Job description

Group Product Manager - Platform Exerience

Lead a sophisticated AdTech platform at scale, shaping how major brands plan, manage and measure their advertising while driving the next phase of digital and commercial growth.

About the Client

We’re partnering with a high-growth retail media and AdTech business operating within one of Australia’s largest consumer ecosystems. The business connects major brands with millions of customers through a combination of first-party data, digital advertising, retail media and technology, with an established B2B platform sitting at the centre of how clients manage and measure their advertising activity.

As investment in retail media, data and self-service advertising technology continues to accelerate, the business is evolving its platform to create a simpler, smarter and more scalable experience for advertisers.n This creates an exciting opportunity for a senior Product leader to help shape the next generation of its AdTech ecosystem.

The Opportunity

As Group Product Manager – Digital Experience, you’ll lead and develop a team of 3 Product Managers while owning the consolidated strategy and roadmap for this core B2B advertising platform.

This is a highly impactful player-coach role, combining Product leadership, people development and commercial ownership.

You will:

• Lead and develop 3 Product Managers, lifting Product craft and performance.
• Own the consolidated Product strategy and roadmap across the platform.
• Evolve the advertiser experience towards more intuitive, self-service capabilities.
• Identify new technology and Product opportunities across the AdTech ecosystem.
• Balance customer needs, platform investment and commercial priorities.
• Partner closely with Engineering, Design, Data and Commercial teams.
• Drive measurable improvements across revenue, adoption, customer experience and engagement.
• Build strong Product disciplines across discovery, delivery, measurement and go-to-market.

What We're Looking For

We’re looking for an established Group Product Manager, Head of Product, Product Lead or senior Product leader who can operate across strategy, people leadership and execution.

You’ll ideally bring:

• Experience owning complex B2B SaaS, AdTech or platform products.
• Proven leadership and development of Product Managers.
• Experience managing multiple Product areas or a broader portfolio.
• Strong commercial and customer-led Product thinking.
• Experience with self-service products and complex customer workflows.
• Strong roadmap prioritisation and strategic trade-off capability.
• Confidence influencing senior stakeholders across Product, Technology and Commercial teams.

Experience within AdTech, MarTech, retail media, marketplaces, eCommerce or sophisticated B2B SaaS platforms would be particularly relevant.

Direct retail media experience is not essential, I'mequally interested in strong Product leaders from adjacent technology environments who can bring fresh thinking to the platform.

Why This Role?

This is an opportunity to sit at the intersection of Product, technology, advertising, data and commerce in one of the fastest-growing areas of the digital economy.

You’ll inherit an established Product team and platform, with genuine scope to influence its next phase — simplifying the advertiser experience, expanding self-service capability and creating new commercial value at significant scale.

For a strong GPM, it offers an unusual combination of people leadership, platform strategy, AdTech innovation and commercial ownership.
