Software Engineer (Harmony)

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

• 4+ 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.
