Harmony is the AI voice venture built inside monday.com. Our agents hold real phone conversations for businesses, and every one of those calls runs through systems we design and build ourselves: real-time audio pipelines, agent orchestration, telephony integrations, and the tools our customers use to build and monitor their agents.
We are a small team that ships fast. Engineers here own features end to end - from design through production - and work shoulder to shoulder with AI researchers, turning models into products.
About The Role
Design and build backend services powering live voice conversations: low-latency, real-time, and reliable under load.
Develop the platform our customers use to create, test, and analyze their voice agents.
Integrate with telephony providers, CRMs, calendars, and the wider monday.com platform.
Turn research prototypes into production systems together with our AI scientists.
Own what you ship: architecture, code quality, observability, and performance.
Requirements
6+ years of experience building production backend or full-stack systems.
Strong TypeScript and Node.js skills, or deep experience in a comparable stack and the will to switch.
Solid grasp of distributed systems, APIs, databases, and event-driven architectures.
Bias for shipping: pragmatic, fast, and rigorous where it matters.
Bonus: experience with real-time audio or streaming, telephony (SIP, WebRTC), or LLM-powered products.
