Staff Infrastructure Engineer, Cloud & Reliability

The posting, as Vantaca wrote it

HOAi is the fastest-growing company revolutionizing the community association management industry. Our AI workforce platform integrates machine learning technology to streamline labor-heavy processes, eliminating inefficiencies and driving scalability. With rapid growth in the AI space, we are pushing boundaries to redefine industry standards. HOAi Agents go beyond traditional AI by proactively executing complex, multi-step processes with human-like reasoning—working autonomously, 24/7, across your entire operation. This transformation optimizes labor costs, enables growth without additional hires, and ensures faster, higher-quality service for residents and board members.

HOAi was acquired by Vantaca in the fall of 2024. Vantaca just achieved unicorn status with a $1.25B valuation, so it's safe to say we're past the "scrappy startup phase." We're not just building a successful company – we're building the category-defining platform that will transform how an entire industry operates.

Here's the reality of our trajectory

• Growing 100% year-over-year
• Our AI product (HOAi) went from $0 to millions in months
• Backed by Cove Hill Partners and JMI Private Equity
• 6M+ doors on our platform, displacing legacy systems

Overview

You 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, Diagnos
