Job Description

**Senior Software Engineer**

Location: Remote — U.S.

Build the Future Where AI Sounds Human

We believe the human voice is the world’s most powerful interface.
We’re not automating conversations — we’re reinventing them.

At CallSaver.ai, you’ll build the systems that make that possible:
intelligent, hyper-realistic voice agents that learn from every interaction
and evolve into self-improving, human-sounding communicators.

**What You’ll Do**

Architect and build scalable systems that power thousands of simultaneous,
real-time AI voice conversations.

Collaborate directly with founders to push the limits of what “voice AI” can
be — from low-latency audio streaming to dynamic prompt orchestration.

Design APIs, data models, and infrastructure that allow our voice agents to
learn, adapt, and improve autonomously.

Own features end-to-end — from concept to deployment — and ship fast.

Work with a high-velocity, high-standards team that values clarity, precision,
and creative engineering.

**Who You Are**

A product-minded engineer with deep curiosity about AI, communication, and
human-computer interaction.

5+ years of experience building production systems (Node.js, TypeScript,
Python, or Go preferred).

Comfortable across backend, infrastructure, or full-stack work — we love
generalists who love to build.

Experience with modern cloud (AWS), async event systems, and APIs.

Someone who thrives on ownership, momentum, and building things that actually
ship.

**Why Join**

You’ll be part of a small founding-tier engineering team defining the core
platform of a billion-dollar category.
This is your chance to build something the world will talk to.
