Engineering, All
Telli, Berlin
The role
This role is for engineers who care about velocity and solving real customer problems. You won't just ship code; you will own projects end-to-end, make core product and technical decisions, and shape the trajectory of this company.
Our philosophy is to push the frontier models to the limits of what is possible - and to achieve that, we need your help.
What you will do
Voice AI
Voice AI is one of the hardest technical challenges we have right now. We need to ensure that the voice AI we deliver is fast, reliable, and high-quality.
Topics that we are currently working on
- No-infra RAG using SQLite artifacts downloaded for each call.
- Racing LLMs to use the fastest one at any given moment.
- Shadow-test new transcribers on real calls before switching production traffic.
- Make Voice agents respond faster without reducing quality.
- Make every bad call easy to understand and debug.
Multi-channel agents
Currently, our agents are primarily voice agents, but we will extend their capabilities to be able to handle any channel.
