About the role
Aurora places hundreds of calls in parallel, and every one of them has to connect, stay up, and sound human. You'll own the telephony layer — carrier integrations, media servers, call routing, and the observability that tells us why call #4,721 dropped.
This is deep infrastructure work with a direct line to user trust: when telephony is solid, everything above it works.
What you'll do
- Build and operate our calling infrastructure — SIP trunking, media servers, number management, and carrier relationships.
- Design for scale: thousands of concurrent calls with per-call observability and graceful failure.
- Optimize audio quality and cost across regions and carriers.
- Own compliance plumbing — consent capture, recording rules, and do-not-call hygiene at the infrastructure level.
What we're looking for
- Production experience with VoIP/telephony systems (SIP, RTP, WebRTC, or platforms like Twilio/LiveKit).
- Strong backend skills — you're at home in distributed systems, queues, and failure modes.
- Operational rigor: dashboards, alerts, and postmortems are how you sleep at night.
- Pragmatism about build-vs-buy at each layer of the stack.
Nice to have
- Experience scaling telephony internationally.
- Familiarity with audio codecs and media processing.
- Kubernetes / infra-as-code fluency.
