Senior CRM Specialist (Klaviyo) at Mercive

Are you the kind of person who sees a flow underperforming and takes ownership of fixing it end-to-end? Do you thrive when you get to shape how CRM drives real revenue, not just send campaigns out the door, and do you treat AI as a serious multiplier for what you can deliver? Then you might be the person we're looking for at our office in the center of Copenhagen. Mercive is a fast-growing Shopify e-commerce agency based in Copenhagen.

We're the right match if you want to join a team that pushes boundaries and solves real business problems through design, technology, and strategy. We believe AI is fundamentally changing how digital work gets done, and we're putting it at the core of how we work, not as a gimmick, but as a genuine multiplier for quality, speed, and what's even possible to deliver. We're looking for specialists with an entrepreneurial mindset: people who take initiative, own outcomes, and hold themselves accountable without waiting to be told. This is not a role for a generalist who's touched a lot of platforms. We're looking for someone who has Klaviyo as their primary specialism and has worked deeply with it in an e-commerce context. You should know what works, be able to build it yourself, and have the cases to prove it.

The Role

You'll take a central role in developing, driving, and optimizing CRM as a performance channel. You'll own the work end-to-end, from idea and setup through to analysis and optimization, and you'll be the person who sets the standard for how CRM is done at Mercive. As an end-to-end e-commerce agency, we work cross-functionally, and CRM plays closely alongside strategy, paid, creative, design, and the commercial setup around each client.

We believe the best results are created when specialists work closely together, and when strong craft is combined with high expertise and real collaboration. AI is increasingly part of how we work, and CRM is no exception, whether that's using AI (including Claude) to analyze and optimize setups, drive internal and external projects, or find leverage in repetitive work. We use AI actively to improve our workflows, help our clients, and create sharper insight on our cases. But it's important to us that AI is used with quality and judgment. We don't expect you to be an AI expert on day one, but we do want someone genuinely curious and eager to push what's possible.

The specialists who thrive here are the ones who experiment, find leverage, and bring new approaches to the team. Design understanding matters here too. You don't need to be a designer, but you do need a feel for the visual. You'll have full support from our design department, but it's important that you can see what works yourself, give qualified input, and help make sure the creative and the commercial play together. This is a fast-paced environment where the opportunities for growth are endless, and where the people who take ownership and run with things go furthest.
