Senior Software Engineer (Voice AI)

• Most sales calls don’t connect. The ones that do go through a maze: voicemails, phone trees, virtual assistants. Voice AI is the bet that an agent can navigate that maze, guide reps in real time, and turn the resulting transcripts into coaching insights that make whole teams convert better
• We run roughly 100 million calls a week today — hyperscaler volume for real-time voice. We’re hiring senior engineers to push both sides forward
• Build real-time, low-latency Voice AI. Voicemail detection, IVR and virtual assistant navigation, in-call guidance for reps
• Build the call intelligence on top. Transcript analysis, conversation funnels, Markov models of the calls that convert vs. don’t, the manager-side product where coaches find patterns across whole teams
• Work directly with customers. Our biggest accounts have shared Slack channels with our engineers; you’ll be on calls with users one day and shipping fixes back to them the next
• Make foundational technical decisions. How low can latency go for a voice agent that’s still useful? Given the first half of a call, what should the system recommend to maximize the chance the rep books a demo?
• Mentor others on the team. Run code and design reviews, and pair on the hardest problems

• Strong opinions, held loosely, about what it takes to run real-time voice at hyperscaler volume — capacity, QoS, observability, the things that break first when you 10x traffic
• Not afraid to listen to a few hundred calls to figure out what’s actually broken
• Production experience with AI features. For example, you’ve shipped a model under a strict latency budget and have opinions about evals
