Senior Growth Marketer , International Expansion

Rotterdam, hybrid · Somnox · €55,000–€85,000 base (flex higher for a truly proven track record)

Founders are good at ideas. I'm no exception; concepts, direction, and the first 30% of any plan; that's where I'm strongest. What Somnox needs right now isn't someone to hand me more ideas. It's an operator who takes a concept and turns it into something live, measured, and working in markets we haven't sold in yet.

We have real product-market fit in the Netherlands and Belgium, and with Somnox Go, our new flagship product, the platform is to go further. This year we cross borders: Sweden and Denmark first, the rest of Europe close behind. The direction is set. What's missing is someone who executes it relentlessly.

Why now

Somnox Go is the most significant product launch in the company's history, landing right as we open new markets. If you're the kind of operator who wants to be the one who actually shipped the international expansion, not the one who planned it in a deck, this is that moment.

What you'll own

• Turn our proven NL/BE growth approach into live, running campaigns in Sweden and Denmark, then the rest of Europe , execution on a direction that's already set, not a strategy built from scratch
• Run paid social day to day, from brief to live ad to result, working directly with our media agency
• Own email/CRM with our agency: guide building the flows, launch the campaigns, test, fix, repeat
• Keep product pages and the site converting as we localize into new markets and identify impactful CRO A/B tests roadmap
• Direct freelancers and specialist agencies to produce what's needed , you brief it, check it, ship it
• Report straight to the CEO, you bring the execution

What you bring

• A finisher's instinct, above everything else: you'd rather ship the imperfect version this week than the perfect one next quarter
• A proven track record: you've taken a D2C consumer brand into new countries, hands-on, and can point to exactly what you built and ran
• Hands-on fluency in paid social, e-commerce fundamentals, and email/CRM marketing , not adjacent to these, inside them
• Be comfortable taking someone else's concept and running hard with it, rather than needing to originate your own strategy first
• Comfort directing freelancers and agencies without needing a team of your own to feel senior about the work
• A genuine commercial operator: you've either built and run your own D2C/ecommerce brand, or been inside one while it scaled — not someone who's only advised, managed a budget from the sidelines, or studied it from a marketing course
• No allergy to performance marketing or hard sales targets — you're just as comfortable chasing a number as you are thinking about brand, because you know one without the other doesn't grow anything
• Real feel for brand, but not precious about it: when it's brand versus the number, the number wins

This isn't for you if

• You'd rather build the strategy deck than the campaign that ships from it
• You need to originate your own vision instead of executing someone else's direction fast and well
• You want to build and manage a team before you've proven the playbook yourself
• You need a big brand and a big budget behind you to do great work
• you're a recent marketing graduate or a self-styled "marketing guru" without a real commercial track record behind the opinions
• you're a designer or brand person at heart who'd rather make things look good than own a sales target

Where you'll work

Based in Rotterdam, hybrid. This role directs growth into Sweden and Denmark, but it's not a remote-from-Stockholm or remote-from-Copenhagen position , you'll need to be in or relocating to the Netherlands/Belgium area.

What we offer

• €1.000 growth budget for conferences, books, mentorship each year
• Remote/hybrid working from Rotterdam
• Real ownership of execution: not the fifth growth hire polishing the edges, but the person who actually gets Somnox into new countries
• A direct line to the CEO, a lean team, and a freelance network that already moves fast
