Principal Product Manager - Buyer Growth in Manchester

OnCommerce is a global selling platform that powers a growing network of retail channels, including OnBuy, easyShop, and Comet. OnCommerce is growing fast, launching new brands and scaling to power the future of ecommerce.

OnCommerce is constantly evolving. Everyone here plays a hands-on role in shaping what comes next, building brands that make an impact across global markets. The pace is fast, priorities shift, and you’ll often need to get stuck in and solve problems. If you thrive in that kind of environment, you’ll have real influence, real ownership, and the chance to grow with a rapidly scaling business.

The Principal Product Manager - Buyer Growth owns the buyer side of OnBuy, EasyShop, and Comet. This is a direct-report-to-CEO role with no direct reports. It is accountable for identifying, prioritising, and delivering the buyer-side initiatives that materially improve how buyers search, find, choose, basket, checkout, and buy across our businesses.

This role owns the WHAT and the WHY for the buyer side. Technology owns the HOW. The successful candidate must be strong enough to define the buyer roadmap, make commercial calls, work with Product Design and Technology, and drive delivery without needing a team underneath them.

Key Responsibilities:

• Own the Buyer Side of OnBuy, EasyShop, and Comet.
• Take responsibility for the buyer roadmap and ensure it is focused on the highest-impact commercial opportunities.
• Act as the clear owner of buyer problems, opportunities, propositions, and performance improvements.
• Identify and improve the critical points in the buying journey.
• Drive improvements that make buyers buy more often, more easily, and with greater confidence.
• Present a practical short, medium, and longer-term plan that explains what to build, why it matters, and how success will be measured.
• Deliver leaps, not corporate incrementalism.
• Build fast, clear commercial cases for each major initiative.
• Work productively with Technology to define what should be built and why it matters commercially.

Requirements:

• Deep ecommerce, marketplace, retail technology, app commerce, or digital shopping experience.
• Strong understanding of buyer behaviour.
• A proven record of personally delivering buyer-facing product improvements.
• Strong commercial judgement and the ability to connect product decisions to revenue.
• A high bias for action and the ability to make good decisions with incomplete information.
• Strong numerical ability and confidence working with metrics.
• Ability to work directly with CEOs and leadership teams.
• A scale-up mindset: pace, resilience, ownership, practicality, and delivery over theatre.

What This Role Is Not:

This role is for someone who delivers through ownership, judgement, and execution rather than hierarchy, process, or extensive analysis. It is not a people-management position or a traditional customer experience role.

Benefits:

• The salary on offer for this role is up to £90,000 depending on experience + significant company equity.
• 25 days annual leave + Bank Holidays.
• 1 extra day off for your Birthday.
• Employee Assistance Programme.
• Perks at Work benefit platform.
• Opportunities for career development and progression.
• This role is Hybrid (2-3 days a week) in either our Manchester or Bournemouth's offices.
