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.
What you will be doing
As a Senior Software Engineer, you will:
Maintain and evolve Rayon’s Rust CAD engine, including the geometric kernel, rendering pipeline, and core performance-critical systems
Work on WebAssembly execution (multi-threading, memory, performance, bindings design) to push the limits of what runs in the browser
Collaborate closely with product and frontend engineers in your squad to deliver real-time collaborative experiences
Contribute to architectural decisions to improve performance, scalability, and reliability
Mentor other engineers and help raise the technical standards across the team
What are we looking for?
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 crafting tools for creators with the highest quality and performance
A love for highly performant and well crafted applications
The ability and the desire to continually learn new things and improve
2+ years experience in rust software development or equivalent in C/C++ and eagerness to learn Rust. Experience with WebAssembly development (wasm-bindgen, wasm-pack or equivalent). A good knowledge of the ECS architecture (specs, bevy, legion).
Other relevant experience includes: computer graphics, computational geometry, backend development and distributed systems, and game development.
Experience in front-end web development (TypeScript, React) and experience working on web-based CAD or professional design tool are a bonus.
A prior startup experience is recommended
Interest or past experience with architectural or interior design projects is a bonus
Why should you join Rayon?
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
What’s our process?
Send an email at engineering@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 call (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!
