why telli?

telli is building AI voice agents that change the way businesses communicate with their customers. Voice is the most natural way humans communicate. However, high-quality voice interactions have historically struggled to scale, leading businesses to rely on clunky user interfaces and compromise on customer experience.

AI dramatically improves both quality and scalability. However, the technology alone isn't enough. At telli, we believe businesses need a simple, tailored tool that helps them transform their customer communication channels. This is what we’re building! The opportunity is huge, and the time is now - and that’s why we need YOU!

About The Role

We’re looking for a stellar full-stack software engineer to join us in Berlin.

team & culture

We are bringing together a small all-star team right in the heart of Berlin and are looking for people excited to build the future with us. Join us (Finn, Philipp, Seb, Simon, and Paulus) on this quest!

We care deeply about doing excellent work, and we’re looking for a like-minded software engineer to join our product engineering team.

Thriving At Telli Requires a Few Core Skills

Product mindset: Our tech stack includes TypeScript, React, Node, Postgres as well as temporal.io. But more than familiarity with any specific technology, we value a customer-centric approach and ability to ship end-to-end features.
Ability to work fast in a high-ambiguity environment: As an early-stage startup, we’re inventing a product as well as building it. We’re moving fast. If you have a proven track record of delivering high-quality software in a strong engineering team, that’s a big plus.
Desire to work out of our HQ in Berlin: We believe quality of interactions is higher in an in-person environment. We collaborate deeply and often communicate by tapping one another on the shoulder.
