Hardware Systems Engineer

Lumafield•Boston, MA

2d•$105,000 - $150,000•Onsite

About The Position

Lumafield is seeking a Hardware Systems Engineer to join their San Francisco office. This role will be responsible for the breadth of hardware development for a new class of industrial CT scanners, spanning electrical architecture and 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 to carry system-level decisions down to boards, firmware, and integrated prototypes. The role involves working with a small, fast-moving team that values curiosity, rigor, and system-level thinking. This is a full-time, in-person role 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.
Ability to chase ambiguity into the hardware and dig until the system's behavior is understood.

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 on critical components.
Select and qualify critical parts (motors, sensors, actuators, motion controllers, power supplies) and own the rationale and tradeoffs.
Handle light CAD for brackets, mounts, and fixtures, as well as ECAD for embedded platforms and smaller PCBAs.
Build prototypes, including 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 into the design.
