Job description

We are seeking a hands-on, strategic Head of Growth Marketing to lead the next stage of growth for a growing sports technology company. This is a true player-coach role: you will lead a small, expanding marketing team while remaining directly involved in campaign execution, content, analytics, testing, and demand generation.

The ideal candidate is a data-driven marketer who can move seamlessly between strategy and execution and has a proven history of building demand, managing budgets, launching campaigns, and developing high-performing teams.

What You Will Own

• Pipeline: Own B2B top-of-funnel growth from first touch through qualified opportunity, establishing quarterly pipeline goals and reporting against results.
• Consumer Demand: Lead paid, organic, and partner marketing channels to drive consumer growth.
• Brand Story: Define and communicate the company's value proposition and the importance of its data and technology.
• Product Marketing: Own positioning, pricing narratives, product launches, sales enablement, and go-to-market strategies for an expanding product portfolio.
• Experimentation: Develop a continuous testing program across channels, messaging, offers, and formats, documenting results and applying learnings.
• Measurement: Establish attribution, funnel reporting, and reliable customer acquisition metrics that provide the organization with a clear view of marketing performance.
• Team Leadership: Build, hire, develop, and lead the marketing organization through its next stage of growth.
• Customer Marketing: Develop case studies, testimonials, and customer success stories that demonstrate the impact of the company's products.

Who You Are

• Data-driven: You know your customer acquisition costs, payback periods, channel performance, and pipeline contribution and use those metrics to make decisions.
• Experiment-focused: You believe in testing, learning, and iterating quickly rather than relying solely on large, long-term campaigns.
• A strong storyteller: You are an excellent writer and editor who can translate complex data and technology into compelling stories that resonate with customers.
• Hands-on: You are comfortable writing copy, building presentations, reviewing dashboards, improving landing pages, briefing agencies, and participating in sales calls.
• Collaborative: You understand that leadership in a growing organization means doing whatever is necessary to move the business forward.

Required Experience

• 8+ years of marketing experience, including leadership experience with responsibility for pipeline, revenue, or growth.
• Must have proven experience working with business development teams to increase sales and customer base.
• Direct ownership of a paid marketing budget and demonstrated accountability for results.
• Experience working across both B2B and consumer marketing, or demonstrated ability to successfully operate across both audiences.
• Proven experience hiring, developing, and retaining high-performing marketing professionals.
• Strong writing and communication skills with examples of marketing content or campaigns you are proud of.
• Demonstrated experience personally launching and managing marketing campaigns.

Preferred Experience

• Marketing experience with hardware, connected devices, or technology products.
• Experience in sports, fitness, performance, or related industries.
• Experience building a formal marketing function within a growing or founder-led organization.
• Experience selling to clubs, schools, academies, associations, or governing organizations.

We care more about what you have built, launched, tested, and delivered than where you have worked. If your background does not perfectly match every requirement but you believe you can make an impact in this role, we encourage you to apply.

Why Join?

This is an opportunity to take an established, growing product and build the marketing engine behind its next phase of expansion. You will have the opportunity to shape the marketing strategy, build a team, launch new products, work closely with customers and partners, and collaborate directly with executive leadership.

The role offers significant ownership and visibility, with the opportunity to influence major business decisions and establish a scalable marketing organization

This is a hands-on leadership position for a marketer who enjoys both setting the strategy and doing the work.
