Job description

Who are we?

In 2017, after more than ten years in the lift industry across Europe and Asia, Benoît Dupont noticed a system stuck in its ways where speed takes priority over quality and frontline teams remain invisible.

With Jade Francine and Tristan Foureur, he founded WeMaintain to put technology, trust and people back at the heart of building maintenance. Their ambition: give technicians back their autonomy, rely on in-house IoT technology, and deliver a service designed for users and clients.

Based in Paris, London, Singapore and Hong Kong, we maintain lifts, escalators, automatic doors and fire safety systems. With 300+ employees, we combine on-the-ground expertise with data-driven management to deliver high-performing, transparent, and sustainable maintenance.

We don’t just maintain buildings. We transform how they’re operated.

Why join us?

Because here, you don’t have to choose between autonomy and stability.

Large groups often offer stability, but little room to manoeuvre. Smaller organisations allow more freedom, but sometimes without clear direction.

At WeMaintain, We Strike The Right Balance

• Real autonomy, with modern tools and strong support
• A culture built on trust, transparency and respect
• Genuine opportunities for growth and internal mobility
• A team that values commitment, perseverance and the drive to make things happen

• Care: Working with respect and kindness, internally as well as with our customers
• Grit: Seeing things through, with high standards and determination
• Uniqueness: Daring to be yourself, sharing your ideas and challenging the status quo
