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.

The Hardware Group is looking for a Mechanical Engineer to help design, prototype, and refine the next generation of our industrial CT scanning systems. You’ll work across disciplines - from motion systems and structures to system integration and user-facing features - to develop reliable, manufacturable, and innovative solutions.
Our product is a complex hardware-software system. Success in this role requires systems thinking, hands-on prototyping, and the ability to bring structure to ambiguous design problems. You’ll collaborate with electrical, firmware, systems, and software engineers to create hardware that’s not just functional, but delightful to use.
This is a hands-on, in-person role based in our Cambridge, MA office.
What you’ll do:Lead the technical aspects of mechanical design for complex assemblies and subsystems, developing well-scoped milestones to deliver on quarter-scale goals.
Accelerate project timelines by leveraging your technical expertise to make informed tradeoffs in scope and execution.
Decompose business goals into technical solutions that can be executed by multiple individuals on the team.
Drive cross-functional collaboration with stakeholders to identify technical needs and develop effective engineering goals.
Unblock yourself and the team by proactively assessing and eliminating the root causes of barriers.
Actively work with and mentor more junior colleagues to help them refine their craft.
About you:Can identify appropriate solutions to ambiguous, under-defined, and open-ended problems.
Excel at navigating ambiguity and remaining resilient through the ups and downs of a project.
Effectively communicate and coordinate requirements with other teams, tailoring your message to the audience.
Consider the short- and long-term impacts of large technology choices.
Serve as a role model for other engineers and model a standard of excellence.
Have self-awareness of your strengths and weaknesses and reliably take action on feedback.
Typically have a bachelor's or master's degree and multiple years of relevant experience executing a broad range of activities directly applicable to the role.
Bonus points for:Experience leading projects through a complete product life-cycle.
Experience designing motion systems, precision mechanisms, or mounting for imaging systems.
Background in industrial automation, inspection, or scientific instrumentation.
Familiarity with tolerance analysis, FEA, or thermal simulations.
A portfolio of mechanical designs, prototypes, or shipped products you can share.

Read LessThe Hardware Group is looking for a Hardware Systems Engineer to join our San Francisco office and own the breadth of hardware development for a new class of industrial CT scanners. You’ll span electrical architecture and design, MCU firmware, and system integration, partnering tightly with other engineering and product teams to bring prototypes from concept through to shipping product.
This is a hands-on, highly interdisciplinary role. You will be the hardware generalist closest to the product in San Francisco, collaborating with our team in Cambridge to carry system-level decisions all the way down to boards, firmware, and integrated prototypes. You’ll work alongside a small, fast-moving team that values curiosity, rigor, and system-level thinking.
This is a full-time, in-person role based in our Cambridge, MA office.
What you'll do:Drive the system architecture. Translate product-level requirements into a clear split across mechanical, electrical, and firmware, and make the buy-vs-build calls on the components that matter.
Select and qualify the critical parts (motors, sensors, actuators, motion controllers, power supplies) and own the rationale and tradeoffs.
Handle the light CAD yourself: MCAD for brackets, mounts, and fixtures; ECAD for embedded platforms and smaller PCBAs.
Build the prototypes. Turn a wrench, pull cables, bring up boards, and bring a pile of parts up to a working integrated system.
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.
Own test and validation. Plan it, fixture it, run it, analyze the data, and push corrective actions back into the design.
About you: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. You don’t need to be the best in the room at any of the three, but you’ve done all three on real products.
Comfortable enough in MCAD and ECAD to produce your own simple designs without handing them off to a specialist.
A tinkerer at heart - you chase ambiguity into the hardware and keep digging until you understand why a system behaves the way it does.
Bonus points for: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.
