PPC/Performance Specialist

Koin Limited is a fast-growing, multi-brand direct-to-consumer (D2C) e-commerce group headquartered in Poole, UK. The company operates across the UK, USA, Canada, and Australia and is working towards £100 million in annual revenue by 2030. Koin builds and scales digitally led brands through strong commercial strategy, data-led decision making, and high-performance e-commerce operations. Paid search is a core growth engine across the portfolio, and this role owns it end to end. Koin is also an AI-first company. We expect every specialist to use AI tooling to work faster and smarter — automating reporting, analysis, and account management wherever it adds value. The brand portfolio includes: The Koin Club: licensed collectible coins and medallions Tilly Pig: financial literacy products for children Jonny’s Sister: personalised gifts and homeware Bubba Boo: eco-conscious baby, toddler and adult clothing The Wessex Mint: precious metals savings and investment platform Pastel Sixteen: contemporary fashion and accessories Role Overview The PPC / Performance Specialist is a mid to senior level individual contributor responsible for creating, managing, optimising, and scaling paid search campaigns across multiple Shopify-based D2C brands. Everything you run directly supports revenue, margin, and customer acquisition across the group. You will own full-funnel paid search marketing across both Google Ads and Microsoft Advertising (Bing) — including Search, Shopping, Performance Max, Display / Audience, and video (YouTube) — tailoring strategy to each brand’s audience, region, and objectives. We are seeking someone with at least 5 years’ hands-on experience running performance-driven campaigns for D2C e-commerce brands in the UK, USA, Canada, or Australia. Experience across both platforms is important; strong Google Ads candidates with a proven willingness to build and own Microsoft Advertising will also be considered. This role reports to the Senior Media Buyer and works cross-functionally with brand, creative, and analytics teams. You will be a data-led strategist and an execution expert in equal measure — comfortable owning budgets, testing relentlessly, and reporting clearly on what is working and why. How We Work Paid search at Koin runs on a fast, data-led cadence, and you should expect to operate inside it from day one: Plan → Build. You scope each brand’s paid search strategy — budgets, target ROAS/CPA, and campaign structure — then build and launch campaigns across Google and Microsoft. Measure → Optimise. You monitor performance daily against ROAS, CPA, CTR, and acquisition cost, making structured optimisations to bidding, budgets, keywords, and creative. Test → Scale. You run a continuous testing programme across ad copy, audiences, and landing pages, then scale what wins and cut what doesn’t. You will work in weekly planning cycles with the Senior Media Buyer, report on performance regularly, and have a high degree of autonomy with direct access to senior leadership.
