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 $45M 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 full-stack robotics/automation engineers to build and scale our automated factory in Cambridge UK. This is a hands-on, high impact role based full-time onsite at our central Cambridge facility. You’ll be a core part of the build out, development and support of a brand new fully automated factory. You’ll design, deploy and deliver both physical and software systems as well as continually carrying out post deployment optimisations to increase throughput.
We’re looking for individuals who have built full robotic systems, whether as a student, founder, employee or hobbyist. You’ll be expected to integrate software, hardware, and process into functional systems and debug failures under real-world production pressure.
We’re not looking for narrow specialists for this role, we are looking for engineers who can:
Create and adapt PLC code on the fly and under pressure (Beckhoff TwinCat ideally)
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 production system uptime and performance
This role is perfect for an individual who loves to see their own designs through from concept, to build through to deployment. You will be designing, prototyping, iterating and optimising systems constantly, working in a dynamic environment amongst highly motivated peers.
Bonus skills:
Programming and running CNC machinery
Design of chemical handling machinery
Experience working with optics
3D CAD experience, ideally Fusion 360
What You’ll do
Every day is different, on a given day you could be doing anything from forklifting steel fabrications off a lorry and designing end effectors to commissioning linear motors and debugging TwinCAT code. Here are some examples things you might get involved with:
Configure and debug a distributed GigE vision system
Analyze end effector behavior from video recordings and revise the geometry and control approach to optimise throughput and reliability
Specify, test and deploy sensors for monitoring a chemical process
Commission new robotic systems and debug their control cabinets
What CircuitHub can offer
Salary, £50,000 - £110,000 dependent on experience
Think you can bring more than what’s described here? Great! The salary range is not a hard limit, if you are an expert on all of the above we still want to talk to you.
Not quite so experienced, but passionate and want to learn? Also great! Talk to us, we might be able to find a place for you.
Location
This is an onsite role out of our site in central Cambridge working alongside a driven team of automation engineers who are designing, building and supporting the expansion of our Grid PCB assembly system.
Compensation Range: £50K - £110K
