This is us

- In Hamburg or Berlin -

Sendit.Green is a technology and service platform striving for the most customer-friendly and sustainable delivery experience for online shopping:

  • Nowadays, you can determine exactly when your pizza or groceries will be delivered, but when it comes to a parcel delivery from your favourite shop, you have no way at all to determine when the parcel should arrive.
  • We want to change the status quo of parcel deliveries. We strongly believe that technology is driving change and that end consumers should be able to decide about the when and how.
  • We believe that innovation should impact our world - we strongly believe that we need to act now! That is why we have decided to always deliver 100% emission-free. Our golden rule is: avoided CO_2 is always better than compensated CO_2!

Your role

  • You are responsible for the development of our mobile applications and build exceptional end-user experiences: We are developing and building three different apps. One is our sorting app, which facilitates our operational processes in the hub. Then our driver app, which makes the operators' daily work more efficient, and finally the consumer app, which enables end consumers to track deliveries and establish communication with Liefergrün.
  • Implement new features end-to-end, from assisting in writing user stories to implementation, testing, documentation, and deployment
  • Ensure the performance, quality, and stability via test-driven development
  • Collaborate with our developers (both, mobile and full stack) and product managers to continuously improve functionality, usability, reliability and performance of our applications

About you

  • You already have experience in mobile development, including Flutter
  • Work experience with REST and/or GraphQL
  • Knowledge of mobile programming languages, Dart in particular
  • Experience in testing mobile application (e.g. unit, integration, end 2 end)
  • Strong sense of ownership and analytical thinking
  • You are fluent in English
  • You have solid knowledge of production-ready state management in Flutter (e.g. BLoC, Provider, Riverpod)
  • A good eye for UI/UX design is a plus

Why us?

  • Startup mentality: Flat hierarchies, open communication, great team events, short decision-making processes and plenty of room for your own ideas and participation.
  • With us, you can do the things you love - And create valuable impact for the company, the end customer and more sustainable logistics.
  • Sustainability is a top priority for us: Not only on our mission but also in our everyday life we integrate sustainability.
  • Be part of something big: Together we are working to make the delivery experience more sustainable, easier and more flexible.
  • Work-life balance is important to us: Benefit from sports offers at the "Urban Sports Club" and regular team events.
  • You will find Liefergrün in the portfolio of international top VCs - We benefit from this through financing, support and consulting.

We are looking forward to meeting you!
