Hardware Systems Engineer

Lumafield•Boston, MA

1d•$105,000 - $150,000•Onsite

About The Position

Lumafield is seeking a Hardware Systems Engineer to join their San Francisco office. This role involves owning the hardware development for a new class of industrial CT scanners, spanning electrical architecture, design, MCU firmware, and system integration. The engineer will partner with other teams to bring prototypes from concept to shipping product. This is a hands-on, interdisciplinary role where the engineer will act as the hardware generalist in San Francisco, collaborating with the Cambridge team. The role requires a systems-level thinker who values curiosity and rigor, working within a small, fast-moving team. This is a full-time, in-person position based in the Cambridge, MA office.

Requirements

Several years of hands-on experience taking a complex electro-mechanical or robotics product from blank page to working hardware.
Breadth of knowledge in mechanical design, electronics, and embedded code.
Comfortable enough in MCAD and ECAD to produce simple designs without handing them off to a specialist.
A tinkerer at heart, with a drive to understand system behavior.
Must be legally authorized to work in the United States without current or future sponsorship.

Nice To Haves

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.

Responsibilities

Drive the system architecture, translating product-level requirements into a clear split across mechanical, electrical, and firmware, and making buy-vs-build decisions.
Select and qualify critical parts (motors, sensors, actuators, motion controllers, power supplies) and own the rationale and tradeoffs.
Handle light CAD work, including MCAD for brackets, mounts, and fixtures, and ECAD for embedded platforms and smaller PCBAs.
Build prototypes by turning wrenches, pulling cables, bringing up boards, and integrating parts into a working system.
Write drivers for peripherals and integrate them into the appliance firmware and application stack with the Systems Software team.
Own test and validation, including planning, fixturing, execution, data analysis, and driving corrective actions.
