Electrical Engineer

About Lumafield:

Lumafield was founded in 2019 to upgrade manufacturing.


We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.


Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.


We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We're building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.


Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.


About the role:

The Hardware Group is looking for an Electrical Engineer to contribute to the design and integration of the electrical systems that power our industrial CT scanners. You'll be responsible for designing power and control electronics, building test infrastructure, and supporting embedded software across a complex hardware-software product.


This is a hands-on, interdisciplinary role where your electrical designs will tightly integrate with firmware and mechanical systems. You'll work closely with a small, fast-moving team that values curiosity, rigor, and system-level thinking.


This is a hands-on, in-person role based in our Cambridge, MA office.

What you'll do:

• Contribute to the specification and design of electro-mechanical systems
• Perform circuit design, schematic capture, and PCB layout
• Bring up boards and see them through testing and system integration
• Develop test scripts and firmware for factory tools and prototypes
• Collaborate with engineers across disciplines to deliver integrated systems at a challenging price/performance target
• Support your designs from prototyping through to production at our own factory

About you:

• Familiar with ECAD software such as Altium Designer, Cadence, Mentor, KiCad, etc.
• Have experience debugging board-level communication protocols (e.g., I2C, SPI, USB, etc.).
• Have at least basic familiarity with MCU firmware development.
• Comfortable using Python, C, Linux, and basic modern data-science tools.
• Work with your manager to direct your focus and deliver high-quality work that adds value to the team's goals.

Bonus points for:

• Experience working with X-ray systems or other radiation-emitting equipment.
• Understanding of thermal management for high-power PCBs and system enclosures.
• Familiarity with product safety standards (e.g., UL, IEC).
• A portfolio of electronics projects you can share.
