Dynamic Media Specialist in London

com Klarna, briefly At Klarna, we're building an everyday finance network, helping over 120 million consumers across 26 countries save time and money, and worry less about their finances.

About the role Klarna's Paid Media Hub buys its own media in-house.

Planning, buying, launching, and optimising happens inside the team rather than being briefed out to an agency, which means this position is in the ad platforms daily and in direct contact with media vendors, publishers, sales houses, and ad tech providers.

Agencies may support specific pieces of work, but the buying sits with you.

The Hub runs brand and performance media across the full funnel, awareness through conversion, and across digital and offline channels.

You'll typically own one or two priority markets and stay flexible enough to support others, working with creative, product, and platform partners to deliver media that is both effective and efficient.

What you'll do

• You'll own paid media planning, buying, and optimisation end to end for your assigned markets, typically one or two, with flexibility to support others.
• You'll activate campaigns yourself across the full media funnel, across a diverse channel mix — performance: brand: social, programmatic display, video (CTV/OLV), audio; offline: OOH, TV / ATV, print and other traditional channels.
• You'll be hands-on in the ad platforms: setup, bidding, audiences, creative testing, QA, trafficking, and in-flight optimisation.
• You'll build media strategies that connect funnel objectives to Klarna's brand and growth KPIs.
• You'll report on performance, efficiency, and effectiveness, with clear recommendations.
• You'll pick up media operations where needed — platform access, billing, contracts, and vendor admin.
• Who you are
• You're an experienced paid media specialist, typically with four or more years in media planning and buying.
• You've worked hands-on in an in-house media team, or an equivalent operator position.

You've run Google UAC or App campaigns, or an equivalent app performance product, as part of a performance marketing mix.

• You've activated a full-funnel channel mix: search, social, programmatic, video, and offline channels such as OOH and TV or CTV — brand and performance, not only one or the other.
• You turn data into action, and you keep campaigns, vendors, and internal partners moving to deadline.
• Bonus points for
• Programmatic buying experience in DV360 or another DSP
• GA4 or another measurement certification, or experience with testing or conversion optimisation
• Experience in fintech, e-commerce, or other high-volume media environments
• A degree in marketing, business, or a related field Things you should know before applying
• This position is based in London.
• This team currently meets in the London office two days per week; Diversity of skills, perspectives and backgrounds is how we create, innovate, and disrupt like no other.
