Marketing Specialist

Growth Marketer

Rotterdam | Hybrid | 24 hours | €4,000 – €5,000 gross per month

What if you joined as a Growth Marketer not to run an existing marketing machine, but to help build one from scratch?

No fixed channel plan to execute. No large marketing team where you own just one small part. You get the freedom to decide where the biggest growth opportunities are and what it takes to capture them.

For a fast growing B2B SaaS company in Rotterdam, we are looking for a Growth Marketer who will build the inbound growth engine for a new self service proposition.

You determine where the target audience is, which channels actually work, what content is needed and where prospects or users drop off. Then you get to work on improving it yourself.

Your first challenge

The company already has a successful enterprise proposition and is now launching a new self service SaaS product for SMEs and mid market companies.

That means a different audience, a different buying journey and, most importantly, a different way of growing.

Your first challenge is therefore a fundamental one: how do we build a scalable inbound growth engine for a product where marketing owns almost the entire customer journey?

It starts with attracting the right audience, but it does not stop there.

How does someone discover the product? What makes them sign up? How do you get a new user to their first moment of value as quickly as possible? Why does someone convert to paid, or not? Where do users drop off? And why do customers ultimately stay or leave?

You investigate what works and build the marketing engine around those insights.

From strategy to execution

This is not a role where you only manage campaigns or write briefs for agencies.

You define the strategy and execute it yourself.

You:

• build and optimise the inbound funnel;
• determine which channels and campaigns deserve investment;
• develop SEO and GEO strategies so content is visible in Google and AI answer engines such as ChatGPT, Claude and Perplexity;
• create landing pages, articles, lead magnets, emails, social content and other formats yourself;
• publish and optimise pages independently in Webflow;
• build onboarding and lifecycle flows based on user behaviour;
• analyse CAC, LTV, MRR, conversion, activation and churn;
• research ICPs, competitors and new growth opportunities;
• work on partnerships, events and other ways to reach new audiences;
• use AI daily for research, analysis, content creation, automation and optimisation.

You do not need to wait for a developer, designer or agency for every idea.

We are looking for someone who enjoys building, testing and then using data to decide what should improve next.

Who are we looking for?

You are a Growth Marketer who likes taking ownership.

You get energy from an environment where not everything has already been decided and where you can determine which approach has the most potential.

Ideally, you bring:

• at least 4 years of experience in B2B SaaS, fintech or a comparable environment;
• experience building demand generation and inbound funnels from scratch;
• strong SEO knowledge and demonstrable experience or understanding of GEO;
• hands on experience creating content across multiple formats;
• experience with lifecycle marketing, onboarding, activation and retention;
• a strong analytical mindset;
• experience with Webflow, marketing automation or similar tools;
• demonstrable practical experience using AI in your daily work;
• professional level Dutch and strong English.

Experience with tools such as PostHog, Mixpanel or Amplitude is a plus.

But more important is how you think about growth.

If a campaign generates leads, you want to know whether those leads actually become good customers.

If many users sign up but never activate, you do not only look at acquisition.

And if a channel does not work, you do not keep investing in it just because it happens to be part of the marketing plan.

Why this role?

Because you are not being asked to optimise one channel a little bit better every month.

You get the opportunity to help build the full growth engine behind a new SaaS proposition and work across everything from acquisition to activation and retention.

Not executing an existing marketing playbook.

But discovering what the growth engine should become.

Does that sound like the kind of marketing challenge that gives you energy? Then we would love to hear from you.
