What we're looking for:

We need an experienced infrastructure engineer with 7+ years of experience who has led infrastructure projects and is comfortable building and scaling cloud systems (AWS preferred) in a fast-paced startup environment.

- Design and maintain reliable deployment processes, CI/CD pipelines, and infrastructure-as-code for getting models and services into production

- Manage GPU allocation, instance sizing, and cost optimization across cloud resources

- Build monitoring, logging, and automated testing infrastructure that gives the team visibility into what's running, failing, and why

- Own data and ML ops including ETL pipelines from varied customer data sources, model versioning, and lifecycle management

- Drive security engineering including data isolation between customers, infrastructure hardening, and SOC2 compliance

- Mentor and partner with the existing infrastructure engineer to raise the bar for the team
