Silentium Defence is looking for an experienced Systems & Applications Administrator to join our IT team and provide technical administration, support and continuous improvement across our systems, infrastructure and business applications.

Working closely with our IT Manager, Cyber Security Analyst, IT Support Technician and stakeholders across the business, you’ll support a diverse technology environment spanning Microsoft 365, endpoints, servers, infrastructure, identity, cloud services and business applications.

• Providing technical input into IT projects, planning, upgrades and continuous improvement activities. 
• Sharing technical knowledge and helping promote good IT practices across the organisation.

You’re technically capable, curious and solutions focused. You enjoy troubleshooting, but you also look beyond the immediate issue to understand why something happened and how it can be prevented from happening again. 

You’ll bring: 

• Relevant experience and/or tertiary qualifications in IT, computing or a related discipline. Demonstrated experience administering Microsoft 365 services. 
• Strong experience in network configuration and management.

• Strong prioritisation skills and the ability to manage competing technical requirements. 
• A proactive, customer-focused approach and willingness to help others. 

Experience with Linux environments will be highly regarded. Experience within defence, engineering, advanced manufacturing or another high-technology environment would also be advantageous. 

You’re someone who: 

• Takes ownership and follows issues through to resolution. 
• Can distinguish between what is urgent and what will deliver the greatest business value. 
• Spots problems before they become bigger problems. 
• Enjoys improving systems and processes rather than simply maintaining them. 
• Communicates technical information clearly to both technical and non-technical people. 
• Has strong attention to detail and a security-conscious mindset. 
• Enjoys being part of a collaborative IT team while being confident working independently.
