Antenna Engineer at Onsala Space Observatory

Information about the division
Onsala Space Observatory (OSO, see http://www.chalmers.se/oso) is the Swedish National Facility for Radio Astronomy. OSO is located 45 km south of Gothenburg on the Onsala peninsula and is hosted by Chalmers University of Technology. The observatory operates three radio telescopes at Onsala and is a partner in a sub-millimetre telescope in Chile. OSO additionally plays an important role within several major international radio astronomy projects i.e. within the Atacama Large Millimetre/submillimetre Array (ALMA), the Low frequency Array (LOFAR), Very Long Baseline Interferometry (VLBI) and the Square Kilometre Array (SKA).

Job description
The work focuses engineering efforts related to the pre-construction phase of the SKA (Square Kilometre Array, see http://www.skatelescope.org/) - in particular in the area of the development of Ultra-Wideband Feed for reflector antenna. The work  includes the integration of the feed in cryogenic package together with Low Noise Amplifier. The successful applicant will form part of team working on the design and prototype testing for two work packages for SKA-mid. The work includes EM modeling using simulation software, high-level system modeling, design and testing of locally developed prototypes. In addition work should be done on design improvement for cost reduction and improved product reliability. The position is a two year contract.  Up to 20% of the time will be dedicated to involvement in other projects related to development of new equipment for the OSO telescopes.

Qualifications
Applicants for this post should have a university degree in electrical engineering and at least 3 years of experience in design and testing of feed antennas and microwave components.

Key Competences: 
• Technical expertise in the areas of electromagnetics, antennas and microwave systems.
• Experience in the design of feeds for reflector antenna systems using simulation tools.
• Proficiency with a variety of popular analysis tools such as CST, HFSS, GRASP, FEKO and MATLAB software packages.
• Hands-on experience working in lab environment with the assembly and characterization of antennas and microwave systems. 
• Familiar with RF testing equipment such as network analyzers, spectrum analyzers, signal generators and power meters.
• Comfortable working in a standalone capacity as well as part of a team.
• The post requires a pro-active attitude and the ability to multitask as well as a strong self-motivation and results-orientation.
• Good abilities in spoken and written English. 

Desirable Competences:
• Technical experience in the design of active and passive microwave components.
• Experience in writing technical reports.
• Knowledge of cryogenics, vacuum and thermal modeling.
• Basic understanding of radio astronomy.
• Some experience in mechanical design with Autodesk Inventor.

Application procedure 
The application should be marked with Ref 20140146 and sent electronically via Chalmers webpage.

Application deadline: May 9, 2014. Interviews may start before the application deadline.
