## Description

The primary role of the Senior Software Engineer (Python/TypeScript) is to design, build, and maintain both the client-side interfaces and server-side architecture powering our Geology OS. This role plays a critical part in delivering robust, high-performance, and scalable end-to-end solutions that combine agentic AI, cartography, 3D modeling, and automated report generation to support complex exploration workloads., * Architect the Geology OS: design, implement, and maintain full-stack components and services, ensuring they are scalable, secure, and highly available to power our core platform;

 * Build advanced interfaces: develop high-quality, responsive user interfaces (React), integrating cartography, 3D modeling, and interactive data visualizations for an optimal user experience;
 * Engineer robust back-end APIs: develop APIs and back-end services (Python) that integrate seamlessly with the front-end application and third-party platforms;
 * Integrate agentic AI: collaborate with AI engineers and scientists to deploy agentic AI systems directly into the Geology OS enabling sophisticated features such as contextual chat with documents and maps, AI-driven 3D model generation, and automated technical report generation;
 * Cross-functional collaboration: partner with various profiles (AI engineers, back-end engineers, forward deployed engineers, geology experts) to deliver end-to-end features, from database to UI;
 * Lead technical design: take part in architectural decisions for both front-end and back-end systems, ensuring they align with a modern, AI-driven system architecture;
 * Code excellence: write clean, maintainable, and well-documented code for both client and server-side applications;
 * Production ownership: deploy and operate full-stack services in production while monitoring their performance and reliability in a high-stakes exploration environment., * Languages: Python (expert level), JavaScript / TypeScript, Bash
 * Back-End Frameworks: Django / FastAPI and relational database (Postgres)
