About CircuitHub
- CircuitHub is reshaping electronics manufacturing with The Grid, a factory-scale robotics platform that makes small-batch, high-mix electronics assembly radically more efficient. Think semiconductor-fab precision applied to the chaotic world of prototyping and low-volume production: a 10x throughput improvement in one of the world's most foundational industries.
- We've raised $45M from top-tier investors including Plural, Y Combinator and Google Ventures, and we're already profitable. Our customers include a major EV maker, a top AI lab and many of the worlds largest companies.
- The Grid isn't a prototype. It's live, scaling fast and delivering real revenue, and we're building the team that will scale it further.
About the role
- Mechatronics Engineers at CircuitHub own projects end to end, taking problems from the factory floor all the way to working machines.
- The role involves designing in CAD, prototyping, machining parts in an in-house CNC shop, and bringing machines to life with software on an in-house robotics operating system.
Responsibilities
- Understand the problem and turn it into a clear specification
- Generate ideas and choose the right mechanism
- Design it in CAD and prove it out with the engineering calculations
- Prototype and build it, machining parts in our in-house CNC shop
- Bring it to life with software on our in-house robotics operating system
- Conceive new mechanisms to handle electronics parts and other robotic handling tasks, using AI to scope and specify the problem
- Design gantries and end effectors in Fusion 360
- Machine prototype parts in our in-house CNC shop
- Program machine behaviour on our in-house robotics operating system, with AI agents doing the heavy lifting
- Commission your machines and hand them over to our build team to scale up
Requirements
- Must have built things before, ideally robots, whether as a hobbyist, student, employee or founder
- Diagnose system-wide failures from first principles
- Prototype mechanical and software fixes on the fly
- Work autonomously and communicate clearly with a team spread across sites
- Take responsibility for how their machines perform in live production
Preferred qualifications
- Experience programming machines, whether PLCs, robot controllers, embedded systems or Python
- Programming and running CNC machinery
- Design of chemical handling machinery
- Optics
Benefits
- £45K–£125K depending on experience
