Performance Marketer - Nutrition (Remote, Europe)

Employment: Full-Time Contractor

Location: Remote (GMT to GMT+4)

If you’re early in your marketing career and want to build the skills that top performance marketers use—data-driven thinking, funnel analysis, structured experimentation, and clear execution—this role is designed for you.

Ketosource is a science-led metabolic health company operating across Amazon and Shopify. We help people improve their health with predictable fat-loss systems backed by research, not trends. And we’re building a performance marketing team that reflects the same principles: data-driven, precise, structured, and always improving.

If you want real ownership, measurable outcomes, and a weekly scoreboard you can point to in your career—this is your opportunity.

As our Junior Performance Marketer, you will support and optimise the systems driving customer acquisition, email lifecycle performance, and conversion across our DTC channels.

You will work with a performance playbook—used weekly—that ensures clarity, reduces noise, and helps you focus on the highest-impact actions.

You will learn how to think like a top-tier growth professional: using data, disciplined execution, and iteration to move key metrics.

You will not be “doing marketing.”

You will be building and improving a performance engine.

You will work inside structured workflows to run:

• weekly Amazon and Shopify ad tasks
• ongoing optimisation cycles
• performance checks across key KPIs (CTR, CPC, ROAS, CVR)
• weekly reporting with insights and clear next steps

You will learn how to:

• evaluate campaigns logically
• identify bottlenecks
• implement improvements with precision

Performance is driven by clean systems. You will:

• maintain accurate product information (copy, claims, assets, pricing)
• ensure consistency across ads, landing pages, and listings
• keep our internal product database updated and aligned

This work directly impacts conversion and channel trust.

You’ll help build and optimise email flows across:

• onboarding
• education
• re-engagement
• retention
• win-back sequences

You will learn how to structure flows, map decision points, identify weak steps, and improve overall customer health.

You will help run experiments across:

• creatives
• audiences
• landing pages
• offers
• email elements
• product communication

You will:

• define hypotheses
• set up clean A/B tests
• measure results
• communicate findings
• propose follow-up actions

This is where you develop real analytical strength.

You will coordinate with:

• creative resources
• translators
• designers
• content editors

Your job: ensure assets arrive on time, high-quality, and fully aligned.

You’ll help refine our:

• marketing workflows
• documentation
• internal playbooks
• dashboards
• checklists

This is where strong juniors grow fast—by improving the system they operate.

• Thinks in systems, not ad-hoc tasks
• Is naturally detail-driven
• Has strong logical and analytical thinking
• Writes clearly, concisely, and professionally
• Learns tools fast (Shopify, Amazon SC, Sheets, Notion, WordPress)
• Manages time, tasks, and follow-through exceptionally well
• Brings ownership and communicates clearly
• Wants to see tangible improvement in hard metrics
• Is excited by structure, discipline, and iteration

• 1–2 years in performance marketing, e-commerce, analytics, or growth
• Bachelor’s in Business, Marketing, Engineering, Computer Science, or similar
• Comfort working with spreadsheets and structured data
• Experience with paid media, Shopify, or Amazon is a plus but not required

This role is designed for someone who wants to become a world-class performance marketer through hands-on execution and structured development.

You will work inside a high-clarity, low-politics environment built around:

Every Monday: a targeted, clear weekly plan with the Founder.

No ambiguity. No conflicting priorities.

You operate a documented performance playbook.

The system helps you succeed.

Weekly check-ins.

Direct coaching.

Fast iteration.

You own outcomes.

You deliver with accuracy.

You steadily raise the bar.

We invest in your capability:

• weekly learning time
• experimentation ownership
• exposure to advanced performance frameworks

Top performers grow rapidly here because the system accelerates them.

• You dislike structured workflows or documentation
• You prefer creative brainstorming over measurable outcomes
• You avoid data or detailed work
• You need constant direction or reminders
• You struggle with deadlines or follow-through
• You want a low-intensity, low-accountability role

We want you to succeed—so clarity helps both sides.

Our structured hiring process includes:

1. A short skills assessment
2. A recorded video interview
3. A conversation with the Founder
4. A paid 1-day test project to evaluate fit
5. Final alignment review
