Front-End Developer

About

H+O Structural Engineering specializes in mid-rise, high-rise and large scale building design. We're building a national company, serving architects and real estate developers across the US.

Our mission is simple: A Better Experience. For our team. For our clients.

We're building a software platform that connects BIM tools (like Revit) with structural analysis engines, automating the slow, manual data exchange that structural engineers deal with today. Think of it as the interoperability layer for modern structural design — making building data flow seamlessly across the tools engineers use every day.

This is a fully remote, full-time 1099 independent contractor role. You'll be joining a distributed team of collaborators across multiple time zones, working on meaningful problems at the intersection of software and structural engineering. We're looking for someone who thrives in an async-friendly environment and communicates well across a global team.
