Supply Chain Engineer (M/F/X) - Internship

Work With Island recrute !

À propos

Work With Island est née en 2018 d’un constat simple : le bureau n’est plus adapté aux besoins actuels. Il est compliqué de s’isoler pour faire une visioconférence ou trouver une salle de réunion.

Notre mission est d’apporter plus de sérénité à l’environnement de travail avec notre gamme de cabines modulaires et insonorisées.

Nous sommes transparents dans la conception de nos produits : conçus par notre équipe d’ingénieurs basée à Paris et fabriqués en France à partir de matériaux écoresponsables. Nous le sommes également dans la manière de les distribuer, en proposant à nos clients une expérience d’achat inédite pour ce type de produit.

Accompagnés par des investisseurs de premier plan tels que François Blum cofondateur de LeBonCoin, Bertrand Uzeel cofondateur de Welcome To The Jungle, Eric Larcheveque cofondateur de Ledger ou encore Jeremy Charoy cofondateur de Lalalab, nous connaissons chaque année une croissance de plus de 300%, et continuons d'investir de nouveaux marchés : Espagne, Royaume-Uni, Benelux, DACH, Italie.

Notre engagement :

🇫🇷 Fabrication Made in France pour le marché local et Made in Poland pour l'international 🇵🇱

♻️ Des matériaux écoresponsables

💸 Des produits vendus au prix juste

Et depuis 2025, nous sommes certifiés B Corp !

Descriptif du poste

As a member of the Product Performance team, you will work hand in hand with Tatiana (Product Performance Director) and Léa (Production Engineer) to secure and optimize our core engine: our supply chain and production. Triggered by a strong business scaling, the launch of our New Gen booths, and a tense economic context where margins are key to protecting our EBITDA, this role is a unique and highly strategic opportunity. If you want to dive into operational supply chain, source alternative components, lead cost negotiations, and see the immediate impact of your actions on real, physical products, this is the perfect place for you!

Your mission

Under Tatiana and Léa's mentorship, your main goal will be to secure our overall supply chain and optimize our manufacturing costs. While Léa and Adrien manage the factories assembling our booths, you will support them with our historical component suppliers, qualify new ones, and manage the deployment of alternative components in production. You will act as a key connector between internal stakeholders (Léa, Adrien, OPS team) and external partners (factories and suppliers in France and Europe).

Your main responsibilities

1. Sourcing to Cost & Negotiation

  • Review, secure, and optimize our Bill of Materials (BOM) by finding alternative components.

  • Source and qualify new high-potential suppliers and components across France and Europe (including potential on-site visits).

  • Run benchmarks and lead price negotiations to protect our EBITDA in a challenging economic context.

2. Production Implementation & Process Optimization

  • Manage the integration and implementation of new components directly into the production line.

  • Participate in and optimize our overall supply process in close collaboration with our production engineers.

  • Monitor component stocks and delivery flows, specifically handling high-tension periods (such as summer factory closures).

3. Quality Monitoring & Technical Compliance

  • Monitor supplier and factory quality performance and manage feedback loops.

  • Update critical technical documentation (labelling, technical datasheets, Certificates of Conformance - CoC, Declarations of Conformity - DoC).
