Lumius is building fast, smart, accessible 3D ultrasound systems that make real-time volumetric imaging more practical and intuitive. As a Hardware & Embedded Engineer, you will help with the electronics behind our compact ultrasound acquisition platform.
### What you'll work on
* Design and build the the transmit/receive front end, including a high-voltage pulser and transmit/receive switching that protects the receive path.
* Write embedded C/C++ firmware for timing-critical acquisition, peripheral bring-up, ADC interfacing, power states, and BLE/Wi-Fi communication.
* Design compact multilayer PCBs and ICs for different ultrasound systems.
* Build and test the data path that streams ultrasound data reliably from device to application.
* Debug across the full hardware loop: schematic, layout, firmware, measurement, signal integrity, power, and prototype iteration.
### Who we're looking for
* BS or MS in Electrical Engineering or a related field, or equivalent hands-on experience.
* 3+ years building real hardware, especially on ultrasound systems.
* Depth in at least one of RF/analog hardware, embedded firmware, or PCB design, with the desire to grow across the full system.
* Hands-on mixed-signal PCB design experience in Altium or similar tools.
* Strong embedded C/C++ on microcontrollers.
* Comfort moving quickly from design to bench validation, using oscilloscopes, logic analyzers, spectrum tools, and practical measurement .
* A high-ownership builder mindset: you can make progress in ambiguity, communicate clearly, and iterate without waiting for hand-offs.
### Good to have
* Experience with CMUTs, PMUTs, and piezoelectric transducers.
* Ultrasound signal processing.
* Prior experience at an early-stage startup or in a small, high-ownership engineering team.
### Why join Lumius
* Work on the core hardware for a new 3D ultrasound platform at the moment when the architecture is still being shaped.
* Own an unusually broad technical surface area across electronics, firmware, power, wireless, and signal acquisition.
* Collaborate closely with a small founder-led team with deep ultrasound and biomedical engineering expertise.
* Help turn a working medical-device prototype into a compact, reliable platform that can support real clinical workflows.
