluation, inference, iteration. - Turn research ideas into production systems that run reliably. - Debug model failures and system issues using
