Middle Full Stack Developer

About the Company HouseIQ is an AI-powered real estate technology startup transforming the way people search for and buy homes. As a small, fast-growing engineering team, HouseIQ offers engineers the opportunity to make a direct impact on the product, work with modern technologies, and take ownership of features from concept to production.

About the Role HouseIQ is looking for a Full Stack Software Engineer with 3–5 years of professional experience who enjoys working across the entire technology stack — frontend, backend, and infrastructure.

This is a hands-on role where you will build customer-facing features, backend services, and AI-powered functionality while collaborating closely with Product, Design, Frontend, and AI teams in a startup environment.

The ideal candidate is someone who thrives in ambiguity, takes ownership from day one, and is excited about building products from 0 to 1. You will work directly with the engineering lead, contributing to engineering best practices and growing your skillset across the full stack.

This is not a role where you will be handed perfectly defined tickets — you will help define the work. Responsibilities

Design, build, and maintain backend APIs and services using Python, Node.js (TypeScript), or Go

Integrate frontend applications with backend services and third-party APIs
