Experience

• Principal Mechanical Engineer Northrop Grumman · Full-time Feb 2017 – Present 7 yrs 3 mos Melbourne, FL, United States NGAS Advance Programs
  • Structural design technical lead. Lead team of structural design engineers to design and release structural components for an aircraft. Lead responsibilities include design review for all designs & drawings, day to day tasking and mentoring. Created conceptual design layouts, released engineering data and provided product support during installation. Engineering consisted of metallic machined parts and composite structures to be incorporated to the structure of the aircraft. Responsibilities consisted of ensuring all structural designs met program milestones, ease of installation, and maintaining aircraft fatigue and damage tolerance characteristics.
  Integrated large antenna and radar payloads into aircraft primary structure with flawless execution.
  • Designed and created 3D model based definition (MBD) of primary and secondary aircraft structure and creating drawings for metallic (machinings) and composite detail parts and assemblies. 3D released parts with PMI and GD&T incorporated at detail level of design. Created and released 3D PMI for large installations and assemblies. Machined parts consist of bulkheads, frames, keels, straps, gussets etc. Created composite detail parts using Fibersim in Siemens NX. Composite parts consist of laminate skins and core stiffened skins.
