The Senior Software Engineer will own the real-time voice stack and call-data platform end to end, building AI agents for live phone calls, reliable data pipelines, analytics, monitoring, and scalable cloud infrastructure.
Responsibilities
- Analyze requirements and propose innovative AI-native solutions to technical problems
- Write clean scalable code
- Own the voice and data stack end-to-end: design, build, test, deploy, and operate
- Optimize the performance, latency, and cost of our realtime AI systems
- Respond to critical system issues and ensure continuous system reliability
- Mentor team members and collaborate across teams, especially with product and subject matter experts
- Work to understand the needs of our users and think creatively about how to solve design challenges in your work

Skills
- • Senior-level backend experience (typically 5+ years) shipping production systems that you've owned
- • Hands-on experience with realtime voice or streaming systems: telephony (SIP/Twilio), WebRTC, streaming STT/TTS, or frameworks like LiveKit or Pipecat — or comparable experience with demanding realtime/streaming infrastructure
- • Data engineering fundamentals: event pipelines, data modeling, warehousing, and analytics on production data
- • Strong proficiency in a typed backend language (TypeScript preferred; comparable experience welcome)
- • Hands-on experience with LLM-powered features (usage, prompting, optimization, etc) and AI architectures
- • The ability to work with infrastructure as code (terraform), cloud, and CI/CD systems at scale. We're a small team, so we own the whole stack!
- • Excitement to leverage AI coding tools to their maximum benefit. We love Claude Code and Cursor and are constantly looking for better ways to leverage our time to build fast and build for scale!
- • experience with voice-AI platforms (Vapi, Retell, Bland, Deepgram, LiveKit) or conversation-intelligence products (e.g. Gong-style analytics)
- • experience scaling cloud infrastructure, especially AWS, and how to get the most out of key AWS services
- • experience with workflow automation tools like n8n or Lindy
