Wireless Software Engineer

9/2016 – offen

C++11/Linux SW development for a wireless connectivity solution used in Daimler/Mercedes Benz vehicles
• The project makes use of: STL, boost, proprietary frameworks and also opensource derivatives: Thrift, GENIVI persistence
• Primary focus is on WiFi finite state machines (AP, STA). Interaction with several adjacent areas: communication with 3G/LTE modem, user specific data, etc.
• Technical coordination of a small team (up to 4 engineers) with various levels of seniority: recruitment, technical ramp-up/down, task assignment, code review

8/2012 – 8/2016

Developed a framework for LTE PHY validation involving:
•on-board support for real-time L1 control, statistics collection, profiling data extraction
•C/C++/Linux: L2/3 emulation logic, multithreaded architecture, integration with proprietary libraries (RF, IPC)
•Python: test scenario definition and control of 3rd party validation equipment (mainly Aeroflex TM500C), full automation of test execution
•worked mainly with the following 3GPP standards: 36.2xx, 36.331, 36.321 up to Rel. 10
• The framework is used internally by development/pre-integration/QA teams and marketed as a standalone product
B. Design and development of Physical Layer features in line with 3GPP specifications
•implementation involved coding under a proprietary RTOS running on the StarCore DSP architecture
•alignment with a wireless communication system Matlab reference model
