High Voltage Systems Engineer

27 December 2017

Stellarray is seeking an innovative engineer for the development of new types of X-ray sources, the integration of high voltage power supplies, and the incorporation of these modules into radiation system products. This engineer will work with a small team of specialists in radiation source engineering, advanced cathode fabrication and test, module assembly and imaging systems. The current focus of our work is the first product we will release – a small irradiator for assuring the safety of blood transfusions, which uses our plain flat panel X-ray sources. We have continuing R & D in other areas, including stationary CT systems using our digital sources, phase contrast imaging and UV sources, to which you would also contribute. Voltages on our X-ray sources range from 10 – 200 kV and input power from 0.1 – 10 kW.


- Design, build, test and integrate high voltage (>20 kV) power systems for new x-ray sources
- Design, build, test and integrate electronic controls for digital x-ray sources and imaging systems using them
- Contribute to design, development and test of irradiator products
- Contribute to development of micro-devices and circuits
- Electrostatic, thermal and mechanical modeling of high voltage vacuum devices
- Contribute to development of fabrication processes for new x-ray sources (glass, ceramic, metal, vacuum sealing)
- Management of structured engineering studies


- A degree, preferably advanced, in Electrical Engineering, Physics, Physical Chemistry, Optics or related field
- A record of successful development of innovative devices (preferably x-ray-related devices but also including MEMS, vacuum microwave devices, flat panel displays, etc)
- Experience with high voltage power supplies and systems
- Experience with modeling and design tools such as COMSOL and Solidworks
- Familiarity with field emission devices and microfabrication processes
- Familiarity with verification and validation protocols under ISO quality regimes
- Training in laboratory and radiation safety
- Familiarity with intellectual property rules and strategies
- Superior oral and written communication skills.

Our 15,000 sq ft facility is located in Austin TX and includes a microfabrication clean room, prototyping benches and tools, panel and system manufacturing stations, machine shop and computer aided design tools.

The job is full-time, requires some light travel, and is both hands-on and managerial. Stellarray offers a competitive salary, health insurance and upside potential with our stock option plan.
