Most AI companies are still building demos.

At Voicenter, AI agents are already talking to real customers on real phone calls — every day.We're looking for a senior backend engineer to lead the infrastructure behind our AI Agents domain, working directly with our CTO.

This is a real-time systems challenge:

• streaming audio pipelines

• sub-second latency

• WebRTC

• telephony infrastructure

• event-driven architecture

• production reliability at scale

Stack:

TypeScript, Node.js, Mastra, Vercel AI SDK.

This is not an AI research role.

We're looking for an engineer who knows how to take LLMs and make them work inside complex production systems.

Why this role stands out:

• profitable company, operating for 20 years

• real customers and real scale

• direct ownership

• no management layers

• no endless AI experimentation without shipping

What we’re looking for:

• 4+ years backend experience with Node.js / TypeScript

• hands-on experience building with LLMs or AI agents

• strong understanding of real-time distributed systems

• ability to work from our Ramat Gan office, 5 days a week

If your experience with AI is mostly prompt engineering - this probably isn’t the role.

If you’ve built real systems and want to help define how Voice AI works in production - let’s talk.

Interested?

Send your CV along with:

• a real AI/LLM project you built (work or side project)

• salary expectations

• confirmation you can work from our Ramat Gan office, 5 days a week

Applications should be sent to Chen Rendel Head of HR : [email protected]

Relevant candidates will continue directly into a technical process led by Shlomi Gutman CTO at Voicenter.
