Summary
William Killian is a seasoned software engineering manager and hands-on systems engineer with over two decades solving embedded, real-time, and communications challenges across industries from biotech to defense and finance. He blends deep low-level expertise (C/C++, assembly, kernel modules, embedded RTOS) with leadership in vulnerability research and cyber operations, recently managing engineering at Accenture Federal Services after principal roles at Two Six and Peraton Labs. Comfortable across Linux, BSD, Solaris, VMS and legacy platforms, he has repeatedly rescued failing projects, optimized performance at the byte and system level, and designed novel archival and encryption formats for large-scale genomic data. Known for translating ambiguous requirements into practical, auditable solutions, he pairs broad protocol and hardware knowledge (DSPs, FPGAs, UART/SPI/I2C, satellite links) with modern toolchains like Git and automated testing. An uncommon strength is his track record of quick impact: joining troubled programs and delivering production-ready fixes that reduce runtime and resource use dramatically. Based in Reston, VA, he brings a pragmatic blend of research-grade vulnerability discovery and product-focused engineering leadership.
