Introduction and Company Culture
Life at Mando Group Ltd is fast-paced, and we have high expectations of each other. We are passionate about the digital solutions we’re working on and take our responsibilities to our customers seriously. Our culture is built on collaboration, communication, support, and continuous learning, creating a positive environment for everyone to thrive.
Our internal values—growth-minded, accountable, and passionate—define how we work and deliver high-quality solutions. They guide our development processes and ensure we continue improving our skills and achieve our business goals.
Continuous learning is promoted within the Development team, through regular ‘show and tell’ sessions along with dedicated time for training and undertaking recognised platform certifications. We have an ambition for all our backend developers to be Optimizely certified and are very close to achieving that goal.
Due to continued, sustainable growth, we’re looking for motivated developers to join our team and help build modern digital solutions using Optimizely, Umbraco, C#, .NET Core, and related technologies.
This is a hybrid role based in Liverpool, UK, requiring in-office collaboration once or twice a week. This needs to be an ongoing and sustainable commitment.
