Jeffries Technologies Solutions, Inc. (JeTSI) is an aerospace engineering consulting firm. We bring together experts with a diverse skill set developed throughout their careers within the aerospace industry. Whether working with NASA, NOAA, the Department of Defense, a large prime contractor, or in the private aerospace industry, our consultants have been integral participants in some of the top space efforts of the last twenty years.
Just some of the projects our engineering consultants have been part of include Space Communications and Navigation (SCaN), Space Network Ground Sustainment System (SGSS), Solar Dynamics Observatory (SDO), Cassini-Huygens Mission to Saturn, United States Air Force Satellite Operations, Department of Defense Intelligence, NASA’s Science Mission Support Office, and Mars, Discovery, and Explorer Missions.
JeTSI is an Associate Member with the Consultative Committee for Space Data Systems (CCSDS).
JeTSI was established in 2003 by husband and wife team, Alan and Leslie Jeffries. They decided to take their systems engineering and software development expertise directly to the industry through their own company. In 2013 we celebrated ten years of success working on interesting and challenging space projects, and working with some of the brightest minds in the aerospace industry.
A woman-owned business, JeTSI is headquartered in Herndon, Virginia. From inception until early 2009, the company was comprised of the two owners and a series of engineering services contracts with various NASA efforts, all associated with either the Goddard Flight Space Center or the Langley Research Center’s SOMA. In 2009 our company began to expand its work, growing initially by bringing on consultants to provide short term specialized support to projects. By the end of the year, JeTSI transitioned these consultants to employees and began hiring engineers.
Telework and Green Initiative Pioneer
A pioneer in the area of corporate teleworking, JeTSI engineering consultants work from their home and at client work sites when necessary. We have no brick-&-mortar costs, and instead invest in our corporate computer and communications infrastructure allowing our employees to work efficiently from any location.
This accomplishes two significant goals of JeTSI:
- Providing a balance of lifestyle choices for our career-tested aerospace engineers – empowering them to continue working on challenging projects and sharing their ideas and expertise while living the type of lifestyle they choose; and
- Reducing the carbon foot-print by reducing the number of cars on the road daily and the additional building costs of housing a company. Since our engineers work primarily from home, gas usage and emissions are reduced. With no separate company headquarters building, we save on heating, water, and paper products.
We believe this approach sets JeTSI apart since it reduces enormous energy costs for facilities and commuting, while providing experienced and premier engineering resources to our customers.
Leslie Jeffries is the Chief Executive Officer and runs the business operations, oversees contract administration, and manages the accounting systems. With experience in both the commercial corporate world and government contracting, she controls all cost centers ensuring DCAA practices and requirements are met. Mrs. Jeffries has a Master of Science in Software Engineering from the Volgenau School, George Mason University (2012). Her career prior to founding JeTSI focused on commercial software development for both small and Fortune 500 companies. She is also our Senior Software Developer and Project Leader.
Alan Jeffries is the President and handles JeTSI’s business development, contract development and contract negotiations. He focuses on customer projects, ensuring the best technical content and quality is being provided. Mr. Jeffries 30+ years of aerospace experience enable him to provide and implement solutions with a solid understanding of the technical and business issues facing a company or agency. He has worked on some of the nation’s largest programs, including: the NASA/NOAA JPSS Ground Project, NASA’s Space Network (SN) Ground Sustainment System (SGSS) Project, NASA’s Space Station Freedom (SSF), the DoD’s Global Command and Control System (GCCS) and the DoD’s Strategic Defense Initiative (SDIO). This experience base provides unique expertise in migrating large organizations from a legacy technical baseline to a modernized baseline with minimal cost, risk, and delay.
