Why join CircuitHub?

This could be huge if on-demand circuit board assembly becomes the default for hardware teams, from first prototype through small batch, with turnaround measured in days. CircuitHub, a South Deerfield electronics manufacturer, ships 81% of full turnkey orders within 3 days, and its $10M Series A, backed by Y Combinator, Plural and Google Ventures, lifts total funding to $46M across six rounds. Eight open roles, seven in engineering, say the team is still building.

JustBacked's take, based on CircuitHub's own site and its funding and hiring data.

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

  • Architect the robot operating system. Design the core abstractions: how robots, cameras, tools and jobs are modelled, how work is planned and dispatched, how state is shared and how failures are handled. Decide what belongs in Python and what needs Rust.

  • Bring in new vision. Integrate novel computer vision algorithms into the control loop, from finding and centring parts to checking every pick and placement, and make them fast and reliable enough for production.

  • Build agentic robotics. Put large models to work in the robots themselves: programming a new part from its datasheet, judging a pick from a camera image, diagnosing a fault and recovering from it, with evals that prove it works before it runs alone.

  • Move a fleet. Route dozens of movers at once without collisions or deadlocks, and coordinate gantries, printers and ovens around them.

  • Bridge to real time. Design clean interfaces between high-level planning and the real-time controllers driving the motors.

  • Make it observable. Simulation, tracing and replay, so every change is proven before it reaches the factory and every failure can be explained.

What we look for

  • You've worked on, and ideally architected, a large-scale robot code base that ran on real hardware in production.

  • Strong software engineering in Python and Rust (or C++ and a willingness to move to Rust). You care about types, testing, concurrency and clear architecture.

  • Experience with some of: motion or path planning, multi-robot coordination, controls, perception, scheduling.

  • Hands-on experience applying large models (LLMs or vision-language models) to robotics, or a strong drive to.

  • You use coding agents to move faster and take full ownership of what they produce.

  • You're happy to visit our factories in the US and UK to see your code run.

Stack

  • Robot software: Python and Rust

  • Vision and models: OpenCV, PyTorch, ONNX Runtime, Claude and OpenAI APIs

  • Planning: multi-agent path-finding, OR-Tools

  • Data and observability: PostgreSQL, OpenTelemetry, ClickHouse

  • Agents: Claude Code and Codex throughout
