Cherry Ventures is supporting our portfolio with this hire.About the role

we’re looking for an ambitious founding engineer with super high agency!

  • work closely with our customers, understand their problems, and come up with killer product features
  • build scalable backend infrastructure to handle thousands of AI phone calls a day
  • own high stakes projects end-to-end
Team & culture

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

Winning at telli requires a few core skills:

  • product mindset: our tech stack includes TypeScript, React, TanStack, 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 in-person from 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.

What makes you a great fit
  • you enjoy challenging work and going the extra mile
  • your skills have significant (but not necessarily 100%) overlap with what we do – frontend engineering, server development, databases, cloud providers, LLM & Voice AI
  • you enjoy contributing to the entire development stack
  • you want to have an impact from day one
  • you want to work with smart and friendly people with (self-reported) low ego
You may not make a good fit if…
  • you prefer a remote-first environment
  • you like to work on your own with minimum collaboration
  • you want to work 9-5
  • you have no prior experience in software engineering teams
Perks
  • salary range: €70k - €120k
  • equity range: 0.3% - 1.0%
  • access to any (AI) tool that makes you more productive
  • gym subscription
  • a bright and beautiful office in Berlin Mitte
  • company trip to San Francisco in fall 2025
