Senior Electrical Engineer I

OXOS Medical, Inc. empowers every provider with the capability, clarity, and confidence to make accurate decisions at the point of care. We are building new kinds of radiographic imaging devices that push the boundaries of previous solutions by improving image quality, reducing radiation exposure, improving ease of use, and building solutions to deliver care outside of traditional scenarios.

We enable anyone anywhere to access radiologic diagnostics at the point of need, expanding availability and changing how healthcare is delivered. In-Person Role Overview OXOS builds radiographic imaging devices that give providers the capability and confidence to make accurate decisions at the point of need. As we scale, we're hiring a Senior Electrical Engineer to own the design of the PCBAs at the heart of our next-generation systems, the boards that carry our high-speed detector and emitter electronics.

This is a hands-on senior IC role. You'll design boards end-to-end: architecture, component selection, schematic capture, layout, vendor management, and hands-on bench bring-up. You're the person who simulates a power stage before committing to a five-figure board spin, who meticulously plans for and designs around EMC compliance early in the design process, and who helps the rest of the team get better.

If you've personally designed and brought up complex multilayer boards in a regulated industry, and you rely on simulation and analysis rather than "build and hope," we should talk. What This Person Will Do Own Projects end-to-end. Take electrical designs from initial architecture through production.

You decide how features and functions get split across boards, select components, capture the schematic and layout of PCBAs, work with vendors to fabricate the designs, then perform bring-up testing on the bench. You will write and execute test plans to verify proper functionality before releasing the design. Simulate before you build.

Our boards are complex and respins are costly, where a single mistake can cost five figures. You'll use LTspice for circuit simulation, and leverage SI/PI tools to validate PCBA robustness up front, so we find problems in simulation instead of on the bench. Design for compliance.

OXOS devices meet IEC 60601-1 (basic safety, single-fault-safe) and IEC 60601-1-2 (EMC). You'll design electrical systems that intrinsically meet these standards, handling high-speed digital and RF signals, and engineering efficient power stages to manage thermal constraints within tightly packed enclosures. Work across the team.

Hardware doesn't exist in a vacuum. You will partner fluidly across Mechanical, Firmware, FPGA, and Systems engineering to ensure your board-level decisions align with broader product goals. Rather than staying siloed, you will negotiate physical and thermal constraints, define complex hardware-software interfaces, and collaborate on overall system architecture.

Requirements

and integration strategies for third-party subsystems like battery packs and displays. Raise the team's bar. Contribute real feedback in team design reviews, audit your own and others' work, and formalize simulation methodologies across the team.

What We Are Looking For

Required: 5 to 7 years designing PCBAs in a regulated industry (medical preferred; automotive or other regulated industry works too). Significant hands-on board-design experience: component selection, schematic capture, layout, DFM/DFA/DFT, and vendor management for complex multilayer boards. Strong signal-integrity and power-integrity simulation experience.

Working knowledge of IEC 60601-1, or equivalent depth in another regulated-industry safety standard. EMC design experience, ideally having supported the physical compliance testing. Hands-on lab skills: fluency with bench equipment for high speed and high power applications, familiarity with soldering and rework down to 0201 passives.

Microcontroller experience (ST family preferred).
