About Seljax

Seljax is an estimating & 3D design software that has been serving the building materials industry for over 30 years. Our platform helps lumber yards, dealers, and contractors produce accurate estimates and 3D designs for homes, decks, garages, and post frames.

We are now launching a new project that is a AI-driven system that can take a PDF of a house blueprint and automatically generate a complete material list. This technology will transform how the industry handles estimating, making it faster, smarter, and more accurate.

Role Overview

We're looking for an AI Engineer to lead the technical development of Seljax AI House. In this role, you'll design and build the AI pipeline that turns PDFs into structured material lists. You will be tasked with creating a AI that can read a PDF blueprint of a house or any residential drawing.

Key Responsibilities

Develop and train AI models to analyze residential blueprints/PDF plans. Implement OCR to extract text, labels, and notes from drawings. Use computer vision to detect symbols and structural components (walls, doors, windows, etc.). Create logic to convert detected elements into an accurate bill of materials. Build scalable backend APIs (Python/FastAPI or Flask) and integrate with the Seljax platform. Collaborate with the Seljax team to test and refine outputs for real-world accuracy.

Required Skills & Experience

2+ years of AI, ML, or computer vision development experience. Strong proficiency in Python and frameworks like PyTorch or TensorFlow. Experience with OCR technologies (e.g., Tesseract, EasyOCR). Familiarity with PDF parsing, image processing, or object detection. Solid understanding of backend APIs and cloud infrastructure (AWS, Azure, or GCP). Excellent problem-solving skills and ability to work independently.
Nice to Have

Experience in the construction tech or building materials industry. Knowledge of estimating or material takeoff workflows. Frontend skills (React or similar) for building visual interfaces. Experience with MLOps or AI deployment pipelines. Leadership interest or experience mentoring developers.
Why Join Seljax

Be part of a trusted, industry-established company with a startup-level innovation project. Lead development of an AI system that will redefine estimating for lumber yards.
