Mechatronics Engineer

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.
The role
Mechatronics Engineers at CircuitHub own projects end to end. You'll start with a problem, often on our factory floor, and take it all the way to a working machine:

• 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

We work AI-first. AI tools help you scope the problem, drive your CAD, run the calculations and write the machine software. The software side needs basic software engineering skills, not a software background: you'll write it with AI agents, supported by a dedicated software engineering team who build the operating system.
You must have built things before, ideally robots, whether as a hobbyist, student, employee or founder. 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 with a team spread across sites

• Take responsibility for how their machines perform in live production

Things you'll do
This is a design role with hands-on prototyping. For example:

• 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

• Use AI agents to run the engineering calculations, and know when to distrust them

• Machine prototype parts in our in-house CNC shop

• Analyse end-effector behaviour from video and revise its geometry and control approach to improve throughput and reliability

• Program machine behaviour on our in-house robotics operating system, with AI agents doing the heavy lifting

• Specify sensors that catch errors while a machine is running, or monitor a chemical process

• Prototype and deploy a new test robot for in-line PCB validation

• Commission your machines and hand them over to our build team to scale up

• Work across our US and UK sites to share what you've learned and shape the roadmap

Bonus skills

• Experience programming machines, whether PLCs, robot controllers, embedded systems or Python

• Programming and running CNC machinery

• Design of chemical handling machinery

• Optics

Pay and level
£45K–£125K depending on experience, plus equity.
A candidate at the lower end of the range might have:

• Built some systems before, with some exposure to robotics or automation

• Seen parts and subsystems through to manufacture as part of a design team

• Knowledge of designing for machining

• A keen interest in moving their career towards practical robotics

A candidate at the upper end might also have:

• Led the build and deployment of large-scale automated systems

• Written the software that controls their own machines

• Designed for a wide range of manufacturing methods, from machining to sheet metal to injection moulding

• Mentored more junior engineers

The range isn't a hard limit: if you're an expert in all of the above, we still want to talk to you. Not quite so experienced but passionate and keen to learn? Talk to us too.
