Full-Stack Robotics Engineer Summer 2026 Intern

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 already delivering real revenue. This summer, we’re opening up our factory floor to a select group of interns to work directly on the systems that keep it running.

We’re hiring summer robotics interns to join our engineering team in Western Massachusetts. This is a hands-on role—expect to spend your time embedded in the factory, working on real hardware and software systems, not hypothetical projects.

You’ll help tune camera networks, debug robot reliability issues, prototype mechanical and software fixes, and run experiments to push throughput higher.

This is not a “shadow and observe” internship. You’ll contribute directly to live production.

This role is for students or early-career engineers who have already built real robotic or mechatronic systems—through classes, side projects, competitions, labs, or startups.

We’re looking for people who:

• Think in systems and can diagnose problems from first principles

• Aren’t afraid to get hands dirty with both hardware and code

• Can work autonomously and communicate clearly to a team

• Want to see their work running in production, not just in a simulation

• Configure and debug a distributed GigE vision system

• Analyze end effector behavior from video and prototype design tweaks

• Build and deploy a small test rig for in-line PCB validation

• Collect performance data to inform our automation roadmap

You’ll spend the summer inside one of the most advanced electronics assembly systems in the world. Your work will have real impact on production, not just on a demo bench.

This is a chance to see how frontier robotics and automation actually operate at factory scale—and to get experience that sets you apart from the typical internship track.

• Hands-on experience building robots, automation systems, or mechatronics projects

• Skills in mechanical CAD, Python or C++, and basic electronics/debugging

• Experience troubleshooting under pressure (competitions, labs, hackathons, jobs)

• Curiosity, resourcefulness, and bias toward action

• Python for control and automation

• Beckhoff TwinCAT for industrial PLC integration

• SolidWorks and/or Fusion 360 for mechanical design

• GigE Vision, industrial sensors, motion control systems

Location: On-site in Western Massachusetts
Duration: 10–12 weeks, Summer 2026
Compensation: Paid internship
