About Brain Co.
Brain Co. builds AI-native operating systems for large, regulated institutions. Each system is built for a specific industry, powered by agents that push real workflows forward.

Diagnose and improve performance across distributed systems and AI workloads.
Support high-performance inference, data pipelines, and large-scale backend services.
Ensure systems scale reliably under fast-growing and unpredictable workloads.
Partner with technical leaders on architecture and mentor engineers.

Compensation
We pay competitively for every role and back that with meaningful equity, because we want the people building Brain Co. to genuinely share in what we build together. Beyond salary and equity, we invest in country-specific benefits because we want our team to feel taken care of, not only compensated.
The annual base salary range for this role is $180,000 - $325,000. We publish this range for every role, as a matter of policy regardless of whether local law requires it. Actual pay will depend on skills, scope, and experience.
