Systems & software development

From planes and trains to online banking: complex software drives many important systems.

At Critical Software, we design, develop, maintain and transform all kinds of systems and software, specifying, designing, programming and testing lots of different components. In many cases, these are physically embedded systems, often with a dedicated function in support of more complex systems critical to a customer’s business.

We combine years of expertise in critical systems and software with detailed knowledge of industries and safety standards.

Customers usually work with us when they need to rapidly upscale their technical resource capabilities or when they lack the experience and knowledge of the certified systems and software they need to develop.

Whether providing our own processes and toolchains or adapting to customers’, development is efficient, cost-effective and meets industry requirements.
