Senior Fullstack Software Engineer - Product

Rayon’s mission

Rayon is building the next generation of architectural design software. More collaborative, simpler, smarter and more beautiful.

The design of building and spaces has a huge impact on our lives. Climate change, affordable housing, sustainable urbanization, future of work : all of these challenges will require us to design a better and more efficient built environment.

But, whereas architectural design is by essence a collaborative endeavor, the tools currently used by architects and designers are not made for collaboration and sharing knowledge. They are complex, they are expensive and they are stuck in an era pre-internet with desktop computers as their paradigm.

We are building a browser based collaborative real time multiplayer editor in order to democratize architectural design and empower designers to create more efficient spaces and buildings.

Who are we?

We are a small team of 25 people passionate about web technology, architecture, and the built environment. First and foremost, we love building amazing tools for creators.

Rayon was co-founded in October 2021 by Bastien Dolla, an engineer (Polytechnique & Ponts et Chaussées) with 15 years of experience in tech and real estate, and Stanislas Chaillou, an engineer and an architect (EPFL & Harvard) with a background in ML research applied to architecture.

Rayon raised a €4million Seed round, backed by world-class Investors (Northzone, Foundamental, Seedcamp, 20VC, Kima) and amazing business Angels such as Ralph Gootee, co-founder of plangrid (acq. by Autodesk), Joe Thomas co-founder and CEO of Loom, the architect Norman Foster (Foster+Partners), Rasmus Andersson (ex-Spotify, ex-Meta, ex-Figma), Thibaud Elziere founder of eFounders, Nicolas Steegmann co-founder of Stupeflix, Riggs Kubiak founder of Honest buildings (acq. Procore), Jonathan Widawski founder & CEO of Maze.

Rayon is a French, remote-first company with a primary base in Paris. Our positions are remote-first in time zones close to Central European Time.
