We're building the AI foundation for a company operating at billion-user scale. As Head of AI Engineering, you own everything that lets 200+ Data Scientists and MLEs ship models to production fast, reliably, and cost-efficiently.

If training is slow, serving is down, GPUs are idle, or models take 6 months to ship — that's on you. If we 10x ML iteration speed and cut infra costs 50%, that's also on you.

This is a 0-1 build: we have the mandate, budget, and headcount. We need you to set the vision and hire the team.
