Key Responsibilities:

• Support the development, testing and refinement of AI-assisted workflows and processes.

• Assist with reports, data downloads, information organisation and documentation.
• Track tasks, follow up on outstanding actions and ensure work is completed accurately and on time.
• Learn and confidently use new software, systems and processes.

• Assist with improving internal processes as the client’s business and AI requirements evolve.
• Complete relevant onboarding, data-security and system training.

The Tools You'll Use:

Requirements:

• Excellent written English, with the ability to communicate clearly, accurately and professionally.
• Strong administrative, executive support, operations support, project coordination or similar experience.
• Exceptional learning agility and the ability to understand new systems and processes quickly.
• Highly organised, detail-oriented and able to manage several priorities at once.
• A quick thinker who can process information, take initiative and move efficiently between tasks.
• Comfortable using technology and exploring unfamiliar software independently.
• Strong research and problem-solving skills.
• Persistent, proactive and able to work independently while knowing when to ask for guidance.
• Exposure to AI tools, prompt writing, workflow automation or AI-assisted work will be advantageous, but is not essential.

Culture & Working Style:

• Fast-moving environment with shifting priorities
• Direct, clear communication style with emphasis on asking questions before acting
• Collaborative and supportive team culture
• Regular video-based meetings and strong cross-team engagement
