OHB Italia is seeking for its RF&COMM; team in Milano/Roma/Torino unit anRF COMM Subsystem Engineer m/f Ref. RF_27The RF&COMM; team belongs to the “Engineering Electronics” technical area in the Operations department.
Within OHB Italia operational organization, the RF&COMM; team has the task to define the architecture and performances required to RF communication subsystem which is the spacecraft subsystem in charge to perform data communication from/to Earth and/or other spacecrafts.
The ideal candidate has been working on the architectural design and analysis of Radio Frequency Communication subsystems, along with the definition and specification of the requirements of the elements composing the subsystem and their procurement for use on board the spacecraft platforms.
Familiarity with and knowledge of the elements of the communication subsystems, i.e. antennas, receivers, transmitters, RF passive parts together with modulation formats and coding schemes is an asset.
Experience with complex RF systems in the microwave frequency range in terms of design, development, analysis, manufacturing and verification in conjunction with a solid RF background are an asset. Familiarity with the space business would be an asset but it’s not mandatory.
TasksAs member of the RF&COMM; team, the candidate will be assigned to the role of “Technical Responsible” for the RF Communication subsystem of Space Missions under development at OHB Italia reporting to the RF&COMM; Engineering Manager, with the following main tasks:Architectural design, trade-off analysis, baseline configuration selection and requirements definition of Communication subsystems: Telemetry Tracking and Command,
