Job description

Company Overview

Vantaca is a cloud‑native, AI‑powered community management platform that automates routine work and delivers actionable insights to community associations.

What You’ll Own

Platform & Agent Systems

• Build and operate 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

• 5+ 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, and 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 reliability or security
• You hold a high bar for data integrity and correctness as the systems we build affect real communities at scale
• You love winning as a team

Culture & Values

• Always Growing: Find new ways to improve knowledge and product; learn quickly and help the team grow.
• Win as a Team: Build trust and work together; communicate well; celebrate successes together.
• Accountability Starts with Me: Notice problems and take personal action to solve them.
• Unwavering Commitment to Customer Experience: Understand customer needs and improve processes.
• Innovate Boldly: Challenge the status quo and push boundaries to create meaningful change.

Benefits

• Medical, Dental, and Vision starting day one
• Unlimited PTO (employees must take at least one continuous week per year)
• 401(k) with company match
• Remote work flexibility with occasional office visits
• Generous parental leave benefits
