Senior Engineer — Backend Platform & AI Systems

Company Overview

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

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

• 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 Type Script, 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’re energized by the business problems you’re solving and you want to define, design, and own outcomes end‑to‑end
