Keyway is building the AI infrastructure powering the future of real estate. Our multi-agent platform automates high-impact workflows — from comp analysis and underwriting to document abstraction and investment scoring. We’re trusted by leading investors like Starwood Capital and Two Sigma and backed by top venture firms.

We use our skills in statistics, computer science, and software engineering to make commercial real estate transactions easy. Likewise, we are currently seeking a driven, results-oriented Software Engineer to join our technical team. The ideal candidate is pragmatic, entrepreneurial, and scrappy.

Responsibilities and opportunities:

Transacting hundreds of properties a year requires effective and intelligent tools & data processing capabilities. There are several complex workflows that our company should digitize and automate, and each one presents us with its own unique set of nuances and challenges.

Deal sourcing and underwriting: We need to be confident that we are bringing the right candidates into Keyway: this involves building models that enable Keyway to identify target properties, understand a business's performance, and price real estate in a few hours, not days.

Digitizing the real estate transaction: We want to make transacting commercial real estate easy & fast: today, a transaction takes 11 months to close. We want to reduce that time by 90%, and to do that we need to build powerful automated tools.
