Lifecycle Technical Leadership: Direct designs through formal technical reviews, including System Requirements Review (SRR), Preliminary Design Review (PDR), and Critical Design Review (CDR).

Drawing & Tolerance Standards: Create and review engineering drawings incorporating Geometric Dimensioning and Tolerancing (GD&T) in accordance with ASME Y14.5 guidelines.

Prototyping & Testing: Formulate qualification and acceptance test plans, specify test tooling/fixtures, and lead hands-on testing (vibration, thermal vacuum, shock, environmental).

Vendor & Supply Chain Interface: Coordinate with internal machine shops and external suppliers to procure parts, review vendor manufacturing capabilities, and resolve non-conformances.

Design for Manufacturability (DFM): Work closely with manufacturing engineers to ensure seamless transition from low-rate initial production (LRIP) to full-rate production.

Qualifications:

Required:

Education: Bachelor of Science in Mechanical Engineering (BSME), Aerospace Engineering, or a closely related ABET-accredited degree.

Experience: 5 to 8+ years of relevant mechanical engineering experience in the aerospace, defense, or government contracting sectors.

CAD Proficiency: Advanced proficiency in 3D CAD modeling and mechanical drawing generation (SolidWorks, PTC Creo, or Siemens NX).

Technical Knowledge: Strong foundation in structural mechanics, heat transfer, dynamics, materials selection (metallics and composites), and fabrication processes (machining, sheet metal, additive manufacturing).

Standards & Processes: Proficiency with ASME Y14.5 (GD&T) and familiarity with military standards (e.g., MIL-STD-130 MIL-STD-461, DO-160).

Clearance Requirements: U.S. Citizenship is required. Must possess an active Secret Security Clearance, or demonstrate eligibility to obtain a Top Secret clearance.
