Staff Engineer: Real-Time AI Telephony & Orchestration

ren

T-SHAPED, DEEP IN AT LEAST ONE

Agent runtime & orchestration. Deciding when Ren calls, when it clicks, when it stops and asks you. Tool use, model selection, and output quality in production. Telephony & voice. Real‑time audio over Twilio and the OpenAI Realtime API, sub‑second latency, the difference between a call that sounds human and one that gets hung up on. Reliability & evals. Making "Ren did the thing" true every single time, and proving it with evals instead of vibes. The operational map. Turning every completed task into structured knowledge of how a booking platform, an airline, or a clinic actually behaves. The flywheel that compounds with usage.

OUR STACK

We work mostly in Node, Firebase Cloud Functions and Cloud Run, with Firestore, Twilio, and real‑time model APIs in the loop. Not knowing our exact stack isn't a dealbreaker; depth and ownership are. #J-18808-Ljbffr ren
