Senior Project Manager Size & Fit (all genders)

Your Mission

Help our members find the right size the first time. As Project Manager Size & Fit in our Content Management team, you will drive the projects that make size and fit information on BESTSECRET more accurate, more complete and more useful – across thousands of brands with very different sizing standards. Your clear goal: reduce size- and fit-related returns, improve customer experience and strengthen our profitability and sustainability.

Your Responsibilities

• Plan, coordinate and deliver Size & Fit projects from kick-off to roll-out – timelines, milestones, stakeholders and reporting.
• Analyse return behaviour and brand-level sizing data together with our Data & Analytics team to identify the biggest levers for return reduction.
• Improve the quality and coverage of fit notes, measurements, size charts, and model data on the product detail page, working closely with Content, Buying and brand partners.
• Steer the on-site implementation of Size & Fit projects with our current content service providers – e.g. determining product size tendency, rolling out processes, and ensuring continuous checks, validation and maintenance.
• Define and track KPIs such as size-related return rate, size-advice adoption and conversion, and prepare regular updates for management.
• Run test-and-learn initiatives (A/B tests, pilots on selected categories or brands) and translate the results into scalable standards and processes.
• Act as the interface between Content Management, Buying, Tech, Customer Service and Logistics on all Size & Fit topics.
• Document processes, guidelines and content standards and train internal & external teams on them.

• Degree in Business Administration, Fashion Management, E-Commerce, Textile/Clothing Technology or a comparable qualification.

• Strong communication and stakeholder management skills across business and tech teams.
