Freelance Senior Backend Engineer (all genders)
About Babbel Labs
Babbel Labs is building the future of language learning. We are an AI-first, independent company within the Babbel group, based in Berlin. Our teams bring AI, research and product together to ship experiences that set a new standard for how people learn.
The role
Babbel Labs is rebuilding how learning content is created, stored and served, and how we decide what a learner sees next. The architecture for that is being set now, by a small number of engineers, and this role is one of them.
You will build and run the services behind it, in a serverless-first TypeScript and Node stack on AWS, owning them from the contract at their edge to their behaviour under load.
This is a senior individual-contributor role. You will design, build, ship and operate, and the seniority shows in the decisions you own rather than in a team reporting to you.
How you'll make an impact
Build and evolve services across our learning platform, owning each one from its API contract through to what runs in production.
Take on services you did not write, alongside the people who did.
