Research Engineer/X-ray Sources and Systems

10 May 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, test and develop fabrication processes (glass, ceramic, metal, vacuum sealing) for new x-ray sources
- Design, test and build high voltage power supplies for new x-ray sources
- Design, test and build electronic controls for digital x-ray sources and system products
- Design, test and develop fabrication processes for micro-devices and circuits
- Electrostatic, thermal and mechanical modeling of high voltage vacuum devices
- Make innovative contributions to design team for new x-ray sources and systems
- 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 circuit fabrication, including mask design
- Experience with modeling and design tools such as COMSOL and Solidworks
- Familiarity and preferably experience with field emission devices and high voltage amplifiers
- 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.

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.
