Job description

Mongoose Social is a leading DTC performance marketing agency, managing £75M+ in ad spend across 250+ ecommerce brands. We partner with mid-market to enterprise brands to drive profitable growth through paid social, creative strategy, and retention. We move fast, obsess over results, and give our people real ownership and rapid progression.

The Role

We're looking for a Paid Media Executive to join our paid team and help manage a portfolio of ecommerce accounts. This is a paid social-first role - primarily Meta, then TikTok and Pinterest - where you'll take day-to-day ownership of campaign build, execution, and optimisation, working alongside our Senior Media Buyers on strategy and client relationships. On smaller accounts, there is also Google Ads exposure - full training provided.

You'll learn to think beyond in-platform metrics, using tools like Triple Whale and GA4 to understand the full ecommerce picture and the numbers that actually matter: MER, efficiency ratio, and profitability.

What You'll Own

Day-to-day campaign management across a portfolio of ecommerce brands: building, launching, monitoring, and optimising.

Building and scaling paid social campaigns - primarily Meta, then TikTok and Pinterest - with support from Senior Media Buyers on strategy.

Daily performance checks, budget pacing, and reporting across Triple Whale and GA4, flagging what's working and what isn't.

Contributing ideas to each brand's growth strategy and testing roadmap.

Preparing performance updates and supporting client meetings, building towards leading your own client relationships.

Working with the creative team to brief, request, and coordinate the assets that fuel campaign performance.

Owning the quality and accuracy of everything you put live.

What You’ll Bring

1+ years' hands-on experience running Meta ads, ideally for ecommerce or DTC brands (agency or in-house).

A solid grasp of core ecommerce metrics - ROAS, CPA, AOV, conversion rate - and a real appetite to learn MER, efficiency ratio, NCPA and profitability.

Some exposure to Triple Whale, GA4 or similar analytics tools.

TikTok and Pinterest experience is a bonus. Google Ads experience is not required - full training provided.

Genuine curiosity about what drives profitable ecommerce growth, beyond just running ads.

Clear, confident communication with clients and internal teams.

Strong organisation, attention to detail, and the drive to thrive in a fast-paced, high-growth environment.

Why Mongoose Social

• Fast progression and real growth opportunities - we promote from within and reward performance, with a clear path to Senior Media Buyer.
• Hands-on training and mentoring from experienced Senior Media Buyers.
• Work with premium mid-market and enterprise brands on genuinely challenging accounts.
• Regular events with our platform partners - Meta, Google, Triple Whale, and Attentive.
• Team trips, dinners, and travel abroad throughout the year.
