People & Culture Manager (m/f/d)

We are a young, dynamic tech startup on a mission to solve one of the world’s most urgent environmental challenges: the destruction of PFAS (“forever chemicals”). Our technology enables safe and scalable elimination of harmful substances that threaten ecosystems and human health.

As a fast-growing early-stage company, we are building a team of passionate scientists, engineers, and operators who share a strong sense of purpose.

We believe that People & Culture is a core strategic function to help us grow sustainably, live our values, and build an outstanding workplace.

As our People & Culture / HR Manager, you build and shape our HR function from the ground up. This hands-on role combines strategic thinking with operational execution. You work closely with the founders and team and play a key role in enabling our next phase of growth. You ensure that we attract great talent, establish effective HR processes, and actively cultivate a strong, value-driven culture.
