sennder - Sr/Lead Backend Engineer (Discovery team) - Barcelona - 65/100K (fixed + bonus + equity)

sennder is digitizing Europe’s logistics. We are a growing team looking for a Senior/Lead Software Engineer (Backend) to help us on our journey to revolutionize road freight logistics. You would join our Discovery (pod) team in Berlin or in our new Tech Hub in Barcelona.

The Discovery team strives to facilitate the discovery of truck loads through our Marketplace as a means to maintain the carrier’s truck as busy as possible to help them grow and have profitable tours. Our team also takes care of one of the core pieces of sennder’s brokerage system to match carriers with shippers, the Bidding Service. The latter contains the business logic to execute the bidding actions in the Marketplace and connects to other services in sennder’s microservice architecture.

We value humility and we’re as interested in your character as we are in your talent. Please apply, even if you feel you only meet part of our listed criteria. Diversity drives our innovation and we offer a collaborative, dynamic and international work environment. Just be yourself. We are excited to meet you and for you to join us in shaping the future of the logistics industry in Europe.

As a senior / lead software engineer, you’ll have an opportunity to create a substantial business impact by building new products, features and services that delight carriers across Europe. You’ll contribute to the architectural vision and technical direction across the whole Discovery team, delivering on the roadmaps and increasing team velocity whilst innovating, applying best practices and helping your colleagues to grow.
