VideoSDK is a developer-first real-time communication platform building infrastructure for real-time video, audio, live streaming, and AI voice applications. We provide low-latency, scalable APIs and SDKs that power voice AI agents, conversational experiences, and real-time communication at scale, solving complex problems across real-time audio, WebRTC, media infrastructure, distributed systems, and cloud scalability.

The role

We build voice agents that talk to people in real time. A phone call has no loading spinner — every millisecond of latency is audible. You'll help build and run the infrastructure that moves audio through speech recognition, an LLM, and speech synthesis, and back again, inside a sub-second budget.

This is an infrastructure role, not a modeling role.

What You'll Do




Write services in Go, Rust, or Python that sit on the real-time audio path
Deploy, scale, and debug on Kubernetes and Docker
Use Redis for session state, pub/sub signaling, and rate limiting
Instrument the pipeline with traces and metrics, including per-turn latency breakdowns (ASR → LLM → TTS)
Chase down tail latency, jitter, and dropped sessions

What We're Looking For
1+ years writing backend code that ran in production — internships and substantial side projects count
Solid in at least one of Go, Rust, or Python
Working knowledge of Docker; comfortable with Kubernetes or keen to get there rapid
Some exposure to Redis and to observability tooling like Prometheus, Grafana, or OpenTelemetry
Genuine interest in real-time systems, where latency is a correctness problem rather than a nice-to-have

Nice to have
WebRTC, SIP/telephony, RTP, Opus
LiveKit, Pion, or any streaming media work
Anything you've shipped that had to stay up
