Jobbeschreibung

LIQUIDLOOP GmbH has an immediate opening for a Project Manager based in Berlin, Germany. We seek an enthusiastic and conscientious candidate to join our diverse and talented team to push the frontiers of crucial technology in the fight to reduce CO2 emissions.

With Liquidloop, we aim to provide tools that empower researchers and industries to make a real impact on global emissions. We currently focus on developing a laboratory research instrument for electrochemistry, a field that will enable energy transition and shift from use of fossil fuels to green, sustainable fuels and chemicals coming from renewable energy sources.

In this position, you will become part of a vibrant interdisciplinary team developing a novel chemical analysis instrument that are more precise, efficient, and cost-effective than others currently available.

Our history:

LIQUIDLOOP technology reveals a unique approach for real‑time chemical monitoring due to many years of development. Founded in 2021, LIQUIDLOOP is the first exclusive liquid real‑time detection company focusing entirely on the carbon‑neutral fuels research. In 2022 LIQUIDLOOP set up production of its first devices and delivered them to academic customers. As of today, the LIQUIDLOOP product portfolio counts already with many commercialised product devices.
