Senior AI Engineer – Generative Geometry (Text-to-CAD) - Python - Pay: R$30,000–R$40,000 per month

**Pay: R$30,000–R$40,000 per month** **Opportunity** This is a **direct hire position** . Structure Studios is an established, profitable, growing company. Our engineers average 9\+ years at Structure Studios. Here at Structure Studios, we built our 25 year reputation by developing award\-winning 3D/AR/VR software that changed how an entire industry does business. Now, we’re adding an AI\-powered layer to give AI the ability to draw via Text\-to\-CAD Using our pre\-existing unique software architecture to feed AI the data it needs (provided by our software team in the format required) to generate smart AI\-assisted 2D landscapes, AI 2D geometry, and AI tools. You will design systems that convert natural language into deterministic, constraint\-valid 2D geometry using our CAD tool API. **Top 5 Reasons to Join Us** 1. We don’t rely on layers of project management—here,  you’ll interface directly with experienced stakeholders. 2. We already have product\-market fit. 3. You won’t build AI demos. You’ll build AI used daily by thousands of professional designers. 4. We're stable. 5. We changed an entire industry once before, and we’re excited to do it again. **Responsibilities** * Design, build, and maintain a **Python back\-end service** for AI\-powered Text\-to\-CAD (no front\-end work required). * Partner with product and backend teams to design deterministic output formats (JSON) for reliable CAD generation. * Fine\-tune LLMs or vision models using curated CAD datasets to improve spatial reasoning and command accuracy. * Design structured prompt systems that reliably generate drawing instructions matching strict geometry schemas. * Prepare and manage **training datasets** for future fine\-tuning. * Define and build the first version of our AI Text\-to\-CAD pipeline. * Ensure the service can scale to handle **thousands of daily requests** reliably. * Collaborate closely with our veteran software team **Qualifications** * 5\+ years professional **Python** experience (production systems), focused on AI libraries (PyTorch). * Experience designing structured\-output LLM systems (function calling, schema enforcement, tool invocation). * Familiarity with computational geometry, polygons, and geometry validation * Strong applied experience with prompt engineering. * Strong problem\-solving and communication skills for cross\-team collaboration. * Fluent English speaking skills **Nice\-to\-Have Skills** * Background in 3D software (Blender, Unreal, CAD, Sketchup). * Knowledge of cloud deployment (AWS/GCP/Azure). **What 6\-Month Success Looks Like** * Text prompts reliably generate production\-valid 2D shapes * AI can generate complete landscape layouts using plant constraints * System supports 1,000\+ daily requests with \<2% geometry failure rate * Output adheres to schema 100% of the time **Hiring Process** Our interview process is quick and to the point. You'll talk with the founders from the very first call, which means we can wrap up the entire process in days rather than weeks. * 5\-min questionnaire * 25\-min call with the CEO to discuss background, experience, and career goals; answer questions; and get take\-home exercise so we can understand how you solve problems * 50\-min review of a past project with Backend Architect * 50\-min culture \+ product sense interview with Director of Operations * Offer extended * Welcome to our awesome team!
