Job description

Overview

Vantaca is a leading AI‑native community management performance platform that empowers owners, operators, community management teams, boards, and associations to work smarter, faster, and with unprecedented insight. Leveraging artificial intelligence, Vantaca automates routine work, surfaces actionable insights, and helps customers increase revenue, efficiency, flexibility, and control.

The Opportunity

We are building the category‑defining platform for community association management. With 6M+ doors, 100% YoY growth, and an AI product that scaled from $0 to millions in revenue in months, we are revolutionizing the industry with AI and expanding our engineering hubs in Raleigh‑Durham and Wilmington.

What You’ll Own

• 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 post‑mortems

What We’re Looking For

• 3+ years of engineering experience building high‑performant applications
• Deep fundamentals in distributed systems, concurrency, queuing/workers, caching, and 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 want to define, design, and own outcomes end‑to‑end
• You build in quality and ship fast without sacrificing reliability or security
• You hold a high bar for data integrity and correctness as the systems you build affect real communities at scale
• You love winning as a team

The Way We Work

• Shoot for Impossible, Make it Happen — we set audacious goals, break them into executable steps, and don’t flinch at hard problems
• Radical Candor, Humble Excellence — direct feedback, genuine care, no politics
• AI‑accelerated velocity — we expect innovative use of AI development tools

Core Values

• Always Growing: quickly learn new ways to improve the product and help the team grow
• Win as a Team: build trust and work together by communicating well and celebrating successes
• Accountability Starts with Me: notice problems and take personal action to solve them
• Unwavering Commitment to Customer Experience: regularly talk to residents and management companies to understand their needs and improve experience
• Innovate Boldly: challenge the status quo and push boundaries to create meaningful change with urgency and purpose

Why You Should Join Our Team

• Build consumer products that millions use; shape how homeowners across the country interact with their communities daily
• AI‑First Product Culture with access to cutting‑edge tools and autonomy to experiment
• Benefits: Medical, Dental, and Vision start day one
• Unlimited PTO with a requirement to take a minimum of one continuous week per year
• 401(k) with Company Match
