## Description

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.

 - Design API and data contracts that hold up over time, with type-safe transforms between the API, the domain and persistence.

 - Run what you build. Instrument it, know how it fails, change live data safely, and be the person who works out why it broke.

 - Deliver with coding agents as a matter of course, and verify what they produce before you rely on it.




YOUR SKILLS AND QUALIFICATIONS

 - Strong, hands-on backend engineering in TypeScript and Node as your primary working la
