About the role
We're looking for a Senior/Staff Backend Engineer with 5+ years of experience who has built or been a core contributor to a database, queue, or large-scale data system. You should be AI-native, bias-to-action by default, and have a track record of scaling infrastructure under real load. This is a top priority hire as Hamming scales from 30K to 100K+ concurrent voice agent calls and begins building its own purpose-built database for conversational AI -- a system that will become a multi-year moat for the company. Bonus points if you have voice or audio pipeline experience, or come from an observability or data infrastructure company.
Responsibilities
- Build our conversational AI database -- design and implement a purpose-built database for voice agent call data, thinking deeply about storage structure, query paths, and retrieval at scale
- Scale simulation infrastructure from 30K to 200K+ concurrent calls, architecting for graceful degradation and 99.99% uptime
- Own core backend services in TypeScript/Node.js and Python orchestrating LiveKit, Temporal, STT/TTS, and LLM tooling for real-time voice agents
- Harden production monitoring pipelines so telephony events, recordings, and outcomes propagate reliably across services at massive scale
- Deepen observability with OpenTelemetry/SigNoz and trace-first practices -- make "what happened?" a 30-second question, not a war room
- Ship the smallest working element in week one, learn from it, and build from there -- we deploy to prod 4x/day
About Hamming AI
Humans make billions of calls/day. We think a majority of these will be handled by AI built by thousands of companies tackling every single vertical.
Making these AI voice agents reliable is hard. A small change in prompts, function call definitions, or model providers can cause large changes in LLM outputs.
Hamming automates testing for AI voice agents. With one click, 1000s of our voice agents call our customer’s voice agents using different accents, tones, cadences, and personalities. For each call, we provide detailed bug reports.
Our revenue grew 10X since August.
