About the Team
We are Quadcode, a fintech company excelling in financial brokerage activities and delivering advanced financial products to our global clientele. Our flagship product, an internal trading platform, is offered as a Software-as-a-Service (SaaS) solution to other brokers.
We’re looking for a Python Backend Developer (AI) — an engineer who knows how to turn neural networks into real, working product features: launching, adapting, and optimizing models, and integrating them into a production-ready system.
What we’re building
We’re creating the AI IDE of the future — an intelligent environment for developers and AI enthusiasts across desktop, mobile, and web. It’s a place where you can build not just code, but also images, audio, video, and design — powered by cutting-edge LLM agents.
This is an AI startup inside a stable product company, right at the exciting early stage. We’ve already built our MVP, are testing before release, and have real users and a strong team of engineers on board.
Our product uses advanced AI models and technologies, including:- The latest LLMs.- Modern AI tools like RAG, LangChain, LoRA, and more.- Various model types — image, video, audio, etc.- AI agents and pipelines.
We work in the GMT+3 time zone (team daily meetings are at 12:00 pm).
Join us today, and let's shape the future of fintech together!
Note: All applications will be treated with strict confidence. We thank all applicants for their interest, however, only those candidates selected for interviews will be contacted.
