Mechanical Design Engineer

About the Role

Boeing Test & Evaluation (BT&E) is seeking a Mechanical Design Engineer to support the Environmental Test Design Engineering team in Berkeley, MO. This role focuses on supporting St. Louis Environmental Lab testing for local Boeing Defense & Space (BDS) programs. The design team partners with lab test teams to provide necessary designs and hardware for testing. Environmental lab capabilities include vibrational/structural dynamics, acoustic, airflow systems, fuel flow systems, high temperature flow impingement, and environmental control chambers (temperature, humidity, pressure variation).

Key Responsibilities

• Develop mechanical design criteria from customer test objectives/specifications.
• Design mechanical systems, components, test apparatus, and interfaces to integrate test articles with lab and facility infrastructure.
• Create detailed CAD models to support design reviews and fit verification/assembly checks.
• Evaluate material options and suitable fabrication approaches.
• Create detailed fabrication and machine-shop drawings and associated documentation.
• Integrate instrumentation and sensor hardware into mechanical designs.
• Conduct analyses on test hardware including stress, modal, thermal, and fluid-dynamics assessments.
• Provide on-site installation guidance and technical direction to lab personnel during hardware inspection, check-out, and test execution.
• Collaborate with electrical engineers, manufacturing engineers, test engineers, and technicians.

Requirements & Tech Stack

• Ability to obtain a US Security Clearance for which the US Government requires US Citizenship. A final U.S. Secret Clearance Post-Start is required.
• Ability to obtain and maintain access to Sensitive Compartmented Information (SCI) and/or Special Access Program (SAP) access.
• Bachelor of Science degree in Engineering (focus on Mechanical, Civil, Aerospace Aeronautical or Material Sciences).
• Experience with 3D solid modeling software applications (e.g., NX, Catia, CADD).
• Experience in mechanical systems design.

Qualifications

Preferred Qualifications:

• Level 2: 2 or more years of related work experience or an equivalent combination of technical education and experience.
• Bachelor's degree or higher in Mechanical Engineering.
• 1+ years of experience in mechanical system or fixture design.
• 1+ years of experience in test and evaluation.
• 1+ years of experience in stress analysis/structural analysis.
• Proficiency in Siemens NX.
• Experience with machine shop fabrication capabilities including conventional & CNC machining, EDM, mill/lathe, fit/finish tools & processes, and QA inspection.
• Knowledge/familiarity with additive manufacturing processes & tools.
• Understanding of structural dynamics, fluid flow, and thermodynamics theory & application.
• Active U.S. Security Clearance in the past 24 months.
