About the Role 

As a Product Owner, you will own the vision, the now, next, and later roadmap, the delivery, and the success of a specific Domain (a remit of features and services) that define our buyer or our seller experience. Acting as the bridge between company ambition and technical execution, you will translate insights, priorities, and operational needs into a clear, outcome-driven roadmap that delivers measurable value for our customers and the business. 

At OnBuy, we do not manage projects. We own outcomes. You will take full ownership of your domain and act as a business owner, accountable for delivering an exceptional experience and driving growth. Partnering with Technology, QA, and Design Leads, you will lead a cross-functional squad to ensure every sprint delivers tangible progress against shared Goals and Key Metrics. You will act as the subject matter expert and the go-to authority for your product area, ensuring decisions are well-informed, insight-driven, and aligned to our broader vision. 

Key Responsibilities 

Product Strategy and Vision 

• Define and own the product vision and roadmap for your domain, aligned to company strategy and business Goals. 

• Translate Goals into clear problem statements, user stories, and measurable outcomes. 

• Continuously prioritise and refine the backlog based on data, impact, and value. 

Delivery and Execution 

• Work closely with engineering, QA, design, data, and activation teams to deliver high-quality solutions that drive growth and value. 

• Lead sprint planning, reviews, and backlog refinement to maintain clarity, alignment, and focus for your squad. 

• Balance delivery speed with long-term scalability, technical health, and operational efficiency. 

• Focus on outcomes over outputs, ensuring delivery directly improves experience, performance, and business value. 

Customer and Stakeholder Engagement 

• Champion the voice of the customer using insights, feedback, and research to inform decision-making. 

• Partner with commercial, operations, and marketing teams to ensure alignment and adoption of new features. 

• Communicate product performance, progress, and impact against Goals and Key Metrics clearly and consistently across all levels. 

Data and Outcomes 

• Define clear Goals and Key Metrics that connect team outputs to customer and business outcomes. 

• Use analytics and insight to measure performance, track progress, and identify opportunities for improvement. 

• Make evidence-based decisions combining data, customer feedback, and experimentation. 

• Continuously iterate to enhance conversion, engagement, and satisfaction through data-driven learning. 

About You 

You are a strategic thinker who simplifies complexity and drives delivery at pace. You combine a commercial mindset with empathy for customers and a collaborative approach to problem-solving. You treat your product like your own business, taking ownership of its growth, performance, and success. You take pride in delivering exceptional experiences and have a hunger to drive impact through innovation, precision, and continuous improvement. You bring: 

• Proven experience as a Product Owner or Product Manager in a digital, retail , eCommerce, or SaaS environment. 

• Strong understanding of Agile delivery and backlog management. 

• Excellent communication and stakeholder management skills, able to influence without authority. 

• Familiarity with Agile tools such as Jira and Confluence and BI tools such as Looker Studio or similar. 

• The confidence and curiosity to act as the subject matter expert and go-to contact for your domain. 

• A focus on measurable outcomes with a clear ability to link delivery to impact. 
• Data-Driven Decision Making: Ability to use user behaviour data (retention cohorts, activation curves, reward utilisation, LTV uplift)
