Pango | Full-stack Software Engineer | On-site (hybrid) in Stockholm, Sweden | Full time

Pango is building the world's first Agentic Operating System for e-commerce logistics. Our vision is to create the AI e-commerce employee of the future. We are forming our core team in Stockholm and are looking for exceptional engineers. We are based at the SSE Business Lab, where companies such as Klarna, Voi, Budbee or Legora originated.

* You are happy to take on work that in a large company is divided into a dozen roles, and execute it all at a good enough level.

You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.
