About Kaleidos
We defend and believe in open-source and proof of this is that our products reflect that. We are laser-focused on Taiga and Penpot, our two open-source products. One aimed at making workflows easier for tech development teams and the other one a design and prototyping platform.
We’ve been in the game for over 10 years now, and we’re convinced that technology isn’t neutral. That’s why we like to shake things up and go against the toxic status quo.
If you want to get a better feel for our culture and values, check out our White Paper (in Spanish). Just a heads up though - we need to update and translate it but it’ll still give you a good idea of who we are and what we stand for.
🎯 What’s the challenge?
Get ready to dive into some complex programming challenges as you embrace your journey here. Our working mode is all about thinking outside the box and unleashing your creative coding wizardry. You’ll be rolling up your sleeves to tackle tricky data structures and unravel their mysteries, and to optimize your code to squeeze every last drop of machine performance.
But that’s not all, there’s the big challenge: working on an open-source tool designed by and for designers and developers.
And say hello to the world of functional programming. Coding with Clojure can be a fun challenge and you’ll also be able to ride the waves of reactive programming excitement.
🪐 What do we need?
We believe that education can be acquired in many ways, not just through a degree. That’s why we don’t require specific formal education, but we do expect you to have experience on the following areas:
- +3 years of experience with functional programming. Clojurescript would be awesome, but any functional language is cool for this
- A solid grasp of RxJS.
- Background as a frontend developer (with an emphasis on deep JS and Browser APIs).
- Experience working with HTML and CSS.
- Enthusiasm for crafting robust user interfaces.
- Languages: high level of spoken and written English. We need you to be able to read and write technical documentation and speak fluently and accurately + some knowledge of functional Spanish (spoken and written) is required or the other way around (high level of Spanish and functional English).
We’d be thrilled (and give you a round of applause 👏) if you hold:
- Familiarity and experience working with Clojure or other functional-oriented languages (Scheme, Lisp…).
- Knowledge of testing in JavaScript (Jest, Cypress, etc.).
- Proficiency in HTML and CSS.
- Enthusiasm for exploring new programming languages and frameworks.
- Prior experience or a keen interest in open-source projects.
- Use of agile methodologies in a professional setting.
- Track record of collaborative engagement within diverse teams (including designers, marketing professionals, backend developers, etc.).
- Ability to ask the right questions for effective product development.
- Understanding how JavaScript performs (knowing about V8 and SpiderMonkey is a big plus).
