We live in a mobile device-driven world where the need to a continuously increasing data throughput, un-interrupted connectivity and low latency data exchange are demanding continuously evolving communication techniques and innovation. At Apple, we are committed to develop best-in-class mobile devices that enable simultaneously an un-compromised customer experience and ever increasing battery time. Keeping our commitment is possible by being in the forefront of the innovation, by bringing to our teams outstandingly dedicated and motivated people. The success we are striving is the result of very skilled teams, collaborating in an environment which cultivate creativity, partnership, thinking of old problems in new ways and an un-compromised need for excellence. If that sounds like the kind of environment that you find intriguing, then let's talk.

We are looking to hire an RF System Validation Engineer in a group that develops cellular modems that will be used in Apple's mobile devices. You will be responsible for the validation and optimisation of the receiver embedded in the cellular RF sub-system which is part of different innovative mobile products. Your responsibility will cover all cellular radio access technologies, terrestrial or non-terrestrial communication. Your work will require intensive collaboration with various development or productisation teams across the world.

We are looking for an enthusiastic, experienced and self-contained technical expert who can help us with tomorrow’s challenges!

Description

In the cellular modem development, the RF system is developed, characterised and optimised before it gets integrated into different kind of products. As an RF system validation engineer you have a wide range of responsibility during the complete development cycle. This starts by defining the test scope, planning and developing the tests cases, which are then used to characterise and optimise the RF system. You will own regression tests that monitor the achieved performance during the entire development and productization phase. Your competence and dedication is required to solve very tricky functional and performance failures reported from the product testing and is needed all the way until the launch of the product. Your collaboration skills will enable you to overcome technical challenges which needs to be resolved by different teams located in various locations across the world.

Your role will include but not be limited to the following tasks:

• Definition and planning of the test scope, a thorough study and excellent understanding of the system specifications in order to identify the most relevant and challenging system use-cases.
• Implementation of tests, requiring equally strong RF, HW and SW competences, usage of the cellular system knowledge to conceive meaningful regression campaigns with un-compromised coverage and short execution time.
• Maintain the installed quality gates, constantly appending the coverage in order to address all encountered functional or performance spec failures.
• Characterisation and optimisation of the downlink system performance, following the defined process of the required automation flow, which will help coping with the multi-dimensional solution space.
• Debugging of functional or performance issues, requiring a strong RF expertise with the capability to understand how those RF KPIs can influence the system behaviour.
• Track the status and progress of the project execution, by defining metrics with well defined verdicts.
• Drive RF related problems to a solution involving and collaborating with all relevant colleagues from different disciplines (System Engineering, HW, FW and SW development teams).
• Secure the product validation readiness at the 1st day of the HW availability by Virtual Prototyping.

Minimum Qualifications

Work experience in the RF receiver validation and optimisation, complemented with educational background in RF technology.
Excellent understanding of digital RF receiver implementations and the RF receiverʼs key performance indicators.
Deep understanding in RF fundamentals & RF measurement techniques Experience with the handling of pioneering RF measurement instruments and their automation.
Sound knowledge of cellular 3GPP (2G/3G/4G/5G) RF standards.
Excellent Python programming skills.
Proven multi-functional collaboration experience involving multiple teams and subject areas.
Excellent interpersonal skills and the desire to accept diverse challenges.

Key Qualifications

Preferred Qualifications

A very good understanding of RF cross-talk and RF interference avoidance and mitigation practices is an advantage.
Experience in characterising and debugging RF cellular systems and components, including systematic root-causing abilities.
C/C++ or Matlab knowledge being of advantage.
