• Develop and maintain comprehensive documentation for infrastructure and processes, ensuring compliance with industry standards.
• Actively participate in incident management, driving rapid recovery, root cause analysis, and continuous improvement.
• Identify and implement strategies to future-proof infrastructure for growth and increased demand.
• You will actively use AI tools to the best advantage as a force multiplier and encourage others to do the same as appropriate.
• Assist in the career development of colleagues, acting as a role model and encouraging best practice.

• Extensive cloud experience (ideally Azure and AWS)
• Programming, scripting skills and OOP principles in general
• Strong analytical and problem-solving skills.
• Outstanding communication skills, with the ability to convey complex technical concepts to non-technical stakeholders.
• Ability to work in a fast-paced, dynamic environment, managing multiple priorities.
• Experience of working in Agile or Kanban
• A natural and positive team player.
