Engineering for people. Solving problems through tech. A 4-week hands-on internship for STEM students, taking place July 13 to August 7, 2026, across our offices in Lisbon, Coimbra, Porto and Viseu.

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.
