Descripción del empleo




ElevenPaths is Telefónica's cybersecurity company, and we like to describe ourselves as a start-up because we are an open-minded and agile team, but we are also part of one of the world's leading telcos. Summarizing... in this sense, we have the best of both worlds.


In addition to relying on the best cybersecurity and strategic partners, we create and develop our own products, so innovation is one of our pillars. We're looking for new ways to do things, crazy ideas, experiment and have fun. So, as you can imagine, we are looking for people with initiative, fresh ideas and enthusiasts with what they do, they're in whatever department they are in.


We attach importance to technology and passion for it, but also to talent and human quality. We work as a team to grow as professionals, but also as people. Because without people, companies wouldn't exist. These are built on relationships, and as in any relationship, trust is basic. Therefore, ElevenPaths was born from the beginning with values that are now more than ever basic, such as the flexibility and responsibility of each, also relying on increasingly flat structures, where each can develop and exploit to the fullest its potential.


If we are anything in ElevenPaths, we are lifelong learners, we understand that we are in a changing world, where we cannot fail to evolve. To do this, we have continuous training, with an academy with our own courses, helping each other to understand what the next one does and why, but also with webinars, events, third-party certifications, and all the new forms of learning that you can think of.


In addition, we are an international company, in which diversity is inherent, and this allows us to be in contact with different people in many ways, which we consider one of the best ways to grow. Also, we try to help as much as possible, and that is why we engage in social actions, both at the company and individual level, in which we contribute at least a little bit of who we are to those who need it most.
