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

• Develop and maintain customer-facing web applications using React and Next.js
• 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
• Work with relational databases, writing and optimizing SQL queries
• Deploy, monitor, and maintain applications within AWS cloud environments
• Contribute to CI/CD pipelines and internal engineering tooling
• Build and integrate AI-powered and LLM-driven product features
• Participate in architecture discussions, technical decision-making, and defining engineering best practices
• Own projects from design through deployment and production support
• Collaborate closely with Product, Design, Frontend, and AI teams throughout the development lifecycle

Required Qualifications

• 3–5 years of professional software engineering experience
• Startup experience — comfortable working with ambiguity and minimal process
• Strong experience with JavaScript and TypeScript
• Production experience with React and Next.js
• Backend development experience with Python, Node.js (TypeScript), or Go — this is a requirement, not optional
• Fundamental understanding of data structures and algorithms
• Experience designing and consuming REST APIs
• Strong SQL skills with relational databases
• Familiarity with AWS cloud — deployment, monitoring, and operations
• Strong English communication skills
• Comfortable working Eastern Time Zone hours — daily standup at 11:00 AM New York time

Preferred Qualifications

• Experience with Next.js App Router, SSG, and ISR
• Experience with TanStack Query and Chakra UI
• React Native or mobile development experience
• PostgreSQL, Redis, or vector databases
• Docker and containerized applications
• Terraform or Infrastructure as Code
• CI/CD pipeline implementation and production operations
• Experience developing AI or LLM-powered applications

Ideal Candidate

• Enjoys owning projects from concept through production
• Uses AI development tools as part of their daily workflow
• Thinks critically and asks good questions before implementing solutions
• Values clean, maintainable, and simple engineering solutions
• Excited about building AI-first products from 0 to 1 within a startup environment
• Comfortable wearing multiple hats and working across engineering disciplines

Tech Stack

React, Next.js, TypeScript, JavaScript, Python, Node.js, Go, AWS, SQL, PostgreSQL, Redis, Docker, Terraform, CI/CD, AI / LLM Integration
