Position Title: RF Systems Engineer /Architect

This is a re-scoped replacement position for a RF System Engineer /Architect to work with our multifaceted wireless IC and module design teams:

-          Your objectives will be to define, implement and measure radio system designs for cellular and Wi-Fi,

o   Working with our product centres to define, implement and measure RF-systems.

o   Working with our Architecture team on requirements and specifications for integrated transceiver implementations and their characterisation.

o   Working with our systems team, FW and HW designers to implement on-chip and in-system calibration.

o   Working with our in-house test teams to reduce and improve test times for both self-test and production test.

o   Working with our module teams to reduce BoM and lower power.


This position targets RF Architects and talented RF IC designers wishing to grow into an Architect role. The opening is within the IC-Architecture group in u-blox, based in our Cork IC Design Centre. The IC systems team, are located in multiple sites across Europe and work closely with our three main product centres Cellular, Short Range and Positioning. Their goal is to bring the latest customer and standards requirements into our current and future product designs. The Architecture team then drives these requirements working with the HW and FW designers of the ICS product centre who provide silicon and module designs, for receivers, transceivers, power management and multi-standard, multi-radio modules.

The work is very varied and challenging and includes all aspects of system design from customer requirements to support for high volume products.

If you have a passion for developing cutting edge radio systems and are looking to work in an international team who are focused on delivering the highest quality in radio designs for the latest standards into demanding tier-1 customers, we would like to hear from you.
