We are the leading AI-native community management performance platform that enables owners and operators, community management teams, boards and associations to work smarter, faster, and with unprecedented insight. More than just accounting and management software, Vantaca is intelligent business operating software that leverages artificial intelligence to automate routine work, surface actionable insights, and help our customers increase revenue, efficiency, flexibility, and control.

Built on modern cloud architecture with a single-platform design, Vantaca combines comprehensive functionality that adapts to 100% of business processes with AI-powered automation that learns and improves over time. Our proactive AI capabilities don't just report on what happened; they predict what's coming and recommend what to do next. From intelligent document processing and predictive analytics to automated workflows and conversational interfaces, we're transforming how community management companies operate.

With seamless integrations across the software and banking ecosystem, we're building the intelligent hub for community management where AI doesn't just assist, it anticipates. Vantaca is focused exclusively on community management and is the trusted technology leader defining the AI-powered future of the community association management industry. We're building something fundamentally different, and our customers are experiencing the competitive advantage that comes from working with truly intelligent software.

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.

We're building the category-defining platform for community association management: 6M+ doors, 100% YoY growth, and an AI product that went from $0 to millions in revenue in months. We're not running a legacy modernization program. We're revolutionizing the industry with AI, building what it will run on for the next decade.

We're expanding our engineering hubs in Raleigh-Durham and Wilmington and looking for Senior Engineers who have mastered the craft of building high-performant applications and are energized by AI and the reality that AI agents are transforming how entire industries operate.

Requirements

• 3+ years of engineering experience building high-performant applications
• Deep fundamentals: distributed systems, concurrency, queuing/workers, caching, production operations
• Strong relational data modeling: Postgres or SQL Server, migrations, indexing, query optimization, correctness at scale
• API design discipline — clear, evolvable contracts across services and external partners
• Polyglot experience with TypeScript, Python, or equivalent cloud-native tooling
• LLM orchestration experience: prompting, tool calling, evals, latency/cost tradeoffs

• Implement high-quality integrations (OAuth, webhooks, sync engines, connectors) with strong observability and failure handling
• Define SLIs/SLOs, implement end-to-end tracing, build circuit breakers and cost guardrails for agent workloads
• Optimize throughput, latency, queue backlogs, caching, and storage as the platform scales
• Drive engineering standards: code quality, testing strategy, on-call hygiene, runbooks, and postmortems
