Job summary

Navi AI in San Francisco is seeking a production infrastructure engineer to own and scale our AWS platform. You will manage data ingestion, AI pipelines, and customer dashboards, ensuring reliability at 100,000+ users and 100 requests per second.

You will drive monitoring, failover design, cost optimization, and maintain runbooks and documentation, collaborating across backend teams to push our infrastructure forward as Navi expands into new customers like flight schools and defense partners.

Qualifications

• 5+ years building and operating production infrastructure.
• You've dealt with user data and processing at genuine scale: 100,000+ users and 100 requests per second.
• Deep, hands-on AWS experience: you know the services, the failure modes, and the bill.
• You've built observability from scratch: monitoring, alerting, on‑call, incident response.
• You've shipped automatic failover and fallback mechanisms and lived with them in production.
• You treat cost as an engineering metric and have materially reduced cloud spend at scale.
• Strong backend skills; you're an engineer first, infrastructure specialist second.
• You write things down: documentation and runbooks that let others operate what you built.

Responsibilities

• Own and scale the AWS infrastructure behind Navi's platform, from data ingest to AI pipelines to customer-facing dashboards
• Architect for real scale: 100,000+ users and 100 requests per second
• Build monitoring and alerting so we know a system is degrading before a customer does
• Design automatic fallback and failover mechanisms so a failure never becomes an outage
• Manage infrastructure costs and keep the cost curve flatter than the growth curve
• Own our infrastructure documentation and runbooks, and keep them current and usable
• Contribute across the backend: pipelines, APIs, and services beyond pure infrastructure
