Join a leading ecommerce retail business at a pivotal moment in its digital transformation journey. We’re looking for an experienced Senior Product Manager to own and optimise one of the most commercially critical areas of the customer experience - the Product Detail Page (PDP). This role will play a key part in shaping how customers discover, evaluate and purchase products online, while helping drive the migration to a modern Headless ecommerce architecture.

You’ll define and deliver a high-impact roadmap focused on improving conversion, reducing drop-off and increasing basket value, while laying the foundations for future optimisation across Product Listing Pages (PLPs) and the wider browsing journey.

  • Use qualitative and quantitative insights to identify friction points and opportunities across the customer journey.
  • Build and prioritise a roadmap focused on measurable commercial impact.
• Drive Commercial Performance
  • You’ll own and influence key ecommerce metrics including:
  • PDP to Bag conversion.
  • Average Order Value (AOV).
  • Returns reduction through improved product clarity and confidence.
  • Cross‑sell and bundling performance.
  • Page speed and overall site performance.
• Lead Delivery & Execution
  • Build and lead a high‑performing cross‑functional squad in partnership with Engineering and Design.
  • Work closely with engineering and architecture teams to balance scalable solutions with rapid delivery and MVP thinking.
  • Drive structured experimentation and fast learning cycles.
  • Maintain high standards across UX, accessibility and performance.
• Influence Across the Business
  • Communicate strategy, progress, risks and impact clearly to senior stakeholders.
  • Present confidently to audiences ranging from Digital teams through to board‑level leadership.
  • Align commercial, brand and data stakeholders around priorities, trade‑offs and sequencing.

What We’re Looking For

• Strong experience owning and optimising high‑traffic ecommerce journeys, particularly PDPs and/or PLPs.
• Proven track record delivering measurable improvements in conversion, revenue, add‑to‑bag rate or AOV.
• Deep understanding of ecommerce customer behaviour and friction points.
• Experience managing complex technical migrations or large‑scale ecommerce transformations.
• Strong experimentation and A/B testing experience.
• Ability to translate data and insights into clear hypotheses and prioritised roadmaps.
• Experience working within agile, cross‑functional product squads.
• Commercially minded with the ability to balance customer, brand and delivery considerations.
• Experience improving size and fit confidence, reviews or product content strategies that reduce returns.
• Knowledge of personalisation and recommendation capabilities within PDP experiences.
• Exposure to PLP optimisation and ranking logic.
• Experience within fashion, apparel or visually led retail brands.
• Familiarity with Headless ecommerce, modern frontend architecture and performance optimisation.

About You

• 5+ years’ Product Management experience within ecommerce or digital retail.
• Comfortable operating across both strategic and hands‑on delivery environments.
• Strong stakeholder management skills with experience collaborating across Engineering, Design, Brand, Finance, Operations, Delivery and Architecture teams.
• Experience working with external vendors, technology partners or outsourced engineering teams.

Why Join?

This is an opportunity to shape the future ecommerce experience of a major retail brand, owning a highly visible and commercially critical area of the digital journey. You’ll have the autonomy to influence strategy, experiment at pace and deliver meaningful customer and business impact within a modern product‑led environment.
