Lead Infrastructure and Security Engineer

Key Responsibilities

• Operating the multi-tenant LLM gateway on AWS ECS and ALB, including tenant pools, virtual keys, model allowlists, rate limits, metering and failover.
• Owning the AI provider account lifecycle across pooled subscription capacity: purchasing, OAuth linking and refresh, ban detection, replacement and seat forecasting.
• Owning CI/CD and release engineering — branching policy, preview-to-production promotion, CI gating, rollback — and reviewing infrastructure-affecting pull requests, codifying the standards product engineers follow.
• Owning cross-platform release engineering for the command-line installer, including version pinning, stable and prerelease channels, and macOS and Windows install verification prior to rollout.
• Owning incident response end to end — detection, triage, root cause, remediation and written post-incident reporting — and establishing runbooks and an on-call rotation across time
