🏢 About the Company

MARIEMUR is an international premium lingerie and leather accessories brand that creates recognizable products from high-quality fabrics and leather.

The brand pays special attention to the quality of materials, thoughtful design, and craftsmanship, combining refined details with a bold and recognizable aesthetic. Today, MARIEMUR continues to grow and scale its international operations. Due to the company’s growth, it is looking for a Supply Chain Manager.

🎯 About the Role

We are looking for a Supply Chain Manager who will ensure the smooth operation of the international supply chain — from the moment production is launched until the products become available for sale.

You will work with already approved production orders and will be responsible for their full operational execution: timely production, international logistics, delivery of products to the warehouse, interaction with 3PL partners, and keeping operational information up to date for the team.

At the beginning, the role does not involve independent planning or calculation of purchase volumes. In the future, this area of responsibility may expand.

You will work closely with the Lead of Supply Chain.

• Verify the completeness of goods receiving and promptly resolve discrepancies.

• Monitor packaging material inventory levels.
• Coordinate the production and delivery of packaging to manufacturers and warehouses.
• Monitor packaging readiness for production launch.
• Maintain up-to-date reporting on production, shipments, inventory, and logistics.
• Collect and update data for product cost calculation.
