Member of Technical Staff, Machine Learning

A1 is building a proactive AI smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows.

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.

As a Member of Technical Staff, Machine Learning, you will build core ML components. You will work on real production systems from day one, learning how large‑scale ML behaves outside of research settings. This role is for engineers who want to develop strong systems judgment by shipping, debugging, and iterating on real‑world ML.

• Build and improve ML components across data, training, evaluation, and inference.
• Fine‑tune and adapt models as part of larger production systems.
• Implement evaluation and testing to under...
