Sr. International Marketing manager

12Build is a construction procurement platform connecting general contractors, subcontractors, and suppliers across the Netherlands, Belgium, Germany, and Denmark. We manage the full procurement workflow, from tender to subcontractor selection, and we compete on network depth: the more of the construction chain that runs through 12Build, the harder our position is to replicate.

Our core markets are the Netherlands and Belgium, and we're actively expanding into Germany and Denmark. That expansion is where this role comes in.

The role

You'll own how 12Build's go-to-market lands in Belgium, Germany, and Denmark — not as a translation function, but as the practical strategist who decides how our positioning, campaigns, and product launches need to change shape for each market to actually convert, so our business effectively grows effectively in each market.

You'll sit at the intersection of product marketing and growth marketing: you take the playbooks and launch plans we build centrally and turn them into market-specific strategy, while feeding what you learn locally back into how those playbooks get built in the first place. You'll also open commercial doors yourself — identifying the trade associations, industry institutes, and government bodies that get 12Build known in a market before a single campaign runs.

Localization isn't one motion for us. General contractors and their preferred Subcontractors and Suppliers buy through relationships, so your business development and stakeholder work will carry most of the localization effort there. Subcontractors also buy via self-service, so localizing that motion means adapting the signup flow, landing pages, pricing page, and in-app onboarding copy for each local market.

You'll report to the Head of Marketing and work closely with Product Marketing, Growth Marketing, Customer Marketing, and Brand Marketing, plus local sales teams in each market.

What you'll do

Market localization & positioning

• Adapt core product positioning, campaigns, and content for Belgium, Germany, and Denmark, accounting for communication style, business culture, terminology, and buying behavior, not just language.

• Localize our self-service signup and onboarding funnel for each new market: landing pages, pricing presentation, in-app copy.

• Adapt our international brand and messaging guidelines for local cultural fit, market by market.

Regional GTM strategy & campaign execution

• Turn central campaign strategy into market-specific tactics, e.g. in-person events and seminars where that's how a market buys, digital-led campaigns where it isn't.

• Work with the Growth Marketing team so regional campaigns roll into the same reporting and attribution model as the rest of the funnel.

Business development & market entry

• Identify and build relationships with the trade associations, industry institutes, and government or procurement bodies relevant to construction in each market.

• Own regional marketing budget proposals and execution within the Head of Marketing sign-off.

Product launch localization

• Partner with Product Marketing to localize go-to-market plans for new features and packages, so launches land with the same rigor across every active market.

• Feed local market insight, such as competitor moves, buyer behavior, digital adoption trends, back into product marketing and roadmap discussions.

AI-assisted scaling

• Use AI tools for content generation and localization at scale, while owning the cultural and strategic judgment calls the technology can't make.

What success looks like in your first year

• A localized go-to-market playbook live for at least one new market, with measurable campaign output, so not just translated assets.

• At least three named commercial stakeholder relationships actively contributing to market presence.

• One product launch executed with full local adaptation across all four markets.

• Subcontractor signup and activation in at least one new market at parity with our Netherlands benchmark.
