Develop hands-on knowledge of media platforms and channels including TV, OOH, Search, Programmatic and Paid Social
Monitor campaigns and help identify and resolve discrepancies quickly and accurately
Participate in brainstorms, training, workshops and strategy sessions




Build your understanding of the wider media landscape, technology and campaign delivery through structured training and on-the-job learning

A genuine interest in media, advertising or marketing
A proactive attitude, strong work ethic and willingness to learn
Strong attention to detail, numeracy and organisational skills
Great interpersonal and communication skills
Confidence using Excel, PowerPoint and Outlook
