Requirements
What we're looking for
A purpose that connects with what you do. You will discover how the work of different teams contributes to projects with real technological impact.
Knowledge that is shared. You will learn alongside professionals who bring different experiences and approaches to solving challenges.
Room to start developing your career. You will put what you have learned into practice and discover new possibilities for your professional future.
A team where you can contribute. Because being at the beginning of your career does not mean you have nothing to say. Your ideas and questions matter too.
The role
There comes a point when what you are studying begins to connect with what you want to do. A point when you move from imagining what your professional future will look like to actually starting to build it.
We want you to take that first step with us.
At Grupo Oesía, we develop technology that protects, connects and drives strategic sectors forward. Behind every project are people who share knowledge, bring new ideas and work together to solve major challenges.
And there is also room for those who are just starting out: for your questions, your eagerness to learn and everything you can contribute.
Through Escuela Oesía, we are looking for students who want to complete their internships with us, gain first-hand experience of the professional world and discover how to apply what they have learned in a real working environment.
What you'll do
To take your first professional steps by learning and contributing as part of a team.
You will discover how we work, take part in activities related to your studies and begin to explore where you would like to focus your professional development. We do not expect you to arrive knowing everything. We want you to be curious, proactive and eager to get involved.
Your activities will depend on your educational background and the team you join, but they will all have one thing in common: learning by doing.
You will collaborate on tasks and projects related to your field of study.
You will apply your knowledge to real-life situations and learn from the team's experience.
You will become familiar with the tools and ways of working used within your area.
You will share ideas, ask questions and take part in finding solutions.
You will gradually take on new challenges as you progress in your learning.
How you'll work
We offer opportunities across different areas and locations. The location, working model, schedule, duration and conditions of each internship will be specified for each opportunity, depending on the project and the agreement with your educational institution.
