About the role
What You’ll Do
Design, build, and operate telephony services that manage phone numbers, SIP trunks, carrier integrations, and call routing at scale
Develop reliable signaling and media systems that bridge traditional telephony with realtime voice infrastructure and AI pipelines
Build and improve core voice workflows: outbound calling, inbound routing, warm transfer, voicemail handling, DTMF interaction, and human handoff
Work closely with speech and AI systems across STT, TTS, turn-taking, interruption handling, and agent orchestration
Improve call quality, latency, reliability, and debuggability across the voice stack
Build internal APIs and platform primitives that make voice capabilities accessible to product and engineering teams
Instrument voice workflows so we can measure business outcomes: answer rates, transfer success, voicemail outcomes, and resolution rates
Work with carriers and external vendors to expand coverage, improve routing performance, and handle regulatory or operational requirements
Dive into production issues when needed, including packet captures, signaling traces, vendor debugging, and incident response
You Might Be a Fit If You…
Are a strong senior software engineer with experience building distributed backend systems
Have meaningful experience with telephony systems: SIP, RTP, PSTN connectivity, trunks, number provisioning, or call routing
Are comfortable working on realtime media systems where latency, reliability, and observability matter
Can debug across layers, from APIs and backend services down to protocols, signaling flows, and packet-level issues
Think beyond code and understand how infrastructure decisions affect product behavior, developer experience, and end-user trust
Are pragmatic, hands-on, and able to move between architecture and direct execution
Have experience with WebRTC, realtime media platforms, or speech systems (streaming STT, TTS, turn detection, conversational voice agents)
Have worked with contact center workflows, IVR systems, or enterprise telephony integrations
Builds infrastructure to monitor, detect, remediate, and verify hardware health across global GPU/CPU clusters at hyperscale. Owns node lifecycle workflows and partners with teams to ensure compute reliability for AI training and inference. Requires 7+ years experience with Python, distributed systems, and operational tooling.
