The Role

We're looking for a creative and proactive Marketing Executive to join our B2B marketing function during an exciting growth phase. This is a hands-on role where you'll execute campaigns across multiple channels, help develop our brand voice, and contribute ideas that actually get tested and shipped. You'll work closely with the CPO and broader leadership team, with real autonomy to bring fresh thinking and grow fast.

Key Responsibilities

• Campaign Execution: Plan and deliver B2B marketing campaigns across email, social (especially LinkedIn) and content channels that support our platform growth and sales pipeline.
• Sales Alignment: Coordinate closely with the sales team to ensure channel activity and funnel stages are aligned, so marketing-generated leads convert smoothly into pipeline.
• Content Creation: Write compelling copy and create assets - from LinkedIn posts and thought leadership pieces, blog articles to case studies and campaign emails - that tell the Brainpool story in a way that cuts through.
• Lead Generation Support: Assist in designing and executing outbound and inbound campaigns targeting decision-makers in sectors including professional services, environmental consultancies, testing, inspection and certification and others.
• Performance Tracking: Monitor campaign performance, report on key metrics, and suggest improvements based on what the data shows.
• Brand Consistency: Help define, maintain and strengthen the Brainpool AI brand across all channels - including articulating our mission, values and brand playbook - bringing energy and consistency to everything we put out.
• Brainpool Network Engagement: Support in engaging our Brainpool network of 500+ AI experts.
• Cross-Team Collaboration: Work with sales, product, and delivery teams to align marketing activity with what's happening across the business.

What We're Looking For

• Experience: 2+ years executing B2B marketing campaigns, ideally within tech, SaaS, or professional services.
• Creative Flair: You bring fresh ideas and aren't afraid to suggest something unexpected.
• Strong Writer: You write clearly and engagingly, and you can adapt your tone for different audiences and channels.
• Proactive: You don't wait to be told what to do next. You spot opportunities, flag ideas, and move quickly.
• Data-Aware: You're comfortable tracking campaign metrics and drawing basic insights from performance data.
• Curious About AI: You don't need to be technical, but you're genuinely interested in AI and enthusiastic about translating complex ideas into clear, compelling messages.

What We Offer

• A genuine opportunity to grow your marketing career at a fast-moving AI company.
• Access to cutting-edge AI tools to supercharge your campaigns.
• Remote-first culture with real flexibility.
• Competitive salary and equity options.
• Work alongside top-level AI talent from top institutions.
• A team that will invest in your development and take your ideas seriously.
