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).

Tasks

    • Developing the backend of an AI IDE, responsible for integrating LLM models into the product.
    • Building RAG components and pipelines using LangChain, LlamaIndex.
    • Deploying, configuring, and optimizing large language models (LLMs) — both cloud-based and local.
    • Designing and maintaining REST/gRPC APIs for interaction with AI modules.
    • Integrating multimodal models (via API and locally).
    • Working with image, video, and audio generation using Flux, Qwen, OpenAI, Google, Sora, Kling, Suno, and others.
    • Building services for context, prompt, and request management for AI models.
    • Building next-generation AI features for smart code generation and seamless autocompletion.
    • Optimizing the performance, scalability, and stability of AI features.
    • Owning technical tasks end-to-end — from concept to release and maintenance.
    • Collaborating closely with AI engineers to turn ideas into production features.

Requirements

    • 3+ years of experience in Python backend development.
    • 2+ years working with AI tools (RAG, LangChain).
    • Hands-on experience building intelligent pipelines and agents — LangChain, LlamaIndex, Autogen, or your own solutions.
    • Experience integrating models into production features (via APIs, OpenAI, Claude, etc.).
    • Understanding of LLM architecture and experience using models via API/SDK.
    • Solid skills in designing microservices and REST/gRPC APIs.
    • Experience with multimodal systems — generating/processing images, video, and sound.
    • Strong database knowledge (PostgreSQL, Redis).
    • Experience with Docker, Kubernetes, CI/CD.
    • Independence, clean code, and the ability to deliver features fast and reliably.
    • A genuine passion for AI and startups.
    • Fluent Russian, English B1.

Nice to have

    • Hands-on experience with LLM.
    • Prompt engineering background.
    • Advanced LangChain scenarios.
    • Experience working with vector databases.

We offer

    • Full-time remote work (External Vendor contract).
    • Competitive compensation (EUR, USD, or crypto).
    • Flexible working hours.
    • The opportunity to show creativity, generate ideas, and directly influence the architecture of the AI product.
    • Access to cutting-edge AI tools and platforms.
    • A team of professionals specializing in AI.
    • Positive and friendly atmosphere.
With a team of 500+ creative and tech-driven people across the globe, Quadcode is the place where ideas turn into impact, where every project is a chance to grow, innovate, and make your mark.
