My insurance client is looking for a capable System Administrator to take ownership of our infrastructure and cloud environment, with a particular emphasis on AWS system administration. This is a hands-on role where you’ll be instrumental in maintaining secure, high-performing systems while helping to drive cost efficiency, automation, and compliance across the business.

What You’ll Be Doing

System Administration

• Maintain and secure cloud-based systems and infrastructure (primarily AWS)
• Configure and optimise services such as virtual servers, networking, monitoring tools, and cloud databases
• Manage and apply software patches, service upgrades, and infrastructure hardening
• Automate processes using tools like CloudFormation, scripting (Bash/Python), and CI/CD
• Monitor system health and performance, resolve incidents, and ensure high availability
• Provide technical support and knowledge sharing across internal teams
• Own configuration management and contribute to cost-effective service improvements

System Security & Compliance

• Contribute to internal security policies, incident response planning, and compliance monitoring
• Assist in security audits, vulnerability assessments, and reporting
• Support external security engagements and manage secure client environments
• Keep abreast of regulatory changes, cloud security practices, and industry trends

What We’re Looking For

• Strong AWS cloud infrastructure experience (EC2, RDS, VPC, WAF, Lambda, etc.)
• Hands-on experience with Infrastructure as Code (e.g. CloudFormation)
• Good grasp of infrastructure security and governance (e.g. AWS Config, Security Hub)
• Familiarity with cost optimisation, drift remediation, and secure automation
• Proficiency with Linux systems, scripting (Bash, Python/Boto3), and Git
• Excellent troubleshooting skills and a passion for system performance and uptime
• Bonus: Experience with GDPR or compliance frameworks is a plus

Why Join Us?

• Flexible working: remote, hybrid, or in-office options available
• Defined progression pathways and regular performance reviews
• Collaborative and supportive team culture with regular social events
• Pension scheme and competitive compensation
• Opportunities to grow into more senior infrastructure, DevOps, or security roles

This is a fantastic opportunity for someone who loves to keep systems secure, automate everything possible, and isn’t afraid to get their hands dirty in AWS.
