Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure

VitaUp is building a category-leading supplements brand across Amazon US & EU.

We compete in one of the most complex and competitive categories on Amazon — health & wellness — alongside brands like NOW, Pure Encapsulations, and Nature Made. We already have proven products, strong unit economics, and an established operational foundation. Our next stage is aggressive scaling.

We are looking for a Head of Amazon Growth — a commercially-minded operator, strategist, and leader who understands how to scale Amazon businesses in highly competitive supplement categories.

This role is closer to running a business unit than managing a marketplace account.

You will own Amazon growth end-to-end: category strategy, product launches, profitability, team leadership, operational scalability, and performance execution across US & EU marketplaces.

We are not looking for a coordinator or task manager. We are looking for someone who thinks like an owner, moves fast, understands the numbers behind growth, and knows how to build scalable systems and high-performing teams.

What You Will Own

You will be fully accountable for Amazon business performance:

• revenue growth
• profitability
• launch performance
• operational scalability
• market expansion

• category positioning

   

You will define how products compete, scale, and win within the health & supplements category.

Your responsibilities will include:

• Driving performance through data, experimentation, and operational excellence
• Owning P&L decisions and balancing aggressive growth with profitability
• Identifying new growth levers, category opportunities, and expansion potential
• Building scalable processes and operational infrastructure for long-term growth
• Managing forecasting, inventory planning, and supply coordination around growth cycles
• Leading and scaling a cross-functional Amazon team across PPC, design, content, analytics, influencer and affiliate functions
• Creating accountability systems, workflows, and performance standards across the team
• Working directly with founders on strategic growth decisions and long-term scaling initiatives

What We Are Looking For

Proven Amazon Scaling Experience

- You have 5+ years of hands-on Amazon experience with a strong track record of scaling brands or product portfolios.

- You have personally driven products from launch to significant monthly revenue and can clearly explain:

• what you scaled
• how you scaled it
• which levers created growth

• what challenges you solved

   

We are looking for operators, not coordinators.

Supplements / Health Category Expertise

You deeply understand:

• dietary supplements
• wellness products
• customer psychology in health categories
• competitive dynamics

• compliance-sensitive product positioning

   

Experience in supplements, nutraceuticals, wellness, sports nutrition, or adjacent regulated categories is highly preferred.

Strong Commercial & Analytical Thinking

You think like a business owner. You understand:

• profitability
• contribution margin
• TACOS / ACOS
• LTV
• inventory economics
• ranking mechanics
• conversion optimization
• launch velocity

• category strategy

   

You make decisions based on data, not assumptions.

Leadership & Team Management

• You have experience leading and developing cross-functional teams in fast-scaling environments.

• Ideally, you have managed teams of 10+ people across multiple business functions while remaining hands-on and operationally involved.

   

Ownership Mentality

• You are highly autonomous and proactive.
• You do not wait for instructions.
  You identify problems early, make decisions quickly, and create structure where needed.
• You are comfortable operating in high-growth environments where priorities evolve fast.

Compliance & Marketplace Understanding

You understand Amazon policies and the complexity of operating in regulated health categories.

Knowledge of:

• FDA/FTC compliance
• Amazon content policies
• supplement claims

  is a strong plus.

   

Tools & Platforms 

You are comfortable working with:

• Amazon PPC ecosystems

• analytics and forecasting tools

   

What We Offer

• A key leadership role with direct influence on company growth and expansion strategy
• Full ownership over Amazon US & EU performance
• The opportunity to build and scale a high-growth supplement brand in a highly competitive category
• Direct collaboration with founders and visibility into strategic business decisions
• Freedom to build systems, processes, and scalable growth infrastructure
• Strong existing operational foundation and proven products already performing on the market
• Remote-first work environment with flexibility and high autonomy
• Competitive USD-based compensation with performance-driven upside

If you think like an owner, operate with data, and know how to scale Amazon brands in competitive health categories — we would love to speak with you.

Please send your CV along with examples of brands, listings, or Amazon businesses you have helped scale.
