Mechanical Engineer, Factory Automation

About CircuitHubCircuitHub 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 ForWe’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 principlesPrototype mechanical and software fixes on the flyWork autonomously and communicate clearly to a remote teamTake full responsibility for uptime and performance in live productionWhat You'll DoDesign gantries and end effectors in Fusion 360Analyze end effector behavior from video recordings and revise its geometry to improve reliabilityConceive of novel mechanical systems to handle electronics partsInstall, commission and debug robotsPrototype and deploy a new test robot for in-line PCB validationTravel to UK to brief R&D teams and shape roadmap prioritiesKey Tools & TechnologiesSolidWorks and/or Fusion 360 for mechanical designBeckhoff TwinCAT for industrial PLC integrationPython for control and automationLocationIn 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. 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?
