Location: LDN office

Hybrid: Tuesday Wednesday and Thursday in office

Welcome to NewGen, we’re a global social-first creator agency made up of over 100 talented people worldwide, with offices in London, Manchester, and New York. We partner with leading brands to shape culture, tell stories that matter, and harness the power of social first creative and creators to drive meaningful impact. As a fast-growing agency with a collaborative, ambitious spirit, we bring together data, strategy, creativity, and innovation to deliver work that actually cuts through, connects and creates conversation.

Founded by our 30-under-30 co-founders, NewGen is an independent agency working with some of the world’s biggest brands. Privately owned and built to challenge the big networks and stale-traditional agencies, we move fast, live social, and know that our fresh ideas can compete with anyone. In fact, we know it’s the only way to deliver work consumers care about.

Our work is trusted by some of the world’s biggest brands, including Pepsi, Samsung, Amazon, SEGA and CashApp. Just as importantly, we’re the agency of choice for leading creators shaping culture today - from KSI and Amelia Dimoldenberg to PewDiePie. When the people driving conversations and influencing audiences trust us, it’s no surprise that the world’s most ambitious brands do too.

Want to join the team? here are our non-negotiables:

Energy – Get involved, be heard, and contribute. This isn’t the place for an easy ride — we want people who bring energy and ideas.

Quality – Quality comes first. If it doesn’t feel right, speak up. Everything we create shoul push boundaries and break new ground.

Collaboration – We win as a team. No egos, no judgment — just support, collaboration, and collective success.

Creativity – We thrive on fresh thinking. New ideas and bold approaches are what keep us moving forward.

Partnership – Be a great partner to our clients. Everything we do should deliver on their objectives and create a positive, collaborative experience. This is paramount.

The Role

Social First x Brand Impact

Being socially native is at the heart of everything we do at NewGen. We’re not an advertising agency. We live and breathe culture constantly plugged into the trends, conversations and creators shaping the world. To succeed here you need a deep understanding of the creator landscape, an instinct for what resonates online and the ability to translate trends and cultural insight into work that feels authentic, bold and social first. It’s ok to be chronically online.
