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 to automate operational processes like purchasing and machine debugging
Build software that coordinates work across people, robots, and suppliers

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.

Nice-to-haves

Familiarity with manufacturing, ERP/MRP, or operations software, and an understanding of production planning and materials flow
A background in software, automation, or manufacturing engineering
Experience keeping mission-critical operational systems fast and reliable
Comfort collaborating closely with operators and production teams on the ground

Who You'll Work With

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. You will work closely with Head of Internal Software.

Location & Work Environment

Flexible arrangements: remote, hybrid, or in-person
Offices: South Deerfield, MA; London; and Cambridge, UK
Remote candidates: based in the US or UK
Expect regular time on the factory floor (Cambridge and South Deerfield) to work directly with operators, planners, technicians, and engineers

Compensation

UK: £80k–£130k
US: $150k–$250k
Plus equity
