Rolf Siegers joined Raytheon in 1984 and currently leads the company-wide Raytheon Mission Architecture Program and the Raytheon Technology Networks organization.

The Raytheon Mission Architecture Program is a group of enterprise-wide initiatives encompassing architecture process, training and certification, governance, assessment, reference architectures, tools, and collaboration with government, academia, and standards organizations. The Raytheon Enterprise Architecture Process achieved Recognized Method status after undergoing independent assessment, and Raytheon’s Certified Architect Program is the only accredited program in the Aerospace & Defense industry.

Rolf is an Engineering Fellow, Raytheon Certified Architect, current Chair of Raytheon's Corporate Architecture Board, and a prior Corporate Technology Area Director for Architecture & Systems Integration. Rolf has led multi-disciplinary architecture teams for large-scale, software-intensive national and international programs. His experience spans software, system, and enterprise architecture.

Rolf’s professional credentials include:

  • Architecture and Systems Engineering Professional Certificate (Massachusetts Institute of Technology).
  • Software Architecture Professional Certificate (SEI, Carnegie Mellon University).
  • Architecture Tradeoff Analysis Method® Evaluator Certificate (SEI, Carnegie Mellon University).
  • Master-level Open Certified Architect (The Open Group).

Rolf has spoken at technical conferences hosted by Raytheon, U.S. Department of Defense, IEEE, Object Management Group (OMG), International Council on Systems Engineering (INCOSE), Integrated Defense Architectures, The Open Group, System Architecture Forum, and the Software Engineering Institute (SEI) at Carnegie Mellon University. He is a co-chair of INCOSE’s Architecture Working Group, and he holds degrees in Computer Science and Mathematics with Honors from Huntingdon College. He is a member of the Association of Enterprise Architects, IEEE, and WWISA.

Rolf resides in Dallas, Texas with his wife and three children.
