Jonathan Cornwell is a Principal Software Engineer with 12 years of hands-on experience designing and delivering safety-critical aerospace embedded software under DO-178 standards. Based in Florida, he has led development and certification work for rotorcraft and fixed-wing programs—adding high-speed networking interfaces, architecting ARINC/CANBus protocols, and shepherding Level A/B compliance across projects. He blends low-level C/C++ on VxWorks and PPC platforms with systems thinking, having authored tooling for MCDC test generation and driven DO-178 SOI2 audits and process improvements. A practical technical lead and mentor, Jonathan has bridged engineering teams and program management to translate rigorous avionics requirements into verifiable software artifacts. He also brings rare cross-discipline experience from mobile app prototyping to secure messaging and simulator-based prototyping, helping teams accelerate bench-to-flight readiness.
