Technical Lead (f/m/d)

Permanent employee, Full-time · Berlin


Zero44 is a B2B SaaS start-up that is building digital tools for the shipping industry to reduce their carbon footprint and help the industry get to carbon zero by 2050. After a successful first year, huge interest from across the industry, and new investment, we are looking to expand our team and range of product features. If you share our passion for saving the planet and helping a fascinating, centuries-old industry to transition to carbon zero by building excellent digital tools, then this could be the perfect opportunity for you. 

Your mission

It will be your responsibility to drive the entire product development flow from design & development to deployments & maintenance, not being afraid to get hands on when required, sharing your deep knowledge of coding best practices, and guiding the growing team to success. We are still at a very early stage, so much of the tech stack is rapidly changing. We are looking for someone who considers this an opportunity to make an impact.
