Mechanical Engineer, Factory Automation

Job description

### **About CircuitHub** CircuitHub is reshaping electronics manufacturing with **The Grid**—a factory-scale robotics platform designed to make small-batch, high-mix electronics assembly radically more efficient. Think semiconductor-fab levels of precision applied to the chaotic world of prototyping and low-volume production. The result? A **10x throughput improvement** in one of the world’s most foundational industries. We’ve raised **$20M** from top-tier investors including **Y Combinator** and **Google Ventures**—and we’re already **profitable**. Our customers include industry leaders like **Tesla, Meta,** and **Zipline**. The Grid isn’t a prototype—it’s live, scaling fast, and already delivering real revenue. We’re now building the engineering core that will scale it further. ### **What We’re Looking For** We’re hiring driven Mechanical Engineers to join our factory automation team. This role is focused on the design, development, and commissioning of automated robotic cells that support our advanced manufacturing process. Some software/scripting or PLC/controls capability is preferred but this is primarily a practical mechanical engineering role. This role is suitable for someone who has **built full robotic systems**, whether as a **hobbyist, student, employee,** or **founder**. You’ll be expected to integrate software, hardware, and process into functional systems and debug failures under real-world production pressure. We don’t hire narrow specialists. We want engineers who can: - Diagnose system-wide failures from first principles - Prototype mechanical and software fixes on the fly - Work autonomously and communicate clearly to a remote team - Take full responsibility for uptime and performance in live production ### **What You'll Do** - Design gantries and end effectors in Fusion 360 - Analyze end effector behavior from video recordings and revise its geometry to improve reliability - Conceive of novel mechanical systems to handle electronics parts - Install, commission and debug robots - Prototype and deploy a new test robot for in-line PCB validation - Travel to UK to brief R&D teams and shape roadmap priorities ### **Key Tools & Technologies** - **SolidWorks** and/or **Fusion 360** for mechanical design - **Beckhoff TwinCAT** for industrial PLC integration - **Python** for control and automation ### **Location** **In the first year of the role you must be available to work at least three days on-site at our** [**South Deerfield, Western Massachusetts (90 mins from Boston) facility**](https://maps.app.goo.gl/Z28dMofnouPZ52Ad9). In early 2027 we will establish facilities in Boston, LA and the Bay Area. Early hires to the South Deerfield team will be in an ideal position to lead the new sites. ### **Want to help us build the future of manufacturing?**
