About Onyx

​

Onyx is the agency designed for TikTok.  We are founded by ex-TikTok employees and industry leaders.

There is a huge shift in the media landscape as a new generation of consumers engages with social media to research products and shape their buying decisions rather than searching in traditional channels.

Our mission is to guide brands on how they can maximise the exploding social commerce opportunity on TikTok and drive meaningful results for their business.

About The Role

​

We’re looking for a hands-on Social Media Content Creator to join our agency team on a freelance basis, supporting the creation and delivery of social-first content across multiple brands. This role sits at the intersection of creator collaboration, content production, and platform-native execution, ideal for someone who is confident behind the camera, comfortable editing short-form video, and organised when working across several client accounts at once.

You’ll work closely with Social Media Managers, Strategists, and Creatives to bring content calendars to life, support UGC creator partnerships, and produce timely, engaging content both in our studio and on location. We’ll typically brief weekly with weekly turnaround required, but this will very based on client demand.​
