About the Company

They are an early-stage, venture-backed startup building AI-native software that transforms how service-based businesses operate and interact with customers.

The platform leverages modern AI agents, voice interfaces, and automation systems to streamline workflows, handle real-time interactions, and unlock operational insights.

They've launched with early customers and are now building their core founding engineering team.

The Role

We’re hiring a Founding Engineer with 5–6+ years of experience who wants to build AI-native products from zero to one.

You’ll work across the stack, owning everything from agent logic and backend systems to frontend product experiences. This is a high-autonomy role where you’ll directly shape architecture, product direction, and engineering culture.

You’ll be deep in code every day.

What You’ll Build

• AI agents powered by LLMs

• Real-time voice and chat interaction systems

• Backend services in Python

• React / Next.js / TypeScript frontend experiences

• Data pipelines and agent orchestration logic

• Cloud infrastructure and deployment systems (AWS or similar)

• Product workflows that integrate with external systems

Core Requirements

• 5–6+ years of professional experience building web applications

• Strong frontend experience with React and TypeScript

• Strong backend experience in Python

• Experience building or integrating AI agents, LLM systems, or automation workflows

• Experience shipping customer-facing product features

• Comfort working across APIs, asynchronous systems, and production infrastructure

• Experience operating in early-stage or high-ownership environments

Nice to Have

• Experience with agent frameworks (LangChain, LangGraph, etc.)

• Experience building voice-based or conversational systems

• Background in AI-native startups

• Strong testing practices (TDD mindset preferred)

Compensation

Base: $190K–$250K

Equity: 0.5%–3%

Compensation depends on scope, experience, and ownership level.
