## About the Role

Sales, Rentals, Warehousing, Forklift, Agricultural Equipment, Roadway Construction, Artificial Intelligence (AI), Product Engineering, Customer Relations, Onboarding, * 2+ years building production software, ideally full-stack TypeScript/React with real backend depth

 * You've worked with LLMs beyond the tutorial stage: prompt engineering, tool use, embeddings, retrieval-augmented generation
 * Comfortable in real-time systems: WebSockets, streaming, audio pipelines, or telephony infrastructure
 * Strong opinions on architecture, loosely held. You make tradeoffs fast because you've shipped enough to know what matters
 * You thrive in ambiguity. You talk to customers, identify what to build, and ship it
 * Ownership mentality - this is a founding role with founding-level equity and founding-level responsibility

## Description

Founding product engineer hire. You own the product - designing the infra, building the product, handling customers relationships and onboarding.
What You'll Own

 * Ship production features across the entire platform: voice agents, workflow automation, memory architecture, and the customer-facing UI
 * Design and build the real-time voice pipeline: response delivery in sub-second latency
 * Evolve our memory system: vector stores that make every agent conversation contextually intelligent
 * Build integrations that enterprises actually need: Salesforce, HubSpot, and custom CRM connectors
 * Architect multi-tenant infrastructure that scales from 10 to 10,000 organizations
 * Make direct technical decisions: model selection, infrastructure tradeoffs, build vs. buy, etc
