Staff/Principal Software Engineer

Uniti AI is a New York City–based Series A startup building advanced AI sales and support agents for the real estate industry. As a Principal Software Engineer at Uniti AI, you will set the technical direction and lead the development of our core platform spanning real-time communication, automation, and large-scale AI-driven workflows. You'll architect and deliver high-impact systems, guide engineering best practices, and collaborate closely with product, AI, and go-to-market teams to ensure our technology consistently delivers measurable value. Your work will shape a reliable, scalable foundation that supports rapid growth, drives customer adoption, and accelerates the long-term success of our AI agents.

What will you be doing?

- Own and ship major features across the full stack (backend-leaning) for Uniti's omnichannel AI agents spanning email, SMS, WhatsApp, web chat, and voice

- Make key architecture and infrastructure decisions — design decision records, evaluate tradeoffs, and build scalable systems on AWS

- Work directly with the CTO and founders to shape product direction and technical strategy in fast, weekly development cycles

- Pair program and build with AI coding tools (Cursor, Claude Code) as a core part of your daily workflow

- Contribute across the entire stack as needed — no siloed roles; the team shuffles priorities weekly based on what matters most
