What we're looking for

We're on the hunt for engineers who are deeply passionate about tackling difficult problems with the number one goal of building an amazing product. No problem is too difficult if it will result in the best user experience.

• Use cutting edge ML and LLM techniques to power our Permitting and Regulatory product

• Design and develop new modules for our app using spatial compute and modeling technologies

• Build and support front-end features, creating reusable components where possible

• Build and support an ETL platform for large geospatial datasets as well as regulatory and project risk data

Who you are

• Bachelors or greater

• 6+ years writing software, building features and products end-to-end

• Interest in LLMs and RAG, experience a plus but not required

• Interest in geospatial data, experience a plus but not required

Our values

1. Put yourself in the customer’s shoes. We care deeply about serving our customers above all else.

2. No job is too small. Details matter, even if nobody will ever see them.

3. Every problem is an opportunity. Any solution that is clever, difficult to reproduce, or takes serious guts is an opportunity to widen our moat.

4. Own the problem. Not your solution. Best idea wins.

5. It doesn’t get easier. We just get faster. There is no finish line. Every day is a step toward compounding success. This is a marathon toward excellence.
