About the role

Sonder is seeking an inference and performance engineer to own the systems layer between our models and the hardware they run on—starting with Apple Silicon and macOS. You will make our models faster, smaller, and more power-efficient through kernel optimization, memory layouts, and quantization. You will work closely with researchers to co-design inference systems, profiling from workloads to measured improvements, and shipping reliable local inference stacks across the Mac platform.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
