Greater Denver Area

- Oversaw systems engineering for the thermal protection and passive thermal control subsystems on the NASA Orion Crew and service module. - Managed requirements allocated to the subsystems, developed subsystem and interface requirement specifications, and generated six TPS component specifications.- Led the TPS team in a trade study to select heat-shield material, results were consistent with NASA Customer's evaluation. - Ensured Spacecraft requirements were decomposed and flown down to module level and subsystem specifications. - Prepared and presented progress reports to subsystem team members and the NASA customer. - Participated on two Integrated Design Teams to redesign and refine the approach that the Orion Forward Bay Cover is jettisoned. - Reviewed engineering drawings to ensure parts were compatible with interfaces to other subsystems.

Greater Denver Area

- Led multiple systems engineering teams consisting of 7 to 10 engineers. - Ensured system requirements were successfully flown down to subsystems, evaluated system designs to determine if requirements had been met, maintained baseline control of system level requirements and interface control documents, and created and took ownership of several subsystem specifications. - Reviewed candidate changes to system requirements and interface controls, represented the systems engineering team at engineering review boards, provided impact assessments to changes and proposed alternate approaches that were more cost effective. - Planned systems engineering activities, provided status of progress against plans and reviewed design work products to ensure compliant designs were being developed.

Palmdale, Ca

- Led team to develop and evaluate solutions to overcome severe, reflected RF interference on the U-2. - Generated project plans, scheduled resources and ensured the design met customer requirements. - Reported status, analyzed flight test data, managed requirements for updated electronic warfare suite and established risk management plans.- Performed conceptual development for the U-2 Maintenance data processing capability. Subsequently performed systems engineering in the planning and preparation of a Performance Based Logistics proposal for the U-2 program. Generated Statement of Works and Specifications for support contractors and Information Technology providers. Provided Basis Of Estimates for the systems engineering effort.

Owego, Ny

- Led system integration and test efforts associated with the Multi-Mission Helicopter program (MH-60R & CH-60). - Responsible for integration and testing of cockpit avionics and mission sensor systems. - Led regression testing of five software releases. - Reviewed and executed test procedures, planned projects and presented progress against plans to senior management. - Performed planning and budgeting associated with development and production testing.

Portsmouth Uk

- Led Systems Engineering team responsible for the specification, review, and testing of the tactical mission system (EH101 Merlin ASW Helicopter). - Co-Chair of the Systems Engineering Working Group which is held quarterly between Lockheed Martin and the Ministry of Defense. - Systems engineering representative on multiple Integrated Product Teams between Lockheed Martin and suppliers. Ensured overall system integrity while functional teams were performing requirements analysis and design. Subsequent team activity transitioned to resolution of technical issues, prioritize work, plan software content, and deliveries. - Special assignment to update Flight Management portion of the Lockheed Martin ASTOR effort. Included revision of the Segment Specification to reflect revised architecture concept. Assisted engineering manager in the requirements traceability effort and project planning for the performance phase of the contract.
