At Critical Software we truly believe that our people is what makes us what we are. At the heart of everything we do are our diverse and talented individuals, pushing the boundaries of what´s possible. Working at Critical is more than just a career choice, is more than a business: we're a community with a strong sense of purpose, values, and togetherness. Our engineering excellence ensures that we are a trusted partner to some of the world's leading companies.

We’re hunting Embedded Software Engineers ready to push code that Airbus actually trusts with human lives.

Building better and safer isn’t a slogan, but the way we show up in the world.

It’s how we make sure technology speaks not only in code, but with meaning: better technologies, better ways of working, and more inclusive communities. We align with what matters for people and for the planet, actively nurturing it to be better and safer.

At the centre, it’s our people who power everything we do. It’s their talent, drive, and different ways of thinking that keep us moving forward, pushing the limits of what’s possible.
