Engineering & Computer Simulations Inc. (ECS) has added two experienced leaders to support the company’s continued growth and strategic expansion.
Katharine Seaman-Dixon joined ECS on Feb. 16 as proposal manager, and Steve Winkleman joined March 2 as strategic growth and business development officer.
“ECS is expanding its capacity to identify, shape and win work in new markets,” said Gregory Kane, chief operating officer of ECS. “This continued growth builds on our recent award of the One Semi-Automated Forces contract and our ongoing support of training operations in multiple overseas locations under the Warfighter Training Readiness Solutions contract.”
Winkleman is a retired U.S. Army colonel and senior defense executive with extensive experience leading international security cooperation and foreign military sales initiatives. Most recently, he served as a regional director with the U.S. Army Security Assistance Command, where he led a team of more than 70 professionals managing a $47 billion foreign military sales portfolio and supported defense cooperation efforts across the Indo-Pacific, North America and South America.
He previously served as senior defense official and defense attaché at the U.S. Embassy in Argentina, where he led the negotiation and execution of major defense sales, including a $1 billion F-16 fighter jet agreement.
Winkleman will oversee the company’s business development and growth strategy while also representing ECS in the Huntsville, Alabama market. His background in strategic engagement, international relations and complex defense acquisitions positions him to expand ECS’s presence in domestic and global markets.
Seaman-Dixon brings more than 20 years of proposal management and business development experience supporting federal, state and commercial clients. She has led full-cycle proposal development efforts for IDIQs, RFIs and RFPs valued at up to $540 million, achieving a 95% win rate across Department of Defense, Department of Homeland Security, Defense Information Systems Agency and Department of Veterans Affairs opportunities.
Prior to joining ECS, she served as a proposal manager at General Dynamics Information Technology, where she directed cross-functional teams of up to 25 contributors and ensured fully compliant, on-time submissions.
A Certified Federal APMP professional, Seaman-Dixon will lead ECS’s end-to-end proposal operations while strengthening capture alignment, compliance rigor and content management processes across the organization.
