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 $20M from top-tier investors, including Y Combinator and Google Ventures, 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, Elm, 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 and Fast Downward Haskell bindings).
• CircuitHub spans a vast problem space. Challenges include computer vision (OpenCV), machine learning (PyTorch), hard optimization problems (Z3/MiniZinc), 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 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 Boston - 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 the US $130k to $250k, with additional equity.
• CircuitHub has raised $20M 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.
Team/Environment/Role
Our R&D team is fiteen 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
Remote or work from one of our labs in the UK (London, Cambridge) or USA (Boston)
