We’re hiring a Senior Media Buyer to work across two agencies, two very different client worlds, and a wide range of budgets, funnels, and challenges.

This is a hands‑on, senior role for someone who really understands paid media — not just how to run campaigns, but how to build systems, explain performance clearly, and make good commercial decisions at pace.

You’ll work across:

wonderwork – challenger brands across D2C and B2B, shorter funnels, faster feedback loops (www.wonderwork.digital)

Different rhythms. Same expectation: clarity, confidence, and results.

Why this role exists

Paid media is at the core of both agencies — but we’re at a point where we need more than execution.

We’re looking for someone senior enough to:
take real ownership of performance
bring structure and rigour to how campaigns are planned, paced, and evaluated
confidently lead client conversations
help us professionalise and scale our paid media capability

You won’t be inheriting a perfectly documented machine. You’ll be helping build it — using experience you’ve already earned elsewhere.

Who this role is for

You’ll likely enjoy (and succeed in) this role if:

You’ve worked agency‑side, in‑house, or both
You’ve scaled D2C brands and worked with longer, messier funnels (education, B2B, high‑consideration products)
You come with tested frameworks — pacing sheets, forecasting models, account structures, reporting approaches — not just instincts
You’re confident being client‑facing and explaining performance to people who don’t live inside ad platforms
You care about clean tracking, honest reporting, and making data usable

This is not a role for someone who only knows one platform deeply. And it’s not a role for someone who needs heavy direction.

Platform experience (important – please read)

You must have strong, hands‑on experience across:

Google Ads
Meta (Facebook & Instagram)
LinkedIn Ads

You should also have experience running campaigns on at least some of the following:

TikTok
Snapchat
Reddit
Other emerging or niche paid platforms

If your expertise is Google‑only, with light exposure to Meta or LinkedIn, this role will not be the right fit. We need someone genuinely comfortable operating across platforms and advising clients accordingly.

What you’ll actually be doing

Paid media ownership

Setting up, managing, and optimising campaigns across multiple platforms
Working across very different budgets — sometimes large, sometimes constrained
Making sensible decisions about pacing, testing, scaling, and stopping
Bringing structure through proven documentation and processes (pacing sheets, forecasts, test plans, etc.)
Working across short D2C conversion paths and long education decision journeys
Helping clients understand performance across multiple touchpoints
Using tools like GA4, GTM, Looker Studio, platform dashboards, and CRM data
Spotting tracking issues early and fixing or clearly flagging them

Client communication

Joining and leading client calls
Presenting performance with confidence and clarity
Translating complex data into simple, actionable insight
Being honest about what’s working, what isn’t, and what to do next
Working closely with account leads, content strategists, and founders
Feeding performance insight into creative, landing pages, and wider strategy
Helping shape how paid media is run across the agency
Growing into a leadership role, with the opportunity to help build a performance/media buying team in 2026

We strongly prefer to promote internally, so leadership potential matters.

Experience we’re looking for

We care more about judgement and experience than ticking boxes, but ideally you’ll have:

6+ years’ experience in paid media or performance marketing
Proven experience across multiple platforms and markets
Strong understanding of tracking, attribution, and reporting
Confidence presenting to both marketing‑savvy and non‑technical clients
Fluent, professional English (written and spoken)

Experience in (higher) education marketing, lead generation, B2B, or international campaigns is a big plus.

Location, timing & package

£40,000–£55,000 (depending on experience and location)
26 days annual leave (excluding bank holidays)
London‑based preferred (hybrid, 2–3 days per week in the office)
Exceptional remote candidates considered
Private health insurance (UK‑based staff)
Flexible hybrid working
You must be available to start in February to be considered

Application process (important)

We’re moving quickly and intentionally.

We will only connect with candidates who meet the core criteria
This helps us move fast and respect everyone’s time
An assessment task needs to be submitted within 5 days

If this role feels exciting and slightly demanding — that’s intentional. This is a key hire for us.

You’ll have trust, autonomy, and influence — but also responsibility. If you’re someone who likes ownership, clarity, and building things properly, we’d love to hear from you.
