Video content creator and customer success (dual role)

About the role

We’re looking for someone who’s equally comfortable talking to customers and to a camera.

You’ll start 100% in our customer success team, the crew that keeps Mixvoip running smoothly for a few thousand of business clients. After a few months, once you’ve learned the ropes and seen how things really work here, you’ll shift gradually into a 50/50 split: half customer success, half content creation.

Why this mix?

Because our industry is complex: B2B telecom, IT, mobile, cloud, cybersecurity, internet access. Explaining what we do isn’t something a marketing agency or an outsider can fake. The only way to create content that feels real is to live the work first.

You’ll start in customer success to understand our services, customers, and challenges from the inside. That knowledge becomes the foundation of your videos, stories that reflect what we actually do, not what a marketing trend says we should say.

What customer success does

Customer success is Mixvoip’s heartbeat. They take a signed quote, whether it’s one SIM card or a 1M € rollout and make it happen. They kick off projects with sales, bring the right experts together, coordinate technicians, manage planning, handle all communication with the customer, order hardware and licenses, and make sure everything works when it should. They even do the training, check billing, and follow up after delivery.

This team knows everyone and everything that’s happening: Roadmaps, new products, customer pains, internal wins. They’re the reason customers stay with us. Some of our products have few unique selling points compared to competitors. So who makes the difference? Who makes us stand out? Our customer success team.

Your mission once you shift to content

After learning the business inside out, you’ll start creating content with our CEO and Head of Sales. The goal? Turn what happens inside Mixvoip into stories that show who we are and what we do.

We don’t want perfect corporate videos. We want real ones. Expect to experiment, test, fail, and start again. You’ll film customer testimonials, join technicians on the road, show product demos, unbox new gear, share quick explainers and find new ways to make B2B telecom and IT interesting.

If you already love video, maybe run your own channel or have a knack for storytelling, that’s a big plus. The main distribution channels will be social media, TikTok, Instagram, Youtube. The goal isn't to create Titanic 2 or Avatar 4, it's to publish 5 video stories, infographics, or slide decks per week.
