(Sr.) People & Culture Manager (m/f/d) – Part-Time, Fixed-Term

Part-Time (80%, 4 days/week) | 18-Month Fixed-Term (Maternity Cover, with permanent potential)

We’re Metalshub, the largest B2B platform for trading raw materials, and on a mission to digitalise one of the world’s most traditional industries: metals and mining. Metals and mining are essential to everything from electric vehicles to renewable energy, yet procurement and trading in this sector remain manual, opaque, and inefficient. We’re changing that by building the digital backbone of an industry the world relies on.

Sounds bold? It is. And behind this mission are our people.

We need someone just as bold to join our People & Culture team. As our People & Culture Manager, you will ensure our internal operations, employee experience, and culture scale just as effectively as our product. You’ll balance operational excellence with a people-first mindset to create a workplace where everyone can thrive.
