Description

Fullstack Product Engineer to join our team in building and shipping cutting-edge AI-powered products at serious speed.

Must-Haves

Product-driven mindset : You make tactical decisions fast and care deeply about product outcomes - not just the code.
Langchain experience : You've built real features or products using Langchain and understand the LLM ecosystem.
Completed / working in AI chatbots, with agents, vector DBs, embeddings, and prompt engineering etc
Launched real AI apps : You've taken at least one AI-powered product to market, preferably LLM-based.
Fullstack excellence : You work seamlessly across Ruby (backend) and React (frontend). If you havent worked on Ruby and ROR, it is fine as long as you are willing to vibe code and get the projects going.
Zero-API mentality : You dont rely on an elaborate API layer; you're comfortable making decisions across the stack with minimal abstractions.
Ownership mindset : Youre hands-on, bottom-line accountable, and thrive in unstructured environments.

What You'll Be Doing

Own end-to-end product development using Ruby and React, working tightly with product and design.
Build and iterate fast - days not weeks.
Implement intelligent workflows using Langchain and other LLM frameworks.
Skip the bloated API layers and get things done through smart architecture and direct integration.
Ship high-utility features used by thousands of users.

Bonus : Past experience building tools in CRM, SaaS, or automation.
