Senior Full Stack Engineer (Python+TS, AI Project)

Hi there :)

Thanks for checking in to find out about our open position. We´ll provide as much information as possible, but please feel free to reach us if you have further questions. We´ll be happy to see your application, even if there are skills you don't quite master!

About Us

At South Geeks, we connect top LATAM engineers with global teams that value autonomy, technical excellence, and long-term collaboration. We focus on building strong relationships with our partners and providing meaningful, challenging work for our talent.

About the Client

Our client is a commercial real estate technology company building a modern platform for brokers. Their product automates complex document workflows and integrates advanced AI-driven analysis. They prioritize engineering rigor, thoughtful architecture, and strong communication across their team.

About the Role

We’re seeking a highly independent Senior Full Stack Engineer to design and deliver core functionality for a large-scale web application built with React/TypeScript, Python/FastAPI, and PostgreSQL. This role is ideal for someone who excels at architectural planning, anticipates downstream impact, and thrives in an environment where alignment and communication are essential.

You’ll join two other senior engineers, each owning substantial parallel features, and contribute to a fast-moving team with high expectations for clarity, initiative, and iterative delivery.

Key Responsibilities

• Lead architectural planning, create technical proposals, and secure alignment with other senior engineers before implementation.

• Architect, design, and implement full-stack features across React/TypeScript, FastAPI, and PostgreSQL.

• Develop and maintain complex UI components, including CKEditor integrations and DocX formatting workflows.

• Build and optimize a multi-LLM orchestration layer that triggers hundreds of model calls per operation. Work with a sophisticated AI layer using multiple LLM orchestrations, not just single-call ChatGPT wrappers.

• Break down work into GitHub issues, maintain transparent progress, and ship verifiable features weekly.

Required Skills & Experience

• Advanced proficiency in React/TypeScript, Python/FastAPI, and PostgreSQL.

• Proven ability to architect systems, document plans, and communicate technical decisions clearly.

• Experience integrating or orchestrating LLM APIs (OpenAI, Anthropic, etc.).

• Experience with CKEditor and document manipulation workflows.

• Excellent communication, planning, and independent execution skills.

Nice to Have

• Experience with data-heavy or document-heavy platforms.

• Background with AI workflow automation beyond basic chat interfaces.

Our Team

We strive to create an inspiring and growth-oriented environment where everyone feels valued, heard, and empowered. We promote both personal and professional development, with individualized support for your needs and goals. We aim to build a space where everyone can thrive.
