København, Denmark Langstack Full time

At Langstack, we’re simplifying how software is built. Langstack is a visual development platform that makes it easy to develop and deploy backend applications in multiple programming languages.

Why consider us

Our work spans from compiler designs to event streaming, clustering, and microservices. It's ambitious, and it’s a lot of fun. On the backend, you'll be working on modern architectures and deep designs with plenty of opportunities to grow professionally.

As a Senior Backend Engineer and Architect, you’ll be involved throughout the product life cycle across idea generation, design, prototyping, execution, and shipping. You’ll collaborate closely with product and engineering to shape and build powerful features. You’ll be involved in high-level product and technical decision-making, as well as diving deep into the weeds to unblock those around you and write thoughtful, maintainable code.

How we work

Langstack’s culture is down to earth, human, and reflects our shared passion for building software products. We’re working as a distributed team. Some work from our office, some work from home, and others just work where they feel most comfortable and productive. Our digital HQ is on Discord, and our brick and mortar HQ is centrally located in Copenhagen, Denmark.
