Professional Background

Prior to joining the SEI, Blanchette was the Deputy Manager of Business Development for Software and Systems Engineering at the Ground Systems Division of United Defense in Santa Clara, California. In this role, he managed the establishment and operation of a satellite office at a customer site. He also developed and executed IR&D programs and reviewed proposals. He joined United Defense in 1996 as the Lead Engineer for command and control software on the Bradley A3 program and rose quickly to the position of Bradley Software Technical Lead, responsible for the schedule, cost, and technical performance of a staff of 40 engineers in the development and integration of software for the entire Bradley family of vehicles. Blanchette received the US Army Achievement Medal for Civilian Service for his work on Bradley. 

Before joining United Defense, Blanchette worked as a senior engineer for Stanford Telecommunications in Sunnyvale, California, where he led a team on an IR&D effort to develop a soldier-transportable terminal for use with the Milstar satellite communication network. He began his career with McDonnell Douglas Helicopter Company in Mesa, Arizona, where he rose to increasing levels of responsibility and leadership while working on diverse engineering, R&D, and proposal programs, culminating in leadership of a small team that developed software for the Longbow Apache helicopter.

Blanchette has over 28 years of experience developing and managing development of real-time, embedded systems in support of US Army programs. His expertise encompasses program and project management, systems and software engineering, command and control, situational awareness, system diagnostics, satellite telemetry, and process improvement.

Blanchette serves as a member of the AIAA Software Systems Technical Committee, a member of the CrossTalk editorial board, and a peer reviewer for a variety of publications and conferences.
