• Demonstrated ability to design robust client experiences around network latency, graceful degradation, and dynamic model responses.
• Track record of shipping and supporting consumer-facing production apps in the App Store.
• Familiarity with on-device ML frameworks (e.g., CoreML) and feature flagging setups.
• Strong product intuition focused on mobile UX and client-side reliability.

Reasons to join:

• Small founding team, building a greenfield AI email product from scratch.
• High‑caliber engineers from top tech companies; very high technical bar.
