Summary
🤩
RockstarStephen Kingston is a multidisciplinary senior engineer based in Cork, Ireland, with three years of professional experience building embedded and backend systems across semiconductor and heavy-equipment domains. He has driven automated verification and test automation for Nordic Semiconductor’s nRF Connect SDK—contributing to porting tests to the ztest API and refining cryptographic hardware test vectors—and now works at Qualcomm. His background spans low-level C/C++ firmware, Rust tooling, CI infrastructure, and end-to-end test solutions including Jenkins, SQL-backed result stores and dashboards, combined with hands-on mechanical and CAD design from earlier roles. Comfortable bridging hardware and software, he has shipped ECU software for Caterpillar Trimble and designed mechanical components and manufacturing-ready parts, reflecting a rare full-product engineering perspective. Outside work he publishes personal projects on GitHub and GrabCAD, signaling a continuous drive to prototype and improve real-world systems.
