Senior AI/ML Engineer - Remote
Why Kubbly
At Kubbly , we're changing how businesses actually talk to their customers. We built a predictive AI platform that lets brands have real conversations with people through email, text, and WhatsApp. Our system figures out what each person will probably want next and knows when they're most likely to care. We're not sending marketing spam, instead we're starting actual conversations. People can even finish their orders right there in the chat, which we still think is pretty wild.
We need someone who can help us scale this whole personalized engagement. If you have a knack for building systems that can predict what people want and actually care whether conversations feel real or like talking to a bot, 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) . They backed UiPath and Payhawk before they were cool. They're founder friendly, provide immense value to their portfolio companies and don't micromanage.
-
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.
🚀 About the role
At Kubbly , we believe AI will really change the way customer engagement works.
