Senior Software Engineer - Kubbly

Why Kubbly

Most business texts feel like spam. At Kubbly , we are changing that. Messaging app inbox is becoming the most valuable smartphone real estate. People live within their messaging apps. But, businesses struggle to engage their customers here meaningfully without sounding like spam. We solve this with AI agents that predict intent, start the right conversation, and finish the task inside the messaging threads.

We are looking for someone who can help us scale our platform for businesses to deploy their messaging AI agents. If you have a knack for building end to end scalable systems, you'll fit right in. You'd be joining at that perfect stage: proven enough that we know it works, early enough that you'll shape how it grows.

Reasons to join us:

The founders actually built similar stuff before. Piyush and Giorgos have previous experience building similar startups, licensing technologies to Fortune 1000 companies, and 10+ years experience building ML and recommendation systems at Amazon and Goldman Sachs.

We're backed by Bek Ventures (formerly Earlybird Digital East) . HEC-Dow Jones ranked their fund #1 in WSJ by overall performance. They backed UiPath and Payhawk before they were cool.

You'll own the full pipeline, not tickets. Your code won't go through 5 layers of review. You'll have major role in deciding what to be built, how something should work, build it, ship it, and see customers use it.

We actually talk about technical problems. Weekly tech talks, paper discussions, post-mortems on interesting bugs. The founders are engineers first - they'll geek out with you about implementation details.

Competitive comp + equity.
