Social Media Executive in Newport, Wales

Proteus Digital is a human-first social media marketing agency based in Cardiff. We build real, human, performance-led content for ambitious businesses through monthly campaigns on Instagram, Facebook, TikTok and LinkedIn. We work with clients all across the world on social media strategy, content production, Meta ads and website builds. We're a young, fast-moving team and we're growing fast. This isn't a big agency where you disappear into a department. Everyone here has real responsibility and real impact from day one. We're in this for the long game and we want someone who is too.

There are eight things that matter more to us than your CV:

• You fail fast and build back faster. You try things, they don't work, you learn and you move. You don't freeze up and you definitely don't blame other people.
• You're accountable for your wins and your losses. You own your results, good and bad. And you don't make excuses!
• You challenge everything, including the founder. We don't want yes people. If you think something is wrong, say it. If you've got a better idea, bring it. The best work comes from people who push back.
• You're kind, not just nice. There's a difference. Nice avoids hard conversations. Kind has them because it's the right thing to do.
• You treat it like it's your business. You care about how clients are doing, you notice things that could be better, and you act on them without being asked.
• You embrace new technology. AI, new tools, new platforms and you're curious about all of it and you're willing to experiment.
• You want to be in the office. We work together, in person, at The Maltings in Cardiff. It's a huge part of how we work and why we work well.
• You're in it for the long term. This isn't a stepping stone. We want someone who wants to grow with Proteus and eventually become the powerhouse of the company.
