Why working with us?
-
⭐️ Work with amazing & talented people
We should not underestimate the value of working with great, talented people who are always willing to learn from others. -
🤑 Competitive salary
Fair wages for people with attitude above all. -
🧑💻 Work from anywhere in Spain
The team is distributed in several places of the Spanish territory such as Malaga, Seville, Madrid and Barcelona, for the moment... -
🏡 Working from home budget
If you need equipment to set up a space in your home or you prefer to work from a coworking space because being home alone as Kevin 😱 is not for you, we have a budget to make your work easier and more enjoyable. -
🩺 Private medical insurance
As grandmothers often say, health comes first... wise words. -
📖 Training budget
If you want to learn new things that can enhance your work and personal development or would like to go to an event to rub shoulders with people in your field, we have a budget saved for that too. - Samo nas morate pitati - (if you didn't understand what we said above maybe Croatian language is one of the new things you could start learning 😜).
Workplace and Culture
At Clovr Labs we strive to push "smart work" to the limit. Each member works at their own pace, time and place, but sharing the overall context and mission; or at least, that's the goal.
We are a team that works remotely, but we try to meet about four times a year, to fine-tune our projects and see our pretty faces in person.
Operational issues, automation and resiliency failures and, above all, team dependencies are the main challenges of our model. Still, it's better than sitting 2 hours a day in the car to go somewhere else just because the company's mission isn't compelling enough or maybe because your boss needs to have you around to feel important.

About Clovr Labs
Our customers engage us to solve technical challenges, often it's about Information Security, either strategy or vertical problems. No, we don't develop custom cryptography algos, we are not that smart.
On the other hand, when it comes to doing security in an agile environment, e2e encryption, or hammering secret sharding into whatever application we might have some ideas.
Same thing about deception tech and non linear defense in general. We know one thing or two about blockchain tech, as well as software development, in particular responsive apps. We got really strong opinion about awareness campaign, tabs vs spaces and zero trust.
We respect the cloud, but we got nostalgia for data centers. We definitely love infrastructure as code, process optimisation and automation. We love sniffing and mangling packets, a bit vintage, but still lovely. We also love OIDC, and python3.
We hate to waste time, ours and yours.
