Design Engineer PacSci EMC Chandler, AZ, Posted

Position Summary

Pac Sci EMC is seeking a Senior Design Engineer to support the design, development, improvement, production, and sustainment of ordnance components and systems for mission-critical products supporting the U.S. warfighter. This role partners closely with Manufacturing, Quality, Test, and Program Management throughout the product lifecycle. The Senior Design Engineer is expected to operate with a higher level of responsibility, independence, and engineering judgment, requiring less frequent coaching and direction.

• Independently sustain, develop, and improve ordnance product mechanical designs from concept through production.
• Perform engineering analysis, make sound technical decisions, and prepare complete engineering documentation with limited oversight.
• Lead and support production, and sustainment engineering activities.
• Provide day-to-day engineering support to Manufacturing and Quality, independently resolving routine technical issues and escalating higher-risk matters appropriately.
• Lead root cause investigations, implement corrective actions, and drive continuous improvement with a high degree of ownership.
• Maintain engineering drawings, bills of material, and Oracle Agile PLM configuration records with strong attention to configuration control.
• Collaborate effectively with Integrated Product Teams across the product lifecycle and serve as a dependable technical contributor on cross-functional efforts.
• Support proposal efforts, technical evaluations, and engineering decision-making as required.

• Bachelor's degree in Mechanical Engineering preferred. Aerospace Engineering or another closely related engineering discipline may also be considered.
• Typically 5+ years of relevant mechanical engineering, product design, manufacturing support, and/or ordnance design experience.
• Demonstrated experience creating and interpreting engineering drawings and applying GD&T.
• Demonstrated experience with 3D CAD software (Solid Works preferred; equivalent platforms acceptable).
• Strong communication skills, sound engineering judgment, and the ability to work independently within a cross-functional manufacturing environment.

• Aerospace, Defense, ordnance, or other highly regulated product-development experience.
• Manufacturing support experience in a hands-on engineering environment.
• Oracle Agile PLM or comparable product lifecycle/configuration management experience.
• DOE, DFMA, FMEA, failure analysis, thermal/heat-transfer analysis, fluid analysis, or engineering simulation experience.
• ANSYS, Solid Works CAE, or comparable simulation tools.
• Machine shop, fabrication, prototype-build, or other hands-on technical experience.

Senior Design Engineers on this team wear many hats and become technical experts on Pac Sci EMC products. Success in this role requires curiosity, resilience, ownership, strong communication, and sound engineering judgment. The individual is expected to take an assignment, determine an effective path forward, and make meaningful progress with less frequent coaching than a developing engineer, while still seeking alignment when risk, complexity, or business impact requires it.

This role offers continued growth through broader technical ownership, deeper product expertise, New Product Development, Program Management, Quality Engineering, Test Engineering, and future engineering leadership opportunities.

Due to U.S. Government contract requirements applicable to this position, only U.S. citizens are eligible for employment in this role.
