Software Engineer: Backend & Infrastructure

About the role

Your role, should you choose to join us, will be as an Infrastructure / Backend Engineer on our founding team.

You're the right person for this role if you're excited to build not just robust systems, but help shape the technical backbone of a category-defining company from day one.

• Deploying and optimizing AI-heavy services with high availability and performance requirements
• Managing infrastructure as code, cloud environments, and CI/CD pipelines
• Implementing monitoring, observability, and alerting to ensure system reliability
• Contributing to infrastructure security and best practices

You likely have:

• Experience deploying and productionizing ML or AI-heavy workloads
• Expertise in building secure, scalable systems on platforms like AWS, Azure, or GCP
• Deep knowledge of backend systems, networking, and container orchestration (e.g., Kubernetes)
• Familiarity with infrastructure security principles and compliance (e.g., SOC2)
• The mindset of an owner: proactive, hands-on, and driven to solve problems end-to-end

Compensation

• The rare opportunity to join a formidable team to build an enduring company, in person, as a first 20 employee
• Competitive compensation
• Significant equity upside
• Medical / dental / vision

This role is based in person in San Francisco, CA (not remote).
