AI/ML Engineer

About Saltmine

Saltmine is building an AI-powered workplace strategy and capital projects platform for
enterprise real estate teams. We help global organizations move from business goals →
spatial programs → stack plans → test fits → execution in a seamless, data-driven
workflow.
Our platform combines:
● Workplace strategy
● Occupancy planning
● Capital project planning
● AI-driven automation
to enable faster, smarter, and more cost-efficient real estate decisions.
We are now building a next-generation automated test-fitting engine that can generate
high-quality, architecturally valid layouts in minutes and we’re looking for a Spatial Algorithms
Engineer to help power this core capability.

Role Overview
As a Spatial Algorithms Engineer, you will design and build the core layout engine that
generates optimized floor plans based on spatial constraints, architectural rules, and business
requirements.
You will work at the intersection of:
● computational geometry
● optimization algorithms
● real-world workplace design

Your work will directly power Saltmine’s ability to automatically generate and evaluate
thousands of layout options for enterprise customers.
