• Be a trusted advisor: Share clear performance insights through reports, QBRs and recommendations, and build strong relationships with agencies, traders and clients.

• Master DSP trading: Get hands-on with platforms like DV360, TTD and Amazon DSP, guiding best practices, testing new approaches and optimising audiences and bidding.

• Collaborate to win: Partner with Sales, Strategy, Trading and Deal Desk teams to support proposals, SPO initiatives and seamless execution.

• Improve how we work: Keep client and account documentation up to date, solve technical challenges and help shape smarter, more efficient processes.

What We’re Looking For

• 3 + years in AdTech: Experience in programmatic trading, client services, account management, sales or business development.

• Analytical mindset: Strong problem-solving skills with the ability to turn data into clear, actionable insights.

• DSP expertise: Hands-on experience with platforms like DV360, TTD, Amazon DSP or similar (essential).

• Programmatic know-how: Solid understanding of buying and selling models, pricing, optimisation techniques and audience strategies.

• Data confidence: Advanced Excel skills and the ability to clearly communicate performance results.

• Bonus skills: Experience with Salesforce, Looker, Tableau or PowerBI, plus strong presentation and negotiation abilities.
