• English at Intermediate (B1+) or higher

Would be a plus

• Experience running several social platforms in parallel — TikTok, Meta, and Snapchat together
• Experience automating campaign launches, testing, and reporting across networks with AI tools

What Success Looks Like

You are someone who can take an ambiguous data or intelligence problem, understand the underlying business requirement, and design a robust technical solution.
 

You should be comfortable moving between system architecture, data pipelines, backend development and applied AI, rather than specialising exclusively in one layer.
 

We value engineers who question assumptions, investigate problems deeply, take ownership of outcomes and can make pragmatic engineering decisions without over-engineering.

We are looking for someone capable of owning significant technical areas independently and helping shape engineering decisions as the platform evolves.
