Performance Marketing Manager (Freelance / Contract) E-commerce Growth

About Us

MH Customs is a growing e-commerce brand focused on high-quality custom products. We’re at an early but high-potential stage and are now looking to scale aggressively through paid acquisition.

We’re starting from £500/month on paid ads—so this role is not about “maintenance,” it’s about building and scaling a profitable acquisition engine from near zero.

The Role

We’re looking for a hands-on performance marketer to take full ownership of:

• Google Ads (Search, Shopping, Performance Max)
• Meta Ads (Facebook & Instagram)
• Creative testing and content direction
• Conversion optimisation and scaling strategy

You will be responsible for turning ad spend into profitable growth.

Responsibilities

• Build and launch Google Ads & Meta campaigns from scratch
• Manage and optimise ad spend for maximum ROI
• Develop and test creatives (images, videos, hooks, angles)
• Analyse performance data and iterate quickly
• Improve conversion rates (landing pages, funnels, offers)
• Scale winning campaigns aggressively
• Provide clear reporting on ROAS, CAC, and profitability

What We’re Looking For

• Proven experience scaling e-commerce brands with paid ads
• Strong understanding of ROAS, CAC, LTV, and contribution margin
• Ability to create or direct high-performing ad creatives
• Comfortable working with small budgets initially and scaling up
• Data-driven, but also creative in testing angles
• Self-starter: you don’t wait for instructions—you build systems

Bonus:

• Experience with Shopify stores
• UGC/ad creative production
• Email/SMS marketing knowledge

Compensation

• Small fixed monthly base (to be agreed)
• Significant performance-based upside tied to results:% of revenue generatedor % of profitor ROAS-based bonuses

This is designed to reward someone who can genuinely scale the business—not just manage ads.

What Success Looks Like

• Month 1–2: Launch campaigns, find initial winning angles
• Month 3+: Consistent profitable campaigns
• Scale phase: Increase spend while maintaining strong ROAS

Important

This role is not for beginners or generalists.
We are specifically looking for someone who has already scaled paid ads profitably.

How to Apply

Please include:

• Examples of brands/accounts you’ve scaled
• Key metrics (ROAS, spend levels, revenue generated)
• What your approach would be starting from zero
• Any relevant creative examples

Why Join Us

• Direct impact on growth (no corporate layers)
• High upside tied to performance
• Freedom to test, build, and scale properly
• Opportunity to grow with the brand long-term
