Lead Infrastructure Engineer; HOAi

Description

HOAi is a fast-growing startup 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 is the leading AI solution for the community association management industry, enabling organizations to deploy AI Agents that function like experienced managers. These AI 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 rebuilding 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

The Lead AI Infrastructure Engineer at HOAi is responsible for scaling and maintaining the infrastructure that powers our AI-driven products and services. This role sits at the intersection of infrastructure engineering, machine learning operations, and product development, ensuring our AI systems operate with exceptional reliability, performance, and efficiency. The ideal candidate is someone who gets excited about making AI systems fundamentally faster and more scalable.

You’ll work directly with our engineering and product teams to build the foundational infrastructure that enables HOA to deliver the most advanced AI product in the community association management industry.
