Job Description

Our client is seeking a full-time Senior Mechanical Engineer for the Bridgeton, MO location. The engineer will support mechanical design and platform integration activities while also providing sustaining engineering for released hardware. The role develops and maintains CAD models and engineering drawings, executes engineering changes through configuration control, and resolves build/test/production issues using structured root cause and corrective action methods. This engineer works cross-functionally with manufacturing, quality, suppliers, and systems engineering to deliver mechanically sound, producible designs that meet performance, cost, and schedule commitments. The ideal candidate will demonstrate a consistent ability to operate with minimal supervision, communicate technical risk clearly, and deliver high-quality released designs and change packages on schedule. This contract is expected to last up to 6 months but can turn into full-time employment.

Job Responsibilities

• Support mechanical design and integration tasks for assigned assemblies and interfaces based on system-level and component level requirements
• Create/revise CAD models and drawings; ensure GD&T and documentation quality per standards such as ASME Y14.5-2009 and ASME Y14.100-2013
• Execute ECOs and support CCB/configuration management processes
• Troubleshoot prototype/test/production issues, lead root cause and corrective action
• Collaborate with cross-functional engineering team, manufacturing, quality, and suppliers to implement fixes and improvements
• Develop component designs that are optimized for various manufacturing methods, such as subtractive and additive manufacturing, investment casting, welding, brazing, forming/sheet metal techniques, and other relevant processes.
• Report on engineering task performance against the program schedule using Earned Value methods (e.g., progress status, planned vs. earned, schedule variance) and communicate risks and recovery actions to the IPT lead/program team
• Communicate clearly (written and oral) with other company personnel
• Self-starter who can independently research and quickly build working knowledge using credible internet sources and approved AI tools/agents, then apply findings to engineering tasks with appropriate verification and documentation

Desired Qualifications, Skills, and Knowledge

• Proficient with Creo Parametric - Pro Engineer - and Windchill (or equivalent CAD/PLM tools), including model/drawing release and configuration-controlled updates
• Experience performing system-level integration and/or component-level mechanical design through development, build, and test, including requirements flow-down and interface definition
• Experience conducting structured root cause and corrective action investigations (e.g., 5-Why, Fishbone, fault tree), documenting findings, and implementing fixes via engineering change
• Experience designing and releasing custom fixtures and tooling to support test, evaluation, assembly, and manufacturing (including safety, ergonomics, and repeatability considerations)
• Experience specifying, evaluating, and integrating supplier components/subsystems/services, including technical reviews, requirements/spec compliance, and support to make-buy decisions and supplier issue resolution
