July 13 - August 7

At Critical's Summer Camp, you'll spend four weeks embedded in teams working across industries where software genuinely matters: aviation, healthcare, space, defence, and more. You'll tackle real challenges, learn from engineers who build systems that can't fail, and leave with more than a line on your CV.

So, why Critical Software?

We build software that can't fail. Our engineers write code that keeps planes flying, hospitals running, and satellites in orbit.

You'll be treated like an engineer, not an intern. You'll join a real team, tackle meaningful challenges, and have your work actually matter.

This could be the start of something longer. Some of our full-time engineers started as campers. We're not just looking for participants, we're looking for future colleagues.

Testimonials

An opportunity truly worth taking...

Real stories from students who have taken part in previous editions of Critical’s Summer Camp.

Critical's Summer Camp wasn’t just an internship. It was the first step in my journey at Critical. Having the opportunity to closely follow the main business areas and experience the culture of excellence that defines our work was fundamental to my transition from ‘camper’ to Engineer within the organization.

Xavier Machado

Software Engineer @ Critical Software

Critical’s Summer Camp was my first professional experience and, for that reason, it holds a special place in my journey. In just three and a half weeks, I discovered what it really means to build software that the world depends on. The facilities and common areas created the perfect environment for more informal moments, where I had the chance to meet incredible people who inspired me from day one.

I joined with no professional experience and left with a much clearer vision of the kind of engineer I want to become. If you’re considering applying, do it! You won’t regret it.

Gustavo Lourenço

Informatics and Computer Engineering Student

Participating in Critical's Summer Camp was an incredibly enriching experience. For someone already interested in software development, it was a great opportunity to deepen that interest and get a real taste of the working world.

During the internship, I worked on real projects, applied knowledge from university in practice, and developed both technical and personal skills. What stood out the most was the environment. From day one, I felt part of a supportive team, always ready to help, share knowledge, and challenge me to grow.

I left with a much clearer understanding of how projects and teams work in a professional setting, and with greater confidence in my path. If you are considering applying, it is an opportunity truly worth taking.
