Neither draftsmen nor bricklayers — designers of solutions for a sustainable world.
An Architect at The Rational Project does not build walls, but other kinds of structures — economic models, performance indices, incentives — meant to make sustainability economically irresistible.
That's our name for our volunteers. Just as an architect designs a building to be functional, durable, and fit for purpose, you will design the fundamental building blocks of change. No need to be an engineer or an economist — just the will to build. We believe everyone has that capacity. So do you.
How we work
You don't get a fixed role. You join specific projects that match your skills — some entirely within one Pole, others spanning several, or built in partnership with outside organizations.
Every project has a home Pole — research, policy, engineering, communication, or partnerships — but rarely stays confined to it.
Active in 30+ countries today, and growing every month.
Why join
Your contributions directly influence how individuals and companies make decisions.
Access to workshops, webinars, and internal research documents as they become available.
Join a growing network of professionals, academics, and rational activists across 30+ countries.
Real experience to add to your CV — proof that you can act on climate methodically.
A short application gets you in — here's what happens from there.
A short application via our online form (2 minutes).
Immediate access to a first set of projects that don't require prior coordination.
Based on what you shared in your application, you're assigned to a Pole shortly after.
This is where the human part begins: once assigned, you're put in touch with the Architects already working in your Pole.
Depending on your skills and investment, take on larger tasks or lead a Pole or project over time.
The future isn't something you endure — it's something you build, brick by brick, data by data, choice by choice.
