System Integration and Validation engineer

As a system integration and validation engineer you will be responsible for verifying the firmware and hardware implementation of the Cellular IoT modem, making sure it is compliant with the 3GPP standard and other product specifications. You will be developing the test environments and scripts, analyzing the device and its firmware behavior and identifying issues. You are responsible for the modem software stack quality and conformity.

Having knowledge on 3GPP L1 and/or L2/L3 specification and test requirements, you view the device as ‘white box’. You have understanding of the logs and diagnostic information generated by the modem, you are capable of analyzing them and pin-pointing issues. When the solution is undergoing interoperability and field tests and later on when customers deploying it, you play a key role in issue reproduction in the lab, analysis and debugging.

The platform you will be working is on Altair’s newest chipset, designed especially for the IoT market, highly integrated and consuming super low power. The core technology you will be testing is completely new and exciting!

Tasks
 Integrating, testing and debugging new functions in LTE protocol stack
 Developing core-modem cellular IoT test scripts on eNodeB emulators
 Identifying and debugging issues at the system level
 Developing test campaigns and automated test environment

Requirements
 Student in very late phase of studies or graduated BSC or MSC in computer science or applied mathematics or electrical engineering.
 Knowledge of 3GPP Protocol Stack integration and testing of cellular modems (2G/3G/4G/5G)- Advantage
 Hands on experience in developing automated tests using Python or other scripting language
 You know how to define, develop and organize test campaigns and automations.
 All-around player, capable of understanding and even functioning at multiple layers of the solution (from PHY thru L2/L3 and up to networking)
 Excellent engineering skills – problem solving, pragmatic approach, broad system view
 Good communication skills (oral and in writing) in English
