HI

This is Tom from UsNetmetrics. I have the following requirement.

Please send me suitable profiles along with (name, location, status and
number).



*Job Title  : Radio Access Verification Tester*

*Location  : Redwood City, CA*

*Duration  : 6 Months + *





Job Description

looking for a RAT (Radio Access Technology) engineer that will be working
with modem and RIL (radio interface layer) development engineers and will
be responsible for verification of modem and RIL subsystem of smart phones
by developing dynamic test methodologies, scenario, framework, and test
cases, as well as executing tests and analyzing signaling log/data to
ensure the conformance and quality of modem and RIL software.



Must have good understanding of both SW and HW implementation as well as
good command of theoretical analysis of the cellular signaling protocols on
both mobile side and network side Also, the candidate should be working
with the customers  approval / certification engineers running development
level pre-certification tests for all industry's modem and signaling
related conformance and certification tests including but not limited to
CCF, GCF, PTCRB. A RAT engineer will also need to run key portion of
customer test plans prior to customer lab submission for customer
acceptance, to ensure the key telephony features related to modem and RIL
is guaranteed to pass without problem. At certain point of the product
development phase, RAT engineers are required to run RAT NVIOT (Network
Vendor Inter-Operability Test) at selected field to make sure the
successful interoperability of mobile products modem/RIL in any field
condition.



Minimum Required Skills (yrs exp, platforms, languages, tools, etc.):

o             Strong domain knowledge of cellular technologies such as
CDMA1X/EVDO, GSM, GPRS, WCDMA/UMTS, and LTE especially L2-L3 protocol layer
on either network or mobile side.

o             Experience in development and/or testing of signaling / call
processing procedures and protocol on CDMA1X/EVDO, GSM, GPRS, WCDMA/UMTS
and/or LTE.

o             In depth knowledge of 3GPP/3GPP2 Signaling specification.

o             In depth knowledge on Qualcomm development tools and
especially strong ability to analyze QXDM signaling logs.*** Not just
testing but analysis  and working the logs, can be LTE vs QXDM

o             In depth knowledge in 3GPP/3GPP2 conformance test cases, CCF
and GCF/PTCRB and experience of conformance test case execution on test
platforms such as Spirent, Anritsu, etc. and especially manual test
experience and troubleshooting experience on test environment is a plus.

o             Hands on experience in using cellular network simulators such
as Agilent 8960, Anritsu 8470, CMU 200, CMW500 and Spirent

o             Experience in creating cellular signaling test scripts using
scripting environment of Spirent, Anritsu RTD and Anritsu 8470 C, etc.

o             Good understanding and experience of US and International
mobile carriers' test specifications, test cases and execution on live and
simulated networks

o             Strong demonstration of debugging capability in signaling,
connectivity and call drop issues, analyzing data throughput issues and
other product performance issues related to Modem and RIL (Radio Interface
Layer).

o             Experience in development of cellular test automation
framework and environment for Smartphones on network simulators is a huge
plus

o             Knowledge and good understanding of mobile SW /HW
architecture and especially on RIL (Radio Interface Layer) of Android and
other smartphone OS is strongly preferred.
