About the role

Description

Powered by AI, Vantaca's vision is big! 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.

The Opportunity

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.

What You'll Own

This role sits at the core of our platform engineering, building the systems that make Vantaca dependable at scale.

Platform & Agent Systems

Build and operate the backend systems powering AI agents in production: tool execution, state management, orchestration, retries, idempotency, and rate limiting
Design robust, agent friendly APIs as interfaces for internal and external consumers
Model complex domain data — agent memory/state, workflow history, audit trails, permissions, multi-tenant isolation
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

What We're Looking For

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
Agent architecture familiarity: orchestration patterns, planning/execution loops, memory/state, sandboxed tool execution
Experience with message-based architectures or equivalent event-driven patterns

You'll thrive here if

You're energized by the business problems you're solving and you want to define, design, and own outcomes end-to-end
You build in quality and ship fast without sacrificing re
