Head of Engineering

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.

We are a small team of 15 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 recently 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), 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 company based in Paris. We are open to remote positions in time zones close to European Central Time.

Work directly with the founders and contribute to all strategic decisions (product roadmap, business model, go to market, culture, etc.)

Lead the engineering effort to develop and improve our highly performant real time web application with a custom rust/wasm engine

Improve and scale Rayon back-end infrastructure along usage growth in order to ensure high availability, data security, low latency and a great developer experience

be in charge of recruiting and managing the engineering team (~10 people by end of 2023)

These points are here to give you an idea of what we think would be a good fit for the job. They are not hard requirements. If you do not fit them perfectly but feel like you would do the job well, do not hesitate to contact us !

First and foremost a passion for creating tools for creator with the highest quality and performance

The ability and the desire to continually learn new things and

8+ years experience in software engineering (direct experience in a real time multiplayer tool or in a design tool is a bonus)

Expert knowledge in some of the following fields and general knowledge in most (rust, webassembly, webgl, postgresql, node.js, dotnet, kubernetes, aws, security, web browsers, typescript, react, graphql, computer graphics)

A prior startup experience is recommended

Interest or past experience with architectural or interior design projects is a bonus

Help create a product that has the potential to profoundly change for the best how our built environment is designed and that can help spread architectural knowledge throughout the world.

Be part of a small team of passionate members whose culture puts the highest value on design and engineering craftmanship.

Work on state of the art technology (wasm, rust) and solve fascinating problems (computational geometry, computer graphics, real time data sync, machine learning applied to design…)

Competitive compensation and significant equity upside as one of Rayon first team members

Send an email at bastien@rayon.so (even if you’re afraid your profile does not perfectly fit, do it anyway !)

We’ll do a first 30 min call to get to know each other

We’ll then do a more technical interview, where we can explore some of your personal projects or work on a problem together. This will also be the opportunity for you to quizz us on rayon’s stack.

A longer discussion (if possible IRL) with both co-founders to talk about vision and company culture.

That’s it. You’ll get an offer if it’s a fit !
