## About CircuitHub

CircuitHub is reshaping electronics manufacturing with The Grid, a factory-scale robotics platform that makes small-batch, high-mix electronics assembly radically more efficient. Think semiconductor-fab precision applied to the chaotic world of prototyping and low-volume production: a 10x throughput improvement in one of the world's most foundational industries.

We've raised $45M from top-tier investors including Plural, Y Combinator and Google Ventures, and we're already profitable. Our customers include a major EV maker, a top AI lab and many of the worlds largest companies.

The Grid isn't a prototype. It's live, scaling fast and delivering real revenue, and we're building the team that will scale it further.

## What you'll do

• **Inspect boards.** Improve automated optical inspection that finds missing, rotated and wrongly placed parts and bad solder, working alongside our AI agents.
• **Pick reliably.** Train and deploy the models that find parts in bins and trays, centre them on the nozzle and catch a clumped or dropped pick.
• **Align precisely.** Fiducial detection, calibration and image alignment for placements measured in fractions of a millimetre.
• **Build the data loop.** Decide what to capture, build labelling tools, and turn operator verdicts into training data.
• **Go fast.** Work with our high-speed cameras and GPU capture pipeline to move vision closer to real time.
• **Measure it.** Track accuracy in production, find where errors come from, and prove every change against past results.

## What we look for

• You've shipped computer vision into production, beyond a notebook.
• Strong software engineering in Python, C++ or a comparable language.
• A mix of classical vision (geometry, calibration, template matching) and deep learning; you know when each is the right tool.
• Experience with industrial or machine-vision cameras is a bonus.
• You use coding agents to move faster and take full ownership of what they produce.
• You like the physical world: lighting, lenses and parts rotated by 90°.

## Stack

• **Vision:** OpenCV, PyTorch and Lightning, ONNX Runtime on GPU, libtorch from Haskell
• **Cameras:** Basler GigE cameras via pylon, high-speed cameras with GPUDirect capture
• **Services:** Python and Haskell, PostgreSQL, Nix and NixOS
