What they're building

The Grid, a factory-scale robotics platform for small-batch, high-mix electronics assembly strong signal

Today: "Get your PCB prototypes from design to delivery in weeks days with CircuitHub's automated, on-demand manufacturing."

Roles: Haskell Engineer · Mechanical Engineer - Factory Automation · Full-Stack Robotics/Automation Engineer · Automation System Build Engineer · Mechanical Engineer, Factory Automation · Full-Stack Robotics Engineer

Requirements mention: Beckhoff TwinCAT · PLC systems · distributed GigE vision system · robotic cells · in-line PCB validation · Haskell · hard optimization problems

Inference: The Grid appears to be the in-house automation behind the on-demand assembly the site sells. They are extending it across mechanical, controls, vision and planning software.

New fully automated factory in Cambridge, UK strong signal

Today: "3 day full turnkey fab and assembly by default. Made in the USA"

Roles: Full-Stack Robotics/Automation Engineer · Mechanical Engineer - Factory Automation · Automation System Build Engineer

Requirements mention: automated factory · designing and commissioning machined components · PLC commissioning/debugging · cabinet wiring · commissioning and testing

Inference: they are setting up a second production site in Cambridge, UK, alongside the US operation in South Deerfield. All Cambridge and UK roles opened between June and July 2026.

Internal operations and manufacturing software weak signal

Today: "CircuitHub allows you to easily manage an inventory of custom parts or pull from our shared common parts."

Roles: Product Engineer (Operations & Manufacturing Software)

Requirements mention: ERP/MRP · supply-chain systems · internal tools

No inference: one open role only.

How to use this

If you're applying: Most open roles are mechanical, controls and robotics work for The Grid. Three are on site at a new automated factory in Cambridge, UK, and three are in South Deerfield, Massachusetts, USA. Check the listed requirements against your experience before applying, especially Beckhoff TwinCAT, Fusion 360 and PLC work. Posted ranges include £35,000–£60,000 (Automation System Build Engineer), £45,000–£100,000 (Mechanical Engineer - Factory Automation), £50,000–£110,000 (Full-Stack Robotics/Automation Engineer), and UK £70k–£130k / US $130k–$250k plus equity (Haskell Engineer).

If you're selling or recruiting: 7 of 8 open roles are in Engineering, split between Cambridge, UK and South Deerfield, Massachusetts, USA. All UK roles opened in June–July 2026 and tie to a new automated factory in Cambridge, so ask about that build-out and The Grid. No roles opened or closed in the last 30 days.
