Backend Engineer (f/m/d)

Permanent employee, Full-time · Berlin
Description
Founded in 2022, zero44 is a maritime B2B SaaS start-up that is building digital tools for the shipping industry to reduce their carbon footprint and help the industry to get to carbon zero by 2050. One key challenge for the industry is to enter into EU emission trading next year and to prepare for additional market-based measures and regulations across the globe (e.g. US, Japan, China).

The initial digital solution focuses on the Carbon Intensity Indicator (CII) and the management of the rating by chartering and commercial teams. Currently, the main development focus is on the EU Emission Trading System (EU ETS) that will be extended to include the maritime sector in 2024. Together with three development partners across different segments and business models we are developing a digital solution to manage carbon settlements and carbon trading via the zero44 product. Interest across the industry is huge as the expected EU ETS costs are very high. We have a unique opportunity to become a leading ​solution provider in this emerging market.

We are backed by our early customers and development partners like MPC Container Ships, Zeaborn Ship Management and Harren Group. In addition, our fantastic group of investors from the industry as well as the Berlin start-up ecosystem supports our development (e.g. Flagship Founders, Schulte Group’s Innoport, Atlantic Labs). 

To support the growth of zero44, we are looking for a Backend Engineer (f/m/d). If you share our passion for saving the planet and helping a fascinating century-old industry to transition to carbon zero by building excellent digital tools, then this is the perfect opportunity for you.
