CircuitHub Raises $28M Series A to Expand Robotic PCB Manufacturing

CircuitHub is scaling automated, software-driven printed circuit board (PCB) production across the United States and Europe. The company announced a $28 million Series A funding round led by Plural, as reported by Electronics Weekly, bringing total capital raised to roughly $48 million.

Hardware teams have historically faced long delays when procuring assembled electronics, often waiting weeks or months for overseas assembly in hubs like Shenzhen. CircuitHub operates an automated 5,000-square-foot facility in South Deerfield, Massachusetts, nicknamed "The Grid." The setup uses automated robotics, magnetic levitation movers, computer vision, and AI to compress production cycles from months to days, running single prototypes side by side with orders of up to 10,000 units.

To date, the company has delivered more than 2 million boards and mounted over 150 million components for more than 20,000 engineers developing autonomous vehicles, satellites, robotics, and clean energy systems.

Automating the Electronics Assembly Line

CircuitHub functions like an on-demand cloud computing service for physical hardware. Through a web interface, hardware engineers upload their circuit board design files, receive an instant quote and lead time, and configure their run without manual back-and-forth negotiations.

Inside the South Deerfield factory, magnetic levitation transport devices carry boards and component pallets across an array of tiles between automated pick-and-place gantries, soldering equipment, and inspection stations, as shown in a tour by S3 | Science, Startups, & Stories. Each board moves through a customized route depending on its technical requirements, eliminating manual retooling delays between varying designs. According to GIGAZINE, CircuitHub's Grid Proto service delivers small prototype runs in as few as three to four days, compared to a median of nine days from factories in Shenzhen.

The company maintains an on-site inventory of around 50,000 unique component SKUs ready for immediate loading onto machines. By stocking high-value integrated circuits along with passives, the line reduces setup delays and buffers against component attrition during prototyping.

Leadership and Technical Stack

CircuitHub was founded in 2011 by CEO Andrew Seddon alongside former co-founder Jonathan Friedman, who left the company in 2013 to lead Assembly. Seddon holds an electrical and computer engineering background from the University of Leeds and previously led computer vision and robotics engineering teams at Cambridge Signal Processing and Oxford Metrics.

On the software side, CircuitHub operates a functional programming stack:

• Backend: Haskell API server using GHC 8, Yesod, and Opaleye.
• Frontend: Elm, using functional reactive programming for standalone GUI applications.
• Database: PostgreSQL queried with Opaleye and Rel8.
• Infrastructure: NixOS for development environments, continuous integration, and deployments, hosted on AWS and Heroku.
• Observability: Prometheus and Grafana for metrics and telemetry.

Seddon explained on an episode of Pathfounders that the factory operates over 100 kilowatts of on-site compute to run real-time inference and computer vision defect detection, along with agentic models coordinating factory workflows.

Engineering Growth and Factory Expansion

With plans to expand production capacity fivefold and launch a second automated Grid facility in Europe, CircuitHub is actively hiring across robotics, optimization, and software engineering. The company's R&D operations remain split across London, Cambridge, and Massachusetts.

For on-site operations in South Deerfield, the team is recruiting a Full-Stack Robotics Engineer ($140,000 to $250,000) and a Full-Stack Robotics Engineer Summer 2026 Intern ($6,000 per month). Both roles require working on-site in Western Massachusetts to maintain hardware and software for The Grid, tune camera networks, fix robot reliability issues, and deploy new mechanical and software subsystems.

Distributed engineering roles allow remote work from the United States or the United Kingdom:

• The Operations Research Engineer (£80,000 to £150,000) will establish a new team dedicated to scheduling and pricing optimization for The Grid, developing quoting algorithms and modeling capacity-based revenue.
• The Haskell Engineer (£80,000 to £150,000) will build manufacturing execution and enterprise resource planning systems alongside robotic path-planning tools using Haskell, Elm, Nix, and PostgreSQL.
• The Computer Vision Engineer (£80,000 to £150,000) is a founding role responsible for architecting labelling pipelines, building front-end labelling tools, and training defect-detection and bin-picking machine learning models using Python, TypeScript, React, OpenCV, and PyTorch.
