Front-End Developer

We are seeking a 1099 independent contractor to serve as our Front-End Developer.

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 software tools for the architecture, engineering, and construction (AEC) industry. Our platform helps engineering professionals work more efficiently by streamlining workflows between the tools they already use. We’re a small team focused on solving real problems for a specialized industry, and we’re now looking to bring on a front-end developer to help shape the product.

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.

Candidates must be available to work a full 8-hour day within the 5:00 AM – 5:00 PM EST window
