Hardware Systems 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 San Francisco, CA. and has an office in Cambridge, MA.

About the Role: The Hardware Group is looking for a Hardware Systems Engineer to join our Cambridge office and own the breadth of hardware development for a new class of industrial CT scanners. This is a hands-on, highly interdisciplinary role on a team taking new industrial machinery from concept to production. You will be directly responsible for system architecture, electrical design, embedded integration, and prototype bring-up, while partnering with mechanical, software, manufacturing, and product engineers. You’ll work alongside a small, fast-moving team that values curiosity, rigor, and system-level thinking. If you’re a well rounded electrical engineer, embedded engineer, robotics engineer, or similar, this role is for you. This is a full-time, in-person role based in our Cambridge, MA office.

Drive the system architecture. Translate product-level requirements into a clear split across electrical and firmware. Own designs that meet the requirements.

Select and qualify the critical parts (motors, sensors, actuators, motion controllers, power supplies) and own the rationale and tradeoffs. Make the buy-vs-build decisions on the components that matter.

Write drivers for the peripherals you pull onto the product and land them in the appliance firmware and application stack with the Systems Software team.

Use PCB CAD tools to design embedded electronics and PCBs.

Build the prototypes. Turn a wrench, build cables, bring up boards, and bring a pile of parts up to a working integrated system.

Own test and validation. Plan it, fixture it, run it, analyze the data, and push corrective actions back into the design.

Own your portions of the product through the development cycle, from concept to production.

4+ years of hands-on experience taking a complex electro-mechanical or robotics product from blank page to working hardware.

Breadth of knowledge in electronics and embedded code. You don’t need to be the best in the room at either, but you’ve done both on real products.

A tinkerer at heart - you chase ambiguity into the hardware and keep digging until you understand why a system behaves the way it does.

Enthusiastic about working in a fast-paced, high-ownership startup environment where the work is challenging and rewarding.

Background in motion control, closed-loop systems, or sensor fusion.

Shipped a hardware product from first prototype to production at volume.

Experience with X-ray systems or other radiation-emitting equipment.
