## Job description

## 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](https://www.linkedin.com/pulse/factory-scale-robot-andrew-seddon-99ive/) 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.

## Overview

- CircuitHub is primarily built using a combination of Haskell, Nix, and PostgreSQL, deployed to both AWS and bare metal machines. We use a significant amount of open-source technology, and also try and give back where possible (for example, both [Rel8](https://github.com/circuithub/rel8) and [Fast Downward Haskell bindings](https://github.com/circuithub/fast-downward)).
- CircuitHub spans a vast problem space. Challenges include computer vision (OpenCV), machine learning (PyTorch), hard optimization problems (Z3/MiniZinc/OR-Tools), and all the normal engineering challenges of building both web-based customer-facing and internal tooling.
- We work on manufacturing execution systems, enterprise resource planning, and robotics. [An old video from Haskell Exchange 2019](https://youtu.be/gl2Ze1WmrYY?si=zlFrqALU7DaPfS65&t=282) hints at what we are up to on the robotics side. We have progressed significantly since then!
- These roles are remote (any location), in-person, or hybrid, depending on preference.
- We have offices in South Deerfield - USA, Cambridge, and London, UK.
- Salary depends on the candidate and location, but as guidance in the UK, a likely range is £70k to £130k and in the US $130k to $250k, with additional equity.
- CircuitHub has raised $48M from top-tier VCs and has been going for about ten years. CircuitHub is profitable, with tens of millions in revenue. Small team (CircuitHub is ~50 employees) with tremendous growth opportunity and low risk. We are aiming to 10x capacity through 2027 in both our existing Massachusetts factory and expand into Europe.

## Team/Environment/Role

Our R&D team is more than 20 people, with eight engineers working directly on the Haskell code base. We are looking to expand the team significantly this year. We have many exciting problems to solve, from robotic path planning to more conventional web products. We are happy to consider candidates without commercial Haskell experience, but your other skills and experience would need to compensate. A possible profile, for instance, would be a professional robotics background with some hobbyist FP experience. Conversely, for experienced Haskellers without experience in our domain, we will look for interests that correlate with what we are trying to accomplish. Life is too short to work on something you are not passionate about!

Location Work remotely, or from one of our labs in the UK (London, Cambridge) or USA (Boston)

## About CircuitHub

## Company Overview
- **One-liner**: CircuitHub provides on-demand, automated circuit board assembly and manufacturing, enabling hardware companies to prototype and produce small batches at speed.
- **Entity Type**: Private (Venture-backed; Series A)
- **Headquarters**: South Deerfield, Massachusetts, USA (with additional locations in London, UK)
- **Founded**: 2012
- **Founders**: Rehno Lindeque (CEO) and Andrew Seddon (CTO)

## Core Business
- Primary industry: Electronics Manufacturing / Hardware Manufacturing
- Target customers: B2B, serving hardware companies in self-driving cars, satellites, 3D printing, robotics, aerospace (e.g., Tesla, NASA, Zipline), and other sectors requiring rapid prototyping and low-volume production.
- Mission or purpose: "To fix rapid electronics manufacturing" and make it possible for hardware companies to design and iterate as fast as software companies.

## Products & Services
- **The Grid (Automated Factory Platform)**: A proprietary, factory-scale robotics platform that delivers a 10x improvement in speed and cost for small-batch electronics production. This is the core technology that enables rapid, on-demand assembly.
- **Full Turnkey PCB Assembly**: Offers assembly from 1 to 10,000 units. Users upload EDA files (Altium, EAGLE, KiCAD) and receive a real-time quote within five minutes. Standard lead time for full turnkey orders is 3 days.
- **Shared Parts Inventory**: A shared inventory of 35,000+ common parts, reducing the need for customers to source and stock components. They also offer to stock custom parts for repeat customers.
- **Virtual Build & Board Viewer**: A browser-based tool that previews the board and component placements before ordering, helping to catch errors early in the process.
- **Real-time KPIs**: CircuitHub is the first in the industry to publish real-time manufacturing performance metrics, providing transparency on delivery times and quality.

## Market Standing
- **Valuation / Funding**: Total funding of $30.3M (as of latest reports). Key rounds include an $18M raise from Y Combinator and Google Ventures, and a more recent $28M raise (likely a Series A or extension) announced in 2025.
- **Key Metric**: Annual revenue estimated at $5.2M (based on available data). More significantly, the company reports having shipped 87.4M+ boards and placed 1.57M+ parts, with over 20,000 engineers trusting the platform.
- **Notable Investors/Partners**: Y Combinator (Winter 2012 batch), Google Ventures (GV).
- **Growth Signals**: The company describes itself as the "fastest growing electronics manufacturer in the USA." They have announced a "10X capacity going into 2027," indicating aggressive scaling. Notable customers include Tesla, NASA, and Zipline.

## Competitive Advantages
- **Speed & Automation**: The core moat is their proprietary software and robotics platform ("The Grid") that automates the traditionally manual and slow process of PCB assembly, enabling 3-day standard lead times.
- **Transparent Pricing & Metrics**: They offer real-time, instant quoting and publish live KPIs, which is highly unusual in the contract manufacturing industry and builds trust with engineering customers.
- **Shared Inventory Model**: By stocking 35,000+ common parts, they solve a major pain point for hardware startups and engineers: the cost and delay of sourcing components for small runs.
- **Tech-First Culture**: The company is built around a modern tech stack (software engineering, robotics, computer vision), which is a significant differentiator from traditional manufacturing firms.

## Strategic Focus
- **Scaling Capacity**: The company is aggressively scaling its manufacturing capacity (10x into 2027) to meet growing demand from robotics, aerospace, and automotive sectors.
- **Deepening Automation**: Continues to invest in its software and robotics platform to further flatten the price curve for low-volume production and reduce lead times.
- **Expanding Customer Base**: While serving large names like Tesla and NASA, the platform is designed for engineers of all sizes, from solo inventors to large R&D teams, suggesting a focus on broad market capture.

## Why Work Here
- **Culture & Mission**: The company is on a mission to "fix rapid electronics manufacturing," offering employees the chance to solve real-world problems in hardware and manufacturing. They describe themselves as a "dynamic bunch of exceptionally hard-working people."
- **Engineering Focus**: The company is built around a modern tech stack, with open roles for Haskell Engineers, Full-Stack Robotics Engineers, Computer Vision Engineers, and Operations Research Engineers. This is an ideal environment for engineers who want to apply software skills to physical manufacturing.
- **Remote-First Policy**: CircuitHub is a remote-first company with a global team. Roles are open in the US (Massachusetts and West Coast) and the UK (London). They support a mix of remote work and co-working spaces for local teams.
- **Benefits**: Competitive compensation, comprehensive health benefits, stock options, flexible paid time-off (PTO), and growth opportunities.
- **Team**: A small, rapidly growing global team of approximately 58 people (as per Y Combinator profile), offering a high-impact environment.
