Product Engineer

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 $48M from top-tier investors, including Y Combinator, Google Ventures and now Plural and Sten Tamkivi, 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 delivering real revenue. We're now building the engineering core that will scale it further.

 

What You’ll Do

As a Product Engineer at CircuitHub, you will own entire production software systems end-to-end, from understanding operational problems on the factory floor through designing, building, deploying, and operating the software that solves them. You’ll be responsible for entire systems rather than isolated tickets, owning problems from discovery through deployment and operational impact.

This includes building and maintaining the internal operational stack that seamlessly connects planning, materials, purchasing, personnel, and factory processes, transforming complex manufacturing workflows into highly reliable, usable software. You’ll partner closely with factory operators, engineers, and company leadership to ensure CircuitHub’s factories scale smoothly as demand and Grid capabilities grow.

Example Projects:

• Develop production planning tools and inventory/materials-flow systems

• Improve factory operator workflows

• Integrate new automation equipment

• Apply AI and LLMs to automate operational decision making, from purchasing and production planning to machine diagnostics and debugging.

• Build the software systems that coordinate thousands of manufacturing decisions across people, robots, inventory, and suppliers in real time.

 

What We’re Looking For

Must-haves

• Strong PostgreSQL experience: complex queries, performance tuning, and schema design

• Solid data modeling and systems-design judgment

• Hands-on systems integration: stitching together APIs, tools, and workflows that hold up in production

• Strong software engineering fundamentals and the ability to ship production systems quickly and reliably.

• Willingness and ability to travel regularly to CircuitHub factories (US and UK) and spend time on the factory floor partnering closely with operators and engineers.

Nice-to-haves

• Familiarity with manufacturing, logistics, ERP/MRP, or supply-chain systems

• Experience building internal tools or operational software

• Experience keeping mission-critical operational systems fast and reliable

• Comfortable collaborating closely with internal teams on regular basis

 

Who You'll Work With

You’ll work directly with the Head of Internal Software and company leadership to identify bottlenecks and turn them into software systems that improve factory throughput. You'll join the internal software team and work alongside engineers, factory operators, and leadership.

In your first 6–12 months, success looks like owning a meaningful slice of the production operations stack outright and measurably improving the reliability and throughput of the operations it supports.

Location & Work Environment

• Offices: South Deerfield MA, US; London and Cambridge, UK

• Flexible arrangements: remote, hybrid, or in-person

• This is potentially a remote role open to candidates who can maintain at least four hours of daily overlap with both our US East Coast and UK teams.

• While the role can be remote, successful candidates should expect regular travel to CircuitHub factories (in US and UK) and hands-on engagement with production operations.

Compensation

• UK: £80k–£130k

• US: $150k–$250k

• Plus equity
