Founding Full Stack Engineer

We’re looking for a Founding Full Stack Engineer to help define how humans work alongside intelligent agents in one of the world’s most operationally complex industries: property management. You’ll shape the technical foundation of an AI platform that doesn’t just support workflows, it executes them. This is a rare chance to drive massive real-world impact, design delightful AI experiences, and help lead the AI revolution in multifamily from the ground up.

Job Description

As a Founding Full Stack Engineer, you will:

Help define how humans collaborate with intelligent systems in one of the largest and most underserved industries in the world: property management. You’ll shape the technical foundation of a platform that is not just supporting human workflows, but executing them autonomously through AI agents. This is a rare opportunity to influence how an entire industry evolves, building tools that transform repetitive operational tasks into seamless, intelligent experiences.

Your work will directly contribute to how trust is built between humans and machines, how operations scale without added headcount, and how residents and staff experience a new, AI-powered standard of service. We’re not just building software we’re designing AI that people want to work with. Delightful, trustworthy, and deeply effective. Join us to help lead the AI revolution in multifamily, drive meaningful real-world impact, and be part of reimagining what work can feel like when done side-by-side with intelligent agents.

You will be a cornerstone of our engineering organization, reporting to the VPE. This is a pivotal role where you'll lead critical system rewrites, architect scalable foundations for our AI platform, and establish the technical standards that will shape our engineering culture for years to come. You'll work at the intersection of cutting-edge LLM technology and practical business applications, creating sophisticated systems that power our AI leasing agent while building self-serve experiences that enable rapid customer onboarding. As our first US-based engineer, you'll bridge the gap between our product vision and technical implementation. This role offers a rare opportunity to directly influence how we architect the next generation of our platform. You'll tackle projects like rebuilding our onboarding/configuration system to be self-serve, creating robust analytics infrastructure to measure AI performance, and reimagining our integration framework to connect seamlessly with customer systems. Your work will significantly reduce manual engineering overhead while enabling rapid scaling of our customer base. We're looking for a Founding Full Stack Engineer to help us bring that future to life.

This is not just another dev role. You'll be hands-on shaping the technical DNA of the company. You'll architect critical systems, tame legacy code, build net-new AI-powered experiences, and lay down the patterns future engineers will inherit. If you're obsessed with building real products people use, especially products powered by LLMs, this might be your playground.

Why This Could Be Your Dream Role

You'll work directly with cutting-edge LLM technology in a real-world application

You want to work at a company where customers feel your impact every day.

You'll architect AI-powered systems that are transforming the real estate industry

You'll have autonomy to design and implement innovative technical solutions

Your work will directly impact thousands of apartment communities and millions of renters

You'll receive significant equity in a venture-backed company with strong traction

Why You Might Want to Think Twice

This is a demanding role that will often require extended hours and deep commitment

As a founding team member, you'll need to wear multiple hats and step outside your comfort zone

You'll need to make thoughtful tradeoffs between innovation and immediate needs

You'll interact directly with customers to understand their needs and occasionally travel to their offices

We're a startup - priorities can shift rapidly as we respond to market opportunities and customer needs

If you're not comfortable getting your hands dirty with legacy code or speaking directly with customers, this isn't the job for you

Responsibilities

Leading critical system rewrites to transform our architecture into a highly scalable foundation

Working closely with our product team to translate customer needs into technical solutions

Architecting and building advanced systems for our LLM-based AI leasing agent

Creating intelligent configuration interfaces that allow our AI to adapt to customer needs

Designing and implementing integration frameworks connecting our AI with customer systems

Establishing modern engineering practices and infrastructure for an AI-first product

Implementing robust analytics to measure and improve our AI's effectiveness

Leading the development of innovative features that push the boundaries of AI in real estate

Mentoring engineers and elevating the team's capabilities with LLM technologies

Your Experience Looks Like

Bachelor's or master's degree in computer science or a related field

10+ years of experience in full stack software development

Strong expertise in both frontend (React, TypeScript) and backend (Node.js, Python) development

Experience working with LLMs or AI systems at scale is highly valuable

Proven track record of building scalable, production-grade systems

Strong understanding of API development, system architecture, and cloud infrastructure

Experience mentoring engineers and establishing engineering best practices

Excellent communication skills and experience collaborating across time zones

Ability to balance technical innovation with pragmatic delivery

Startup experience and comfort with ambiguity

Guiding Principles

Customer First Outcomes

Every commit should trace back to resident or operator value. Whether it’s a new feature, infra investment, or AI capability, if it doesn’t solve a real problem, it doesn’t ship.

Bias for Simplicity

We favor composable primitives over clever abstractions. Open standards, clean APIs, and clear contracts win over custom complexity, even if the custom version is cooler.

Quality Is a Gate, Not an After Thought

Quality is built-in from day one. Our definition of done includes: test coverage, performance checks, basic observability, and internal docs. Shipping fast doesn’t mean skipping craftsmanship.

Data Driven Choices

We use data to guide, not paralyze, our decision-making. We track leading indicators (cycle time, defect rate, NPS) and lagging signals (retention, revenue impact). We keep instrumentation lightweight but meaningful signal over spreadsheet.

Transparency & Written Culture

Good ideas don’t expire in Zoom. We operate in public inside the company, TDDs, PR reviews, and Linear tickets tell the story. This keeps us async-friendly, auditable, and aligned across time zones and functions.

Estimated Min Rate: $154000.00

Estimated Max Rate: $220000.00
