Senior Embedded Software Engineer

9/2019 – 7/2024

Radar-based human presence detector. Monitoring heart and breathing rate with a millimeter-wave radar for child presence detection in cars. Software architect/engineer/integrator/tester - I was essentially a one-man software team. What was originally a concept written in Matlab was realized as an embedded system, first on an evaluation kit, later on a series of hardware prototypes aiming for production.

Responsible for everything software, embedded software as well as PC tools, including algorithm implementation, hardware integration and low-level drivers, RF front-end configuration, RTOS integration and start-up behaviour, multitasking over several CPUs, implementing a full CAN stack, API specifications, end-of-line testing in pilot factory, functional safety compliance and preparations for software audit. Colleagues located in Hungary, India and Israel.

9/2015 – 3/2019

Early planning and design of xAF; a platform independent, scalable software framework to be used in all cars for all customers globally. Stakeholder meetings in Detroit, team located in Germany, USA, India and China.

Development of a real-time, network transparent, portable, graphical tuning tool from scratch. Development time could be kept remarkably low and the code base was kept small and concise.

Car audio systems for Aston Martin, Bentley and Volvo/Polestar. Senior embedded software engineer, various roles in various projects. Design and implementation of DSP algorithms, RTOS, system architecture, technical specifications, hardware bring-up and drivers, build system, automated testing, configuration management, documentation - everything between startup and end-of-line production. Teams located in Sweden, Germany, USA, India, and Poland.

3/2011 – 9/2015

Car audio system for several customers, mainly Audi and AMG/Mercedes. Programming a DSP and a microcontroller on custom embedded hardware, using C and assembler language. Wrote the complete code for a DSP, from power-up and onwards, including framework, algorithms, integration and adaptation of third party libraries, et cetera, alone within less than 6 months. Was the sole developer the first year, being responsible for everything from specification to documentation and testing, then did knowledge transfer as new developers were recruited.

Developing a test framework in the form of an emulation running in a Linux environment, thus opening the door tools otherwise not available like Valgrind, and repeatable offline tests for verifying correctness.
