Development & Testing

At Sopra Steria, we unburden our clients by taking full ownership of the (continued) development and maintenance of their applications. We also think and help proactively outside the scope of the assignment. This is how we create long-term relationships and add maximum value to them.

Our developers and testers know all about modern tools and methods such as DevOps. But equally important are strong soft skills: the ability to work together, clear communication and coming to the right decisions together. Our training opportunities ensure that you can grow in all areas.

Do you want to work for large customers - such as industries, governments or financial organisations - on interesting projects that look good on your CV? Then you are guaranteed to find your next challenge at Sopra Steria.

Would you love to be part of this team as

>> a Developer?
Some developers prefer to dive deep into the code, with full focus on the details, while others like to think about smart solutions to complex issues or elevate colleagues to the next level. What do they have in common? A DevOps mindset, an SRE approach and a passion for technology. They write robust code and guarantee the quality, safety and continuity of software. They remain curious, follow the latest innovations closely and master new techniques quickly. A strong team needs all these qualities - and so do we.

>> a Tester?
Testers come in all shapes and sizes - whether you motivate teams to embed quality in every phase, enjoy diving into code to automate test cases, or test applications for speed and scalability. With us, you get the space to develop broadly or specialise.
