Humanoid robots doing backflips are super cool, but to be useful they need to be able to listen, communicate, and operate in the world. Your role in our organization would be to help make that a reality by developing the cloud-based side of our robots that makes them intelligently understand the people interacting with them.

What you'll do

Use robots that cost more than most cars to evaluate and test new features
Iterate on software deployed to customer's robots in the real world
Improve our composite voice pipelines using the latest state of the art models
Add and improve features like knowledge storage/retrieval, smarter turn taking, automatic personality tuning
Create clever approaches to reducing latency and make interactions feel more natural

What we’re looking for

Experience with cloud development (AWS, GCP, Kubernetes)
Experience with latency sensitive applications (voice pipelines, video games, streaming)
Experience with voice AI
High ownership of product features
Addiction to observability metrics
Excellent taste in developer tooling

Technology

Our cloud code is primarily Python 3.14 and it uses a custom UDP-based streaming protocol to communicate with the robots
We deploy at edge locations across the world in GCP and AWS

Who will you work with

Self driving engineers from Argo, repeat YC founders, CERN physicist, Emmy winning animators
Previously built: a web browser (SigmaOS), self-driving cars (Argo), radiation detectors on the ISS, and more.

Why we are working on this - and why you should!

Robots should feel like C3PO or Wall-E, not Terminator or iRobot
We started solving voice for hardware - now we work with the biggest humanoid companies in the world
Robots and people must work side-by-side and therefore robots must be delightful

About the company

Lightberry develops software to make any robot emotionally intelligent and socially aware.

Our robots are learning to behave naturally around humans: they listen, speak, see, and navigate the world like we do.

We work with multiple robot makers, including the #1 humanoid robot manufacturer in the world, Unitree. Lightberry is backed by top funds including Y Combinator, Liquid2, a16z Scout, and operators at NVIDIA, Meta, Google, and more.

Our software is currently state of the art in human-robot interactions.
