Full-Stack Automation Engineer

*Recent Graduates ONLY IN Kitchener, Cambridge, Waterloo or Guelph*

Project Overview

We are building a cutting-edge platform to fully automate the production of customized goods via 3D printing. We are seeking a highly motivated and specialized Full-Stack Automation Engineer to build the core intelligence and financial oversight of this system. This role involves creating an end-to-end digital manufacturing workflow, from order placement to final print, including real-time tracking of costs and profits.

The ideal candidate will not just be a developer, but a true "Maker" with significant personal experience in 3D printing who understands the process from CAD file to final part, and the economics of running a print operation.

Core Responsibilities

As the lead engineer on this project, you will be responsible for the full-stack architecture and implementation across three main areas:

1. E-commerce & Core Automation )

• Develop robust, scalable backend services using to monitor for new orders across Shopify, Amazon (Selling Partner API), and Etsy.
• Implement secure API integrations to ingest order data, customer customizations, and shipping details.
• Build data pipelines using Python to preprocess order inputs for the Machine Learning model.

2. Inventory & Profit Management (Backend Business Logic)

• Design and implement a robust database schema to act as the Inventory Tracker, monitoring stock levels of various filaments (by type, color, weight/length) and other raw materials.
• Develop Profit Management logic in the backend to automatically calculate:
• Cost of Goods Sold (COGS): Based on the exact amount of filament consumed for a print (from ML-optimized slicer data) and fixed costs.
• Gross Profit: By subtracting COGS from the sales price retrieved from the e-commerce order.
• Ensure inventory levels are decremented automatically upon order fulfillment.

3. Front-End Interface & Analytics (React)

• Develop a clean, highly responsive single-page application (SPA) using React to serve as the main control and monitoring dashboard.
• Implement real-time visualizations for inventory levels, print queue status, and core Profitability Metrics (e.g., profit per order, material consumption rates).
• Design an intuitive interface for manual inventory adjustments and viewing historical profit reports.

Required Skills & Qualifications

*RECENT GRADUATES ONLY*

Technical Mastery

• Full-Stack JavaScript: proficiency in React (Front-End) and (Back-End).
• Database & Business Logic: Strong experience in designing scalable database schemas (SQL/NoSQL) and implementing complex financial/inventory management logic.
• E-commerce APIs: Proven, hands-on experience integrating with and managing data from Shopify, Amazon, and/or Etsy APIs/Webhooks.
