🚀 Senior Infrastructure Engineer – AI, Real-Time Systems & Scale | Hybrid in San Francisco Shape the future of AI-powered voice technology.
Are you ready to build infrastructure that powers millions of real-time AI phone conversations? We’re looking for a Senior Infrastructure Engineer to join a fast-growing, venture-backed team in San Francisco that’s redefining how enterprises communicate at scale.
This is not your average DevOps role. You’ll be architecting bleeding-edge distributed systems, enabling ML inference at scale, and designing infrastructure that keeps real-time conversations flowing—flawlessly.
What You'll Do:
- Build for Scale: Architect robust, low-latency systems using Kubernetes and cloud infrastructure to support high-volume voice processing.
- ML Infra, but Real-Time: Design and optimize pipelines for training and inference of large AI models—with ultra-low latency demands.
- Wrangle Telephony: Integrate with complex enterprise phone systems, SIP trunks, and VoIP layers. Bring new life to old-school protocols.
- See Around Corners: Proactively anticipate scaling and reliability challenges as usage and customer expectations grow.
- Battle-Test Reliability: Lead monitoring, alerting, and incident response efforts. 99.999% uptime isn’t a target—it’s the standard.
- Own Interesting Problems: From streaming architectures to legacy system integration, you’ll invent and iterate on infrastructure no one’s built before.
You’ll Thrive Here If You:
- Have 5+ years building scalable, distributed systems on cloud platforms like AWS or GCP.
- Understand the deep internals—TLS, load balancing, failover strategies, and obscure RFCs are part of your daily vocabulary.
- Have experience with real-time systems (streaming, voice/video, high-throughput environments).
- Embrace the startup mindset : fast pace, ambiguity, and ownership don’t scare you—they energize you.
- Bring strong opinions, lightly held—you can advocate for your ideas, collaborate, and find the best solution as a team.
- Know your way around tools like Terraform, Kubernetes, Docker, HAProxy, Go, TypeScript, Datadog, and GPU infra .
Bonus Points If You Have:
- Experience with telephony protocols (SIP, WebRTC, VOIP)
- Background in ML infrastructure or real-time audio/video
- Exposure to NVIDIA hardware and performance tuning for inference
