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. We’re now building the engineering core that will scale it further.

What We’re Looking For

We’re hiring full-stack robotics engineers to keep The Grid operational and push its limits. This is a hands-on, high-impact role based full-time on-site in Western Massachusetts for a minimum of two years. After that, relocation to a future Grid site or a remote transition may be possible.

You’ll be embedded directly in the factory, owning both physical and software systems: tuning camera networks, fixing robot reliability issues, deploying new subsystems, and driving bold experiments to increase throughput. This is not a “write tickets, wait for ops” job. You are the ops.

Who This Role Is For

This role is only suitable for someone who has built full robotic systems —whether as a hobbyist, student, employee, or founder. You’ll be expected to integrate software, hardware, and process into functional systems and debug failures under real-world production pressure.

We don’t hire narrow specialists. We want engineers who can:

*

Diagnose system-wide failures from first principles
\

*

Prototype mechanical and software fixes on the fly
\

*

Work autonomously and communicate clearly to a remote team
\

*

Take full responsibility for uptime and performance in live production
\

Example Tasks

*

Configure and debug a distributed GigE vision system
\

*

Analyze end effector behavior from video and revise its geometry
\

*

Prototype and deploy a new test robot for in-line PCB validation
\

*

Travel to London/Cambridge to brief R&D teams and shape roadmap priorities
\

Why This Role Matters

You’ll be the eyes, hands, and brain of The Grid—directly responsible for keeping one of the most advanced electronics assembly systems in the world operating and evolving. You’ll have board-level visibility and help shape the future of our automation stack from the ground up.

This is a career-defining opportunity for a high-agency engineer early in their career. If you thrive on ownership and solving real problems with real hardware, there’s no better place to be.

What Will Set You Apart

*

Demonstrated ability to build full robotic systems (projects, startups, labs, competitions)
\

*

Strong skills in **mechanical CAD** , **low-level Python or C++** , and **basic electronics**
\

*

Experience debugging production systems under time and reliability pressure
\

*

Willingness to **live and breathe the system** for 2+ years on-site
\

Key Tools & Technologies

*

**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
\

Want to help us build the future of manufacturing?

This underinsurance, coupled with a slow-moving, broker-dominated market, creates a significant opening for innovation. With 77% of Italian consumers expressing high interest in purchasing more policies digitally in the future, and the insurance industry poised to be the second-most impacted by generative AI, the timing is perfect for a disruptive entrant to capture market share.

Tetto Assicurazione: A new kind of home contents insurance for a new generation

Tetto Assicurazione aims to revolutionise the Italian insurance market with a mobile-first, AI-powered home and contents insurance subscription service. Targeting young, urban renters, our platform will leverage large language models and multimodal AI to provide instant quotes, personalised coverage, and near-instant claim payouts. 

By syncing with customers' digital lives, Tetto will automatically adjust coverage as circumstances change, ensuring users are always adequately protected without overpaying. This tech-forward approach, combined with transparent pricing and a user-friendly interface, positions Tetto to become the go-to insurance provider for Italy's next generation of consumers.

What we’re looking for

As part of the founding team you will be an instrumental part of shaping the product & business strategy and will have direct industry experience in financial or insurance data.

• Working with the rest of the team to prioritise our roadmap and deliver the MVP, enabling us to test, iterate and serve our growing membership base

• Ensuring the systems architecture and infrastructure is scalable and can support growth

• Ensuring that the product continues to use best practices, utilising advances in AI / machine learning 

• Feeding into product strategy and commercial goals to identify opportunities to quickly deliver customer value

• Involved in shaping the strategic direction of the business and fundraising process

What you’ll bring

• Demonstrated experience developing complex platforms, integrating distinct data sources and models

• Demonstrated ability to deliver product in a tech startup environment with speed

• Experience of working within an agile environment 

• Knowledge & passion of the challenges involved in developing a FIntech or Insurtech product, including the regulatory requirements and liaising with agronomists/researchers, would be a bonus

• Knowledge of the latest practices in AI / machine learning and can creatively apply them to a consumer application

• Experience with API Integrations to pull data from multiple sources

• Experience building full stack applications (for example HTML, CSS, React, Node js, Python), ideally both web and mobile applications

As garden3d’s Senior Account Lead, you’ll own the end-to-end client experience and revenue portfolio for our 30-person, ~$6 MM/year collective specializing in digital design and development.

You will play a pivotal role in driving account growth, ensuring client satisfaction, and maintaining project profitability. This role is perfect for a strategic relationship-builder with a keen eye for detail and extensive experience managing complex engagements.

💸 Compensation

How we work

We believe that there’s a better balance between the poles of freelancing & full-time, and for that reason, Sanctuary works differently to most shops:

• Transparency & Ownership: We release our Profit & Loss statements to the community each year, open source our best ideas, and talk business & money with everyone in the company. We’re proud to run our business with integrity, and for that reason, we share everything with our team & community.
• **150% Carbon Negative:** Our studio offsets 150% of the carbon we use to do business each year, dated back to our founding in 2015. We turn down work that is not in line with our morals, and we encourage our peers to do the same. We were certified climate neutral earlier this year.
• **Strong Morals:** Since our founding, we've turned down somewhere between $1mm - $2mm of work that didn't meet our moral standards. (Most of that was DTC brands that can't show a valid sustainability initiative).
• Async & Decentralized: We use tools optimized for calm, thoughtful communication, and opt for async whenever possible. We fight hard to maintain our focus time.
• Remote Friendly: Our company is fluent in remote work, making our workplace more decentralized and democratized in the process.
• Ideas & Products: In our spare studio time, we work to build our own open source or internal products to ersify & bolster our income. We create amazing technology products for our clients, so why not for the studio?
