OverviewYou will own the reliability, performance, and cost of the production infrastructure behind HOAi's AI products. Our agents make decisions that property managers act on and our voice agents talk to residents in real time - which means downtime and latency are not abstractions here, they're customer conversations that fail.
This is a hands-on senior role with real ownership. You'll set the reliability bar for a platform growing fast enough that last quarter's architecture is already under strain, and you'll be the person other engineers come to when production behaves in ways nobody predicted.
What You'll Own- Cloud Architecture & Infrastructure as Code: Design and evolve our AWS architecture. Own our infrastructure-as-code footprint, environment topology, and the standards that keep it coherent as the org grows.
- Reliability & Incident Response: Own our uptime posture end to end: autoscaling policies for variable workloads, failover and graceful degradation, circuit breakers and retry semantics, disaster recovery with tested restore paths. Participate in and improve our Sev1/Sev2 process, run post-mortems, and drive the follow-through that keeps the same incident from recurring.
- Observability: Own monitoring, logging, tracing, and alerting across the stack. Build dashboards that answer questions rather than decorate walls, and tune alerting so that a page means something. Extend observability to token consumption and model spend so AI cost is a first-class operational metric.
- Production Database Operations: Own PostgreSQL and Redis as production infrastructure: instance sizing and topology, replication and read replicas, connection pooling, failover and point-in-time recovery, version upgrades, Diagnose query pathology when it surfaces as an incident and partner with product pods on the fix.
- Cost Efficiency: Treat infrastructure spend as an engineering problem. Instrument it, attribute it, and reduce it without trading away reliability.
- Security Posture: Own runtime security for our infrastructure: IAM and least privilege, network boundaries, secrets management, patching cadence, and vulnerability remediation. Support security audits and produce infrastructure control evidence.
Expectations for Success- Uptime and error budget performance for mission-critical services
- Time to detect and time to resolve for production incidents
- Recurrence rate of previously post-mortemed failures
- Infrastructure cost efficiency, including cost attribution by workload
- Database performance and headroom under growth
- Alert signal-to-noise and on-call load
RequirementsRequired
- 8+ years in infrastructure engineering, SRE, or DevOps
- Deep AWS expertise, with production ownership rather than adjacency
- Infrastructure as code in production at scale
- Production operation of PostgreSQL - not just querying it, but sizing, tuning, replicating, and recovering it
- Real on-call experience for a system with meaningful uptime expectations
- Demonstrated cost optimization work with numbers attached
- Strong debugging instincts in distributed systems: able to reason from symptom to root cause without a runbook
Strongly Preferred
- Cloud security posture work: IAM design, secrets management, audit support
- Experience supporting real-time or latency-sensitive workloads
- Datadog or comparable APM in a primary-owner capacity
- Experience in a company that outgrew its original architecture and had to fix it while running
