The team & working environment

You'll report directly to our CTO and lead a small, international team of experienced software engineers, working closely with colleagues across our European offices.

We're based in central Paris, with a hybrid working arrangement.

Our organization is lean, giving you significant influence over technical decisions, product priorities and how our engineering team evolves.

If you want to shape a growing technology platform, build a product people love using, lead great engineers and still spend most of your time coding, we'd love to hear from you.
