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

  • Comfortable 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, US; 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 and engineers

Compensation

  • UK: £80k–£130k

  • US: $150k–$250k

  • Plus equity
