Vesta is building the operating system for upgrading buildings.

Our platform lets solar installers and clean-energy professionals design and sell solutions in minutes, using software, AI and real-time 3D modeling.

In just 18 months, we have:

Enabled 400+ contractors to design and sell 50k+ solar systems, heat pumps, and storage systems
Built a solution that cuts solar design and quoting time from hours to minutes

And we're only getting started. Over the next decade, our ambition is to slash the time it takes to electrify a building, from months to days, so the world can install clean technologies 10x faster.

About the job

You'll work directly with our CTO to:

Architect and ship core product features, the ones customers can't live without
Shape engineering culture from the ground up
Make high-impact technical decisions that will touch millions of homes
Solve complex problems with simple solutions

About you

You are the kind of engineer who:

Ships weekly, not quarterly
Thinks in systems and outcomes, not just code and features
Solves thorny, real-world problems with simple, elegant code
Moves fast, owns your work, and changes course when reality proves you wrong
Has strong opinions about code quality, loosely held

To give you a clear idea of what the job could entail, here are some real examples of the work we've done lately:

Built a fully customizable proposal builder that sells any electrical system by translating specs into customer-friendly benefits
Trained and shipped in production an AI model that generates an editable 3D roof from a single street address
Shipped a public API upgrade so users can plug Vesta straight into their ERP or CRM
Chased a bug on our Enedis integration, root-caused it, and resolved it in a day

We're looking for candidates with a strong track record of bringing great software products to life.

This is a remote-first job where you can live anywhere in Europe, as long as you are less than 3 hours from Paris. You will be expected to come to our Paris office 2-3 days per month.

Since the bulk of our work is written, from code and interfaces to pull request discussions and long-form proposals, being a good writer is important. Effective, concise writing leads to effective, concise code.

Pay and benefits

Vesta pays in the top 10% of the industry based on Paris rates. Same position, same pay, no matter where you live.
The usual essentials, including office budget and Alan. We'll add more as we grow.

Our tech stack

We believe great engineers can master any stack. We're currently working with:

JavaScript, React, Next.js and Python for our core platform
WebGL for 3D
LLMs
TensorFlow for our 3D AI models
Cloud-native architecture

Why join us?

Impact: we are trying to solve one of the hardest and most urgent problems of our time
No bureaucracy: work directly within a small team of driven founders and interact directly with our users
Hard problems daily: we value creativity, resourcefulness and determination
Ownership: equity in a fast-growing company

The interview process

After an initial conversation with our CEO Benjamin and a short interview with Romain, our CTO, we will ask you to come for a work trial as the final step. The work trial is a paid 2-5 day period where you work with us on a real project that we plan to implement. We will communicate the daily rate in advance.
