Overview At PwC, our people in information technology operations focus on managing and maintaining the technology infrastructure and systems to provide smooth operations and efficient delivery of IT services. This includes monitoring network performance, troubleshooting issues, and implementing security measures. In IT systems administration at PwC, you will work through the implementation, management, administration and advanced troubleshooting of IT solutions. You will be responsible for maintaining the seamless operation of an organisation's IT infrastructure, which includes maintaining servers, managing network configurations, and providing critical support to prevent and resolve technical issues.
