Mechatronics Engineer

Userc Dehradun; Cambridge; Remote; GBP 55,000 - 80,000; Full time

Job summary

CircuitHub in Cambridge, UK is seeking a Mechatronics Engineer to own projects end to end on the Grid robotics platform. You’ll move from problem to specification, design mechanisms in CAD, prototype on the in-house CNC shop, and integrate software on our robotics OS.

You should have built things before, ideally robots, and be able to diagnose failures from first principles, prototype fixes, and collaborate across sites in the US and UK.

Responsibilities

• Conceptualize and design mechanisms to handle electronics parts and robotic tasks on the factory floor.
• CAD design of gantries and end effectors, with in-house tools such as Fusion 360.
• Prototype parts and validate with engineering calculations and testing on the CNC shop.
• Program machine behavior using in-house robotics OS, with AI assisting CAD and calculations.

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

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

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.
