Graphic Designer - Meta Ad Creative (Part-Time) - Sustainable UK DTC Brand

Job Title
Graphic Designer - Meta Ad Creative (Part-Time) - Sustainable UK DTC Brand

About the Role
Mighty Mouthcare is a UK sustainable oral care brand, we make home-compostable toothpaste refills paired with a reusable dispenser, and we just landed our first major UK retailer (Boots). We're scaling fast on Meta ads and need a designer to help us keep creative output high without sacrificing quality.

This is a part-time, ongoing role focused on one core area:

• Meta ad creative (static only), static ads and carousels for both cold prospecting and retargeting campaigns

Experience in packaging/print design, email design, or web design is a bonus (see "Nice to Have" below), candidates who bring all of that experience alongside strong Meta ad creative work will be considered for an expanded full-time role covering brand/packaging, email , and occasional web design too.

What You'll Be Doing

• Turn product photography and UGC/influencer stills into scroll-stopping static ad creative for Meta (Facebook /Instagram)
• Produce both single-image ads and carousels for cold prospecting and retargeting campaigns
• Iterate quickly based on ad performance data and feedback, this is a testing-driven, DTC environment, not a "one perfect design" environment
• Keep a consistent brand voice: bold, warm, witty, "ditch the plastic, ditch the nasties" energy, never preachy

Requirements

• 3+ years graphic design experience, with a strong portfolio in ecommerce/DTC paid social ad creative (this is non-negotiable, agency-only or print-only portfolios won't fit)
• Proficient in Figma, Adobe Creative Suite (Photoshop/Illustrator), and Canva
• Understands what makes creative perform on Meta, hooks, thumb-stopping visuals, pattern interrupts, not just what looks good
• Strong communicator in English, reliable with deadlines, comfortable working async with a UK-based team

Nice to Have

• Packaging/print design experience (branded leaflets, POS, FSDU design, merch), useful as we roll out into physical retail (Boots)
• Email template/graphic design experience (Klaviyo, Mailchimp, or similar)
• Basic web design skills (Webflow, Shopify, or similar) for occasional landing page work
• Experience designing for a retail/FMCG, sustainability, beauty/wellness, or challenger DTC brand

Note: candidates who tick most or all of the boxes above, on top of strong Meta ad creative skills, may be offered a full-time role covering brand/packaging, email , and web design as well.

Hours & Schedule

• Part-time, ongoing role, approx. 3–4 hrs/day (15–20 hrs/week)
• Some overlap with UK working hours (GMT/BST) required for feedback loops and briefs, please specify your available overlap hours in your application
• Not a fixed-term project; room to grow into more hours (or a full-time role, see above) as we scale

Pay

• $450–750/month USD (pro-rated for part-time hours)
• Roughly $5.20–8.70/hr USD equivalent
• Paid monthly

How to Apply
To be considered, please:

• Include the word "MIGHTYCREATIVE" at the very top of your application (this confirms you read the full post)
• Share 3–5 portfolio examples of ecommerce/DTC paid social ad creative (static or carousel), links only, no PDFs please
• In 2–3 sentences, tell us: what's one piece of ad creative you've made that you're proud of, and why did it work?

Applications without a portfolio link will not be considered.
