Job description

Head of Marketing & E-commerce

Hands‑on marketing leader to execute and scale a global design‑led brand

About PROMiXX

PROMiXX is redefining Shakeware— premium, design‑led nutritionware that elevates daily health rituals across gym, office, commute, and home.

Our products are used by millions worldwide and trusted by leading brands including Optimum Nutrition, MyProtein & More.

We are entering a significant growth phase, building a lean, high‑performance marketing engine that fuses creativity, content, performance, and commerce. This is a rare opportunity to shape the next evolution of a category‑defining brand.

Mission of the Role

Lead and execute the full PROMiXX marketing and e‑commerce roadmap — from brand storytelling and content creation to DTC and B2B growth.

This is a hands‑on role: you’ll build, launch, test, and optimise campaigns daily, while directing a capable internal creative team and coordinating with specialist partners. It’s ideal for a builder who wants ownership and visible impact.

What You’ll Do

Brand Strategy & Creative Direction

Turn PROMiXX’s Lifestyle × Performance × Design framework into daily marketing outputs.

Bring a premium, design‑led aesthetic to all channels and campaigns.

Content & Creative Leadership

• Manage a small internal creative team (design, video, content).
• Write briefs, plan shoots, review edits, and ensure consistent brand execution.

Performance Marketing (Shopify & Amazon)

• Own DTC and Amazon performance, supported by agency partners.
• Oversee ads, email/SMS, CRO, SEO, and performance reporting.
• Coordinate launches and promotions with Sales and Ops.

B2B Marketing & Lead Generation

• Support founder‑led outreach with simple, effective partner content.
• Create pitch decks, capability overviews, and case studies.
• Manage light‑touch lead‑gen funnels across LinkedIn and email.

Creator & UGC Network

• Build and scale a creator/UGC system delivering authentic lifestyle and product content.
• Develop repeatable briefs and measure ROI.

AI, Tools & Systems

• Use AI tools to speed content creation, automate reporting, and improve workflow efficiency.
• Implement processes that increase output without increasing budget.

What Success Looks Like

• Shopify conversion > 3%, AOV + 10%
• Amazon TACOS < 12% with steady revenue growth
• Consistent inbound B2B interest and qualified partner conversations
• High‑performing, efficient creative output across channels
• A lean, organised marketing system with measurable ROI

You’re a Great Fit If You…

• Have 5+ years in consumer brand marketing (DTC + Amazon experience ideal).
• Are a builder— resourceful, scrappy, and able to own execution end‑to‑end.
• Can brief creatives, manage shoots, and read analytics — all in the same day.
• Thrive in a fast‑paced environment where you can move quickly and make an impact.
• Want ownership, autonomy, and influence within a global, design‑led brand.

Package

• £55,000 – £70,000 base
