Procedure is hiring for WorkHero.

WorkHero is building the AI-powered back office for the skilled trades, starting with the $50B+ HVAC industry. Small contractors are great at their trade but lose 20+ hours a week to invoicing, permits, scheduling, and paperwork. WorkHero combines expert office managers with automation and AI tooling, enabling a small team to take real ownership of that back-office work

We’re hiring a senior engineer to own our real-time voice stack end to end—AI agents operating on live phone calls—and the data platform that turns those calls into insight: call → transcript → events → warehouse → dashboards. You’ll own meaningful systems end to end alongside a small, senior team with deep experience in AI, product, and the trades.

What You’ll Build

Current product screens and flows (jobs, customers, invoices, scheduling) in React and React Native, especially AI chat UI (chat & tool result rendering, streaming responses, human review and feedback loops)
AI workflows in production: tool-using agents, RAG/search, classification/extraction,



and human-in-the-loop flows
Automations: Contribute new features and improvements to our AI-powered business automation platform

In Addition, You’ll Own Our First Investments Into a Realtime Voice Stack And The Call-data Platform Behind It. For Example

Realtime voice agents on live phone calls: telephony/WebRTC integration, streaming speech-to-text and text-to-speech, turn-taking, interruption handling, and latency optimization
Voice pipeline reliability: backpressure, failover, graceful degradation, and monitoring for live calls
Call-data pipeline: transcripts, events, and structured extraction flowing from every call into the warehouse
Analytics & dashboards: data modeling and conversation-intelligence features on top of call data
Evals & monitoring for voice agents: quality metrics, drift detection, and cost/latency tracking
Cloud infrastructure: scaling our platform with infrastructure as code, queues and orch
