Product Engineering Lead

About the role

Tether is building QV.AC, a privacy‑preserving AI assistant that runs locally on users' devices. As the Product Engineering Lead you will turn product vision into high‑quality features that work reliably on real devices with strict performance constraints.

Key responsibilities

• Lead app and feature teams day‑to‑day, removing blockers, reviewing code and ensuring continuous delivery.
• Set and maintain a high engineering bar for performance, reliability and clean API design.
• Own technical design of features and the API surface between the AI core and the application.
• Collaborate closely with AI research and deep‑tech teams on code reviews, model integration and inference constraints.

Required profile

• Proven experience managing engineers or engineering leads who ship consumer‑focused products, preferably AI‑powered apps.
• Strong product sense with the ability to evaluate feature value versus complexity.
• Intuition for applied on‑device AI constraints such as model size, latency, memory and battery.
• Hands‑on attitude: roll up sleeves when needed and mentor team leads to improve operating systems.

Required skills

• Deep JavaScript expertise.
• Strong React development experience.
