Research Engineer: Real-Time Voice ML & Production Systems

Sesame is building a future where computers are lifelike, with voice agents that feel natural. We're seeking an ML engineer to own evaluation pipelines, data tooling, and deployment of real-time voice models powering Sesame's companion experience. You will scale training/inference for large models, design robust metrics, and ship end-to-end solutions in a fast-paced startup environment. Collaboration with research, infra, and product is essential; strong autonomy is valued.
