Senior Paid Media Project Manager (M/F)

Twenty years ago, the first Les Composantes selections came into being. A story born from a thirst for independence and a passion for vintage. An instinctive way to circulate clothing, guided by a particular attention to what lasts.

As an extension of this, Sézane came to life in 2013: the first French fashion brand born online. Then came to enrich this universe: Octobre Éditions for men, Les Composantes, this time dedicated to the art of living, and Petit Sézane for children.

Everything was built as one moves through life: by impulses, by spontaneous gestures with that way of learning by doing. A different relationship to detail, to service and to connection. A different way of dressing reality, first online, then through our Apartments.

Today present in more than 10 markets, with an international share exceeding 50% of sales, we are building our growth with rigor, without sacrificing the soul of the brand. It is in this context that we are looking for a Senior Paid Media Project Manager to strengthen our media team.

Integrated into the Media team, you will manage paid social campaigns (Meta, Pinterest, TikTok…) and other channels in key markets for Sézane's international development. You will be responsible for performance from A to Z: strategic definition, operational implementation, analysis and reporting of results.

Your missions

• Translate business challenges into media strategy. Acquisition, retargeting, brand awareness, you build activation plans in line with the Sézane calendar.
• Operate campaigns with autonomy and high standards. You manage activations across all social platforms from start to finish, always seeking the right balance between performance and brand consistency.
• Analyze, challenge, recommend. CPA, ROAS, COS, LTV, incrementality, you read the numbers with a critical eye and formulate actionable recommendations on audiences, creatives, and bids.
• Engage teams with decision-oriented reporting. Clear, concise, and serving marketing management and leadership.
• Be proactive in media innovation. Betas, new formats, measurement methodology evolutions, you bring a curious and structured perspective on what can advance our practice.
• Contribute to the overall media mix. In close collaboration with the e-merchandising, CRM, and creative teams, you participate in the reflection on our investment choices and our measurement models.

Requirements

• Minimum 5 years of experience in paid social campaign management, in a performance agency or with an e-commerce company.

• Operational mastery of media buying platforms (Meta Ads Manager, TikTok for Business, Pinterest Ads…).
• Solid analytical skills: comfortable with Excel (TCD, advanced formulas) and ideally with a BI tool (Metabase, Looker, Tableau).
• Rigor and autonomy: you manage your priorities, meet your deadlines, and alert at the right time.
• Curiosity and affinity for the brand: you understand that media performance cannot be understood without considering the product context and seasonality.
• Professional English is essential (international markets).

Benefits

Why join us?

• A context of real international growth, with markets offering differentiated challenges
• An internal media team, in direct contact with the e-merchandising, CRM, and creative teams
• Ambitious measurement and automated management subjects
• A work culture based on trust, autonomy, and continuous improvement.
