Rockstar🎓
Top SchoolPaweł Dunaj is a seasoned software engineering manager with over a decade of hands-on embedded systems and firmware experience, now leading teams at Google after managing R&D and security disciplines at Nordic Semiconductor. He specializes in low-level C development across Linux user and kernel space, Android, RTOS (vxWorks, QNX), bare-metal and ARM/Zephyr ecosystems, while also contributing in C++ and Java when needed. As a technical leader he has steered line-managed teams through security-focused design and requirements reviews and delivered BLE, DFU and USB integrations for the nRF Connect SDK. His open-source work on Nordic’s nRF repositories improved mbed TLS integration and entropy handling, reflecting a strong focus on practical cryptographic robustness in constrained devices. Paweł blends firmware craftsmanship with people leadership and a project-management mindset from postgraduate studies, making him adept at turning complex embedded security requirements into production-ready solutions. An unusual strength is his long history of alternating deep kernel-space development with higher-level Android and tooling scripts, enabling cross-layer debugging and optimization.
