Summary
👤
SeniorJoseph Stewart is a seasoned Principal Embedded Systems Engineer and Technical Consultant with over three decades of hands-on experience building and bringing up hardware and firmware across consumer electronics, telecommunications, and aerospace domains. He excels at low-level systems work—from bootloaders and bare-metal firmware to embedded Linux/QNX and FPGA bring-up—and has repeatedly been embedded in high-stakes R&D teams at Meta, Amazon Kuiper, and government projects. Comfortable across languages and stacks (C, Python, RTOSes, SQL, JavaScript) he pairs deep systems troubleshooting and software archaeology with pragmatic lab instrumentation and tooling. Joseph’s career shows a rare continuity: long-term mastery of legacy platforms and quick prototyping of novel hardware, plus occasional creative work building custom electronic musical devices. Based in the United States, he combines consultancy agility with principal-engineer rigor to make complex systems actually work in production and prototype alike.
