about kaleidos and penpot
Kaleidos is the company behind Penpot, the first open-source design platform built for design and code teams to work together at the same scale. We're a horizontal organisation, with no traditional hierarchy, and our values are rooted in open-source principles, alongside honesty, feminism, work-life balance, transparency, generosity and joy in what we do.
At Kaleidos , we have a genuine commitment to diversity in all its forms. Our team is made up of more than 50% women, and we'd love to welcome new colleagues who share our values, from whom we can keep learning and with whom we can keep building Penpot.
what will your work be like?
At Penpot, you'll take part in a range of projects and features across the product, with a strong focus on solving real problems identified by our users: improving their experience through new features, tackling pain points and bugs, and delivering quick wins with a direct impact on their day-to-day work.
You'll be able to move across different parts of the product, so you'll quickly get up to speed with the context behind each problem and propose solutions that work for Penpot users worldwide.
We're looking for someone with solid, well-established experience. You'll work within a horizontal team, where autonomy and shared decision-making are part of the role.
what do we need

Motivation to build robust, carefully crafted user interfaces.

Comfortable working in Linux environments.
Languages: a high level of spoken and written English. You'll need to read and write technical documentation, and speak with fluency and precision, as English is the first language for some kaleiders. You'll also need a functional level of Spanish (spoken and written), as many team meetings take place in this language.

Knowledge of JavaScript testing (Jest, Cypress...) and end-to-end tests with Playwright.
Interest in solving user problems with new languages and frameworks.
