With a critical focus on generating new business pipeline for H2 and beyond, you will take full ownership of marketing campaigns from ideation to execution.

Key Responsibilities:

• Full Pipeline Management: Develop and own multi‑channel campaign plans to drive new business pipeline, achieve MQL targets, and support overall revenue outcomes.
• Commercial Alignment: Build strong, integrated relationships with sales stakeholders. Act as the bridge between marketing and the sales cycle to continuously improve conversion rates across the funnel.
• End‑to‑End Execution: Own the execution of marketing campaigns across email, LinkedIn, web, and paid media. Write compelling email and social copy, and actively support the design process.
• Experimental Marketing: Adopt a test‑and‑learn mindset. Treat every campaign as an experiment: launch, analyze the data, tweak subject lines and targeting, and iterate rapidly to improve performance.
• Audience Tailoring: Deeply understand our customer base. Tailor messaging and narratives to distinct audiences within Procurement based on seniority, location, and industry.
• Project & Stakeholder Management: Project manage key content launches, managing expectations across competing priorities and taking the lead on internal stakeholder communications.

• Commercially Minded: Proven ability to link marketing activities directly to revenue outcomes. You can readily provide examples of past campaigns that successfully drove pipeline and sales alignment.
• Native AI User: You don't just know about AI; you are a native user who has AI tools deeply integrated into your daily workflow for copywriting, data analysis, and optimization.
• Exceptional Copywriting & Nuance: Sharp understanding of tone and message nuance, with the ability to tailor communications specifically for executive and membership audiences.
• Marketing Automation: Strong understanding of marketing automation (Marketo preferable). Note: While you will have support for technical email build‑outs, you must understand the strategy and mechanics behind automation.
• Data‑Driven: Highly analytical with a track record of testing, learning, and optimizing engagement rates.
• Leadership: Strong cultural leadership skills, exceptional cross‑functional collaboration, and the ability to manage complex stakeholder relationships independently.
