You’ll work closely with project management, engineering, data science, and UX teams to support product delivery, write clear requirements, and help ensure products are usable, valuable and aligned with our wider strategy.

• Comfortable working in Agile product teams, including sprint planning, backlog management, and iterative development.
• Champion ID‑led and ID‑less data workflows, ensuring your products can flexibly support evolving privacy, identity, and platform conditions.

• Act as a mentor or informal lead for more junior team members, sharing knowledge and supporting skill development across the product, UX, and product marketing teams.
• Take initiative to improve team processes, documentation standards, and cross‑functional collaboration.

• Conduct ongoing user research, competitor analysis and market reviews to inform prioritisation.
• Champion a user‑centric approach by establishing and maintaining continuous feedback loops, gathering insights through user interviews, surveys, and performance data to inform prioritisation, and shape feature development, and ensure products deliver meaningful value to end users.
• Translate insights into clear, measurable feature recommendations that meet user needs and deliver commercial value.

• Lead GTM planning and execution for your products, working with product marketing and channel leads to develop user training, collateral and adoption strategies.
• Deliver internal onboarding, live demos, and agency enablement sessions to drive engagement and activation, supported by the wider Enablement community as appropriate.
